Why is My AC Not Cold?

When the temperature outside starts climbing, it’s no surprise that you’re going to heavily rely on your air conditioner to save you from the heat. However, if your AC is blowing anything but cold air, you have a major problem on your hands. If your AC is not cold, these might be some of the reasons why.

Your thermostat isn’t set right.

You should have your thermostat set to “auto“ so it only blows cold air when it runs. If it’s set to “on,” the fan will just constantly run even if the air it’s blowing isn’t cold.

You should also make sure your thermostat is set to the right temperature. If it’s not set to a low enough temperature, your AC won’t blow cold air. It’s as simple as that.

Your air filter is dirty.

If you aren’t regularly cleaning or replacing your systems air filters, you end up limiting the airflow. Not only will this prevent your AC from cooling air to your ideal temperature, but it could also freeze the evaporator coil and prevent air from getting to any part of your system.

Your unit is low on refrigerant.

Refrigerant is the solution that helps create cold air within your cooling system. If your unit has a refrigerant leak or the refrigerant isn’t charged properly, your AC won’t be able to produce cold air.

The easiest way to make sure your refrigerant is at the right level is to have your unit inspected by an HVAC professional.

Your outside unit is dirty.

If it’s not blocked from the elements, your outside condenser unit can become dirty or surrounded by debris, such as leaves and branches. Since this limits the airflow to the unit, check it every so often to make sure it’s not being blocked by anything.
