Reasons Your AC Isn’t Cooling Your Home


An air conditioner is an essential appliance in most homes these days. Heat during summer has been especially intolerable over the last few years. It’s times like these when we rely on our trusty air conditioners to get us through the day.

Given our dependency on them, most of us become concerned when we sense something is wrong with our air conditioners. A common problem many people face is that their AC seems to be on, but isn’t cooling their home.

There are many reasons this could be occurring. We’ll go through some of the most common causes here to help you better understand the problem. As to what you can do about it: call a professional.

Possible Reasons

Here’s a list of potential reasons why your AC isn’t cooling your home:

A Faulty Compressor or Thermostat

The thermostat on your AC takes a reading of the temperature in the room, then determines if it is sufficiently cool. If the temperature is higher than the temperature requested, it signals the compressor to turn on and begin the process of cooling the air.

A damaged thermostat could be the cause of your AC issues, whether it be a problem with the thermostat’s calibration or an issue with the connection between the thermostat and the cooling system.

If you find that the thermostat works fine, then the next suspect is a fault in the compressor itself. Causes of a busted compressor include a defect in the wiring, the start capacitor, or the compressor.

It isn’t a good idea to address any of these issues yourself. A licensed professional has years of experience and specialist training to manage this task expediently. If you try to DIY, it might make the situation worse.

Low Refrigerant Levels

If your AC is leaking refrigerant, it may trigger the low-coolant safety mechanism in your unit. This exists because refrigerants can be detrimental to your health. If your refrigerant level is low it means there is a leak in the system requiring professional repairs.

A Damaged Fan

One of the most visible indicators of a problem with your AC is a fan that isn’t working. If your AC is not cooling your home, check to see if the fan on the outdoor unit is moving. If it isn’t, then your system won’t be able to do its job. If the fan isn’t operating it means that your system won’t be able to release the heat it pulls out of your home.
