   • Fuse: If your AC unit uses a fuse, inspect it for any signs of damage or a broken filament. Replace the fuse with one of the same amperage rating.
   • Power Cord: Ensure the power cord is securely plugged into the outlet. Try plugging another appliance into the outlet to verify that it’s working.

2. Examine the Thermostat: Same Day Ac Repair Near Me Ac Repair Contractor 24 7 Ac Repair Near Me

   • Settings: Make sure the thermostat is set to "cool" mode and that the temperature is set lower than the current room temperature.
   • Batteries: Replace the batteries in the thermostat, even if they seem to be working. Low batteries can cause erratic behavior.
   • Wiring: If you’re comfortable doing so, carefully inspect the wiring connections to the thermostat. Ensure that all wires are securely connected and that there are no loose or damaged wires.
   • Test: If you have a multimeter, you can test the thermostat’s functionality. Consult your thermostat’s manual for instructions on how to perform this test. If you have a smart thermostat, try resetting it.

3. Inspect the Air Filter: Austin Air Conditioning Repair Air Conditioning Repair Contractor Commercial Hvac Repair Near Me
