Why Is Your AC Blowing Warm Air?

a fanThere are few things more frustrating than coming in from the sweltering heat outside for some relief only to find that your AC is blowing out warm air. While the problem may be simple to solve, knowing what some of the more serious issues could be as well will help you get your system back to normal operation more quickly. Here are some of the most common issues that cause your AC to blow warm air.

Your Thermostat Isn’t Set To Cool

While it may seem like the obvious first thing to check, many people forget to change their settings from heat to cool between seasons, and since this is the easiest and fastest solution, it’s worth checking first. Make sure your thermostat is set to cool your home, and if you have it set to “auto” or your system’s equivalent, move it to “cool” to see if that fixes the issue. Auto settings sometimes cause your interior systems to blow air even if the condenser outside isn’t on.

You Have An Airflow Problem

A very common issue that could be causing your AC to blow warm air is restricted airflow. If air doesn’t move fully through your system as intended, cooling and heating efficiency can be severely reduced. Make sure your vents and intakes are clean and free from obstruction, and if your filters haven’t been replaced recently, consider replacing or cleaning them. More serious airflow issues like leaky ducts should be inspected and corrected by professionals.

There’s An Issue With Your Condenser

The condenser unit outside is what moves the refrigerant in your system around, so problems here can cause your AC to blow warm air. First, clear all weeds and plants around your unit. Next, make sure the unit isn’t visually clogged with dirt or leaves. Lastly, check to see if the electrical circuit for your condenser was tripped. This can mean a major problem with your unit, so contact a professional if this is the case.

You Have A Refrigerant Leak

Refrigerant isn’t used up in your system, so if the levels are low it means you have a leak somewhere. This will also require help from a professional, so schedule maintenance as soon as possible to get your system back up and running properly.
