Why is My Air Conditioner Not Working?

Serving Families Throughout Dallas

Are you worried that your air conditioner isn’t working? A professional can help you diagnose and repair the issue. To help give you peace of mind in the meantime, we have five reasons why this may be happening to you.

5 Reasons Your Air Conditioner May Not Be Working

1. Your thermostat is set to “ON” instead of “AUTO.”

If you notice both cool are and lukewarm air coming from your AC system, the fan setting may be set to “ON,” which just runs the fan 24/7 — even when the air isn’t being cooled.

2. You haven’t changed your air filters.

This may be an obvious one for our veteran homeowners out there, but we have to say it anyway — you’re supposed to change your air filters every one to three months! If you don’t, a dirty air filter can cause several issues. Your system will struggle to circulate cool air around your home to reach your desired temperature. Or, the evaporator coil will freeze and turn into a block of ice, blocking the air from cooling your home.

3. Your outdoor unit isn’t clean.

The condenser at the outdoor unit is responsible for releasing the heat that the indoor unit absorbed from your home’s air. But, this can’t happen if it’s filled with dirt, debris, and leaves from your backyard! Spray your outdoor unit with a hose on a gentle setting (a high setting can bend the fins and damage your system).

4. Your condenser fan is broken.

If the condenser fan motor is broken, then the outdoor unit’s fan won’t be able to dissipate heat and your AC won’t cool your house.

5. You have low refrigerant.

Your HVAC is not like a car that needs to be fueled consistently with gas. The only reason it would have low refrigerant is from a leak. When you don’t have enough refrigerant, your AC can’t absorb enough heat to cool the air. So, if you end up hearing bubbling or hissing sounds or see ice buildup on the refrigerant line at the outside unit, it’s time to call a professional.
