About Our Furnace & Heating Service
Pittsburgh winters are no joke, and a furnace failure at 10 degrees is the last thing your family needs. Liberty Heating & Cooling repairs, replaces, and tunes up gas furnaces, electric furnaces, boilers, and high-efficiency condensing systems for homes across Allegheny and Westmoreland counties. We offer same-day service, upfront pricing, and 24/7 emergency response when you have no heat.
Penn Hills, Verona, and the older Pittsburgh East End neighborhoods are full of post-war ranches and split-levels still running their second-generation furnaces — units from the late 1990s and early 2000s that are now well past 20 years old. When we get called for a no-heat in 15235 or 15147, there's a 50/50 chance the homeowner has been nursing along a furnace that should be replaced rather than repaired, and we'll tell you honestly which side of the line yours falls on.
Newer Monroeville and Murrysville construction tends to have high-efficiency 95%+ AFUE condensing furnaces with PVC sidewall venting, and the most common failures we see there are pressure switches, inducer motors, and clogged condensate drains. Different equipment, different parts on the truck — we carry both. Local service pages: Furnace & Heating in Penn Hills · Furnace & Heating in Verona · Furnace & Heating in New Kensington

Our Furnace & Heating Process
- 1
Safety check first
On any no-heat call we test for carbon monoxide and inspect the heat exchanger before anything else. Your safety is non-negotiable.
- 2
Diagnostic with the system running
We test ignitor resistance, flame sensor microamps, gas pressure, inducer and blower amp draw, and pressure switch operation — the actual measurements, not guesses.
- 3
Honest repair-vs-replace conversation
If your furnace is over 15 years old and the repair is significant, you'll see both quotes side by side. If repair is the right call, we say so.
- 4
Same-day fix on common parts
Ignitors, flame sensors, capacitors, pressure switches, inducers, and gas valves for major brands are on the truck. Most no-heat calls leave with the heat back on.
- 5
Combustion verification
After any furnace repair we verify combustion CO, draft, and temperature rise are within manufacturer spec, then leave a written report.
Frequently Asked Questions
How much does a new furnace cost in Pittsburgh?+
Furnace pricing depends on the unit size (BTU), efficiency rating, and whether any venting or gas line modifications are needed. An 80% AFUE unit and a 95%+ high-efficiency condensing unit fall into different investment ranges. We provide a free, written quote before any work begins so you know exactly what to expect.
How long does a furnace last?+
A well-maintained gas furnace in Western PA typically lasts 15–20 years. If yours is over 15 years old, runs constantly, or has had multiple repairs, it's worth getting a replacement quote alongside the repair.
My furnace isn't turning on — what should I check first?+
Check the thermostat batteries and setting, confirm the furnace switch is on, check the breaker, and replace the air filter if it's dirty. If those don't fix it, call us — most no-heat calls are an ignitor, flame sensor, or pressure switch issue we can resolve same-day.
Do you offer 24/7 emergency furnace repair?+
Yes. We dispatch emergency furnace service 24/7 across the Pittsburgh metro at 412-583-0513. No overtime charges on emergency calls.
How often should I service my furnace?+
Once per year, ideally in early fall before heating season. Annual tune-ups catch cracked heat exchangers, dirty burners, and worn ignitors before they cause a mid-winter breakdown — and most manufacturer warranties require it.
Is a cracked heat exchanger really a big deal?+
Yes. A cracked heat exchanger can leak carbon monoxide into your home's air supply. We will not patch one — federal code and every manufacturer requires replacement of the heat exchanger or the furnace itself. If a contractor offers to weld or seal one, get a second opinion.
Should I get a high-efficiency 95%+ AFUE furnace?+
If your home has a chimney suitable for sidewall venting or already has PVC venting, 95%+ AFUE almost always pays back within the equipment's lifetime in Pittsburgh's climate. If your chimney would need a liner or the venting run is impractical, an 80% AFUE unit may make more sense — we'll do the math for your specific home.
Why does my furnace short-cycle?+
Most common causes: dirty flame sensor, oversized furnace for the home, restricted return airflow, or a failing limit switch. Short-cycling shortens equipment life dramatically, so it's worth diagnosing quickly.
Do you service oil furnaces?+
We service oil furnaces in pockets of the area where they're still common, and we do a high volume of oil-to-gas conversions. If you're considering converting, ask for a written comparison of fuel cost, equipment cost, and payback.
