Why Is My AC Running But Not Cooling?

We all dread the day that something goes wrong with the AC, especially in the middle of a Texas summer. When you can hear your AC running but no cold air coming out of the vents, there’s some kind of problem. Let’s go through a troubleshooting checklist to help you figure out why your AC isn’t cooling.

Check Your Thermostat Settings

Before you panic, go look at your thermostat settings. Sometimes we can accidentally change them while setting the thermostat. The thermostat should be set to AUTO, not ON, for the best results. It should also be set to COOL. If the settings were incorrect, give the system a few minutes to begin working properly before moving on to the next potential problem.

Is the filter dirty?

It’s really easy to forget about your air conditioner’s filter, but neglecting it can cause a lot of problems, including restricting airflow and allowing debris to build up throughout the system. Check your filter, and replace it if it’s dirty. Set a reminder to replace it again in a couple of months while you’re at it, so you don’t forget.

The new filter will allow conditioned air to flow more freely and might resolve the problem. You should begin feeling the cooler air within an hour if it works.

The Circuit Breaker is Tripped

Did you know that most AC systems have a separate circuit for the indoor and outdoor units? If the outdoor unit’s circuit breaker is tripped, the AC will continue to run, but the air will be warm because the outdoor unit isn’t working to get rid of the heat. Check that none of the breakers in your electrical panel are tripped if you continue to have problems.

It’s Time to Call a Professional

Past the troubleshooting tips listed above, the best thing you can do is call a trustworthy HVAC company for AC repair. Your AC is likely having issues due to a refrigerant leak or other serious issue, so an experienced technician is the best person for the job.
