What should I do if my AC stops working in the summer?

If your AC stops working in the summer, here’s a quick step-by-step guide to troubleshoot before calling a pro:

---

✅ 1. Check the Thermostat

• Make sure it’s set to Cool and the temperature is lower than the room temp.
• Replace batteries if it’s a battery-powered thermostat.

✅ 2. Inspect the Air Filter

• A clogged filter can restrict airflow and shut the system down.
• Replace if it looks dirty.

✅ 3. Check the Circuit Breaker

• Look for a tripped breaker for the AC or air handler.
• Reset once if it’s tripped.

✅ 4. Inspect the Outdoor Unit

• Make sure the condenser isn’t blocked by debris, grass, or leaves.
• Clear space around it for proper airflow.

✅ 5. Check the Drain Line

• A clogged condensate drain can trigger a safety shutoff.
• Look for standing water or use a wet/dry vacuum to clear it.

✅ 6. Let the System Rest

• Turn it off for 15–30 minutes, then restart.
• Sometimes this resets safety sensors.

✅ 7. Call an Klein HVAC Professional

• If the AC still doesn’t run, call a licensed technician.
• In Florida’s summer heat, don’t delay repairs — quick action prevents further damage and keeps your home safe.
