5 reasons your AC is running but not cooling your home

Here are some of the most common reasons your AC unit isn’t cooling your home properly (even if it’s turned on):

  • There’s something wrong with your thermostat
  • Dirty air filters can cause your AC to run but not cool
  • If your AC is leaking water
  • Your AC unit is too big or small for your home
  • Blocked vents can also prevent your AC from cooling properly

Reason #1 — There’s something wrong with your thermostat

If your AC isn’t cooling your living space as it should, the first thing you should check is the thermostat. If it’s not set to “cool,” then the unit won’t turn on. If the thermostat is set properly but the AC still isn’t cooling, you may need to clean or replace the air filter.

If the AC is still not cooling, it’s best to call a technician for diagnosis and repair.

Reason #2 — Dirty air filters can cause your AC to run but not cool

Any HVAC technician will tell you that a dirty air filter can lead to wide variety of issues.

In some cases, a dirty air filter forces AC to run but not cool. This is because the unit has to work harder to draw air through the filter, using up more energy in the process.

As a result, your AC may not be able to reach the desired temperature, causing your home to feel stuffy and warm.

Several things can make your AC’s air filter dirty; some examples include:

  • Airborne contaminants
  • Poor ventilation
  • Not changing the filter regularly
  • Using the wrong type of filter
  • Not cleaning the vents
  • Having too many pets

So if you notice that your AC isn’t running as efficiently as usual, be sure to check the air filter. A simple cleaning may be all that’s needed to get your AC unit back up and running.

Reason #3 — If your AC is leaking water

If your air conditioner is leaking water, it could be the reason why it’s not cooling as effectively as it should. While a small amount of water condensation is normal, if you notice a large puddle of water around your AC unit, that’s a sign that something is wrong.

One possible cause of this problem is that the drain line is blocked. This line helps to remove water from the unit, and if it becomes clogged, the water has nowhere to go. Another possibility is that the evaporator coils are frozen. These coils help to remove heat from the air, and if they’re frozen over, they can’t do their job properly.

Reason #4 — Your AC unit is too big or small for your home

When it comes to air conditioners, size matters. An AC that is too big or too small for your home won’t be able to cool it properly, even if it’s turned on.

That’s because an AC has to be properly sized in order for it to work efficiently. A unit that is too big will cool the space too quickly and then shut off before the humidity levels have a chance to drop. This can leave your home feeling damp and muggy.

On the other hand, an AC unit that’s too small can potentially overwork itself without reaching the desired temperature.

Reason #5 — Blocked vents can also prevent your AC from cooling properly

One of the most common causes of poor AC performance is blocked vents. When airflow is restricted, it puts stress on the system and prevents it from cooling properly.

Vents can become blocked by furniture, dust, or even pet hair, so it’s important to regularly check them and keep them clear.
