Air Handler Repair, Installation, and Replacement
An air handler unit (AHU), sometimes called an electric furnace, is a critical component of your air conditioning system. It houses the blower fan that distributes conditioned air throughout your home, maintains heat strips for backup heat on heat pump systems, and contains your indoor coil or evaporator coil where heat is removed to cool the air entering your home.
At Owyhee Heating, Air Conditioning & Plumbing, we have been serving the Boise, Idaho and Treasure Valley areas for over 70 years. We are committed to providing quality air handler repair, installation, and replacement services at affordable prices. Our experienced technicians understand the importance of keeping your air handler functioning properly for year-round comfort.
Common Air Handler Problems
- Clogged Fans: A clogged fan restricts airflow, affects refrigerant pressures, and can cause your system to freeze up. This issue extends far beyond simple fan blockage and requires prompt attention.
- Mold Growth: Mold can develop when your air conditioner is not removing enough moisture from the air or after water damage. If left unattended, mold spores will circulate throughout your home, creating health and air quality concerns.
- Rusting Components: Your indoor coil constantly has water running over it during operation. As the coil ages, copper can rust and eventually develop holes, leading to refrigerant leaks.
- Aging and Wear: As air handlers reach the end of their lifespan, wiring becomes brittle, heating elements weaken, coils wear out, and fan housings loosen.
The functionality of your air handler depends heavily on how well you maintain it and keep it clean. If you have pets in your home, maintaining superior indoor air quality is especially important.
Signs You Need Air Handler Replacement
Air handlers typically have a lifespan of about 10 years. If your unit is older than this, replacement should be considered. Several warning signs indicate it may be time for a new air handler:
- Frequent and recurring problems requiring constant repairs
- Reduced cooling performance compared to when the system was new
- Noticeably weaker airflow from your vents
- Excessive rust visible on the cabinet exterior, which indicates moisture problems and potential internal coil corrosion
- Unusual sounds or vibrations coming from the unit
- Rising energy bills despite consistent usage patterns
Excessive rust on the outside of your unit is particularly concerning, as it signals moisture issues inside that can lead to coil deterioration and mold growth. When you notice these signs, our team can assess your system and recommend whether repair or replacement is the most cost-effective solution for your home.
