It’s been a hot summer so far, with record temperatures being set often – and we’re only halfway through the summer! The hottest months are still to come. If your central air conditioning system is blowing warm air, the time to get it fixed is right now.

Several different problems could be behind why your AC isn’t producing cold air, and fortunately, you can do some troubleshooting before calling us to come and visit. Here are three common issues to check:

Incorrect thermostat settings

This may seem obvious, but it’s pretty common to turn your furnace on instead of your air conditioner accidentally. It’s the best place to start. Begin by checking your thermostat settings and its batteries – the problem could be as simple as changing the system’s mode or merely flipping a switch.

Your AC unit outside is dirty

While your indoor unit is responsible for absorbing heat from your living space, the outdoor unit is responsible for releasing it. Your system relies on the joint operation of both your indoor and outdoor units. If the outdoor unit won’t start or isn’t working correctly, the warm inside air won’t be released into the outside atmosphere. As a result, you’ll feel warm air from the vents inside your home. Check your outdoor unit from time to time, to be sure that it’s free from dirt and debris.

A dirty air filter

A clogged or dirty air filter won’t make your AC blow warm air, but it can cause less air to flow through your system. Reduced airflow can cause you to experience hot and cold spots in areas of your home.

When was the last time you checked your air filter? It’s probably been longer than that since you replaced it. If you can’t remember how long it’s been, we highly recommend that you turn off your system and clean or replace your filter.

If you’ve checked all of these potential problem areas and you’re still experiencing warm air, give us a call and we’ll be happy to help you keep your home – and your family – comfortable this summer.
