On Wednesday evening, more than 22,000 homes and businesses in Dana Point, Laguna Niguel, San Clemente, and San Juan Capistrano lost power during a widespread outage. While electricity was restored within a few hours for most residents, some homeowners discovered another problem once the lights came back on—their air conditioner wasn't working.
At Air Care Heating & Air Conditioning, we've already received several calls from homeowners experiencing this exact issue.
Can a Power Outage Affect Your HVAC System?
Yes. Although most air conditioners restart without any issues, power interruptions and voltage fluctuations can occasionally affect electrical components inside your HVAC system.
Some of the most common issues we see after a power outage include:
- Tripped circuit breakers
- Blown fuses
- Failed capacitors
- Damaged contactors
- Thermostat communication issues
- Safety controls preventing the system from restarting
The good news is that many of these problems can be repaired without replacing the entire system.
What Should You Check First?
Before scheduling service, there are a few simple things you can check:
Verify Your Thermostat
Make sure it's set to Cool and lower the temperature a few degrees below the current room temperature.
Check Your Breakers
Power outages can trip the breaker that supplies your indoor or outdoor unit.
Give the System Time
Many modern HVAC systems have a built-in delay that prevents the compressor from restarting immediately after power is restored. Waiting 5–10 minutes may solve the problem.
Listen for Unusual Noises
Buzzing, humming, or repeated clicking could indicate an electrical component that needs professional attention.
When Should You Call an HVAC Professional?
If your system won't turn on, is blowing warm air, or repeatedly trips the breaker after the outage, it's time for a professional inspection. Continuing to reset breakers or force the system to run can sometimes lead to additional damage.
