Why is my AC running but not cooling?

Updated: Mar 16

When the days start getting longer, it means one thing: warm weather is soon to follow! For people who can't get enough warm weather, this could mean increased time spent outdoors. However, having a properly functioning AC system running in your home is necessary for your families comfortability. If you've recently noticed that your air conditioning is running but not cooling your home, this could be a result of one (or more) of these common issues.

Dirty Or Clogged Filters

Most homes have indoor and outdoor air conditioning units, which means two possible zones need to have their filters checked. If either of these filters is dirty or clogged, it will restrict airflow from the outside. When running, an AC unit moves air both in and out of the system to keep coolant flowing freely and the inside units cool. If there's restricted airflow, it can cause the system to run but not cool your home due to lack of sufficient cooling.

Malfunctioning Thermostat

Another reason your system may be running but not cooling is due to a malfunctioning thermostat. Your thermostat is the "brain center" that controls your HVAC system, so it may set the temperature too high if it isn't accurately reading your indoor temperature. That is a common issue, as a malfunctioning thermostat can result in higher energy bills and unnecessary strain on your AC system.

AC Compressor Is Running, But The Fan Isn't

Another possible reason your AC isn't cooling is that the fan is not running. First, check to ensure the fan switch. The fan switch could be in an outside wall near the air handler. This particular fan switch controls the flow of cool air throughout your house. If this specific fan switch isn't "on," the AC system runs. However, the treated air isn't getting circulated throughout the home, so it can't provide the cooling benefits as it should if functioning correctly.

An AC Wiring Issue

Another potential reason your AC is running but not cooling could be a result of a faulty wiring connection. If the wiring going into or coming out of your thermostat is loose, this could be the cause. If you're not sure how to inspect it or if your wiring appears to be in good shape, call an AC professional for help with troubleshooting and repairs. Wiring and electrical problems are severe and should get addressed without delay.
