What Can Occur From an Air Conditioning Malfunction

Summer may be winding down but we still have quite a few hot days ahead of us. When your air conditioning system is not working properly, it can become a big problem. You will undoubtedly want to solve the problem as quickly as possible. Some air conditioning problems are easier to solve than others. Common air conditioning problems include improper operation, insufficient maintenance, or faulty installation.


For air conditioners to work properly you will need to regularly have your air filters changed and the air conditioner coils checked to make sure they are not dirty. Allowing the coils and filters to become dirty will cause your air conditioner to not function properly and decrease its lifetime. The compressor fans will prematurely fail.

Refrigerant Leaks

If you are having problems with your refrigerant this could be caused by a number of issues. If the refrigerant is low this either means that the system is leaking or that when it was installed it was undercharged. Refrigerant levels should match the exact specifications of the manufacturer, so leaks should be dealt with immediately. You will need to contact a trained air conditioning repair technician to check for leaks, add the right amount of refrigerant, and check the repair.

Drainage Problems

Hot and humid weather can affect the way that your air conditioner functions. Humidity can cause the condensate drain to clog, which will not allow it to drain properly. Additionally, room air conditioners can be hindered from draining properly if they are not mounted level.

Sensor issues

There is a thermostat sensor on room air conditioners right behind the control panel. The thermostat evaluates the air temperature of the air that comes into contact with the evaporation coil. But if the sensor is accidentally displaced, this could cause the air conditioner to constantly remain or to behave erratically.

Electric control failure

When an air conditioner is constantly turning on or off this can cause the fan controls and the compressor to wear out more quickly. This is more common in an oversized system. If you think that you have a problem with terminals and wire corrosion you should contact a technician who can come out to check electrical connections.

These are some of the issues you may be having with your air conditioner. Contact Scott-Lee Heating today at (314) 200-0788 to schedule repair or maintenance services.
