If your home A/C unit requires frequent repairs or fails to cool your home sufficiently, it could mean it is time for a replacement. Before you decide to upgrade to a new unit, you may want to learn what is causing the issues. Here are the main reasons older air conditioners fail.



1. Failure of the Electrical Controls

There are several electrical connections and mechanical parts inside your air conditioner that can break down after years of use. It is also possible for the electrical wiring to become corroded over time, which can cause problems with the connections. The electrical controls that turn the fan and compressor on and off may fail due to simple wear and tear. If you have an air conditioner that is too large for your home, it may turn on and off frequently, which can make the controls wear out sooner.

2. Leaking of Refrigerant

Another common issue with an older home A/C unit is coolant leakage. A specific amount of refrigerant is required for your equipment to function properly, but over time the level can drop when small leaks develop. When your air conditioner runs, the unit changes temperature and vibrates, which can loosen the seals and cause leaks. Damage from environmental factors can also cause issues. If you suspect a problem with the coolant, it is best to contact a technician who can check for leaks and refill the refrigerant to the proper level.

3. Insufficient Maintenance

Over time, an air conditioner can lose its ability to cool when the air filters become clogged and debris builds up on the cooling coils. When this happens, the unit needs to run more often to cool the air, which can lead to additional wear and tear on the compressor and fan. A maintenance technician can check and clean your air conditioner to increase its longevity.
