Troubleshooting Air Conditioner Issues

During the hot summer months, there is nothing worse than when the air conditioner stops working properly. This is enough to change an entire home from a haven into a completely uncomfortable and unbearable space.

That is exactly why it is important to know how to troubleshoot your home’s air conditioning unit. While some of these issues you can correct on your own, there are other problems where it is necessary to bring in the trained professionals of an HVAC company. However, knowing what is going on and what is causing the problem is going to help speed the repair process.

Not Running at All

If the air conditioner is not running at all, first check the power on the thermostat. It is possible the device is not set to “cool” or that the battery in the thermostat has died.

By changing the battery, you will be able to stay on top of the situation. If the unit still doesn’t run, then there is likely a problem with the air conditioner itself. This means you need to check your breaker box and make sure the air conditioner did not trip a fuse.

Sometimes when an air conditioner first comes on during the summertime, it can trip a fuse. This usually happens during the night (for reasons unknown), but by resetting the circuit in the breaker box, the air conditioner almost always fires up again.

Running, But No Cold Air

One problem that is rather frustrating is when the unit is running, but there isn’t any cold air coming. Again, the first thing to check is the thermostat, as it might simply be on the fan setting. Outside of this, a common problem is when the air filter has not been changed in a while. A dirty filter can prevent the cold air from reaching the rest of my house.

If you’ve checked the fuse and the filter, and your unit is still not working properly, be sure to call a professional HVAC contractor. Here at Airtron, we’re standing by in case of air conditioning emergency.
