AAA Pro HVAC didn't start as a franchise rollout or a private-equity roll-up — it started with technicians who got tired of watching homeowners get overcharged for underexplained work.
We service both residential and light commercial systems across Derry, PA: split systems, packaged units, ductless mini-splits, gas furnaces, electric furnaces, and heat pumps.

Catching a problem early, before it becomes a total breakdown, almost always means a shorter repair and a smaller bill.
A system that runs but never actually cools usually means a refrigerant charge issue, a failing capacitor, or restricted airflow — not something a thermostat adjustment will fix. Ignoring warm air from the vents rarely makes the underlying issue cheaper to fix later.
A furnace that clicks but never lights, or one that lights and shuts off within seconds, usually points to a failing ignitor, a fouled flame sensor, or a safety switch doing exactly its job. Our Derry, PA techs see this specific pattern often enough to diagnose it quickly rather than guess.
Dirty coils, duct leaks, and failing components all show up on the utility bill before they show up as a total breakdown. Ignoring rising utility bills with no usage change rarely makes the underlying issue cheaper to fix later.
A grinding or squealing sound usually points to a motor bearing wearing out; a banging sound during startup often means a loose or broken internal component. Our Derry, PA techs see this specific pattern often enough to diagnose it quickly rather than guess.
This is one of the most misdiagnosed HVAC complaints, since it's tempting to blame the thermostat instead of the actual airflow path. Ignoring uneven temperatures room to room rarely makes the underlying issue cheaper to fix later.
Turning on and off every few minutes instead of running a full cycle strains the compressor and rarely resolves itself. Ignoring system short-cycling rarely makes the underlying issue cheaper to fix later.
