In order to get the most out of your central air conditioner, it is important to do routine maintenance. Keeping your unit clean and operating properly will not only extend the length of its life, but it will also run more cost effectively. There are many potential issues or problems your system may face as it ages, but not all of them require a certified technician to address them. Fortunately, there are many things you can do on your own to ensure your air conditioner is running at its best and keeping your home comfortable. Here are central air conditioner troubleshooting ideas to help you learn what you can do if you ever face common, easy-to-fix problems.
Air Conditioner Runs but Doesn’t Cool
If your air conditioner is running but not cooling, the most likely problem is that the unit is not clean. Therefore, this should be the first thing you check.
- Turn off the power to the unit using the disconnect panel on the wall next to it, and turn off the air conditioner’s circuit at the main electrical panel.
- Make sure nothing is blocking air flow to the unit, such as bushes.
- Remove the cover and grilles that cover the compressor.
- Clear out any debris, such as sticks and leaves.
- Using a hose, spray debris out of the fins. Be careful not to get any of the electrical wiring wet.
You can test to see if your air conditioner runs properly after cleaning it by turning the thermostat off, resetting the power at the disconnect and main panel, and then waiting five minutes before setting the thermostat to “on.” After a few minutes, feel the two pipes that connect the condenser to the air handler. One should be warm, the other cool.
Air Conditioner Runs but Doesn’t Blow Air
If your air conditioner is running and not blowing air, there is probably an issue with the belt. To fix it, turn off the power to the furnace and the gas. Then, remove the door to gain access to the blower. If the belt is broken, find the number stamped on it. You can use this number to find a replacement belt. Slip the belt on the smaller pulley first. Rotate the pulley by hand until the belt is secure on the larger pulley. If the belt is too tight, you can adjust the motor mount to add more slack. Check your manual to see if the motor mounts require lubrication.
Air Conditioner Doesn’t Turn On
If your air conditioner isn’t turning on, make sure the thermostat is set to “cool” and the temperature is set below the room temperature. Here are some other things to try:
- Check the main electrical panel for a tripped breaker or a blown fuse.
- Check the furnace power switch.
- Check to see if the outdoor condenser’s power switch is turned on.
- Make sure the disconnect next to the compressor isn’t shut off.
