Your furnace stopped working in the middle of a Pittsburgh winter. Before you stress about the bill, here is what repairs actually cost so you know what to expect.
Common Furnace Repairs and Costs
Ignitor replacement: $150-$250. The most common furnace repair. If your furnace tries to start but never fires, the ignitor is usually the culprit. Quick fix, usually under an hour.
Flame sensor cleaning or replacement: $100-$200. If your furnace lights briefly then shuts off within seconds, the flame sensor is likely dirty or failed. A tech can clean or replace it fast.
Thermostat replacement: $100-$300. Sometimes the issue is not the furnace at all. A malfunctioning thermostat can cause no-heat situations, short cycling, or erratic operation.
Blower motor replacement: $300-$600. If the furnace fires but no air comes from the vents, the blower motor may have failed. You might hear humming but feel no airflow.
Draft inducer motor: $200-$500. This motor vents exhaust gases. If it fails, the furnace will not start as a safety precaution.
Control board replacement: $300-$600. The circuit board that controls the furnace sequence. When it fails, the system may not respond to thermostat commands at all.
Gas valve replacement: $300-$700. Controls gas flow to the burners. If it fails, the furnace will not fire.
Heat exchanger replacement: $500-$1,500+. The most serious and expensive furnace repair. A cracked heat exchanger is a carbon monoxide hazard. At this price point, full furnace replacement often makes more sense.
What Affects the Price
Age of the furnace. Older furnaces use parts that may be harder to source, increasing cost and wait time.
Time of year. Winter emergency calls cost more due to demand. Getting maintenance done in fall helps avoid peak-season pricing.
After-hours service. Evening, weekend, and holiday calls typically add $75-$150 to the service call fee.
Diagnosis complexity. Some problems are obvious. Others require extensive testing to isolate the faulty component, which adds labor time.
Repair vs Replace
Consider replacement when:
- The furnace is over 20 years old
- Repair costs exceed 50% of a new furnace price
- You have had 2+ repairs in the last 2 years
- The heat exchanger is cracked
- Energy bills keep rising despite maintenance
A new furnace in Pittsburgh costs $2,500-$6,000 for standard efficiency, $4,000-$8,000 for high-efficiency models, installed.
