How long does a gas furnace last in Pittsburgh?

A well-maintained gas furnace typically lasts 15 to 20 years in Pittsburgh. The single most important thing you can do to extend its life is an annual fall tune-up, which catches small problems before they become expensive winter breakdowns.

What is the most efficient gas furnace I can buy?

Today's best residential gas furnaces operate at 96% to 98.5% efficiency. That means for every dollar you spend on natural gas, 96 to 98 cents becomes heat inside your home — compared to older furnaces that waste 30 to 35 cents up the chimney. We install Carrier, Trane, and Goodman systems in this range.

Gas Furnace Repair & Installation in Pittsburgh, PA

Q: Why is my gas furnace blowing cold air?

The most common reasons a gas furnace blows cold air are: a dirty air filter causing the furnace to overheat and shut off the burners while keeping the fan running, a failed ignitor that can't light the gas, a dirty flame sensor that shuts the burners off after a few seconds, or a thermostat fan switch set to ON instead of AUTO.

Q: How much does a new gas furnace cost in Pittsburgh?

A standard gas furnace installation in Pittsburgh costs between $3,800 and $5,500. A high-efficiency model (96%+ AFUE) ranges from $5,200 to $7,800 installed. High-efficiency systems qualify for up to $600 in rebates from Peoples Gas and Columbia Gas, and can save you $400–$700 every winter.

Pittsburgh's Most Common Home Heating System

Over 80% of Pittsburgh homes use natural gas as their primary heat source — and for good reason. Gas is widely available across Allegheny County, burns cleanly, and heats your home quickly even on the coldest January nights.

Think of a gas furnace like a controlled campfire connected to a powerful fan. The burners light the gas, metal chambers capture that heat, and a fan quietly pushes warm air through your home's ductwork into every room.

✓ Fast, powerful heat — warms your home even at 5°F outside
✓ Modern units are 96–98% efficient — almost no heat wasted
✓ Lower monthly fuel cost than oil or all-electric heating
✓ Natural gas is always available — no deliveries or running out
✓ Quiet, consistent warmth through two-stage and modulating systems

PROBLEM SOLVER

Common Gas Furnace Problems & What Causes Them

If your furnace isn't working right, here are the 6 most common issues Pittsburgh homeowners experience — explained in plain language with simple first steps you can take before calling us.

NO HEAT

Furnace Won't Turn On

Symptom: Your thermostat calls for heat but nothing happens — no click, no fan, no warmth

A few quick things to check first: make sure the thermostat is set to HEAT and the temperature is set higher than the room. Also check that no one has accidentally turned off the power switch near the furnace (it looks like a light switch). If those are fine, call us — it's usually a small ignitor or fuse issue.

COLD AIR

Fan Runs but Air is Cold

Symptom: Air blows from vents but it feels cold or only barely warm

This usually means the burner isn't lighting. The most common causes are a worn ignitor (the small part that sparks the gas) or a dirty flame sensor (a small rod that checks to make sure the flame actually started). Both are quick, affordable repairs — and we often fix them same-day.

SHORT-CYCLING

Furnace Turns On and Off Every Few Minutes

Symptom: The furnace starts, heats for a few minutes, shuts off, then starts again repeatedly

This is called short-cycling, and the most common cause is a clogged air filter. When air can't flow freely, heat gets trapped inside the furnace and a safety sensor shuts it off to prevent damage. Check your filter first — if it's grey and clogged, replace it. If that doesn't fix it, give us a call.

LOUD NOISE

Loud Banging When Heat Turns On

Symptom: A loud bang or boom when the furnace first kicks on

This 'bang' is usually caused by gas building up before it ignites — like a very small explosion. It's a sign your ignitor or burners need cleaning. It's not immediately dangerous, but it should be fixed soon because repeated bangs can crack the metal heat exchanger inside the furnace.

CALL US NOW

Furnace Smells Like Gas

Symptom: You notice a rotten egg or sulphur smell near the furnace or vents

A strong gas smell is serious. Leave the house, don't turn any lights or switches on or off, and call your gas company from outside. A faint smell when the heat first comes on for the season is normal — just dust burning off. But any persistent gas smell needs immediate attention.

UNEVEN HEAT

Some Rooms Are Cold, Others Are Warm

Symptom: Bedrooms upstairs feel cold while the living room is warm

Uneven heat is usually a ductwork or sizing problem, not a furnace failure. Closed or blocked vents, leaky duct connections, or an oversized furnace that short-cycles can all cause this. We test airflow room-by-room and suggest simple fixes — often just rebalancing your dampers.

FAQ

Your Gas Furnace Questions Answered

Why is my gas furnace blowing cold air?

The most common reasons: a clogged air filter causing the furnace to overheat and shut the burners off (while keeping the fan running), a worn ignitor that can't light the gas, a dirty flame sensor that shuts the burners off after a few seconds, or a thermostat fan switch set to ON instead of AUTO. Our $89 diagnostic finds the exact cause.

What should I check before calling for a repair?

First, check your air filter — if it's thick with dust, replace it and wait a few minutes before restarting. Next, check your thermostat is set to HEAT with the temperature above room temperature. Also check the furnace power switch (looks like a light switch near the furnace) is ON. If none of these fix it, give us a call.

How much does a new gas furnace cost in Pittsburgh?

A standard gas furnace installation costs $3,800 to $5,500. A high-efficiency 96%+ model runs $5,200 to $7,800 installed — but qualifies for up to $600 in gas utility rebates and saves you $400–$700 on heating bills every winter.

How long does a gas furnace last?

With annual tune-ups, a gas furnace typically lasts 15 to 20 years. The single best thing you can do to maximize that lifespan is change the air filter regularly (every 1–3 months) and schedule a professional safety check every fall.

Is it safe to run my gas furnace if I smell gas?

No. If you smell a strong rotten egg or sulphur odour, leave your home immediately without turning on or off any switches, and call your gas company from outside. A mild dusty smell when the heat first turns on in autumn is normal — just dust burning off.
