Common AC Repairs You Should Know About

Your air conditioning unit is a crucial part of your home, especially during the hot summer months. However, like any other appliance, it may encounter issues that require repairs. Understanding common AC repairs can help you identify problems early and prevent costly breakdowns. 

Refrigerant Leaks

One of the most common AC repairs is refrigerant leaks. If your air conditioner is low on refrigerant, it will not be able to cool your home effectively. Signs of a refrigerant leak include reduced cooling capacity, hissing sounds from the unit, and ice buildup on the evaporator coil. If you think you have a refrigerant leak, it is essential to call a professional HVAC technician to find and repair the leak promptly.

Faulty Capacitors

Capacitors play a crucial role in starting the motors in your air conditioning unit. Over time, capacitors can wear out or fail, causing your AC unit to have trouble starting or running efficiently. Signs of faulty capacitors include clicking noises when turning on the unit or the compressor not turning on at all. A trained technician can replace faulty capacitors to ensure your AC unit runs smoothly.

Clogged Air Filters

Clogged air filters are another common issue that can lead to poor airflow and reduced cooling efficiency in your home. Dirty filters restrict airflow and force your AC unit to work harder to cool your home, leading to increased energy bills and potential system damage. Regularly changing or cleaning your air filters every couple of months can prevent this issue from occurring.

Frozen Evaporator Coils

Frozen evaporator coils are often caused by restricted airflow or low refrigerant levels in your AC unit. When evaporator coils freeze over, they cannot effectively absorb heat from inside your home, resulting in warm air blowing out of the vents instead of cold air. To prevent frozen evaporator coils, ensure proper airflow by keeping vents unobstructed and scheduling regular maintenance checks with an HVAC professional.

Electrical Issues

Electrical problems such as faulty wiring or blown fuses can cause your AC unit to malfunction or stop working altogether. Signs of electrical issues include tripped circuit breakers, burning smells coming from the unit, or flickering lights when the AC turns on. It is crucial to address electrical problems promptly, as they can pose a fire hazard if left unresolved.

Understanding common AC repairs can help you maintain a comfortable and efficient cooling system in your home. By being aware of signs indicating potential issues with your air conditioning unit, you can address them early and prevent costly breakdowns in the future.
