Short answer
Before Santa Ana winds arrive, change the air filter, clear leaves and debris from around the outdoor unit, rinse the condenser coil gently, and test the system on a warm day. Dust and heat together are hard on capacitors and coils, so a quick check prevents mid-heat-wave failures.
Why Santa Anas matter
They bring sudden heat, very low humidity and blowing dust in fall, when many people assume AC season is over.
Checklist
A quick routine:
- Replace the filter
- Clear 2 feet around the condenser
- Gently hose the coil from inside out (power off)
- Test cooling before the event
- Close windows to keep dust out
Not sure it is safe to keep running? A local technician can check it today.
