What to Do When Your AC Stops Working in a Heat Wave

An air conditioner failing during a New Jersey heat wave is stressful, but a clear plan helps you stay safe and comfortable while you arrange repair. Start with a few quick checks, then focus on managing the heat.

Quick Checks to Try First

Before assuming the worst, confirm the thermostat is set to COOL and below room temperature. Check your electrical panel for a tripped breaker and reset it once if needed. Look at the air filter; a severely clogged one can shut the system down. Make sure the outdoor unit is clear of debris and running. These simple steps resolve a surprising number of no-cooling situations.

Keep Your Home Cooler

If the AC will not restart, reduce heat gain. Close blinds and curtains on sun-facing windows, avoid using the oven and other heat-generating appliances, and keep doors closed to trap cooler air. Run ceiling and portable fans to keep air moving.

Stay Safe in the Heat

Hydrate frequently and watch for signs of heat exhaustion, especially in children, older adults and anyone with health conditions. If your home becomes dangerously hot, spend time in a cooler location such as a mall, library or a friend's home until service is restored.

Call for Professional Help

If the quick checks do not work, call for repair promptly. A complete cooling failure in extreme heat is exactly the situation emergency AC service exists for. Avoid repeatedly restarting a system that will not cool, which can cause further damage.

With a calm approach and fast professional help, you can get through a heat wave safely and restore comfort as quickly as possible.
