Why Is My AC Not Cooling? (Air Conditioner Troubleshooting Tips)

Wednesday, August 14th, 2019
Air Conditioning

In the dog days of summer, it’s frustrating when you must ask, “why is my AC not cooling?” In this blog we’ll review some common causes, DIY fixes and when to call a pro.

There are several reasons a central air system stops cooling effectively, so we’ll begin with steps you can take before you call for AC repair from a professional HVAC contractor.

AC DIY TROUBLESHOOTING TIPS

  1. Check the thermostat
  2. Clear debris from the AC compressor outside
  3. Check the air filter
  4. Verify vents and returns inside are unblocked and open
  5. See if the circuit breaker tripped

IF AC BLOWS WARM AIR OR WON’T TURN ON; CHECK THE THERMOSTAT

In some cases, an air conditioner turns on, but only blows warm or lukewarm air. Why is the AC not cooling? It could be because the thermostat is incorrectly installed or on the wrong setting.

AC Troubleshooting Fix

Verify the thermostat is set on “COOL.” Frequently, the lever or button is accidentally bumped by someone or even a vigorous duster! Plus, it’s easy, during spring and fall when our weather yo-yos a bit, to reset the thermostat after a temperature swing.

Also, check the fan setting. If the fan is set to “ON” instead of “AUTO” it runs 24 hours a day. In other words, the fan runs even when the air conditioner isn’t cooling.

In some cases, the thermostat is installed in a poor location, which impacts its ability to draw a true, ambient average temperature. Thermostats should be in interior rooms, away from windows, or in a hallway. Make sure there’s nothing nearby that could give off additional heat or even cooling, to confuse its temperature sensors.

Conclusion: Set thermostat on “COOL,” and the fan to “AUTO.”


IF AC STRUGGLES, HAS WEAK AIR OUTPUT; CHECK THE AC COMPRESSOR OUTSIDE

The AC compressor unit outside pumps the hot air out of your house when the air conditioner cools your house. If you use a heat pump, the compressor runs all year because a heat pump performs like an air conditioner in the summer but reverses the process in the winter.

In that case, the heat pump draws warm air from outdoors through the compressor and into the air handler where it’s distributed through the ductwork? How is that possible in colder states?

Believe it or not, heat pump technology continues to advance and keep many northern homes comfortable in every season. For example, during extreme temperatures, heat pumps draw on an auxiliary heat source, called electric heat strips. Air passes over the strips, just like a heat exchanger in a furnace, and absorbs the heat.

Regardless, heat pumps use the AC compressor unit all year. Therefore, it needs optimal airflow.

AC Troubleshooting Fix

Walk around the outdoor AC compressor unit. Clear away dirt, debris, fallen leaves and anything that’s collected around it. Too much vegetation or dirt “chokes” the AC compressor. It needs to “breathe” so make sure it’s clean.

  • Locate the power switch; it’s usually inside a metal box near the AC compressor unit. Turn it off.
  • Using a hose, gently spray away pollen, dirt and anything cluttering up the AC compressor fins and the base. Do not use a power washer. That is way too much force.
  • Remove flowers, plants, or shrubs so that the AC compressor has a buffer zone of two to three feet.
  • Make a habit of walking around the AC unit after storms to remove fallen leaves and twigs. It’s easy for twigs, for example, to end up inside the AC unit and cause problems with the fan blades.
  • Trim any nearby branches if they’re leafy, thick or look like they’re dying. All it takes is a good storm and a heavy branch could really damage your AC compressor.
  • When finished, let it dry as much as possible before switching it on again.

Conclusion: Clear away yard clutter and clean the outdoor unit.

POOR AIRFLOW, AC SHUTS OFF EARLY OR AIR CONDITIONER FAILS TO FULLY COOL HOUSE; CHECK THE AIR FILTER

Similar to the AC compressor, your indoor components depend on good airflow. A clogged filter prevents air from easily passing through. The HVAC system strains to force air through the dirty filter. This puts excess wear and tear on your equipment, circulates contaminants and creates a lot of problems, including frozen evaporator coils.

AC Troubleshooting Fix

We recommend you check the filter in your HVAC system every month. Use the arrival of a gas or electric bill as a reminder. Most homes find a filter change every two to three months is sufficient. If your household includes smokers, pets or members sensitive to high pollen and other asthma and allergy triggers, change it more often.

Conclusion: Check your air filter and change it as needed.

AC NOT COOLING, HOT OR COLD SPOTS IN THE HOUSE; CHECK AIR VENTS

It’s common for furniture, drapes or temporary items like toys, to block air vents in the house. Again, obstructions to airflow cause your HVAC system to work harder, increasing the likelihood of an AC repair.

It’s common to have blower motor issues, frozen evaporator coils or water leaking from your air conditioner due to poor airflow. Return vents are usually larger squares or rectangles and draw air into the ducts.

They are sometimes high on the wall, but sometimes below knee-level. Supply vents are the smaller rectangle vents on the floor or up high on the ceiling.

AC Troubleshooting Fix

Walk around the house and check all the return and supply vents. Move anything blocking airflow and make sure they’re open. Sometimes homeowners think closing vents in rarely used rooms saves money. It actually disturbs the air pressure in the home and creates more problems.

Conclusion: Keep air vents unblocked and open.


AC NOT COOLING, WON’T COME ON OR SHUTS DOWN QUICKLY; CHECK CIRCUIT BREAKER BOX

Did you know the most power surges come from within your own home? Sure, lightning and external power grid issues occasionally blast power into your home, but the majority of the time, it’s your own appliances. Large appliances, like air conditioners, push a power surge through the system when they start up. If your air conditioner stops abruptly, it could be an electrical problem.

AC Troubleshooting Fix

Find the main electrical panel for your house and look for circuit breakers in the OFF position. If you’re lucky enough to have clearly-labeled circuit breakers, look for “AC” or “Air Conditioner.” If it’s tripped, push the breaker into the “ON” position and see what happens.

Conclusion: It’s possible a one-time event tripped the circuit breaker. If, however, the breaker immediately trips again when you try to run the AC, turn off the air conditioner and call a professional. It’s likely you have an electrical issue.


COMMON AC NOT COOLING ISSUES FOR PROS

If the DIY AC troubleshooting tips haven’t resolved your issues, it’s best if you call professionals for help. Common air conditioner problems causing your AC to not cool your home include:

  • Refrigerant problems. It could be a leak or low charge. Regardless, refrigerant is a toxic chemical and you don’t want to mess with it. Call an HVAC technician.
  • Fan motor issues. If the fan motor is broken or suffering from electrical issues, it can push cool air through your house. Call an HVAC technician.
  • Bad capacitor. If the capacitor is bad, your AC isn’t getting the power it needs. You need a replacement from an HVAC technician.
  • Worn out AC compressor. The compressor is a major component and often under a separate warranty. Call an HVAC technician to see if it can be saved. If not, you may need to consider an air conditioner replacement.

Weigh the cost of repair against the cost of new air conditioner installation. Consider with a new AC you’ll get a new warranty and if it’s more energy-efficient, lower AC bills immediately.

Why Is My House So Humid?

Wednesday, June 26th, 2019
Air Conditioning

Michiganders understand high humidity is just one of the tradeoffs of living near the Great Lakes, but you may still ask “why is my house so humid?” Unfortunately, proximity to a water source like the Great Lakes increases the amount of moisture in the air and makes the air feel warmer, especially in the mornings.

Humidity tells you the moisture content, or how much water vapor is present in the air. When humidity is high, it feels muggy or “sticky” because sweat doesn’t evaporate easily.

Conversely, when humidity is low, your skin is drier and it’s easier to become dehydrated. Think of winter, when we’re indoors, the air is dry (and colder). We tend to have more issues with dry skin in the winter because more moisture evaporates from our bodies.

In this blog, we’ll review the difference between relative humidity and dew point, what is an achievable and recommended humidity level indoors and how your HVAC system works to control moisture.

DIFFERENCE BETWEEN RELATIVE HUMIDITY AND DEW POINT

Relative Humidity

The relative humidity is measured as a percentage. It defines if the air is saturated. If the relative humidity registers as 100 percent, for example, the air is saturated. If the percentage is 50, it means the air contains half of the water vapor required to be saturated.

As the amount of water vapor in the air increases, the relative humidity increases too. Now, if the temperature drops but the water vapor stays constant, the relative humidity goes up. If the temperature rises while the water vapor is the same, the relative humidity goes down.

Why? Because colder air needs less moisture to achieve saturation than warmer air. For example, in the morning, when the dew is still fresh on the grass, the relative humidity is higher. The morning air is cooler and closer to saturation.

Finally, cold air is denser than warm air, which leaves more room for water vapor in the warm air of summer.

Dew Point

Although you’ve probably heard someone say, “it’s not the heat, it’s the humidity,” dew point is actually a better marker of humidity because it’s not dependent on temperature.

The dew point is the temperature in which the air must cool in order to be saturated. Below the dew point, water condenses from the air to surfaces, like the morning grass. Because it’s not related to temperature, the dew point doesn’t change as much during the day. So, in short, the answer to why is my house so humid is simply the air is nearly or fully saturated.

RISKS OF TOO MUCH HUMIDITY

When the humidity is high indoors, your home runs into certain risks including poor air quality. High indoor humidity often causes:

  • Mold and mildew growth
  • The right environment for dust mites to multiply
  • Insects and rodents seeking moisture. They leave behind droppings, nesting material and other particulates in your ventilation.
  • Cupping in hardwood floors and warping of wooden doors, door frames, and more
  • Uncomfortable living conditions for those with certain respiratory or cardiac conditions.

Humidity increases breathing difficulties for people with asthma, COPD, congestive heart failure and other conditions. Excess humidity increases allergy and asthma triggers like dust mites and mold and mildew spores.

HOW HUMIDITY AFFECTS COOLING

Too much moisture in the air traps heat and makes it feel hotter than the actual temperature. Therefore, it’s important to invest in an air conditioner or heat pump to both cool and dehumidify your home. Michigan weather might be great for growing blueberries, but if it’s humid inside, it may be hard to be comfortable and sleep well.

Humans cool their bodies by sweating. However, if there’s a lot of water vapor in the air, sweat can’t easily evaporate off our skin. At 100 percent relative humidity, for example, sweat won’t evaporate at all because the air is already completely saturated with water vapor.

Many people have ceiling fans to cool their homes, however, it is important to understand that fans do nothing to cool the air. They, in fact, provide a breeze to help your perspiration evaporate easier. They don’t cool the air, they help you feel cooler.

HOW AIR CONDITIONERS COOL YOUR HOME

Your air conditioning unit does more than just blow cold air into your home. It extracts heat and water vapor from the air to meet the temperature set by the thermostat. Inside your air conditioning unit are coils filled with refrigerant.

Refrigerant is a substance which moves back and forth between liquid and gas states to absorb and release heat. As the hot humid air from inside your home passes over these coils, the liquid refrigerant absorbs the heat and turns it into a gas.

To keep your home at a cool temperature, the air conditioner compresses the air inside the coils until it returns to liquid. The extra heat generated by compressing this gas releases outside the home via condenser coils and a second fan.

HOW AIR CONDITIONERS REDUCE HUMIDITY

High humidity makes the inside of your home feel clammy. Fortunately, an air conditioning unit extracts moisture with an evaporator coil. As humid air passes over the evaporator coil, it condenses and drains into a condensate pan.

To avoid water damage, keep an eye on your condensate pan. If you find water around your indoor air handler or suspect a clog in the line, call A-1 Mechanical for assistance. A small amount of water can easily create thousands of dollars of damage.

How to Prevent Air Conditioner Damage to Save Money

Tuesday, May 14th, 2019
Air Conditioning

A quality air conditioning unit lasts for more than a decade. Air conditioning provides an oasis from the extreme heat of summer. Providing both comfort and security for your family is important. Your HVAC system is an expensive investment so it’s critical to know how to prevent air conditioner damage. Wear and tear over time results in high energy bills, and expensive air conditioner repairs may even result in premature air conditioning replacement in the future.

There are many factors that can damage your air conditioner. Both the summer sun and the frigid winters can weather your AC unit. Your HVAC unit has many moving parts which mean neglecting the air conditioner can lead to damage. A dirty HVAC system that frequently breaks down is also more prone to require replacement. A-1 Mechanical stresses the importance of properly maintaining your air conditioner to get the most out of your HVAC system.

5 Steps to Prevent Air Conditioner Damage

There are a number of key tips on how to prevent air conditioner damage and save money every month and for the lifetime of your equipment. As a local Lansing, Michigan HVAC contractor A-1 Mechanical provides our extensive experience and knowledge to help you save money. For many homeowners your HVAC system can benefit from following these steps:

Protect Your AC Unit with a Cover

When the AC unit is dormant in the late fall and winter, a protective cover prevents elements like rain, snow, leaves, and dirt from directly damaging your AC system. As we transition into warmer weather in Lansing and Grand Rapids, people seek comfort from their air conditioning units to keep them cool. Of course, you must remember to protect your unit with a cover in the fall and remove the cover from the AC unit before turning on the air conditioner.

A cover helps prevent air conditioner damage when used properly. A common mistake is to turn your air conditioning on while covered, which causes the unit to overheat quickly. This usually becomes a costly mistake if parts are ruined due to overheating. In some cases, the damage requires an air conditioning system replacement.

Inspect Furnace Filter Monthly

One of the easiest ways we know how to prevent air conditioner damage is to check your HVAC unit’s air filter every month. A dirty air filter chokes the components within the air handler and ductwork. This causes airflow to be restricted. Many furnace repairs can be linked to a dirty filter. A clean air filter helps your AC unit remain energy efficient and improves your indoor air quality.

This is simple air conditioner maintenance you can do yourself. When the filter is clogged, your system works harder to push air through it to heat or cool your home. This strains the system and ages it faster. It also requires more energy which increases your utility bills. Finally, it speeds up the path to increased repairs and even breakdowns. When you look at your air filter, first take note of any dirt or dust collected in the filter. If there is a significant amount, replace it with a new filter. Since air filters help to reduce energy costs, many homeowners choose to replace air filters monthly.

When purchasing a new furnace filter, each manufacturer recommends a compatible filter. There are many filters in the marketplace that make many claims. Always defer to the manufacturer of your HVAC system. Making sure you get the right filter type as well as a filter with the right dimensions ad type. Different types of furnace filters include fiberglass, pleated, and media. The wrong air filter can damage your air handler and air conditioner. By trusting the manufacturer your air conditioning runs properly, reduces energy bills, and prevents breakdowns.

Regularly replacing your furnace filter with the proper filter maintains the energy efficiency of the HVAC system and prevents excess wear and tear.

Clean The Outdoor Unit

Outdoor AC compressors lose airflow and thus, energy efficiency when leaves, dirt, dust and other debris collect on it. There are many sources of airborne debris that can clog your system and impact compressors. This is because the clogged air conditioner vents can’t circulate air efficiently. This, similar to a dirty air filter, causes the unit to work harder to produce the same cooling results. Cleaning restrictions from around the unit is a simple chore to perform weekly as part of your yard work. Clean systems produce cold air more efficiently and save energy.

Airborne debris also settles on air conditioner coils. Dirty air conditioner coils create an insulating effect. This makes it hard for the unit to vent the heat from your home to the outdoors. This increases cooling costs and impacts the comfort throughout your entire house.

Anytime you are in your backyard and especially after severe storms, make a quick check around your AC compressor. Specifically, pay attention during the spring storm season and during the autumn months when leaves are falling. Beware of ice on your AC unit and after the snow melts.

Inside your home keeping the area around your air handler is also important. You should think of your entire system as benefiting from steady airflow that is clean. Air will never be completely free of particulate but the cleaner you keep the area around your equipment, inside your system, and within your home, the better performance and indoor air quality.

Install Smart Thermostat

You’re probably already aware of the benefits of programmable thermostats and home automation systems, but there are certain things to keep in mind. For example, if you set your thermostat too low, you may decrease the lifespan of your AC unit through overuse. Each degree can save energy.

Programmable thermostats are helpful when you have a set work schedule. Programming your thermostat to use less energy is powerful. Using your air conditioning when you are not home is a waste of money. For many homeowners and busy families your life is not set by a work schedule, though.

Smart thermostats save on air conditioning bills by adapting to your actual activity. The smart thermostat adjusts your AC unit to respond when you leave your home. The less your air conditioner works the longer it lasts.

Schedule Annual Air Conditioner Maintenance

The final piece of advice on how to prevent air conditioner damage is to schedule preventive air conditioner maintenance. While these other steps are important DIY steps, professional HVAC maintenance is valuable for saving energy. Calibrating your system with professional HVAC professionals each spring assures your system maintains warranty and prevents surprise breakdowns.

Each brand of air conditioner requires unique steps. Professional HVAC technicians at A-1 Mechanical follow manufacturer guidelines and perform our thorough processes. Our experience and training guide our vision for helping homeowners achieve better performance and prevent air conditioner damage.

With a regular maintenance plan with a licensed heating and air company, you catch minor air conditioner problems before it needs more expensive repairs.

Choosing the Right Air Conditioning Unit Replacement

Tuesday, May 14th, 2019
Air Conditioning

Since air conditioners are an investment in your home, it makes sense that you would want to do your research before spending all that money. A licensed cooling system technician will be able to help you pick the best air conditioner for your budget and home cooling needs.

ENERGY EFFICIENCY

When browsing new air conditioners, be sure to look at their Seasonal Energy Efficiency Ratio (SEER) rating. The government has recently required all air conditioners to have a SEER rating of 13 or higher. If an air conditioning unit has a rating anywhere between 14 and 22, then you can be sure it is energy efficient. If an air conditioning unit has a rating anywhere between 14 and 22, then you can be sure it is energy efficient.

High SEER ratings are reflective of high energy efficiencies. This means that for the same amount of energy, an energy efficient air conditioner puts out more cold air for the same cost as non-efficient models.

PRICE

When shopping for a new air conditioning unit you will have to consider both the price of the unit and the cost of installation. While some homeowners try to save money by purchasing a new air conditioning unit on their own, we don’t’ recommend it. If you are unsure what size air conditioner to purchase for your home an experienced heating and cooling contractor can help you find the right size air conditioner within your price range.

You’re better off paying money for a licensed HVAC contractor to help you pick out an appropriate central air conditioning model than to be stuck with an expensive cooling appliance that doesn’t work properly.

SIZE

The air conditioning unit size must be proportional to the size of the house; otherwise there will be complications with your residential heating and cooling system. For example, if you get a unit that’s too small for your house, it will not be big enough to provide cool air to your entire home. On the other hand, if you purchase a unit that’s too big for your house, you will end up reducing your energy efficiency and paying higher energy bills for all the electricity your oversized unit uses. This is because units that are too big for their respective houses frequently turn on and off.

Before taking a recommendation from a HVAC professional, make sure that they first do a load calculation to determine the best size air conditioner for your home. A load calculation for air conditioners takes into account the square footage of your home, along with other factors such as insulation.

Air Conditioning Tips for the Cooling Season

Tuesday, May 14th, 2019
Air Conditioning

With summer rapidly approaching, many homeowners are getting ready to run their air conditioner units full time. However, before making that switch, be sure to check out our tips for how to make your home more energy efficient and save money on energy bills. It’s always good practice to schedule preventative air conditioner maintenance before the hottest months of the year. That way, you won’t be stuck sweating in July while your neighbors enjoy air conditioned comfort.

Hiring a licensed heating and cooling technician to inspect your air conditioning unit can help save you money in the long run.

CHECK FILTERS MONTHLY

Air conditioner filters are responsible for catching any dust and other airborne allergens from entering your home. While this is great for improving the air quality in your home, it’s also important to check your air filters once a month. When a filter is clogged, it blocks the flow of air. This causes your air conditioning unit to work harder in order to compensate for less air passage.

Checking the filters monthly is a simple way to ensure your energy efficient air conditioning unit keeps running efficiently. If you notice a lot of dust and other debris in your filter, be sure to change it. Changing an air conditioning unit filter is simple enough that you can do it on your own without calling an air conditioning repair technician.

CLEAR DEBRIS FROM OUTDOOR UNIT

Over time, dirt, dust, leaves, and other outdoor debris can collect on your outdoor air conditioning unit to block the transfer of cool and warm air. When the air conditioner isn’t able to run at full capacity, it is forced to work harder to put out the same level of cool air. This decreases your home’s energy efficiency.

To save money on your next energy bill, make sure that you check your outdoor unit to make sure there are no obstructions. This is a good thing to check for during the autumn months when the leaves start to fall. You should also check once the snow melts in the spring.

BLOCK OUT HARSH SUNLIGHT AND RUN FANS

Sun streaming through your windows brings natural light to your home. However, these sun rays also carry heat, which can quickly increase the temperature in your home. To combat this problem, be sure to close your blinds when the sun reaches its peak.

We also advise that you run fans to help circulate the air in your home and create a wind chill effect. If your home has a second story, you may want to strategically place extra fans to account for the fact that heat rises. Well-placed fans for cooling are usually enough to keep your home at a comfortable temperature during the cooling season.

TAKE ADVANTAGE OF COOL MORNINGS AND NIGHTS

If you’ve lived in Michigan for long enough, you know that the spring and fall months are known for their cool weather patterns. Take advantage of these cool mornings and evenings by opening up the windows to let in fresh air.

Not only does fresh air have a lot of health benefits, but it will also help decrease the burden on your air conditioning unit. Whenever you can let Mother Nature cool your home, you should take advantage. Especially since these opportunities will fade by the time summer comes around.

SCHEDULE AIR CONDITIONER SERVICE

With any heating or cooling appliance, it’s important to invest in regular maintenance so that it will last for as long as possible. Air conditioner replacement can be a financial burden on families, which is why it is important to keep it running effectively and efficiently by scheduling air conditioning maintenance checks so that any minor issues can be fixed before they grow into larger, more expensive, HVAC repairs.

If you are interested in scheduling an air conditioning repair or maintenance visit, please feel free to call our licensed Lansing HVAC technicians at (517) 272-8629.

Is My Air Conditioning Unit Oversized?

Tuesday, May 14th, 2019
Air Conditioning

Air conditioners are designed to both cool and dehumidify your home. However, oversized air conditioners aren’t able to run long enough to remove the humidity from your home. Below, you will find the top signs your air conditioner is too big for your home. For more information, we recommend you call a reputable heating and cooling contractor in your area.

YOUR HOME HAS HIGH HUMIDITY

Your home feels humid, but lowering your thermostat has no effect. In order to best cool your home, you need an air conditioner that will be able to run long enough to have an effect on the humidity. An overpowered air conditioning unit will be able to cool your home in a short amount of time. However, they don’t run long enough to get rid of the mugginess.

Just because an air conditioning unit is bigger, doesn’t mean that it’s better. An effective A/C will run for a period of time long enough to effectively cool and dehumidify the air. An ineffective A/C will turn on long enough to satisfy the temperature setting on your thermostat, but not long enough to give you relief from the indoor humidity.

THE FAN CONSTANTLY TURNS ON AND OFF

Air conditioners come in different sizes to accommodate the different sizes of homes and commercial buildings. However, when an air conditioner is too big for its respective building, it lowers the temperature too quickly. While instant coolness may not sound like a bad thing, keep in mind that this also results in shorter cooling cycles and fluctuating indoor temperatures.

Having a comfortable home relies on being able to maintain a steady indoor temperature. To resolve the issues associated with your oversized air conditioning unit, we recommend you contact an experienced cooling systems company in your area.

YOUR ENERGY BILLS ARE HIGH

Whenever your air conditioner turns on and off, it consumes energy. This means until you resolve the issue of having an oversized air conditioner, you will be paying too much for your energy bills each month. High energy bills are just another sign that your inefficient air conditioner could be too big for your home or commercial building.

To fully understand the inefficiency of oversized air conditioners, compare how your A/C is run to how you drive your car. Have you ever noticed that you get more miles per gallon when you drive on the freeway? This is because driving at a constant speed uses less energy than when you have to constantly stop and go.

The same principle applies to your air conditioner unit. Energy efficient air conditioners will run for long uninterrupted periods of time to effectively cool and dehumidify your home. To increase the energy efficiency of your home, we recommend hiring a qualified HVAC technician to do load calculations. Load calculations ensure that you install the right size A/C for your home.

If you want to learn more about our oversized air conditioner services, please feel free to give our Lansing cooling system technicians a call at (517) 272-8629.

3 HVAC Systems for New Home Construction

Tuesday, May 14th, 2019
HVAC Systems

Are you trying to decide on a HVAC system for new construction? This is an important decision that can impact how much you pay for future energy bills while keeping your home at a comfortable temperature year-round. In this blog post, we will go over three different types of heating and cooling systems for your new custom-built home. For more information, we recommend getting in touch with licensed heating and cooling contractors near you with experience in new home construction.

DUCTLESS SYSTEMS

Ductless systems allow you to create zones of comfort in your home. Do you or a family member prefer a lower temperature setting than the rest of the family? No problem. A ductless heating and cooling system allows you to set different temperatures for different areas of your home.

Ductless HVAC units are more energy efficient than their ducted counterparts because no energy is lost while traveling through the ducts. Preventing energy loss can help you save money on utility bills over time. Ductless systems are also quieter than other HVAC systems, which can make for a more peaceful home.

Having control over temperature settings throughout your home can even help you save money on energy bills. For example, you may want to set the upstairs ductless HVAC units for a lower temperature in the summer to account for the fact that heat rises. Units downstairs can be set at a higher temperature.

FURNACES

Gas furnaces work by safely igniting gas via the pilot light to heat air. This air is then forced through the vents in your home to provide warmth in the winter. You are able to control when your furnace turns on through the thermostat. For example, the furnace will only kick on if the temperature in your home drops below the programmed temperature.

Furnaces are a reliable way to heat your home during the long winter months. However, you’ll also need to install an air conditioning unit to keep your home comfortable in hot weather. A heating and cooling contractor can let you know what HVAC systems work well in your climate.

HEAT PUMPS

Did you know that the temperature underneath the surface of the earth stays around 47 to 50 degrees Fahrenheit year-round? Heat pump systems take advantage of this by pumping hot air out of your home in the summer and warm air into your home in the winter. If you decide to install geothermal heat pumps, your contractor will need to dig holes near your house where the pipes will be installed. Heat pump installation is much easier when building a new home because you don’t have to worry about how it’ll affect landscaping.

The Lansing heating and cooling contractors at A-1 Mechanical are dedicated to helping homeowners make informed decisions during new home construction through quality furnace installation and air conditioning installations services. If you are interested in learning which heating and cooling system is best for your custom built home, give us a call at (517) 272-8629.

Why is Your Furnace Blowing Cold Air?

Tuesday, May 14th, 2019
Furnace

When the temperature drops outside, the last thing you want to deal with is a gas furnace that doesn’t work. We understand the frustration homeowners feel when they have to schedule furnace repairs, which is why we always strive to let homeowners know what they can do to prolong the lives of their furnaces.

In this blog post, the Lansing furnace repair contractors at A-1 Mechanical will go over the reasons why your furnace is blowing cold air so you can keep your home comfortable year-round.

THERMOSTAT IS SET TO “ON”, NOT “AUTO”

If your furnace is blowing cold air, don’t panic. The solution may be simpler than you think. Before calling a heating and cooling company, check to see that your thermostat is set to “AUTO”. This will be the first thing a furnace repair contractor checks.

Your furnace is designed to kick on once the temperature inside your home drops below the programmed temperature setting. When the thermostat is programmed to “AUTO”, this means the furnace blower will only push air through the vents when the burners are on.

If the thermostat is set to “ON”, the furnace blower will constantly push air through the vents, regardless of whether it’s heated or not. Changing this setting yourself is simple and can save you the cost of having a HVAC repair contractor come out to your home.

FURNACE OVERHEATED

You’ll know your furnace has overheated if you notice it blowing hot air, then cold air, before stopping completely. As a safety precaution, your furnace will automatically shut off the burners and continue running air to cool down the unit. Your furnace completely shuts off once it has reached a safe temperature.

A common reason why furnaces overheat is dirty air filters, which block airflow and cause your furnace to work harder to produce the same amount of heated air. If you recognize the signs of an overheated furnace, call a furnace repair company as soon as possible. A dirty air filter is easy and inexpensive to replace compared to having to repair the heat exchanger.

PILOT LIGHT IS OUT

The pilot light is responsible for igniting the gas in your furnace and heating air. However, if the pilot light is out, your furnace will only be able to blow cold air. Each furnace is a little bit different for how to light the pilot. Be sure to check with the manufacturer’s instructions before attempting to light a gas furnace. If the pilot light refuses to stay lit, you’ll need to call a furnace contractor to fix any issues with the thermocouple. While minor issues can be handled by experienced homeowners, you should always call a professional for any residential furnace repairs outside your comfort zone.

The HVAC technicians at A-1 Mechanical want to make sure your HVAC system doesn’t surprise you with sudden costly repairs. If your home could benefit from any of our furnace installation and replacement services or furnace repair services, please contact our Lansing heating and cooling contractors at (517) 272-8629.

Air Conditioner Maintenance Tips to Save Money

Tuesday, May 14th, 2019
Air Conditioning

Given the hot summers in Michigan, most homeowners run their air conditioners until late September and easily forget about air conditioner maintenance until it’s too late. What if you had air conditioner maintenance tips to guide you? Did you know the neglect of your AC costs you in the long run?

Fortunately, A-1 Mechanical’s qualified HVAC technicians help you catch small issues before they turn into expensive air conditioning repairs or worse, breakdowns. Air conditioning service also ensures your unit runs as efficiently as possible which saves you money on energy bills.

To make preventive maintenance super easy, join one of our maintenance plans. We offer a couple of options for homeowners and customized plans for commercial HVAC clients.

Continue to learn our 5 best air conditioner maintenance tips.

1.) CHANGE AIR CONDITIONER FILTERS

We often sound like a worn out 45 record on this topic, but it’s so important. As the name suggests, air conditioner filters block dust and other airborne allergens like pollen, dust mites, pet hair and dander.

However, if the filter is clogged, it can’t continue to do its job. A dirty filter blocks airflow and forces your air conditioner to work harder to produce the same amount of cool air. Check it monthly and change the air filter if it’s dirty.

Don’t be surprised if you have to replace your filters more often during the cooling season. Early spring in Michigan means more mold spores are in the air as the ground thaws and exposes damp and decaying leaves.

As the weather warms tree pollen and other triggers join the allergy party. Changing an air conditioner filter is simple. One way to remember is to check each month when your utility bill arrives. If you’re unsure, ask your HVAC technician next time he or she visits for a tune up.

2.) CLEAR DEBRIS FROM THE OUTDOOR UNIT

Be sure to clear the outdoor AC unit of anything which blocks the heat transfer needed to cool your home. During the autumn, it’s common for fallen leaves to cover your AC unit.

Likewise, make sure the AC unit is clear of grass clippings after mowing your lawn. It’s also wise to avoid cutting grass while the compressor is running, if possible. You don’t want clippings getting sucked into the AC compressor.

Walk around the AC unit after severe weather and clear away yard waste like fallen leaves and twigs. Also, landscape carefully. Avoid the temptation to camouflage the AC unit with shrubbery or fencing.

AC compressors should have two to three feet of clearance for optimal airflow. Why is this important? When debris blocks the outdoor air conditioning unit, the system uses more energy to produce the same amount of cool air.

The energy efficiency and lifespan of your air conditioner decreases when it’s forced to work so hard. To save money on your next energy bill, make sure nothing is blocking the outdoor unit.

3.) CLOSE BLINDS AND RUN FANS

We recommend keeping the blinds closed during the hottest part of the day when the sun reaches its peak. The heat carried by the suns rays quickly heats up your home and makes it uncomfortable during the summer months.

Fans, however, circulate cool air throughout your home to create a wind chill effect. Don’t pay to run the fan if no one’s in the room because they don’t cool the room. They cool the people in it by speeding evaporation of perspiration.

If you live in a two-story house, you’ll want to place extra fans on the second floor. Fans can help keep your home at a comfortable temperature during the summer while reducing stress on your air conditioning unit.

You might consider planting deciduous trees or shrubs. In the summer, they block direct sun from your south-facing windows. In the winter, when they’ve lost their leaves they let the warmth of the sun inside.

4.) OPEN WINDOWS ON COOL DAYS

Your air conditioner will last longer if you only use it on hot days. When the temperature is cool outside, shut off the AC and open up all the windows. The cool fresh air will help you save money that you would have otherwise spent on running your air conditioner.

During early summer, you may be able to get away with leaving the windows open in the mornings and evenings. However, the opportunities to let in cool fresh air quickly fade by the time summer arrives and are less of an option if you live with allergies.

5.) INVEST IN AIR CONDITIONER MAINTENANCE

No homeowner wants to pay for premature air conditioning replacement, which is why we recommend investing in maintenance. It’s truly one of our best air conditioner maintenance tips!

Our HVAC technicians catch minor issues before they snowball into expensive and inconvenient repairs. Air conditioners with regular maintenance run efficiently, cost less to run and last longer.

Why Is My House So Humid?

Tuesday, May 7th, 2019
Air Conditioning

Michiganders understand high humidity is just one of the tradeoffs of living near the Great Lakes, but you may still ask “why is my house so humid?” Unfortunately, proximity to a water source like the Great Lakes increases the amount of moisture in the air and makes the air feel warmer, especially in the mornings.

Humidity tells you the moisture content, or how much water vapor is present in the air. When humidity is high, it feels muggy or “sticky” because sweat doesn’t evaporate easily.

Conversely, when humidity is low, your skin is drier and it’s easier to become dehydrated. Think of winter, when we’re indoors, the air is dry (and colder). We tend to have more issues with dry skin in the winter because more moisture evaporates from our bodies.

In this blog, we’ll review the difference between relative humidity and dew point, what is an achievable and recommended humidity level indoors and how your HVAC system works to control moisture.

DIFFERENCE BETWEEN RELATIVE HUMIDITY AND DEW POINT

Relative Humidity

The relative humidity is measured as a percentage. It defines if the air is saturated. If the relative humidity registers as 100 percent, for example, the air is saturated. If the percentage is 50, it means the air contains half of the water vapor required to be saturated.

As the amount of water vapor in the air increases, the relative humidity increases too. Now, if the temperature drops but the water vapor stays constant, the relative humidity goes up. If the temperature rises while the water vapor is the same, the relative humidity goes down.

Why? Because colder air needs less moisture to achieve saturation than warmer air. For example, in the morning, when the dew is still fresh on the grass, the relative humidity is higher. The morning air is cooler and closer to saturation.

Finally, cold air is denser than warm air, which leaves more room for water vapor in the warm air of summer.

Dew Point

Although you’ve probably heard someone say, “it’s not the heat, it’s the humidity,” dew point is actually a better marker of humidity because it’s not dependent on temperature.

The dew point is the temperature in which the air must cool in order to be saturated. Below the dew point, water condenses from the air to surfaces, like the morning grass. Because it’s not related to temperature, the dew point doesn’t change as much during the day. So, in short, the answer to why is my house so humid is simply the air is nearly or fully saturated.

RISKS OF TOO MUCH HUMIDITY

When the humidity is high indoors, your home runs into certain risks including poor air quality. High indoor humidity often causes:

  • Mold and mildew growth
  • The right environment for dust mites to multiply
  • Insects and rodents seeking moisture. They leave behind droppings, nesting material and other particulates in your ventilation.
  • Cupping in hardwood floors and warping of wooden doors, door frames, and more
  • Uncomfortable living conditions for those with certain respiratory or cardiac conditions.

Humidity increases breathing difficulties for people with asthma, COPD, congestive heart failure and other conditions. Excess humidity increases allergy and asthma triggers like dust mites and mold and mildew spores.

HOW HUMIDITY AFFECTS COOLING

Too much moisture in the air traps heat and makes it feel hotter than the actual temperature. Therefore, it’s important to invest in an air conditioner or heat pump to both cool and dehumidify your home. Michigan weather might be great for growing blueberries, but if it’s humid inside, it may be hard to be comfortable and sleep well.

Humans cool their bodies by sweating. However, if there’s a lot of water vapor in the air, sweat can’t easily evaporate off our skin. At 100 percent relative humidity, for example, sweat won’t evaporate at all because the air is already completely saturated with water vapor.

Many people have ceiling fans to cool their homes, however, it is important to understand that fans do nothing to cool the air. They, in fact, provide a breeze to help your perspiration evaporate easier. They don’t cool the air, they help you feel cooler.

HOW AIR CONDITIONERS COOL YOUR HOME

Your air conditioning unit does more than just blow cold air into your home. It extracts heat and water vapor from the air to meet the temperature set by the thermostat. Inside your air conditioning unit are coils filled with refrigerant.

Refrigerant is a substance which moves back and forth between liquid and gas states to absorb and release heat. As the hot humid air from inside your home passes over these coils, the liquid refrigerant absorbs the heat and turns it into a gas.

To keep your home at a cool temperature, the air conditioner compresses the air inside the coils until it returns to liquid. The extra heat generated by compressing this gas releases outside the home via condenser coils and a second fan.

HOW AIR CONDITIONERS REDUCE HUMIDITY

High humidity makes the inside of your home feel clammy. Fortunately, an air conditioning unit extracts moisture with an evaporator coil. As humid air passes over the evaporator coil, it condenses and drains into a condensate pan.

To avoid water damage, keep an eye on your condensate pan. If you find water around your indoor air handler or suspect a clog in the line, call A-1 Mechanical for assistance. A small amount of water can easily create thousands of dollars of damage.
