An air handler is the indoor part of your HVAC system that moves heated or cooled air through your home. It contains key components like the blower motor, coils, and filters that work together to circulate clean, conditioned air efficiently.
Dirty coils can reduce airflow and efficiency. While it’s tempting to DIY, coil cleaning should be handled by a professional to avoid damaging delicate components. Mainstream offers thorough coil cleaning as part of our maintenance services to keep your system running strong.
Your air handler is typically found in a utility closet, attic, basement, or garage—wherever your HVAC system is housed. If you’re not sure where yours is located, our Mainstream technicians can help identify it and make sure it’s easy to access for maintenance.
An air handler usually looks like a large metal box with vents, access panels, and connected ductwork. Inside, it contains components like a blower, coils, and filter racks. It may look plain, but it’s a powerhouse behind your home’s airflow.
If your HVAC system isn’t keeping your home as comfortable as it should, the problem may not be your furnace or AC — it could be your air handler. This essential component is responsible for circulating air throughout your home, helping your heating and cooling system maintain a consistent temperature from room to room. When something goes wrong, your comfort, energy efficiency, and even indoor air quality can all take a hit.
At Mainstream Electric, Heating, Cooling & Plumbing, we offer expert air handler repair, replacement, and maintenance services across Spokane and Northern Idaho. Our licensed HVAC professionals work with all types of air handlers, from traditional split-system units to ductless mini-splits, ensuring your system gets the right solution with care, speed, and a neighborly attitude.
An air handler is the part of your HVAC system that moves heated or cooled air through your ducts and into your living spaces. It typically houses key components like a blower motor, evaporator coil, filter rack, and sometimes heating elements. It works hand-in-hand with your air conditioner, heat pump, or furnace to deliver consistent airflow and maintain your desired temperature.
Without a properly functioning air handler, even the most advanced HVAC system can struggle. You may notice hot or cold spots in your home, rising energy bills, reduced airflow, or even strange noises or smells coming from your vents.
If your HVAC system feels “off,” it could be your air handler trying to tell you something. Here are a few red flags to watch for:
Weak or inconsistent airflow from your vents
Unusual banging, rattling, or humming noises
Musty odors or signs of mold around your unit
Higher-than-usual utility bills with no explanation
Ice buildup on the evaporator coil
HVAC system short cycling or failing to turn on
If you’re experiencing any of these issues, call Mainstream to schedule a cooling system diagnostic or heating system tune-up. We’ll thoroughly inspect your air handler and identify the most cost-effective fix — or replacement, if needed.
Our team doesn’t believe in upselling or guesswork. If your air handler just needs a new capacitor, motor, or control board, we’ll fix it quickly and explain what went wrong. And if your unit is aging or inefficient, we’ll help you explore the benefits of a new energy-efficient air handler that integrates seamlessly with your existing system.
We work with trusted brands and install air handlers that are quiet, reliable, and built to last. Every installation includes proper ductwork checks and electrical service integration so your new system runs safely and efficiently from day one.
Air handlers work hard — and like any essential system in your home, they need routine maintenance to perform their best. Dust, debris, and moisture can build up over time, leading to airflow issues, efficiency loss, and even mold growth if left unchecked.
Mainstream’s expert maintenance services include:
Filter checks and replacements
Blower motor inspection and lubrication
Coil cleaning and condensate drain clearing
Electrical component testing
Airflow and temperature balancing
