When your air conditioner is running perfectly you hardly pay any attention to it. It runs in the background according to the thermostat settings, and your home feels comfortable. However, a broken AC is going to lead to troubleshooting the problem, repairs, and potential replacement. Here are three problems you could run into with central air conditioning.
Your air conditioner will have a condenser located outside of your home with a fan in it. The entire device helps change refrigerant into a gas, which cools the condenser coil and creates cold air. It's an essential part of the entire system, and you will not have cold air without it. A part that can break on the condenser is the fan, which can cause the condenser to overheat and fail. It is more likely that the entire unit will shut down because of safety features. Any failed fan needs to be fixed so that the system can run smoothly.
In addition, there is a blower fan located inside your home. Once the refrigerant cool's the coils inside the blower unit, the fan pushes the cold air into your home. This is another fan that can easily fail from use since it is a moving part.
Freezing Condenser Coil
Another part that can have problems is the condenser coil. The coil itself can actually freeze up, which will prevent the refrigerant from traveling through the system. Even though the coil is frozen, you may think that it still helps produce cold air, but this is incorrect. A condenser coil works by extracting heat from the air as it passes over the coil, which makes the air cool. Frozen coils mean that the refrigerant can't cycle the way it should. The frozen coil will actually cause the air conditioning system to produce warm air in your home.
Another problem that can affect the refrigerant within the air condition is a leak in the refrigerant lines. Even a small leak can cause the pressure within the lines to drop below the required levels, which can cause the entire system to not work efficiently. You'll need to have the lines inspected to find and repair the leak, then refill the air conditioner with the proper amount of refrigerant.
If you need help troubleshooting or repairing any type of problem related to your air conditioner, reach out to a local HVAC technician for assistance.
