Air Handler Installation & Repair in Los Angeles
Power Pro Plumbing, Heating & Air installs, repairs, and maintains air handlers, the indoor blower, coil, and filtration unit that moves conditioned air through your home, across Los Angeles and Orange County, on all major brands.
Our certified technicians work on all major brands, match replacement units precisely to your outdoor equipment (a mismatched pair wastes efficiency from day one), and size blowers to your ductwork so every room gets its share of air.
For more than 20 years, our reputation has been built on transparent diagnostics and honest recommendations — we'll tell you whether your air handler needs a part, a cleaning, or a replacement, and exactly what each costs before any work begins.
What does an air handler do?
An air handler is the indoor cabinet that moves conditioned air through your home. Inside it: a blower motor that circulates air through your ducts, an evaporator coil where the air is actually cooled (or warmed, with a heat pump), filtration that catches dust and allergens on every pass, and the controls coordinating it all. Because every cubic foot of conditioned air in your home passes through it, air handler health directly determines comfort, air quality, and operating cost.
What are the signs of air handler trouble?
Call for an air handler diagnostic when you notice any of these signs:
- Weak airflow from vents even with a clean filter
- Squealing, rattling, or humming from the indoor unit
- Water around the unit — a clogged condensate line or frozen coil
- Rooms that never reach temperature despite the system running
- Musty smells suggesting microbial growth on the coil
- Rising energy bills as a failing blower motor draws more power
Why do matched equipment and right-sized airflow matter?
When replacement is warranted, matching matters: the air handler's coil and blower must pair correctly with your outdoor condenser or heat pump for the system to deliver its rated efficiency and capacity. We spec matched systems, verify airflow against your ductwork's real capacity, and commission the installation with measured static pressure and temperature split — the numbers that prove it's working, not just running.
Air Handlers FAQs
What's the difference between an air handler and a furnace? +
A furnace burns gas to create heat and includes its own blower; an air handler doesn't burn anything — it houses the blower and coil that circulate and condition air, typically paired with a heat pump or AC. All-electric homes usually have air handlers; gas-heated homes have furnaces doing double duty.
How long do air handlers last? +
Typically 10–15 years, similar to the outdoor unit they're paired with. Regular maintenance — clean filters, coil cleaning, condensate line care — is the biggest factor in reaching the high end.
Why is water leaking from my air handler? +
Usually a clogged condensate drain line backing up, or a frozen evaporator coil melting between cycles. Both are fixable, and both can cause ceiling or closet water damage if ignored — worth a prompt call.
Can I upgrade filtration at the air handler? +
Yes — the air handler is exactly where whole-home filtration upgrades live: high-efficiency media filters, HEPA-grade options, and UV lights that keep the coil clean. We'll recommend options that your blower can actually support, since overly restrictive filters hurt airflow.
