What Is Heating System Repair?
Heating repair covers gas furnaces, heat pumps, boilers, and electric systems — restoring heat quickly with proper safety verification for gas-fired equipment.
Common Furnace Problems
Ignition failure ($200–$600): failed igniter or flame sensor. Heat exchanger cracks ($1,500–$3,500): allows combustion gases including CO into living space — serious, requires immediate action. Blower motor failure ($400–$1,500). Inducer motor failure ($400–$800): furnace won't fire when this fails.
Heat Pump Heating Issues
Heat pumps lose efficiency below 35–40°F and should switch to backup heat — check that backup is functioning. Refrigerant leaks affect both heating and cooling. Reversing valve failure ($300–$800) prevents mode switching. Defrost cycle issues cause ice buildup.
Carbon Monoxide Safety
Gas appliance repair always involves CO risk. A licensed HVAC contractor will inspect the heat exchanger and gas connections. Install CO detectors on every floor, especially near sleeping areas and gas appliances. If your CO detector alarms, evacuate immediately and call 911.
Boiler Systems
Boilers require specialized technicians — not all HVAC contractors know hydronic systems. Common issues: pressure loss, zone valve failures, circulator pump failure, and kettling from scale buildup. Annual boiler maintenance is essential.
What to Look for in a HVAC Provider
- State HVAC contractor license (required in most states) and EPA 608 certification for refrigerant handling
- NATE (North American Technician Excellence) certification — the industry's highest technical standard
- Experience with your specific equipment brand (ask about their top manufacturer relationships)
- Transparent flat-rate or hourly pricing disclosed before the technician arrives
- Manufacturer-authorized for warranty repairs on your brand
- Maintenance plan options that include priority emergency scheduling
