My AC unit is running. However, it’s not cooling
Why is my AC running but not cooling? If your AC isn’t cooling, several potential issues could be causing the problem.
Dirty Air Filters
Clogged filters can restrict airflow, reducing your AC’s efficiency. This can make it harder for your system to cool your home. AC Dave Heating and Air recommends changing your filters at least twice a year.
Thermostat Issues
Set your thermostat correctly to ensure your AC cools properly. According to the US Dept. of Energy, the recommended temperature for your thermostat is 78 degrees Fahrenheit when at home. Additionally, raise it to 85 degrees Fahrenheit or higher for better energy savings while sleeping or away.
Refrigerant Leaks
Consequently, refrigerant leaks lower refrigerant levels, impairing your AC’s cooling ability. Since refrigerants can be hazardous, a professional should diagnose and fix this issue.
Blocked Condenser Unit
Furthermore, debris, dirt, or plants blocking the outdoor condenser unit will interfere with the cooling process. To maintain optimal cooling, keep the area around the condenser clear.
Faulty Compressor
For one thing, the compressor is a key part of the AC system. If it’s not working properly, as a result, the AC will not cool efficiently or at all. In particular, a malfunctioning compressor can cause several problems. Here are some signs that may indicate your compressor is failing:
- Warm air blowing through your vents.
- Unusual noises such as rattling, clunking, or hissing.
- Frequent circuit breaker trips are caused by the compressor drawing too much power.
- AC won’t start, which could be caused by a refrigerant leak.
- Vibrations or shaking.
- Higher energy bills.
Electrical Issues
Problems with wiring, circuits, or other electrical components could disrupt the AC’s operation. As mentioned above, these issues could stem from rodent activity or a faulty compressor. If in doubt, get your licensed HVAC technician out to check your unit.
Undersized Unit
If your AC unit is too small for its cooling space, it might struggle to maintain the desired temperature. If you suspect this, ask your licensed HVAC technician to come out and give you a free bid for a larger unit.
Frozen Evaporator Coils
If the evaporator coils freeze up, the cooling will reduce or stop. This is due to airflow issues or low refrigerant levels.
