Why is my AC running but not blowing air?

If your air handler is running but not blowing air, there are two likely scenarios; either a broken AC blower belt or an issue with the motor itself. If the air handler is humming or buzzing, but not making the mechanical sounds of a motor running, you’re most likely talking about an issue with the motor itself.

What to check if your AC is not cooling?

Look at the condenser If you’re experiencing AC not cooling while the system is powered on, you could have a clogged or blocked coil. Unfortunately, a wide variety of debris can find its way into this equipment, including grass, dirt, and other contaminants.

Why is there no cold air coming out of my vents?

Make sure the fan setting is set to “auto” not “on”, which will cause your AC to blow air even if it’s not being cooled. 2) Check your air filter— If the air coming out of the supply vents is weak and not very cool, check to see if the air filter is dirty and change it if necessary.

Why is there no air coming from vents?

Vents Blockage If you feel no air is blowing from vents in your house, vent blockage is most likely to be the issue. You might be blocking your air vents unknowingly; a piece of furniture might be in front and blocking the airflow, or you might have closed some vents on a chilly day and forgotten to open them again.

How do I know if my AC blower motor is bad?

  1. AC Fan Doesn’t Start. Even though you have the AC turned on, the fan does not start.
  2. AC Fan Doesn’t Stop.
  3. Slow Rotating Blades.
  4. Outside Fan Blades Are Still.
  5. Rattling, Humming, and Buzzing Noises.

Why you should never turn your AC off?

If you leave your air conditioner off during the day, indoor temperatures will continually rise while you’re gone. By the time you get back, temperatures will be so high that your air conditioner will consume more energy cooling down your home than it would if you left your system on all day.

Can a dirty air filter cause the air conditioner not to cool?

As a result of the buildup, a dirty filter will also cause poor cold airflow in your air conditioning system. That cold air will be trapped inside your air conditioner, causing ice to form on its coils. Once that happens, your air conditioner will freeze up and become inoperable.
