If your air conditioning system is not cooling your home like it normally does, there are many things that can cause this to happen. Below are three of these things so you can get your home cool again.
One thing that can cause your air conditioning system not to cool is if it is low on coolant. Coolant is also commonly called Freon. When your air conditioner starts blowing air the air is warm. The coolant is what cools down the air before it reaches your home.
It can be common for the coolant levels to become low over time if your air conditioning system is older. You can simply add more coolant to take care of this problem. If your air conditioning system is not old, then you have some type of leak going on. This is when you need to hire an HVAC contractor to repair your system.
Problem with Fan Blades
The fan blades inside your exterior air conditioning system need to be in good condition in order to spin properly. If the fan does not spin, then the air will not be moved well enough to reach the inside of your home.
You can look at the fan blades on your own through the vent in the exterior unit. If you see the fan blades are bent, there are special combs that are made to straighten them out. If you see the fan blades are in very bad condition, such as some are broken, then you need to have the fan replaced by a professional.
Problems with Thermostat
The thermostat inside your home could also be the cause of your air conditioning system not cooling. First, check the thermostat to see if it is set to cool and that the temperature is set right. If so, turn the thermostat off and then back on. See if you hear the air conditioning system run. If not, then you may have a problem with the thermostat. If so, replacing the thermostat would likely repair this problem.
If you have an old thermostat then a new one would be much better. This is because newer thermostats are much more energy-efficient and this can save you money on your energy bills. You can set the thermostat to turn off during the day while you are not home and then set it to turn back on an hour or so before you get home so you can walk into a cool or warm home.
