How to Choose the Right Air Purifier for Your Home

June 4th, 2021
Air Purifier

Isn’t it awful when one member of your family has a cold, and then the next thing you know, everyone in your house is sick? Improving the indoor air quality in your home with a whole home air purifier can make a big difference in your family’s health. But how do you choose an air purifier that’s right for you? Luckily, the heating and cooling experts at A-1 Mechanical offer two fantastic whole-house air cleaning solutions, and we’ll help you find out which one will be the most effective in your home.

Why Do I Need a Whole House Air Purifier?

The best way to fill your house with clean air is to open the windows and allow the outdoor air to enter and cycle around your house. This may be difficult to do in colder months, though, or if anyone in your family has seasonal outdoor allergies. According to the Environmental Protection Agency, Americans spend almost 90% of their time indoors, which exposes them to 2-5 times the pollutants than they would be exposed to outdoors.

Air cleaners, air purifiers, and air filtration systems all essentially do the same thing; they filter out the contaminants in the air. A lot of these contaminants are living in your vents and HVAC system. When air passes through your HVAC system, it will pass through your new air cleaner’s filter, which strips the air of certain contaminants before it comes out of the registers and into your living areas.

How to Choose an Air Purifier

A-1 Mechanical offers two excellent options to purify the air in your home. You might notice that one is called an “air purifier” and one is an “air filter.” You may be wondering what the difference is between the two types.

The main difference is the type of filter they offer. Air cleaners use fiberglass and activated carbon to filter the air, while air purifiers use a more intense filter with negative ions to sanitize the air. The strength of the filters determines what kind of germs can be caught in them. A filter’s strength is measured in Maximum Efficiency Reporting Values, or MERV rating. This rating is between 1-20. The higher the MERV rating, the better it is.

Infinity Air Purifier

The infinity air purifier is a top-of-the-line product for superior indoor air quality. It has been proven effective against human influenza, common cold germs, and streptococcus pyogenes.

These filters have a 15 MERV rating and can remove common household pollutants from the air such as smoke, odors, dust, and pet dander. They are compatible with most home’s HVAC systems and come with a one-year parts warranty.

Comfort EZ Flex Cabinet Air Filter

The Comfort EZ Flex Cabinet Air Filter is what some might call an “air cleaner.” Although effective in removing very small particles, air cleaners fall short at sanitizing the air. They remove allergens and dust from circulating in your HVAC system but are not great at removing bacteria, viruses, and pathogens that make us sick.

If members of your family suffer from asthma or intense allergies, this is a great choice for you. With a MERV rating of 10, this filter removes up to 65% of airborne particles.

Which Air Purifier Should I Choose?

Choosing an air purifier can seem like a difficult task. You need to ask yourself: which particles bother you and your family the most? If your family seems constantly sick, or someone in your home has COVID-19, the Infinity Air Purifier is probably the best choice for you to stop the spread of germs. This might also be a good choice if you have pets.

If your family suffers from seasonal allergies or asthma but is otherwise healthy, the Comfort EZ Flex Cabinet Air Filter would be a great match for your family.

Call A-1 Mechanical to Start Breathing Easy

If you’re buying an air purifier, the best way to be sure you choose the best model for your home is to talk to one of A-1 Mechanical’s indoor air quality experts. They’ll assess your needs and help you solidify your choice of air cleaning solutions. Call us today to learn more.

Why Is My Heat Pump Not Keeping Up?

May 21st, 2021
Heating

Contrary to what the name might suggest, heat pumps can be used to both heat and cool a home. When your heat pump isn’t keeping up with your demands when you need it most, however, there can be a number of issues at play. Keep reading to discover what might be keeping your heat pump from reaching your set temperature, and what you should do when that happens.

What Can Keep a Heat Pump From Reaching a Set Temperature?

Unit is Iced Over

Setting your thermostat below 70°F can cause your heat pump system to frost or even completely freeze up. When this happens, your unit won’t run as efficiently and will likely have trouble reaching a set temperature.

Additionally, your system can be prone to more issues if you continue to use it while it’s iced over. The fan blades on your system, for example, can break, or refrigerant may leak within the outdoor unit.

System Isn’t Running

If your system is having trouble just turning on, it likely won’t be able to consistently reach the temperatures you’re setting. This could quickly turn into an emergency, especially during extremely hot or cold weather, so it’s important to call on a professional heating, air conditioning and indoor air quality technician immediately after noticing that your heat pump unit is not turning on.

A professional can diagnose the issue and recommend the best course of action, whether it’s heat pump repair or replacement services.

Vents in the Home are Closed

If some rooms feel as though they’re at the temperature you’ve set and other rooms feel significantly warmer or cooler, the issue could be as simple as having vents in your rooms that are closed. Ensure that all rooms in the home have open vents before reaching out to a professional about having your unit inspected.

Allowing the air to circulate and flow freely can do wonders in helping your home reach the temperature that you’ve set.

What are Some Common Heat Pump Problems?

Lack of Power

The risk of having a heat pump is that they’re fully electric, which can cause issues in the event that your home’s power supply goes out. If your heat pump isn’t turning on but you haven’t recently suffered a power outage, ensure that the circuit breaker hasn’t been tripped.

A lack of power to your heat pump for too long can cause the evaporator coil to freeze and not work when the AC turns back on. If the system hasn’t had power for over half an hour, get in touch with a professional to learn about the best way to turn the system back on to ensure you don’t experience any issues.

Unreliable Thermostat

Sometimes, a heat pump that doesn’t reach the set temperature can be the fault of your thermostat, rather than the heat pump itself. If you’ve had your heat pump inspected and everything appears to be normal, have your thermostat checked. The unit could be calibrated incorrectly and not communicating with the heat pump.

Reversing Valve is Broken

The reversing valve within your heat pump is the part that allows the unit to be used for both heating and cooling. When this valve is broken, it can cause inefficient heating and cooling and should be fixed immediately.

A-1 Mechanical Solves Heat Pump Issues

Heat pumps are complex systems that can often be confusing. When your heat pump experiences any issues that cause it to not work as efficiently as it once did, you should get in touch with an HVAC professional. Doing so will ensure that the issue is fixed properly to give your family enhanced comfort and safety all year long.

The experts at A-1 Mechanical know that you can’t afford to be without proper heating and cooling during the coldest and hottest of days. If your heat pump isn’t working properly and experiences any of the issues above, or any not on that list, don’t hesitate to get in touch with us.

How Do Air Purifiers Improve Health?

May 21st, 2021
Air Purifier

While you can’t see bacteria and viruses that lead to sickness traveling in your air, those contaminants are very likely still present. However, there are ways that you can fight back and improve your home’s indoor air quality.

We all want to protect our families in any way possible. Air purifiers can help your family stay safe and healthy from bacteria, viruses, and other indoor air pollution that might be traveling in your indoor air supply. Keep reading to learn more about how air purifiers work, as well as how they can be used to improve your family’s health and reduce allergy and asthma symptoms.

How Do Air Purifiers Work?

You’re probably familiar with how air filters work. Air filters work by removing any harmful indoor particles from the air. Air purifiers, on the other hand, go a step beyond. They remove air pollutants and harmful particles in the air and then sanitize the air supply to add an extra layer of protection.

Because air purifiers actually sanitize the air that your family breathes, most homes find them to be far more effective than air filtration systems.

How Air Purifiers Can Improve Your Health

Many common airborne diseases are contracted through small pathogens that might be traveling through your air. That’s why common colds and flus are able to spread so quickly between family members.

An air purification system catches and removes these pathogens and volatile organic compounds and then sanitizes the air to completely eliminate any traces of dangerous pathogens and particles.

These systems are a great way to improve the overall health of those within your home, but it’s important to note that they won’t completely eliminate all particles. Dangerous particles that can cause sickness can still live on surfaces such as tables, walls, and carpeting.

How Air Purifiers Reduce Allergy and Asthma Symptoms

Common irritants and allergens such as dust, mold, and bacteria can wreak havoc on anybody who suffers from common allergies or asthma. Breathing in particles from these pollutants can make anyone feel miserable throughout the day.

However, air purifiers and air cleaners can help by eliminating these allergens and decreasing mold growth. Save yourself and your family from the constant sneezing and coughing caused by allergy symptoms with the installation of an air purification system.

Get in touch with us today for more information about how air purifiers can provide health benefits by reducing and even eliminating allergy and asthma symptoms.

Can Air Purifiers Improve Sleep?

Thanks to the elimination of irritating and potentially harmful indoor air pollutants by an air purifier, you’ll feel better and get sick less. You’ll be breathing easier, allowing you and your family to fall asleep faster and stay asleep longer.

With better sleep from your air purifier comes benefits such as a better immune system and improved cognitive abilities. An air purification system can help your family stay safe, healthy, and happy.

Contact A-1 Mechanical for Air Purifier Services

The experts at A-1 Mechanical want to help your family stay safe, healthy, and comfortable all year long. If anybody within your house is dealing with allergies or asthma symptoms, or you’ve had more illnesses than normal running through your family, get in contact with us today to schedule an appointment for air purifier installation or other indoor air quality services. We’ll help you breathe healthier, more comfortable air than ever before.

Signs You Need a New Air Conditioner

May 21st, 2021
Air Conditioning

With proper maintenance, an air conditioning system typically lasts around 15 years. When you experience frequent repairs or outages, however, you may need to install a new AC before then. In addition to frequent repairs and outages, there are other signs you need a new air conditioner. Read on to learn more about the signs your air conditioner needs to be replaced and how to prevent an outage during the hottest months of the year.

Common Signs It’s Time to Replace Your AC

Your air conditioner needs replaced if it’s showing any of the following warning signs:

  1. Your air conditioner is more than 15 years old
  2. Low energy efficiency
  3. Frequent repairs
  4. High indoor humidity

We’ll cover them in more detail below.

1.) Your Air Conditioner is More Than 15 Years Old

When properly maintained, air conditioners typically last around 15 years. If you are unsure of the age of your AC unit, schedule a maintenance check, and ask your technician. When your AC unit is roughly 12 years old, start planning for a replacement.

Professional HVAC contractors run through a rough cost and benefit analysis with you when your AC unit is 12 to 15 years old. If you find a major repair earlier and could upgrade to a more efficient model, consider it.

The difference in energy efficiency and the cost to operate often negates the replacement cost. This way you have the information you need to decide whether continued repairs or a new unit is best for your family’s financial plan.

Your HVAC contractor easily determines the best AC unit and style for your home and lifestyle.

2.) Low Energy Efficiency

If your energy bills seem unusually high during the warmer months, the culprit is probably an inefficient air conditioner. This is another sign you may want to replace your air conditioner.

SEER (Seasonal Energy Efficiency Ratio) ratings measure the energy efficiency of an air conditioner. The higher the SEER rating, the less energy your air conditioner uses to cool your home. AC units on the market have at least a 13 SEER. However, if you have an older air conditioner in your home, the SEER rating is potentially 6 or less.

New ENERGY STAR air conditioners are beneficial to your wallet, as well as better for the environment. Whether you upgrade to save on energy costs, or to improve your environmental impact, a new AC unit lowers your monthly energy bill.

3.) Frequent Air Conditioner Repairs

Frequent cooling system repairs and service calls are signs that you need a new air conditioner. They potentially cost more in the end than a new system. A new air conditioning system saves you money on pricey repairs, as well as energy bills, if you install a more efficient system.

A good HVAC system technician provides a full picture of your current air conditioner costs as well as the costs associated with a new system. You might be surprised how much you save with a new air conditioner versus patching up your old one.

4.) High Humidity

Air conditioners remove humidity from the air as part of the cooling process. If your home’s air feels uncomfortable, the excess humidity is often to blame.

When the air conditioner cycles but does not seem to remove your home’s humidity, it is time for a check. A trained heating and cooling technician tests the humidity in your home and diagnoses any problems with your air conditioner.

Is It Safe to Leave Your Home’s Air Conditioner On if You’re Not Home?

April 30th, 2021
Air Conditioning

As the weather steadily gets warmer, homes across Michigan will start using their air conditioners again. While air conditioners are a great way to cool down and keep you comfortable during the hotter months, many homeowners remain unsure of what they should do with the AC when they’re away from home, especially for longer periods of time. Is it best to keep it running as normal, have it run at a higher temperature, or shut the system off completely?

In our most recent blog, the technicians at A-1 Mechanical answer these important questions.

Why You Might Want to Turn Your AC Unit Off

If you’ll be away from home for days or even weeks for work or vacation, you’re likely considering turning your AC off. Most commonly, homeowners might turn their air conditioner off in an effort to save money on energy costs.

The team at A-1 Mechanical absolutely understands your desire to save on your energy bills. If nobody will be home to enjoy the comfort provided by your air conditioner, it might at first seem to make sense to turn the system off altogether. However, it’s safer to keep your air conditioner on when you’re not home.

Benefits of Keeping Your AC Unit Turned On

You’re likely aware that your home’s air conditioner does more than just keep your home at a nice, comfortable temperature. It also dehumidifies your home’s air supply. Without a running air conditioner, homes in warmer and more humid climates can experience mold and fungi growth, among other issues caused by high humidity.

Keeping your air conditioner turned on when you’re not home will allow the indoor air supply to be dehumidified, lowering the likelihood of any mold developing while you’re away. For this reason, it’s safer to leave your air conditioner on. However, that’s not to say there aren’t ways to save on your energy bills when you’re not at home for an extended period of time.

How to Save On Your Energy Bill When You’re Not Home

While you shouldn’t choose to turn the cooling system off entirely, adjustments can be made to the system to ensure that you’re still saving on your energy bills. For example, setting the temperature about 7 to 10 degrees higher than normal will cause the air conditioner to run less frequently. You’ll save on energy, while still allowing your AC to stay on and remove excess humidity.

If your home has a programmable or smart thermostat, there’s even more reason to turn the thermostat up before leaving! Depending on your specific model, you can program your thermostat to stay at the higher temperature while you’re gone and have it automatically lower the temperature just prior to returning. This increases energy savings and allows you to return to a home that is instantly cool and comfortable.

Different Types of Heating Systems and the Advantages of Each

March 26th, 2021
Heating

Did you know that you have options when it comes to heating your home? You don’t have to stay with the gas-powered furnace. If you’re building a new home, or it’s time to replace your heating system, now is a great opportunity to research Different Types of Home Heating Systems. There are pros and cons to all three, but you can trust the experts at A-1 Mechanical to fix any problems you have when it comes to repairs.

What Are the Different Types of Home Heating Systems?

Keeping your home comfortable during cold winter months is essential in Lansing and Grand Rapids. You want a heating system that you can rely on year after year. A-1 Mechanical breaks down the three different types of home heating systems and the advantages of each.

Furnaces

Furnaces use gas to generate heat by combusting fuel. This ensures that you’ll always have heat in your house no matter the temperature outside. The furnace controls the temperature in the entire house with a thermostat. Most furnaces can last anywhere between 15 to 20 years with proper maintenance.

Advantages of a Furnace
Although furnaces are larger than heat pumps, they are less noisy. Furnaces are a more reliable source of heat in colder climates. You are also probably familiar with how a central heating system operates since it’s been a reliable heating source for homes for decades. Newer models improve on efficiency, making sure your heating bills aren’t extravagant.

Heat Pumps

Air source heat pumps are another popular type of forced-air heating system. Air-source heat pumps can perform both the functions of a furnace and an air conditioner, providing cool and warm air inside. Heat pumps are relatively small and can be mounted outside your home. When connected with mini splits, your house can be divided into different zones. These zones can accommodate different levels of comfort among your family members. If you have a large house, or want to create multiple zones, you may need more than one heat pump.

Advantages of a Heat Pump
Heat pumps are very energy efficient. They use much less energy than a furnace, making them less expensive to operate. Since they also operate as an air conditioner, you may save on cooling costs as well. Heat pumps are also cheaper to install than a furnace.

Geothermal Heating

Geothermal heating is the most energy efficient type of heating system. Pipes are inserted into the ground and the heat from the Earth is transferred into your home. This air can be heated or cooled, depending on the season. In order for a heat pump to work, a system of interconnected pipes used as heat exchangers are placed underground. To have the pipes installed, you’ll need holes dug in your yard which could affect your landscaping. Geothermal heat pumps can come with a lot of upfront costs. It is usually the most expensive heating system to install, but government tax rebates can help offset the cost.

Advantages of Geothermal Heating
Geothermal heating is warmer than the air provided by heat pumps, but not as warm as a traditional furnace. However, there is still enough heat to keep your home more comfortable, making it the most efficient-heating system. The lifespan of geothermal heating is 20+ years, much longer than a furnace or heat pump.

Trust A-1 Mechanical for All of Your Heating Needs

When it comes to choosing a heating system that works best for you, trust the pros at A-1 Mechanical to assess your home’s heating needs. We provide options at various price points and can provide estimates for installation. Call A-1 Mechanical today to learn more about our heating systems. Our heating and cooling technicians can repair, maintain, and install all types of heating and air conditioning systems.

Why Is My Furnace Flue Pipe Rusting?

March 26th, 2021
Furnace

When you look at your furnace, you’ll notice a large pipe sticking out of it that leads into a wall or ceiling. From the outside of your house, you may notice a pipe sticking out of your roof. Both of these pipes are your furnace flue pipes. They exhaust water vapor, carbon monoxide, and other gasses from your home. These pipes are essential for keeping the air flowing in your home and making sure toxic gases do not harm you or your family. If you notice that either one of your Furnace Flue Pipes Rusting, this could be a sign of worse problems to come.

A-1 Mechanical Heating & Cooling is your furnace and heating specialist. Repairing or replacing a furnace flue pipe could involve climbing on your roof or getting dirty. It’s best to trust the professionals to inspect your furnace as well when you notice any sort of rust in your HVAC system.

Why is My Furnace’s Flue Pipe Rusting?

There are a few reasons your furnace’s flue pipes are rusting. Ideally, combustion within a furnace would have two side effects: water vapor and carbon dioxide. However, no furnace is 100% efficient, and in every furnace some portion of the gas fails to combust entirely. This partial combustion results in the creation of byproducts like carbon monoxide and other toxic gasses. These gases are pushed through the furnace flue pipes and exhausted from the home.

When your furnace isn’t burning gas as efficiently as it could, there may be more byproducts being created in your furnace than you realize. These byproducts have chemical reactions with your exhaust pipes, causing them to rust.

Another reason why your furnace flue pipes are rusting is because there is an imbalance in the air to fuel mixture in your furnace. This could happen if you have a new furnace that is not compatible with your flue pipes, or there is insufficient pressure differential causing gases to have difficulty leaving your home. Rusty furnace flue pipes might just need to be replaced, or they could be a telling sign about the performance of your furnace.

I Have Rusty Furnace Flue Pipes

Furnace flue pipes aren’t always easy to see. If you’ve noticed strange odors in your house when your heat is on, or lack of airflow in your house, it’s best to inspect your furnace flue pipes. One should be attached from the furnace to the wall. Another might be on your roof. If you find rust on either, they could be a sign of issues that should be addressed immediately.

Rusted furnace flue pipes are more common in older homes and could be a sign of an aging HVAC system. If you had a new furnace installed recently, your pre-existing flue pipes might not be compatible with your new system. The best thing to do is to replace your pipes right away. Luckily, this is a relatively inexpensive fix, and it can prevent a dangerous situation in the future.

What If I Don’t Replace My Rusty Furnace Flue Pipes?

Think about rust on a car. You can slow down the growth of additional rust, but you can’t make the rust go away. It will get worse and corrode parts of your car. The same thing can happen with rusty pipes. Not only is rust unsightly, it can corrode and prevent toxic gases from leaving your house.

If toxic gases like carbon monoxide leak into your house, the results could be deadly. This is why you shouldn’t put off replacing rusty pipes. To prevent rusting in your HVAC system, it’s important to have it regularly cleaned and inspected to keep it running efficiently and safely.

What is the Average Life Expectancy of a Gas Furnace?

February 11th, 2021
Gas Furnace

Whether you’re in the market for a new furnace or have concerns about your existing unit, there is one question we hear often from Grand Rapids area homeowners – how long does a gas furnace last? A-1 Mechanical explains how long these furnaces typically last, what you can do to get the most life out of your gas furnace, and how to spot signs of impending system failure. For all of your home’s heating system needs, contact us today.

How Long Does a Gas Furnace Last?

The service life of your furnace depends on different factors such as type, use, and care – no two furnaces or heating systems are exactly the same.

Residential gas furnaces typically last about 15 years. This estimate is just an average, though, as the life expectancy of a residential gas furnace depends most on the way you use it and how you take care of it, year after year.

Improving Gas Furnace Service Life

Getting the most years of service from your gas furnace starts at installation. Whether the system was sized appropriately for the space and installed correctly greatly affects its average lifespan. A furnace that is too big or too small for the home must work harder to keep the indoor living areas comfortable, either by running for longer periods or short cycling as heat is rapidly added to the space. Incorrectly sized furnaces experience faster wear and tear which causes breakdowns and takes the system out of service prematurely.

When installing a new furnace in your Grand Rapids home, work with a licensed heating professional who will properly determine the correct equipment size for your space. Consider hiring an HVAC contractor who employs NATE-certified technicians who are known to deliver superior installation services for new furnace equipment.

After your furnace is installed, you’ll need to have it regularly maintained to keep it running in optimal condition year after year. Here in Michigan, furnaces typically run most of the winter. If you like to keep your home’s temperature in the 70s, your furnace will run more often than if you kept the temperature in the high 60s. Heavy use speeds up wear and tear, and you may require furnace replacement sooner than if the system was not used as frequently. As you use your furnace each winter, consider lowering your thermostat to keep heating costs low and to help boost the unit’s average lifespan.

Lastly, the life expectancy of a gas furnace is most greatly impacted by the maintenance it receives over its years of service. Gas furnaces require professional maintenance tune ups each year to preserve system efficiency, counteract wear and tear, and prevent damage as best as possible. A neglected furnace will typically require replacement sooner than one that received its annual tune ups each year. Protect your investment by making regular maintenance a priority. A-1 Mechanical offers furnace maintenance plans to make this care as easy as possible!

Warning Signs It’s Time for a New Furnace

Sometimes it’s hard to know when you need furnace replacement. Watch out for these warning signs that indicate your furnace is on its last leg:

  • If your gas furnace is between 15 to 20 years old, replacement could be needed at any time so it’s best to start preparing when your system reaches this age range.
  • If your energy bills have steadily risen over the past few winters without a clear explanation, the declining efficiency of your furnace is likely to blame.
  • If your furnace is having a hard time keeping your living areas supplied with ample heating, a new furnace may be the solution to your comfort problems.
  • Furnaces usually see more breakdowns in their final two years of service – if you’ve been calling us more often for furnace repairs the last few winters, it’s likely time to replace your furnace.

How Does Geothermal Heating Work? A Step-By-Step Guide

February 11th, 2021
Geothermal Heating

Geothermal heating and cooling systems provide the most energy-efficient means to control temperatures inside Grand Rapids homes and businesses. While it’s not a new technology, many people have either not heard of it or aren’t aware of how it works. In our most recent blog, the HVAC technicians at A-1 Mechanical discuss how geothermal heat pumps work and their benefits to help you better understand this amazing HVAC technology!

Parts of a Geothermal Heating & Cooling System

Our step-by-step guide on geothermal heating and cooling systems begins with an explanation of how these systems’ components work. Geothermal systems consist of three main parts: a ground loop, a heat pump, and a distribution system.

  • The ground loop is a piping system that is buried on the property. It is either a closed loop or an open loop, which opens into a water source nearby, such as a pond or well. These underground pipes are filled with fluid that assists in heat exchange.
  • The geothermal heat pump exchanges heat between the air and the ground loop system, extracting heat from the air or the ground loop depending on whether heating or cooling is in use.
  • The distribution system is the method which delivers heated or cooled air throughout the home. Forced air geothermal HVAC systems use ductwork to deliver conditioned air inside, just like a conventional furnace or air conditioning system. Some geothermal heating and cooling systems may be configured with hydronic distribution, a network of fluid-filled piping that runs throughout the home to carry heat energy. The heat pump’s heat exchanger exchanges heat between the fluid in these pipes and the fluid within the ground loop instead of between the air and ground loop fluid.


How Does a Geothermal Heat Pump Work?

A geothermal system works by exchanging heat between the air and the ground. Because temperatures below ground remain consistent around 55 degrees Fahrenheit all year, there is always significant energy available to heat your home – and it’s free energy! Here’s a step-by-step explanation of how ground source heat pumps provide heat for your home:

  1. Fluid within the ground loop absorbs heat from the surrounding earth.
  2. This fluid is pumped through the ground loop up to the heat pump, which is housed inside the home.
  3. The heat pump’s heat exchanger uses the energy to warm the air that passes through the unit.
  4. The heated air circulates through the ductwork into indoor areas throughout the home or building.

Ground source heat pumps are great because they also provide indoor cooling! Here’s how a geothermal system works for cooling:

  1. The heat pump’s heat exchanger extracts heat from the air circulating through the system.
  2. The heat pump transfers this heat to the fluid within the system.
  3. The fluid is pumped down through the ground loop, carrying heat.
  4. Heat from the fluid is deposited into the earth or water source that serves as the system’s heat sink, or receptacle for heat energy.

Why Won’t My Furnace Turn On?

December 16th, 2020
Furnace

One of the biggest issues Grand Rapids area homeowners face during the winter is a broken-down furnace. Several issues can cause a furnace failure – some may be quickly solved through troubleshooting, while others require professional repairs. When you’re faced with a furnace that won’t turn on, here are the most common reasons why and what to do about them.

1. Wrong Thermostat Settings

The first thing to do is check your thermostat to see if it’s operating or set correctly. Your thermostat is the controller of your furnace’s operation, signaling it to fire up when indoor air is too cold and shut down once proper indoor temperatures are reached. If the thermostat isn’t set correctly, it won’t communicate properly with your furnace, resulting in furnace problems, including a unit that won’t turn on when it’s expected to.

  • Check the thermostat to make sure it’s set to HEAT.
  • The set temperature should be higher than the current room temperature.

2. No Power

All components of the heating system need to have power for the furnace to work. If there’s not a power outage affecting your home, check individual switches and power sources to ensure every system component is properly powered.

  • If the thermostat has a blank display or you cannot adjust it, the unit’s batteries may be dead. Replace them with a fresh set. If the thermostat is hardwired, check the circuit breaker that controls its circuit. If the breaker has tripped, reset it to restore power to the thermostat.
  • Check the circuit breakers that deliver electricity to the furnace. If the circuit breakers have tripped, reset them.
  • Check the on/off switch located on or near your furnace, and make sure it is set to the ON position.
  • If you own a natural gas furnace, make sure the gas valve is open to let the system receive fuel.
  • For oil or liquid propane furnaces, check your fuel tank to verify there is enough fuel for heating system operation. For oil tanks, keep the fuel volume above four inches; for liquid propane tanks, order a tank refill before the tank volume dips below 25 percent.

3. Pilot Light Is Out

While modern furnaces use electronic ignition, some older furnaces still use pilot lights. If the pilot light goes out due to a draft or system issue, you’ll have a furnace that won’t be able to create heat.

  • Find the pilot light assembly, which is usually located toward the furnace’s bottom. See if your furnace flame is burning or if it is out.
  • If the pilot light is out, you’ll need to relight it. First, stop any drafts that could’ve caused the pilot to extinguish. Turn the pilot switch off for at least five minutes to allow any gas to dissipate.
  • When ready, follow the instructions in your furnace’s owner’s manual to relight the pilot.
  • Once the pilot is relit, watch to see that it burns a strong blue flame and does not extinguish again. If it does go out, there could be an issue with a thermocouple. If the flame is weak and yellow, there could be dirt or other debris clogging the air intake. Call your HVAC technician to assess and repair the system.

4. Dirty Air Filter

Dirty filters can cause heating systems to overheat because they restrict air flow. If this occurs, you’ll notice that your furnace isn’t turning on – the system’s safety controls shut down operation to allow the equipment to cool.

  • Remove the faulty or dirty filter, and replace it with a new one. Be sure to use the same size air filter, and insert it into the filter cabinet in the proper direction.
  • Check filters monthly during the winter and change them as needed – it’s often necessary to replace filters more frequently this time of year because of increased heating use.

5. Blower Motor Issue

If the blower motor malfunctions, your forced air furnace may run but your home will not receive any heat. Inspect the blower to see if the issue can be resolved. You may need to contact a qualified HVAC company for repair services.

  • Shut off power to the furnace, and remove the access panel to the blower chamber. Check for any debris that may be blocking the fan blades or heavy dirt that could be clogging up the motor. Clean as necessary.
  • Check the belt linking the motor and fan. If it has slipped or become loose, you may be able to tighten and reposition it. If the belt has broken, it needs to be replaced.
  • If you cannot find the blower motor issue, it’s time to call for professional furnace repair.
