One symptom, many possible causes. That is the core challenge of HVAC repair, and it matters even more in Los Angeles, CA, where failures seem to wait for the most extreme weather of the year. Equipment that will not start at all might have a failed low-voltage transformer, a thermostat that has stopped calling, a control board that has lost its sequence, or a float switch shut off by a backed-up condensate drain. Equipment that runs but never catches up is a different list: a weak capacitor, a worn contactor, a low charge, a dirty flame sensor, or a clogged filter choking off the blower.
The repairs homeowners call us about most are AC Repair and Furnace Repair. Start there if your system isn't running right.
Signs You Need HVAC Repair in Los Angeles
The sooner you notice these red flags, the easier and cheaper the fix. Keep an eye out for the following clues:
- Airflow at the registers that feels weak in every room
- Higher energy bills with no improvement in comfort
- Vents blowing warm when you want cool, or cool when you want heat
- Frequent on-off cycling while the house never gets to the thermostat setting
- Grinding, squealing, buzzing, or banging you have not heard before
- A breaker that trips whenever the system tries to run
- An outside unit that buzzes but will not start
- Puddles near the furnace or air handler from a blocked drain line
