An air conditioning system is comprised of major and minor parts. Each serves its own unique purpose. Some issues may result in minor AC repair needs. However, if major parts such as AC compressors or motors fail, homeowners might be facing more complex repairs or possibly need to replace them. The following points identify common causes of air conditioning systems not cooling.

Malfunctioned Compressor

The compressor is a critical part of every AC system. It also happens to be one that is expensive to replace. HVAC professionals can inspect compressors to determine if they are in decent enough condition to warrant an AC repair. If repairing the malfunctioned compressor is not an option, they will use a few factors to determine if an AC repair that involves compressor replacement is a good idea. Systems that are aged might be better suited for upgrading to a new AC system due to the high cost of buying a new compressor. An air conditioning repair might be cheaper than a new system, and the final decision will be up to the homeowner.

Refrigerant Leak

HVAC technicians check refrigerant levels when they perform maintenance. If the levels are low, they add refrigerant. They also take time to inspect the system for leaks. Refrigerant leaks are considered emergency AC repairs because if a system runs out of refrigerant severe damage may occur.

Leaky Ductwork

Ductwork can last for many years, but at some point, it will need to be replaced. Leaks in ductwork allow cool air to escape. This can cause energy bills to be higher, and it might also cause AC systems to work harder to cool homes. This overworking is bound to lead to system failure and may require replacing the ductwork and making other AC repairs. 

Dirty Condenser Unit 

The condenser unit is located outside of the home. Many homeowners do not realize that they need to protect these units from damage. They can invest in condenser covers or use everyday materials such as tarp to cover the units. Unprotected units may get dirt, grass clippings, leaves, twigs, and rocks inside of them. The units may also be negatively impacted by vegetation growing beside them. If ants are common in the area, they might also form anthills around the unit. These acts of nature can interfere with condenser units being able to perform their function of dissipating heat. 

An HVAC contractor is a good resource to use to learn more about air conditioning repairs. They can inspect systems to determine what type of repair is needed. The professionals can also help homeowners to understand the importance of routine and how it can reduce or eliminate  AC repair service requests.
