Expert Furnace & Heater Repair
in Orange County
When the foothills get chilly, you need reliable heat.
We provide safe, fast diagnostics for gas furnaces and heaters.
Carbon Monoxide Safety Check included with every repair.
Is Your Furnace Dangerous?
A gas furnace is a combustion appliance. If it’s not working right, it’s not just uncomfortable — it could be unsafe.
- Red Flags: Yellow burner flames (instead of blue), soot buildup, or a “rotten egg” smell.
- Our Promise: We carry advanced combustion analyzers to detect invisible cracks in the heat exchanger that could leak Carbon Monoxide. If it’s not safe, we will tell you the truth.
Troubleshooting Your Heating Problems
We stock parts for Carrier, Trane, Lennox, York, and Goodman furnaces.
- Blowing Cold Air: Often a bad limit switch or pilot light issue.
- Short Cycling: Furnace turns on and off every 3 minutes. (Usually a dirty flame sensor or airflow restriction).
- Ignition Failure: The “click-click-click” sound but no fire. We replace worn-out hot surface igniters (HSI).
- Noisy Operation: Rumbling or scraping sounds from the blower motor.
The 50% Rule
We never push a new unit if a repair makes sense. However, for furnaces over 15 years old, we use the 50% Rule:
- If the repair cost is more than 50% of the value of a new system, it’s safer and smarter to replace. We will provide options for both repair and replacement so you can decide.
