No matter what your budget, we have ductless solutions that will improve comfort in one area or across your entire home.

Benefits of Ductless Mini Split Installation

Carrier ductless HVAC systems differ from the conventional forced air furnaces and central air conditioning systems many homeowners are used to. Instead of using a central indoor unit and ducts to deliver conditioned air across the home, ductless mini splits have dedicated air handling units that are installed in each zone of the home. No ducts are needed as heated or cooled air is sent directly into the targeted space by each unit.

Installing a ductless mini split system, including Carrier ductless HVAC systems, can bring many advantages to Michigan homeowners. Some of the benefits you’ll enjoy from a ductless mini split HVAC system include:

  • Zoned comfort. With individual air handlers installed in specific areas of the home, heating and cooling in each space can be controlled independently of all other rooms. These systems give homeowners and their families the ability to set temperatures to everyone’s unique preferences, without affecting comfort levels across the entire home.
  • Energy savings. Thanks to their supreme energy efficiency and the advantages of zoned comfort, Carrier ductless heating and cooling systems help homeowners save on energy bills compared to using ducted conventional HVAC equipment. Seeing as most homes have 20 to 30 percent energy loss through duct leaks, there’s an immediate savings when you go ductless! When replacing a forced air HVAC system, expect to save between 30 to 40 percent on your energy costs.
  • Easy installation and versatility. One ductless heat pump unit can support multiple indoor air handlers, giving homeowners the flexibility to add efficient heating and cooling in specific areas or throughout the house. Without the need for ducts, Carrier ductless heating and cooling systems can be installed rather quickly. Air handling units are connected to the outdoor heat pump via a line set that runs through an exterior wall, requiring a hole only about 3 inches in diameter.
  • Better indoor air quality. By eliminating air circulation through dusty, dirty ductwork, Carrier ductless heating and cooling systems can deliver better indoor air quality versus ducted systems. Air handlers have dedicated filters that require minimal routine maintenance to preserve air quality and performance.

Is There a Geothermal Tax Credit Available for HVAC Systems?

October 14th, 2021
Tax Credits & Rebates

Over the past several years, you may have heard talk about federal tax credits for homeowners who make certain home improvements, such as installing new high-efficiency HVAC equipment. Currently, there is a geothermal tax credit available to Lansing and Grand Rapids area homeowners who install new geothermal heat pump systems that meet certain requirements. A-1 Mechanical shares the details of this credit and why a geothermal system is a great investment for your household.

About the Geothermal Tax Credit

Thanks to the Consolidated Appropriations Act of 2021, there are various renewable energy tax credits available to homeowners across the country. Homeowners can gain this tax savings by installing approved fuel cells, small wind turbines, solar energy systems, or geothermal heat pumps.

Under the current federal geothermal tax credit, homeowners can claim a federal tax credit of 26% of total installation costs for geothermal heat pump systems placed into service before January 1, 2023. This credit is retroactive for all qualifying systems installed starting January 1, 2020 – so if you recently installed a geothermal system at your home, check to see if you qualify for this savings. Starting January 1, 2023, the tax credit amount will drop to 22%, so if you’re considering a new geothermal system, you’ll save more if you install one sooner rather than later.

The geothermal tax credit can be claimed for systems installed at a secondary residence, as it is not required that the credit only be claimed for systems installed at a primary home. In order for a system to meet the requirements for homeowners to claim the geothermal tax credit, the geothermal heat pump installed must meet ENERGY STAR requirements as of the date of the expenditure.

Currently, the specifications for a qualifying geothermal heat pump’s EER (energy efficient ratio) and COP (coefficient of performance) are:

  • Greater than 17.1 EER and 3.6 COP for water to air closed loop systems
  • Greater than 21.1 EER and 4.1 COP for water to air open loop systems
  • Greater than 16.1 EER and 3.1 COP for water to water closed loop systems
  • Greater than 20.1 EER and 3.5 COP for water to water closed loop systems
  • Greater than 16 EER and 3.6 COP for direct expansion systems


Benefits of Installing a Geothermal System

Geothermal systems are a type of HVAC system that provides both heating and cooling using natural energy held within the earth. These systems are extremely energy efficient and come with unmatched benefits including:

  • Extremely long service life. Geothermal heat pumps last about 20 years or more on average, and underground loop components last 50 or more years!
  • Geothermal heating and cooling equipment makes very little noise while operating so you’re not disturbed by your HVAC system.
  • Heat pumps used in geothermal systems have few moving parts, requiring less maintenance and experiencing fewer breakdowns than other types of HVAC equipment.
  • Geothermal systems exchange heat to warm or cool your home, so they use far less electricity than other types of HVAC systems. Using a geothermal system could cut your cooling bills 20 to 50%, and lower your heating bills 30 to 60%!

Common Heat Pump Problems and How to Fix Them

September 20th, 2021
Heat Pump

As fall arrives, heat pump HVAC systems will start to switch gears, giving the cooling cycle a rest as these units are called upon for heating. Over the cooler months, you may experience heat pump problems that can stand in the way of perfect heating for your home. A-1 Mechanical explains how you can troubleshoot some of the most common heat pump problems and get your heating system back up and running again quickly!

Your Heat Pump Is Blowing Cold Air

Heat pumps should blow warm air through the vents when they run as a heating system in fall, winter, and early spring. If you feel cool air coming from your vents, here are a few things to check before you call for repairs to fix your heat pump.

  • Make sure the thermostat is set to HEAT, not COOL. If the thermostat is set to COOL mode, the heat pump will run cooling cycles and produce cool air. Settings are sometimes incorrectly changed, causing heat pumps to blow cool air.
  • Check the fan settings on the thermostat as well. The fan should be set to AUTO mode, not ON. If the fan is accidentally set to ON, it will blow cool air into the house during times when the heat pump itself is not actively cycling, causing homeowners to think there’s an issue with their heat pump system.
  • Make sure there is no ice buildup on the outdoor unit. If there is, follow the directions below to melt ice from your unit.
  • The heat pump could be running its defrost cycle when you feel the cool air. The defrost cycle typically runs for about 10 to 15 minutes – wait it out to see if heat returns in the next half hour or so.


Heat Pump Runs All the Time

If it seems like your heat pump is running around the clock, it may seem like there’s an issue to worry about. However, it can be normal for your heat pump to run for long periods – especially if outdoor temperatures are very cold. There are some issues that can contribute to a heat pump running longer than it needs to:

  • Dirty air filters can restrict airflow through the system, forcing your heat pump to run for longer periods to supply the home with enough heating. Check the filter, and replace it with a fresh one if you find the filter is dirty and covered in contaminants.
  • Make sure all of the supply vents and return air registers in your home are opened and unblocked. These vents can be accidentally covered by furniture, rugs, and other items, which restricts airflow through the house and forces the heat pump to run longer periods.
  • Air leaks in ducts, window frames, door jambs, and other problematic areas throughout the house could cause your home to take on excess cool air. This lowers the temperature in your home, forcing the heat pump to run longer periods to make up the warmth you need. Air sealing and duct sealing can eliminate this issue.


Heat Pump Freezes Up

This problem is more common in the winter when outdoor temperatures are chilly. The outdoor heat pump unit may show a layer of frost or ice on its exterior, which is normal and is periodically removed through the system’s defrost cycle. If the defrost cycle isn’t removing this frost or outside conditions prevent the heat pump from shedding ice, the system will not work correctly.

If you find a heavy layer of ice atop your outdoor heat pump, notice the coils are completely encased in frost or ice, or the entire outdoor unit has a layer of ice around it, the system will not work correctly and could sustain damage if the ice is left for too long.

  1. Shut off power to the heat pump at the circuit breaker in the home.
  2. Use a hose to spray the unit with warm water and melt the ice – do not use objects to chip away ice accumulation as that can damage the heat pump system!
  3. If temperatures are above freezing, restore power to the heat pump and run it in fan mode to blow warm air through the unit and help melt any remaining ice.

Frozen heat pump problems occur for various reasons, such as low refrigerant, issues with the defrost cycle, and even water leaking onto the unit from a faulty gutter above. Make sure overhead gutters are flowing properly, and remove any debris from around your unit. Replace the air filter with a clean one if it is dirty. If the heat pump continues to freeze, call your HVAC company for repairs.

What Size Air Conditioner Do I Need?

August 18th, 2021
Air Conditioning

As you shop for a new cooling system, there is one important question you need to ask: “What size air conditioner do I need?” It’s important to get the right fit, or else your comfort and costs will be negatively impacted over the lifespan of your new air conditioner. A-1 Mechanical shares what you need to know about air conditioner sizing and how to find the right unit size for your Grand Rapids area home.

What Does Air Conditioner Size Mean?

Air conditioner sizing doesn’t refer to the physical dimensions of the new unit, but rather its capacity to cool a space. Air conditioner sizes are referred to in tons, but tonnage does not refer to the unit’s weight – tonnage refers to the air conditioner’s capacity to remove heat from the home.

The tonnage of an air conditioning unit describes the amount of heat the system can remove over the course of one hour to cool the home. In the HVAC industry, we use British thermal units (BTUs) to measure heat, and there are 12,000 BTUs of heat per one ton of air conditioning. So, a 2-ton air conditioning unit can remove 24,000 BTUs of heat each hour; a 3-ton air conditioner removes 36,000 BTUs of heat per hour, and so on.

Why It’s Important to Buy the Right Size Air Conditioner

When you find out the right size air conditioner your home needs, it’s important you stick to this size as you purchase your new cooling unit. Air conditioners are not one-size-fits-all, and it’s not wise to size up or down to find a better fit as you can do with clothing and other items. This is because the size of your unit will impact the amount of energy the air conditioner consumes, how it operates, and the comfort levels inside your home.

  • If you buy an air conditioner that is too small for the home, the unit will not have enough capacity to remove the necessary heat from the space in order to keep rooms at comfortable temperatures. The unit will run more often as it attempts to make up for its shortcomings, wasting energy and increasing wear and tear, which causes more breakdowns and repairs as well as earlier system failure.
  • An oversized air conditioner won’t keep your home comfortable, either. With excess capacity, the AC unit will rapidly cool but fail to do so evenly, causing discomfort. This creates cooling cycles that are much too short for the health of the appliance, which strain the equipment, add wear and tear, and take the system out of service sooner than a correctly sized air conditioner. They will also not run long enough to remove humidity from the air.


What Size Air Conditioner Do I Need?

The best way to find out what size air conditioner your home needs is to work with a qualified HVAC technician. Many components play a role in determining the right size AC unit for a home – it’s not just about square footage. Various elements, to name a few, that impact the home’s cooling load (how much heat needs to be removed) include:

  • Square footage
  • Number of stories
  • Ceiling heights
  • Number of windows and doors
  • Insulation levels
  • Building materials
  • Number of occupants
  • Home’s orientation


These elements are factored in as a professional HVAC technician performs a Manual J load calculation, which provides the home’s cooling load. This calculation indicates how many BTUs of heat need to be removed from the space over the course of an hour, so you’ll know the appropriate capacity in tons for your new air conditioner.

Find the Right Air Conditioner for Your Grand Rapids or Lansing Home

If you’re in the market to buy a new central air conditioner, it’s time to call A-1 Mechanical. Our qualified HVAC technicians will determine the right size unit for efficient performance and reliable comfort in your home, and provide skilled installation so your new cooling system performs as expected.

What Are the Advantages of Enrolling in an HVAC Maintenance Plan?

August 18th, 2021
Maintenance Plan

Homeowners tackle maintenance tasks throughout the year to protect their homes, keep their residences looking good, and to make their loved ones as comfortable as possible. Heating and cooling systems like furnaces, air conditioners, heat pumps, boilers, and other units require regular maintenance, but too often, homeowners overlook this critical service. Find out how you can simplify the upkeep of your home and gain value with an HVAC maintenance plan.

What Is HVAC Maintenance, and Why Is It Needed?

HVAC systems need to be maintained each year by a reputable heating and air conditioning professional. Professional maintenance is a service that inspects, tests, and services critical components of the HVAC system. Professional maintenance is necessary for numerous reasons, including:

  • Improves system performance
  • Increases energy efficiency
  • Reduces wear and tear
  • Minimizes system breakdowns
  • Extends system service life
  • Maintains warranty coverage


A professional tune up should be in addition to simple maintenance you perform between service visits, not in place of it – you still need to change your air filter regularly and correct airflow blockages, along with other routine tasks. Heating systems like furnaces and boilers as well as air conditioners require one annual tune up. Heat pump systems that provide both heating and air conditioning for the home should be tuned up twice per year.

What Is an HVAC Maintenance Plan?

It’s easy to forget to schedule heating and cooling maintenance tune ups throughout the year. Many homeowners don’t pay much mind to HVAC equipment unless it’s causing issues – they are largely out of sight and out of mind. However, skipping this important service can have serious negative consequences when it comes to the condition of your equipment, the comfort of your home, and even your manufacturer’s warranty coverage.

To help homeowners stay on top of their home heating and cooling system maintenance needs, many HVAC contractors in Grand Rapids and throughout the country offer HVAC maintenance plans. HVAC maintenance plans go by many names – you may also hear a heating and cooling contractor refer to them as preventative maintenance agreements, PMAs, service agreements, service plans, or another similar term. While terms vary by company, HVAC maintenance plans include annual heating and cooling tune ups, and often other valuable perks such as discounts and priority service.

Why Should Homeowners Enroll in HVAC Maintenance Plans?

Enrollment in an HVAC maintenance plan provides various benefits that offer value to the homeowner.

  • Your annual heating and cooling system tune ups are covered under HVAC maintenance plans. Maintenance plan members are already on the contractor’s radar, so tune up services can be completed ahead of heating and cooling seasons. Many HVAC maintenance plans include priority scheduling of these appointments, and the company will call you to set a date and time that’s convenient for you. You don’t have to remember to make the call and schedule these services yourself, risking the possibility of forgetting.
  • HVAC maintenance plans ensure your heating and cooling systems receive the dedicated care they need each year to improve performance for better comfort, ensure peak operating efficiency for lower energy costs, reduce the impact of wear and tear to prevent breakdowns and keep your unit in service longer. Tune ups also uphold the terms of your equipment warranty so this protection will be valid should you ever need it.
  • Most HVAC maintenance plans include much more than two annual system tune ups, though. Contractors often offer extra perks for maintenance plan members that go beyond maintenance and enhance convenience and control costs for the homeowner when other services are needed. Repair discounts lower the cost of any repair that may pop up over the season. Equipment discounts and credits can lower the price of new heating and cooling systems when it’s time to replace your units.

What Are the Benefits of a Programmable Thermostat?

July 19th, 2021
Thermostats

The summer heat can drive up energy bills for homeowners in the Grand Rapids and Lansing, Michigan areas. With the right tools, though, you can gain increased control over cooling system usage as well as home comfort. Consider having a programmable thermostat installed to save energy and lower heating and cooling bills.

In our most recent blog, the HVAC technicians at A-1 Mechanical discuss the benefits of programmable thermostats and why you should have one installed in your home.

Cut Summer Air Conditioning Costs

Reduced heating and cooling system energy consumption is one of the most well-known benefits of a programmable thermostat. Starting around the turn of the century, this technology has been promoted as a gold standard for HVAC system control and energy conservation.

The programming features help homeowners achieve the lengthy periods of temperature setbacks needed to generate noticeable energy savings related to heating and cooling. Homeowners are able to schedule six or more temperature adjustments in a day, making it easy to program comfortable, cool temperatures when the family wakes up and returns home after a day away. They can also automatically set temperatures higher during long periods when the household is away or asleep.

The U.S. Department of Energy states that you can save as much as 10 percent on cooling costs when thermostats are turned up 7 to 10 degrees higher than the usual home temperature for just 8 hours each day. The scheduling benefits of a programmable thermostat help homeowners easily achieve such energy savings without making multiple trips to the thermostat each day.

Ensure Precision Comfort, 24 Hours a Day

The scheduling benefits of a programmable thermostat offer more than just energy savings – this technology allows homeowners to precisely cool their living spaces according to the family’s unique routines. Setting higher temperatures to generate savings can create some discomfort when a manual thermostat is used, as the home cannot return to lower, more comfortable temperatures until someone is physically present to make the adjustment.

One of the important benefits of a programmable thermostat is the availability of multiple scheduling capabilities. Programmable thermostat models are available in four unique configurations, allowing homeowners to choose the option that best fits the day-to-day comings and goings of the household.

  • A 1-week model runs the set daily temperature schedule every day of the week.
  • A 5-2-day model allows one set of temperature schedules each weekday, while a unique temperature schedule can be programmed to run on the weekend days.
  • A 5-1-1-day model lets you program one set of temperature schedules to run each weekday, as well as a unique schedule on Saturday and another unique schedule on Sunday.
  • A 7-day model allows unique temperature schedules to be programmed for each of the seven days of the week.

Following the household’s daily routine, temperature adjustments can be scheduled to start slightly before family members arrive home or wake up. Program your thermostat to initiate a temperature change, bringing the indoor temperature down from a lengthy setback period about 15 minutes before the household becomes active. This will bring the home to a comfortable temperature when everyone is home and awake to enjoy it. Also, schedule setback periods to start about 15 minutes or more before the home empties or the household heads to bed – the living areas will stay cool during this period without additional energy usage by the air conditioning system.

If daily plans suddenly change, it’s no problem when your programmable thermostat is equipped with features like Wi-Fi connectivity! Remote access is one of the valuable benefits of a programmable thermostat that has a wireless Internet connection. Using a mobile app, you can adjust thermostat settings from just about anywhere!

Why Is My Air Conditioner Blowing Hot Air?

July 19th, 2021
Air Conditioning

Cool air blowing throughout your home provides a refuge from hot summer days. When you find the air conditioner blowing warm air, your frustration levels are likely to rise alongside the heat within your house! As frustrating as it may be, air conditioning, or AC, blowing hot air is actually a pretty common problem. Many causes may be resolved with some DIY troubleshooting of your air conditioning unit.

As a local Grand Rapids business, the technicians at A-1 Mechanical aim to protect the safety of our neighbors. Before you experience an issue within your AC unit know the most common causes, what to do to fix it, and when to call in our expert air conditioner repair pros for solutions. This may keep your AC unit blowing cold air without interruption.

Causes Behind an Air Conditioner Blowing Warm Air

If you have an air conditioner blowing hot air during the summer months, here are the most common causes and what you can do to correct them or when you should call for AC repair services.

Incorrect Thermostat Settings

In larger households, it’s easy for thermostat settings to be adjusted without the knowledge of other family members. If someone accidentally turns the thermostat to HEAT mode, it won’t be your air conditioning system generating hot air – it’s actually your furnace running, heating the home! If vents are blowing warm air check your thermostat first.

Another issue with thermostat settings that can send hot air into the home is a fan set to ON mode instead of AUTO. When the AUTO setting is selected, your HVAC system’s fan only runs with a cooling cycle to circulate chilled air into living spaces across the house. When ON mode is selected, the fan will run all the time. In between cooling cycles, the fan pushes warm air through the vents, because air is not actively being cooled.

Some thermostats feature a lock setting. This feature prevents switching between modes and adjusting the temperature settings. Since many homeowners only interact with the thermostat occasionally, it is easy to think you changed modes even though the thermostat was locked. In these cases, the issue is simple to resolve.

Whenever you have an AC system that’s blowing hot air, it’s wise to check the thermostat settings first.

  • Make sure the thermostat switch is set to COOL mode, not HEAT or HEAT/COOL.
  • Check the fan settings switch and make sure it is set to AUTO mode, and not ON.
  • On smart thermostats you should verify that the app is working by adjusting settings directly on the display.

As they age, thermostats can become faulty. Components may corrode and fail due to time, power surges and other factors. If the display is not working properly or if the thermostat is over 10 years old, our team can install a new thermostat and improve the efficiency of your system.

Dirty Air Filter

A dirty air filter can cause your air conditioner to blow hot air out of the vents. When contaminants build up, a blockage may be created. Clogged air filters force your cooling system to work harder, starving the system of the air needed to circulate smoothly. Your air handler may not be able to generate enough airflow, leaving the air feeling warm as it exits your vents. All the while, clogged air filters will be wasting electricity as the air handler attempts to compensate for the restricted filter.

When your AC is blowing hot air, check your HVAC filter and replace it as needed. It’s wise to check air filters once per month in the summer, as replacement may be needed more often during this season of increased system usage.

  • Remove the old filter from the filter cabinet.
  • Look at the filter’s surface – if it is completely caked in grayish material, it needs to be replaced. If you are unsure, hold the filter up to a light and see if you notice any light shining through. If no light passes through the filter, replace it. The basic rule is to replace dirty filters once every month during the hottest and coldest months.
  • Insert a new filter into the filter cabinet. Make sure to follow the airflow arrows on its frame which tell you the proper direction for filter installation. Make sure the filter is the correct size and fits snugly into the cabinet.


Dirty Outdoor Unit

Blowing warm air may also be due to blockages and clogs in the outdoor unit. A unit needs airflow to work optimally and stay cool. A dirty outdoor unit may overheat or experience unnecessary failure. During annual tune ups our technicians completely inspect and condition the AC unit. Detecting a refrigerant leak, damaged refrigerant line and especially dirty condenser coils is part of professional maintenance. If your outdoor AC unit is dirty, you should refer to the owner’s manual and most likely contact our team.

AC Coils

Frozen evaporator coils should prompt a call to our team. Your central air conditioner or heat pump uses two sets of coils – the indoor evaporator coil, and the outdoor condenser coil. If either of these coils are dirty, the system struggles to complete heat transfer, which can result in your AC blowing warm air. A dirty evaporator coil prevents it from absorbing heat within the indoor air; dirt on the condenser coil, meanwhile, prevents the system from efficiently releasing heat outdoors.

Coil cleaning is a job best left to the professionals. If you suspect your coils may be dirty, you can check by disconnecting power to the system and opening the access door to your furnace or air handler indoors to check the condition of the evaporator coils, or look inside the outdoor condenser unit or heat pump unit to check the condenser coils. If either are covered in dirt or grime, call your HVAC company to clean the coils.

Contact A-1 Mechanical for Relief from Hot Air

If you have an AC blowing warm air and the above troubleshooting steps don’t work, call A-1 Mechanical to perform air conditioner repairs at your home. Our technicians perform diagnostics to find out why you have an air conditioner blowing hot air so the correct repairs can be made to solve the problem once and for all.

Why Is My Air Conditioner Running, but Not Cooling the House?

June 4th, 2021
AC System

It seems like each summer is hotter than the last. Brutally hot summers make air conditioning a necessity. Before summer starts, turn on your air conditioning system to make sure it runs and is efficiently cooling your home.

A common issue the technicians at A-1 Mechanical frequently see during the summer months is an AC that is running but not cooling the house down. If this is the case, A-1 Mechanical has a few steps you can try to make your home cool again. In our most recent blog, we’ll explain what you can do yourself and when it’s best to call a professional HVAC company.

Troubleshooting Your AC Problems

If your air conditioner is running but not cooling your house, doing a little poking around yourself might just solve your problem without calling an HVAC company. Even if you can’t fix it, you can save your technician a lot of time by telling them what you’ve tried already.

Thermostat Set Incorrectly

This might seem silly, but it happens all the time. Make sure your thermostat is set to “cool” and is set at the desired temperature. Sometimes people accidentally turn the fan on but don’t turn the air conditioner on. This won’t cool your house.

Dirty Air Filter

This is one of the most common causes for a system that is running but not providing any cooling. On your air conditioner, there is an air filter that catches dust, dirt, and airborne particles. If your HVAC filter is clogged, it can restrict the airflow to the air conditioner. Replacing the filter might be the solution.

Frozen Air Conditioner

If you’ve replaced the filter and are still not feeling cold air, then peek inside your air conditioner. If you find ice or condensation, then your air conditioner might be frozen. There are a few reasons as to why this could happen. Turn off the air conditioner and melt the ice before you call a technician. You can do this by turning on only the fan on the air conditioner or using a hairdryer to speed the process along. Once the ice is melted, try running the AC again.

When to Call an HVAC Technician

Did you try all those steps and still don’t have relief? Then it’s time to call an HVAC system technician. Here are a few other common problems that are best solved by A-1 Mechanical’s air conditioner service team.

Condenser Unit Is Blocked

A dirty or clogged condenser can also cause an AC system to run but not provide cooling. The condenser is a coil that pulls heat energy out of your home. These can get clogged with dirt, grass, and other airborne debris. It’s best to let a technician properly clean the coil to ensure no accidental damage.

Refrigerant Leak

Refrigerant is a chemical that cools the air before it’s transmitted into your home. It is not like the oil for your car that needs to be replaced regularly, but if it does start leaking, it could cause problems. An AC technician will be able to refill your refrigerant to proper levels and stop any leaks.

Do I Need to Replace My Air Conditioner?

Don’t fret if your AC unit is running but not providing cool air. The best indication for replacing your air conditioner is the age of your unit. Because air conditioners are outside, they have a shorter lifespan than furnaces and usually last about 15-20 years. If your air conditioner is older than that, you might want to consider an upgrade.

Call A-1 Mechanical to Stay Cool This Summer

The best way to make sure your air conditioner keeps you cool is by having it inspected and cleaned in the spring. An A-1 technician will be able to replace any defective parts and let you know if you’re due for an upgrade. Call A-1 Mechanical today to schedule your seasonal AC checkup.

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.

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.
