How to Protect Your AC Unit During Power Outages

Table of Contents

1. Turn Off the AC When the Power Goes Out

Leaving your AC on during an outage can cause a surge when electricity is restored. To avoid this:

  • Switch off the AC at the thermostat.
  • Turn off the breaker for added protection.
  • Wait before turning it back on once power is restored.

2. Use a Surge Protector

A whole-house surge protector or a dedicated one for your AC can help:

  • Prevent voltage spikes from damaging sensitive parts.
  • Extend the lifespan of your unit.

3. Keep Your Home Cool Without Power

To maintain a comfortable temperature:

  • Close blinds and curtains to block heat.
  • Use battery-powered or hand-held fans.
  • Stay in shaded or lower-level areas of your home.

4. Delay Restarting Your AC

Once power returns:

  • Wait 5–10 minutes before turning the unit back on.
  • Check for unusual noises or poor airflow.
  • Reset the circuit breaker if necessary.

5. Consider a Backup Generator

If you experience frequent outages, a generator can:

  • Keep your AC running during blackouts.
  • Prevent excessive humidity buildup in your home.

Conclusion

Taking the right steps during a power outage can save you from expensive AC repairs. Always turn off your unit, use a surge protector, and restart it carefully after an outage. For added protection, a backup generator can be a smart investment.
