Common furnace problems we fix

Furnaces usually give warning signs before they quit. Call us if you notice any of these:

  • Furnace blowing cold or lukewarm air. Often a dirty flame sensor, a tripped limit switch, a clogged filter or an ignition problem.
  • Furnace won’t turn on at all. We check the thermostat, power, safety switches, igniter and control board.
  • Short-cycling. The system starts, runs a few minutes, then shuts off before the house warms up.
  • Strange noises. Squealing, banging or rattling from the blower, burners or inducer motor.
  • Igniter or pilot problems. An igniter that won’t light, or a yellow flame instead of a crisp blue one.
  • Heat pump trouble. Iced-up outdoor coils, a stuck reversing valve, refrigerant leaks or a failed defrost board.
  • A sudden jump in your gas or power bill with no change in how you use your heat.

We repair gas furnaces, electric furnaces, heat pumps and ductless mini-splits. Common fixes include flame sensors, hot surface igniters, gas valves, draft inducer motors, blower motors, capacitors, sequencers, limit switches and thermostats. We work on all major brands, including Daikin, Trane, Rheem, Carrier, Goodman and Honeywell.

Safety note: If you smell gas, leave the house and call your gas utility or 911 first. Then call us.

How our furnace repair pricing works

No hourly billing, no surprise add-ons and no extra charge for nights, weekends or after hours. The $150 diagnostic and our flat-rate prices are the same 24/7. Here’s how it works:

1. $150 diagnostic visit. A licensed technician comes to your Norcross home, inspects the system, and finds the exact cause.
2. Flat-rate quote before any work. We explain the problem in plain English and give you an upfront, flat-rate price. You approve it before we start.
3. Diagnostic fee waived with most repairs. If you go ahead with the repair, the $150 diagnostic fee is waived in most cases.
4. Many furnace repairs starting as low as $250. The final price depends on the part and the system, but you’ll know it before we pick up a tool.
5. Full test after the repair. We run the system through a full heating cycle and check the safety controls before we leave.

Why is my furnace blowing cold air?

Should I repair or replace my furnace?
