4 Common Reasons Why The Air Conditioner Is Not Cooling Down Your Home

Anyone who lives in a how environment knows that it is essential for the air conditioner inside a hope to operate properly during the sweltering summer months. Few things are more annoying on a super hot day than sweating inside your home and realizing that your air conditioner is not cooling your home down. There are several reasons why your home may not be cooling down-- some of the most common issues include:

Improper Thermostat Setting

When you crank down the temperature on your thermostat, you expect for your air conditioner to begin blasting cold air into your home. However, if your thermostat is not set properly, you won't find relief from the heat. When your home is not cooling down, the first thing you should check is your thermostat-- if it is set to "AUTO" instead of "COOL", that means the fan is running, but the actual air conditioner is not producing cold air. If this is the issue, switching your thermostat from "Auto" to "COOL" should fix the problem.

Old, Dirty Air Filter

Air filters are very easy for a homeowner to change, but it is not uncommon for people to forget to check them and buy a replacement. When an air filter becomes very dirty and filled with dirt, dust, and debris, it can be very difficult for the air conditioner to properly distribute cool air throughout your home. In addition, when the outside air conditioner unit is not getting enough air due to a dirty filter, the evaporator coil can freeze into a block of ice, which blocks cold air from flowing into your home.

Coolant Leak

Air conditioners use coolant to absorb the heat in the air and transform it into cold air. Coolant for an air conditioner does not get used up, so if the coolant level in your A/C is low, it means that you have a leak. If you suspect that you may have a coolant leak, avoid the area around your outside air conditioning unit and call an HVAC repair company. A certified HVAC technician can determine the source of the leak, make repairs, and then refill the coolant in your air conditioner.

Compressor Failure

The A/C compressor is arguably the most important component in an air conditioner, since it is responsible for continually circulating coolant in order to remove heat from hot air in order to create cold air. A compressor failure is a major issue; a compressor can be replaced, but a new compressor is extremely expensive, so when your air conditioner's compressor no longer works, you will most likely be recommended to replace your whole air conditioning unit.
