Start with thermostat, filter, and breaker. Then call a licensed HVAC technician. Aerosphere Electric handles furnace diagnostics 24/7: (714) 499-6656.

What is the most common furnace repair?
The most common furnace repair in Orange County is ignitor replacement, followed by flame sensor cleaning or replacement. Both are wear items that typically fail every 5-10 years. Symptoms: furnace clicks but won't light, furnace lights briefly then shuts off, or furnace blower runs but no heat. Combined cost typically $200-$550.
When should I replace my furnace instead of repairing it?
Replace your furnace if: the unit is over 18-20 years old, the heat exchanger has cracked (carbon monoxide risk), the repair cost exceeds 50% of replacement, or you are repairing the same component repeatedly. A new 96% AFUE furnace cuts heating bills 15-25%. Aerosphere Electric provides free written repair-vs-replace recommendations.

What is a cracked heat exchanger and is it dangerous?
A heat exchanger is the metal chamber that separates combustion gases from the air your furnace circulates. A cracked heat exchanger allows carbon monoxide (CO) to leak into your home air - extremely dangerous. Symptoms: yellow burner flames instead of blue, soot near vents, headaches that improve when you leave home. If your CO detector goes off, leave immediately. Replacement runs $1,500-$3,500, but most furnaces with cracked exchangers should be replaced entirely. Aerosphere Electric performs combustion analysis testing.
How often should I service my furnace?
Aerosphere Electric recommends annual furnace service, ideally in fall before peak heating season. Annual tune-ups include: burner cleaning, ignitor inspection, flame sensor cleaning, blower motor inspection, gas pressure check, combustion analysis, thermostat calibration, and safety inspection. Annual maintenance extends furnace life and maintains manufacturer warranty validity. Tune-ups run $89-$149.
