Common Causes of Air Conditioner Failure

During the summer weather, your air conditioner becomes the most important part of your home. It is crucial that your air conditioner is working at optimal performance in order to keep the summer heat out of your home. Yet with any type of electronic appliance, your air conditioner can be prone to breaking down or failure. The cause of your air conditioner failure can be to different issues without and around your cooling system. Here is a list of some causes that are known to cause the failure of your air conditioner in Marietta.

Coil Problems

Two coils that cause air conditioner failure are the evaporator coil and condenser coil. Evaporator coils are filled with a solution known as refrigerant. Refrigerant helps the coil remove and absorb surrounding heat and humidity from the air. These coils need warm air surrounding them in order to function properly. If the air isn’t warm enough, ice can form around the coil, which prevents warm air from being cooled down.

Condenser coils are located in the outdoor component of your system. If the condenser coil gets dirty or covered in grime, it reduces the coil’s ability to transfer heat. As a result, your air conditioner has to work harder to cool down your home, which wears out the AC faster and contributes to additional breakdowns and failures.

Holes and Leaks

Cracks, openings, and leaks in the pipes and ventilation can all cause air conditioner failure. Your unit’s refrigerant runs through a special pipe system to the evaporator coil. Leaks in these pipes will affect your air conditioner’s ability to cool down your home. Fixing the issue can be expensive since you are not only replacing the refrigerant, but also replacing and repairing the leaky pipes.

Your ducts deliver cool air throughout your home. Any holes or leaks in these ducts prevent cool air from reaching you. This reduces your air conditioner’s performance efficiency and can raise your electric bill. Your unit’s drains are what allow moisture that is created during the cooling process to flow out of the systems into the drain pipes of your house. If these drains become clogged, water builds up within your system. Excess water can not only damage your unit, but it can also damage your walls, ceilings, and furniture, while promoting the growth of mold.

Temperature Regulation Issues

Other components help regulate the temperature in your home as well as the unit itself. One of these components are the cooling fans. One fan helps to blow indoor air over the evaporator coils to cool it down while a second fan blows air over the condenser coils to remove hot air from your house. Fan failure can often be due to issues with the fan’s motor, lack of lubrication, worn belts, or dirty fan blades. Fan failure can cause damage to the compressor, which results in needing to replace your air conditioner.

Another component that regulates temperature is your thermostat. Whether you use a traditional dial or digital program thermostat, air conditioner failure can occur if the thermostat is incorrectly calibrated. Usually, replacing or recalibrating your thermostat can fix the issue. An improperly calibrated thermostat can prevent your air conditioner from properly cooling down your house or prevent it from functioning at all.
