Air Conditioning Unit Not Cooling? 3 Possible Reasons Why

If your air conditioning unit is not cooling your home like it usually does, there are many things that can cause this to happen. Keep reading to learn of three possible reasons so you can get your air conditioning unit cooling properly.

Problems With The Thermostat

Start out by inspecting your thermostat. First, make sure it is on the cool setting and it is set at the correct temperature. If the thermostat is turned off and will not turn back on, it is time to replace it. This would be the reason why your air conditioning unit cannot keep the right temperature for your home. 

Newer thermostats are much better as there are different settings. For example, you can set the thermostat to the temperature you want it to be at night while you are sleeping, and have the thermostat automatically turn the temperature up at a certain time in the morning. You can also set the thermostat to turn off while you are at work, and then have the thermostat go to the right temperature at a certain time, such as an hour before you get home.

Problems With The Air Condenser

The problem could be with the air condenser that is inside the unit. It is common for the condenser to become dirty over time. If this is the case, an air conditioning repair technician can clean the air condenser for you, and this should fix your problem. The air condenser may also be bad and need to be repaired or replaced.

The air condenser may also be blocked. This is an easy fix as this is caused by something blocking the vent on the outside unit. Go outside and see if there is anything built up around the unit. This may be grass from when you mowed your lawn or weeds may be growing there. There may be leaves built up or other debris. Remove everything that you see and then try the air conditioner again to see if it works. 

Dirty Air Filter

All air conditioning units have air filters that need to be either cleaned or replaced every few months. How often this is will depend on many factors. For example, if someone in your home is a smoker or if you have pets in your home that shed, you will need to change out your filter more often. Also, if you have someone in your home that has bad allergies or respiratory problems you should change the filter more often.

If the air filter is dirty, this will block the air coming from your air conditioning unit, which means you will not get enough cool air inside your home. Fortunately, this is an easy fix as you can replace the air filter on your own. When purchasing one, just make sure you purchase the right size.
