Is Your Central AC Unit Not Blowing Out Cold Air?

Air conditioning is our best friend throughout Georgia’s hot summer months. But there’s nothing worse than when your AC unit all of a sudden breaks, and your central AC isn’t blowing out cold air. Now what?

Don’t panic! There’s a couple different reasons as to why your AC unit is not blowing out cold air. Your broken AC issue may be a fixable, at-home solution, or you may need to contact your local air conditioning company.

AC not blowing cold air? Find out if you can fix your AC unit yourself, or if you need to contact a 24/7 air conditioning repair technician.

AC Not Blowing Cold Air- Can I Fix it Myself?

Problem #1: Your air filter needs to be changed.

If your AC is failing to blow out cold air, you may need to change your air filter. Air filters are a central part of your HVAC unit. All of the air handled through your HVAC system must be passed through your air filter first.

Your air filter catches debris, dust, dander, mold, etc. Over time, your air filter becomes more dense. If you don’t regularly change your air filter, the air cannot pass through.

When Should I Change My Air Filter?

We recommend that you change your air filter every 1.5-2 months. If you have pets and children, you may need to change it more often.

Failing to change your air filter can cause extensive damage to your AC system. It’s important to regularly change your air filter to ensure the longevity of your system, prevent unnecessary damage, and ensure your air is clean and healthy. Air filters are the first line of defense against pollen, dust, and other allergens that can potentially cause severe health damage.

How to Fix: Change your air filter regularly.

Problem #2: Your thermostat is set to “ON”.

Do you feel like your air sometimes blows out cold, and other times, blows out lukewarm? You may need to change your fan setting on your thermostat. Thermostats have settings for “on” and “auto”.

Should I set my thermostat fan setting to “AUTO” or “ON”?

The straight answer: set your thermostat fan setting to “auto”. Setting your thermostat to “auto” will only turn the fan on when the cool air is running. If you set your thermostat to “on”, you air conditioner is running 24/7, without actually cooling the air. If your home AC is not blowing out cold air, make sure your thermostat fan-setting is to “auto”.

How to Fix: Change your thermostat fan setting to “AUTO”.

Problem #3: Clean your outside central AC unit.

It’s important to let your central AC unit breathe! Debris can get trapped in/around your outside central AC unit and can cause your unit to work less efficiently. In addition to your air not getting cold, your energy bills could also be higher. Go outside and do a check of the area around your unit. Clean any weeds around it, as well.

How to Fix: Clear dirt, branches, and leaves around your AC unit to let it breathe.
