Central Air Conditioner Not Cooling Properly During Summer

Is your central air conditioner not cooling your home?

Perhaps it’s blowing warm or hot air.

There are a variety of things that could cause your central air conditioner not to cool your home correctly.

Let’s look at five common reasons why your central air conditioner might not be cooling correctly.

Dirty Air Filter

When your air filter is dirty, the amount of air that can blow over your evaporator coils is restricted. When this happens, much of the warm air that your air conditioner pulls from your home’s air will not be cooled.

Refrigerant Leak

Refrigerant is what flows through your air conditioner coils and moves the heat from inside your home to the outside condenser unit. If your system has a refrigerant leak, it will not adequately move heat out of your house. 

Thermostat Setting

Does your central air conditioner blow out cool air sometimes and lukewarm air other times?

Then the fan setting may be set to “ON,” which runs the fan 24/7, even when the air isn’t being cooled.

Be sure to check that the thermostat is set to cool.

Leak In The Ductwork

A leak in the ductwork is a little harder to diagnose but could be costing you both cold air and money.

A leak in the ductwork means that the cold air is filtered out into the walls before it reaches the vents. 

Older Unit

When a central air conditioner reaches the end of its working life, it will not be able to cool your home like it used to. This is why it’s essential to replace your system when it is no longer able to perform effectively.

It’s incredibly frustrating when your central air conditioner doesn’t do the one thing it’s specifically designed to do.
