 A/C Troubleshooting Tips 

When summer temperatures soar in Northampton, PA, a malfunctioning air conditioner can quickly become a major headache. At Action Plumbing Heating & HVAC, we understand how crucial it is to keep your home cool and comfortable. Here are some practical troubleshooting tips to help you identify and potentially resolve common A/C problems before calling in the pros.

1. A/C Not Turning On

Check the thermostat: Make sure it's set to "cool" and the temperature is lower than the current room temperature. Inspect the circuit breaker: A tripped breaker could be the culprit. Reset it and see if that restores power.

2. Weak or No Airflow

Change the air filter: Dirty filters can block airflow. Replacing them is a simple fix that improves efficiency. Check the vents: Make sure they’re open and not obstructed by furniture or debris

3. A/C Blowing Warm Air

Inspect the thermostat settings: Sometimes the fan is set to "on" instead of "auto," causing warm air to blow when the compressor isn’t running. Check refrigerant levels: Low refrigerant may require professional refilling. Look for signs of leaks around the unit.

4. Unusual Noises

Rattling or buzzing: This could indicate loose parts, debris, or electrical issues. Squealing: Worn belts or motor bearings may need to be serviced.

5. Water Leaks Around the Unit

Check the condensate drain line: If it’s clogged, water can back up and leak out. Clearing the line may resolve the issue. Inspect for frozen coils: This often results from poor airflow or low refrigerant and may need professional attention.
