What Can You Do If Your Air Conditioner Does Not Cool?

Posted on: 27 April 2020

As a homeowner, you know the importance of keeping your HVAC system in good working order. Over time, you may begin to notice that your air conditioner is not outputting cool air. The lack of cold air from the air conditioner can be due to a number of reasons. The problem may be something you can easily take care of yourself, or you could have a major malfunction that needs professional attention. Here are some things you can check yourself before you call your HVAC contractor to hopefully restore the cool air.

Is the Condenser Clean?

The condenser is the large unit outside your home. This component is one of the most important parts of an HVAC system. If it is not functioning, you will not have cold air. If you notice that the fan is not operating when you have the air conditioner setting on, you will need to call your contractor to have the problem evaluated. However, if the fan is running, make sure there is not buildup around the system. Dirt, leaves, and other debris can collect around the unit and prevent the air flow that is necessary for the unit to operate. Carefully clean any debris you see collected on the condenser to see if that helps the issue.

Is the Thermostat Working?

Over time, a thermostat can stop working. The thermostat is the control center for an HVAC system. If your HVAC cannot get the message from the thermostat, it will not signal the system to cycle and you will not have cool air. Some thermostats use a battery and will just need a simple battery change to fix the problem. However, a thermostat can wear out and need replaced. This is a rather easy job if you are familiar with this type of job. If you are not comfortable exchanging your thermostat, you can have your HVAC contractor do the job for you.

Is There Power Connection?

An HVAC system needs electricity to work, even if you have a gas-powered system. The HVAC will have its own set of breakers in your home's electrical breaker box. If even one of the breakers has tripped, it will prevent the HVAC from cycling. If you aren't sure, you can flip all the breakers for the system off then on again. Some breakers may look like they are in the on position but are actually tripped. Taking a moment to flip the breakers will help you determine if the breaker is the problem.

These are a few things you can try to help cool your air. If none of these solutions work, be sure to call your HVAC contractor for an AC repair.
