Furnace Not Working? The 5 Most Common Causes We See in Orange County
1. Dirty flame sensor — the furnace lights, runs for a few seconds, then shuts off. A 20-minute cleaning or replacement. 2. Failed hot-surface igniter — you hear the blower but never hear the burners ignite. 3. Clogged filter tripping the high-limit switch — the furnace overheats and blows cold air; a new filter plus a limit reset usually fixes it. 4. Bad blower capacitor or motor — a hum with no airflow. 5. Thermostat or control board faults — the system never gets the call for heat. Because Aerosphere holds both HVAC and electrical licenses, we also catch the tripped breaker or undersized circuit that other companies miss.

Get Ready for Winter: Book a Tune-Up Before the First Cold Night
Eight out of ten no-heat calls we run in December and January come from furnaces that were never serviced. A $129 pre-season tune-up catches cracked heat exchangers (a carbon-monoxide risk), weak igniters and dirty burners while it is still 70 degrees outside — and members of our maintenance plan get it included with priority scheduling. Call 714-499-6656 or book online.

Furnace & Heating Repair FAQ — Orange County
Why is my furnace blowing cold air?
The most common causes are a dirty flame sensor, a failed igniter, a tripped high-limit switch from a clogged filter, or a thermostat set to FAN ON. Replace the filter and set the fan to AUTO first; if it still blows cold, call us — most furnace repairs in Orange County are fixed the same day.
How much does furnace repair cost in Orange County?
Typical furnace repairs in Orange County run $180–$650: igniter or flame sensor $180–$350, blower capacitor $180–$280, gas valve $350–$650, control board $400–$800. Aerosphere Electric gives an upfront flat-rate quote before any work begins.
Should I repair or replace my furnace?
If the furnace is under 12 years old and the repair is under $800, repair usually wins. If it is 15+ years old, needs a heat exchanger or repeated repairs, a new high-efficiency furnace or a heat pump (with California rebates) is the better investment. We show you both numbers.
How fast can you get heat back on?
We dispatch 24/7 across Orange County from Fountain Valley. Most no-heat emergency calls are reached within 1–2 hours, and our trucks carry the common igniters, sensors, capacitors and boards to finish the repair in one visit.
Do you service heat pumps and mini-splits too?
Yes — heat pump repair, installation and maintenance, plus ductless mini-split systems, all under our C-20 HVAC license. As a C-10 electrician as well, we also handle the panel or circuit work a heat pump conversion needs.
