Expert Insights
Pro Tips: Furnace Repair in San Diego
Before calling a technician, these checks can save time and help you describe the problem accurately.
Check the Air Filter
A clogged filter is the #1 cause of reduced airflow, frozen coils, and system overheating. Replace it every 1-3 months depending on usage.
Listen for Capacitor Failure
Run and start capacitors are among the most common HVAC failures. Symptoms: hard starting, humming without running, or unit not starting at all.
Never Ignore Refrigerant Loss
Refrigerant should not deplete unless there is a leak. Topping off without locating and sealing the leak is only a temporary and costly fix.
