Experiencing air conditioner problems on a hot, muggy day could signal the need to call an HVAC contractor, but before reaching for the phone, try these solutions first. You may be able to get it running again, restoring your comfort quickly.
- The A/C isn’t cooling adequately. Try turning the thermostat down a few degrees. If it’s slow to cool down and doesn’t reach a comfortable temperature, the evaporator coil in the air handler could be excessively dirty, caused by running the system with a dirty air filter. When this situation only happens on exceptionally hot days, your system could be too small for your home. Lighten the cooling load by curtailing heat-producing activities, closing the window coverings and making sure all exterior doors and windows are shut.
- The outdoor condenser doesn’t turn on. Check the thermostat to verify that it’s working. If not, you may need to replace it. You may also need to check the circuit breaker for the air conditioner, which may have tripped. Another possibility: the fuse in the outdoor condenser may have burned out. A problem with the compressor can prevent the system from turning the system on, which also requires the help of an HVAC professional.
- The system runs but doesn’t cool. The two most common air conditioner problems that cause a lack of cooling include a blocked or dirty condenser and low refrigerant levels. Check the condenser, remove any debris that surrounds it and hose off the fins and coil using a light spray with the hose. Low refrigerant can inhibit cooling and may even freeze the evaporator coil, stopping the cooling process. Only licensed HVAC contractors can check the level and add more.
- The air conditioner turns on and off quickly. This can indicate a blocked condenser or a dirty evaporator coil. Clean the condenser and the indoor coil if it’s accessible. If not, contact an HVAC professional.
