What to Do If Your AC Stops Working During a Heatwave

When the summer heat hits hard and your AC suddenly gives out, it can feel like a crisis — especially during a heatwave. Don’t panic! Here’s what to do if your cooling system goes down when you need it most:

1. Check the Basics

Before calling for help, double-check:

  • Thermostat settings (make sure it’s on “cool” and the batteries aren’t dead)
  • Breaker panel (your AC might’ve tripped a circuit)
  • Air filter (a clogged filter can cause the system to freeze or shut down)

2. Try to Stay Cool

While waiting for repairs, use these quick fixes:

  • Close blinds or curtains to block out direct sunlight
  • Use ceiling or portable fans to circulate air
  • Drink lots of water and limit activity to stay cool

3. Don’t DIY the Repairs

It’s tempting to try and fix things yourself, but modern AC systems are complex — and you could do more harm than good. Call in a licensed HVAC technician to inspect and safely get your system back up and running.

4. Call for Emergency Service

During a heatwave, AC issues can be more than just inconvenient — they can be dangerous, especially for young children, seniors, or pets. If your system isn’t cooling and the temperature is rising, call us for emergency HVAC service right away.
