About Our Air Conditioning Service
Liberty Heating & Cooling provides full-service air conditioning repair, replacement, and installation throughout Pittsburgh and the surrounding suburbs. Whether your central AC stopped cooling, your system is more than 10 years old, or you're looking at a ductless mini-split for an addition, our certified technicians service every major brand and stand behind every job with a workmanship guarantee.
A huge share of the AC calls we run are in the older East End neighborhoods — Squirrel Hill, Point Breeze, Regent Square, and across the line into Penn Hills and Verona. These homes typically had central AC retrofitted into existing furnace ductwork, which means short line sets, undersized return air, and condensers crammed against a side wall. Our techs are used to working around those constraints without taking shortcuts on refrigerant charge or airflow.
On newer Plum and Murrysville builds, the most common issue we see is an oversized AC that short-cycles, never dehumidifies properly, and dies young. We always do a Manual J load calculation before quoting replacement so the new system actually matches the house.

Our Air Conditioning Process
- 1
On-time arrival and walkthrough
We confirm the symptoms you described, check the thermostat and air filter, and listen to the system run before we touch anything.
- 2
Full diagnostic
We test refrigerant pressures, capacitor and contactor health, blower amp draw, and the condenser fan motor. We also check static pressure to catch ductwork issues most contractors miss.
- 3
Upfront written quote
Before any repair, you see a written price for the fix and — if your system is aging — a side-by-side comparison with a replacement quote. No pressure to choose one.
- 4
Same-day repair when possible
Our trucks stock capacitors, contactors, fan motors, refrigerant, and the most common control boards, so the majority of AC repairs are completed in a single visit.
- 5
Verify and document
After the repair we re-check pressures and airflow, then leave you a written summary so you have a service history for warranty claims.
Frequently Asked Questions
How much does AC repair cost in Pittsburgh?+
AC repair costs vary based on the part and the system. A diagnostic visit identifies the issue and is credited toward your repair. Common fixes like capacitors or contactors are typically more affordable, while compressor or coil work is more extensive. We provide an upfront quote before any work begins.
How long does a new AC installation take?+
A straightforward central AC replacement on an existing line set usually takes 4 to 8 hours. A full new install with ductwork or a ductless mini-split system can take one to two days. We confirm the timeline before we start.
When should I replace my air conditioner instead of repairing it?+
We generally recommend replacement when the unit is 12+ years old, uses R-22 refrigerant, or the repair cost exceeds 40% of a new system. We always present both options so you can decide what fits your budget.
Do you service all AC brands?+
Yes. Our technicians service every major brand including Carrier, Trane, Lennox, Goodman, Rheem, York, Amana, Bryant, and American Standard, plus ductless brands like Mitsubishi and Daikin.
Do you offer emergency AC repair?+
Yes — we offer 24/7 emergency AC service across the Pittsburgh metro. Call 412-583-0513 for emergency dispatch.
How long does an AC last in Pittsburgh?+
Well-maintained central AC units in Pittsburgh typically last 12–15 years. Salt-air corrosion is not an issue here, but our humid summers are tough on coils and our freeze-thaw winters can crack refrigerant line insulation, so annual maintenance has a real impact on lifespan.
Can I just replace the outdoor unit and keep my old indoor coil?+
Almost never a good idea. Mismatched systems run inefficiently, often void the new unit's warranty, and the EPA refrigerant rules (R-410A phase-out, R-454B transition) make replacing only the condenser legally complicated. We'll walk you through the tradeoffs honestly.
Why does my AC freeze up?+
Three common causes: dirty air filter, low refrigerant from a slow leak, or a failing blower motor. The fix matters — running a frozen system can destroy the compressor. Turn the system off, set the fan to ON for an hour to thaw, then call us.
