Troubleshooting Tips for Common AC System Issues
When your air conditioner gives out in the middle of the summer, it’s not necessarily a cause for panic. Some issues will require the attention of a trained professional, but others may be addressed by the homeowner. Here are a few AC system troubleshooting tips you can try before you reach for the phone.
Is the Air Conditioner Not Kicking On?
First make sure the main control is set on “cool” and the temperature setting is below that of the room temperature. You can also check for a blown fuse or tripped breaker, replacing the fuse or resetting the breaker if needed. The main power switch and the outdoor condenser power switch should both be in the “on” positions.
If that doesn’t solve the issue, turn off the AC’s power and check the thermostat. Remove the cover and unscrew the Y terminal wire, then turn on the power. Hold the wire by its insulation and touch the bare end to the R terminal, holding it for a couple of minutes. If the AC comes on, this means the thermostat isn’t working properly and should be replaced.
If the AC system is running but it’s not cooling as it should, it could be because the coolant needs recharging. This is a task a technician must perform. Otherwise, try cleaning the condenser coil in the outdoor unit or the evaporator coil in the indoor unit. A dirty condenser or evaporator may also cause the system to cycle on and off repeatedly. Clean coils with coil cleanser. The air filter might also need changing to ensure proper airflow.
A blocked condensate drain may cause inadequate cooling or pooling of water near the air conditioner. Locate the condensate drain near the AC’s indoor unit and try using a drain snake.
