Michigan's Air Handler Experts

In your home’s HVAC system, an air handler, also known as an AHU or fan coil, plays a vital role in distributing heated or cooled air. These units, usually encased in metal and found in spaces like attics or basements, are made up of various important components:

  • Blower or fan: Moves air through the system and distributes it throughout the home
  • Evaporator coil: Extracts heat from the air to cool it before recirculating
  • Heating elements: Warms the air when needed
  • Air filter: Captures dust and particles to improve air quality
  • Electrical and electronic components: Manage and control the system’s operation

If you live in a warm climate where hot days are common, then you probably have an air handler system. An air handler is used to regulate and circulate air as part of a heating, ventilation, and air conditioning system. It works with your air conditioner or heat pump to make your home more comfortable. If you need assistance repairing, maintaining, or installing a new air handler, our team of professional technicians can help you!

There are many components of an air handler and below are some common issues you may have:
  • Thermostat: If your HVAC system isn’t working properly, you can check the thermostat settings and replace the batteries if needed. If that doesn’t work, you might need to replace the thermostat.
  • Refrigerant leaks: Low refrigerant can make your unit work harder to cool your home, which can increase your electricity bill. If the leak isn’t fixed, it will continue and require service.
  • Dirty filters: Filters can become clogged with dust, hair, and other debris after a few weeks of use. A clogged filter can make the fan work harder and cause excessive noise.
  • Dirty coils: Dirt on condenser coils can prevent the system from transferring hot air outside, which can affect your energy bill. You can have an HVAC professional clean the coils, or you can try doing it yourself if you’re comfortable.
  • Blocked drain: Pollutants like dust, dirt, and pet dander can stick to the drain pan during the cooling process and cause it to clog.
  • Frozen evaporator coil: If your air conditioner isn’t cooling properly, it could be because the evaporator coil is frozen. This can happen if the unit doesn’t get enough air to operate normally due to debris build-up.
  • Leaking ducts: Leaks in the ductwork can cause a 30% loss of air moving through the ventilation system, which can make your air conditioner work harder. Professionals will need to seal the ducts to fix this problem.

Air Handler F.A.Q

Frequently Asked Questions

An air handler, also known as an AHU or fan coil unit, is the indoor component of your HVAC system responsible for circulating conditioned air throughout your home. It works in combination with your outdoor unit, either a central air conditioner or heat pump, to deliver heated or cooled air through your ductwork. A

standard air handler contains a blower fan that moves air through the system, an evaporator coil that cools the air, heating elements for warmth, an air filter, and the electrical components that control operation. Air handlers are typically installed in attics, basements, or utility closets and are a core part of any ducted HVAC system in homes in Jackson County and the surrounding areas.

Air handlers should be professionally serviced once a year as part of your regular HVAC maintenance. Annual service includes inspecting all internal components, cleaning the evaporator coil, checking and replacing the air filter, lubricating moving parts, and checking for any signs of refrigerant leaks, drainage issues, or electrical problems.

Keeping up with annual maintenance helps the system run more efficiently, extends its lifespan, and reduces the chance of an unexpected breakdown.

Common signs that an air handler needs attention include rattling, banging, or squealing noises coming from the unit, uneven heating or cooling throughout the home, reduced airflow from the vents, musty or unusual odors, water leaking around the indoor unit, or a sudden spike in energy bills.

Ice forming on the evaporator coil is also a red flag that something is wrong, often caused by restricted airflow or a refrigerant issue. If the air handler is more than 10 to 15 years old and experiencing recurring problems, replacement may be more cost-effective than continued repairs.

Aspen One Hour Heating & Air Conditioning can inspect your system and give you an honest assessment.

Single-speed air handlers run at full capacity any time they are on, which can lead to temperature swings and higher energy use since the system cycles on and off frequently. Multi-speed air handlers can operate at two or more preset speeds, giving the system more flexibility to match the actual cooling or heating demand of the home.

Variable-speed air handlers are the most advanced option, running at a wide range of speeds and automatically adjusting output to maintain precise, consistent comfort. Variable-speed units also do a better job of controlling humidity, run more quietly, and are significantly more energy efficient over time.

For Michigan homeowners looking to maximize comfort and lower utility bills, a variable-speed air handler is worth considering when it is time for a replacement.

The most common air handler problems include dirty or clogged air filters that restrict airflow and strain the blower motor, frozen evaporator coils caused by poor airflow or low refrigerant, refrigerant leaks that reduce cooling efficiency, a blocked condensate drain line that can cause water damage if left unaddressed, dirty coils that make the system work harder, and leaky ductwork connections that reduce how much conditioned air actually reaches your living spaces.

Many of these issues are preventable with regular maintenance. When problems do come up, catching them early almost always means a less expensive repair.
