Central Air Troubleshooting Tips
Why Your AC Isn’t Cooling and What You Can Do
When your central air conditioning system isn’t cooling , there could be a variety of culprits behind the issue. At Oehlert Bros., we’re always here for you. But, it makes sense that you might not want to call in the professionals right away. Read on for some troubleshooting steps you can follow to try to identify and possibly resolve the problem.
Assess your Central AC with DIY Steps
We know that time is of the essence when you’re sweltering in eastern Pennsylvania, and your AC isn’t working. Get started investigating what’s wrong with these DIY steps:
- Check the thermostat: Make sure the thermostat is set to the “cool” setting and that the temperature is set lower than the current room temperature. Ensure the thermostat has power and fresh batteries, if it operates on battery power.
- Verify the power supply: Check that the air conditioner is receiving power. If it’s not turning on at all, check the circuit breaker or fuse box to see if a circuit has tripped or a fuse has blown.
- Inspect the air filters: Dirty or obstructed air filters can restrict airflow and cause the system to work inefficiently or shut down. Check and replace the air filters if they are dirty.
- Clear debris around the outdoor unit: If you have a central air conditioning system with an outdoor unit, ensure it is free of debris like leaves, grass, or branches. Blocked airflow can affect the system’s performance.
- Listen for unusual sounds: If you hear strange noises coming from the central air conditioner, it could indicate a mechanical issue. Grinding, banging, or squealing sounds may require professional attention.
- Check for ice buildup: If you see ice forming on the indoor or outdoor unit, turn off the system and let it thaw. Ice buildup can occur due to airflow problems or refrigerant issues.
- Inspect the condensate drain line: A clogged condensate drain line can cause water leakage, which may trigger safety mechanisms to shut down the system. Clean the drain line if it’s clogged.
- Examine the ductwork: Check the ductwork for any visible damage or disconnected sections that could be causing air leaks.
- Look for refrigerant leaks: Low refrigerant levels can prevent the system from cooling properly. If you suspect a refrigerant leak, you’ll need to contact a professional HVAC technician to handle this issue safely.
- Reset the system: Sometimes, a system reset can help resolve minor issues. Turn off the power to the air conditioner, wait a few minutes, and then turn it back on.
