A/C Troubleshooting Tips

AC TroubleshootingThe summer heat is coming and that means more people will be firing up their air conditioning or cooling units to keep their homes comfortable. If you crank up the A/C and aren't feeling the chill, there are some things you can check before calling your Carolina Comfort Systems technician out for a service call.

1. Check the outside unit for obstructions and debris. Inspect the outdoor unit to make sure no leaves, twigs or other debris are stuck in the unit or interfering with proper operation. Clear away any debris you find.

2. Check the disconnect switch connected to the outside unit. This is usually a power box mounted on a wall near the outside unit. You'll want to make sure the disconnect switch is in the "ON" position.

3. Check the air filter for your HVAC unit. Excessively dirty filters restrict airflow and can cause some units to shut down for safety. Replace the filter with a brand new one and make sure to change the filter monthly going forward.

4. Check your thermostat for proper operation. Make sure your thermostat is on the "COOL" setting. Make sure the display is fully visible and is not giving a beeping noise, which could indicate a low battery. If the display is not visible, is flashing or the thermostat unit is beeping, put fresh batteries in the unit and check operation.

5. Make sure the blower is running. Turn the thermostat's desired temperature below the current temperature shown in the room. If you don't hear the blower kick on, check the on/off switch on the indoor furnace unit to make sure it is in the "ON" position.

6. Check the circuit breaker in the breaker box to look for a tripped fuse/breaker.

7. Check air vents and air returns to ensure nothing is blocking the registers. Furniture, boxes or other items blocking an air vent or return register can cause the system to shut down for safety.

If you've checked all of the above issues and are still having trouble with your cooling system, it's time to call your technician at Carolina Comfort Systems to take a look. Help prevent future breakdowns before they happen with regular scheduled maintenance and inspection of your HVAC system at least once per year.
