7 Common AC Repairs
By: Monika
While there are hundreds of possible reasons for an AC repairs system to falter or break down, seven of them tend to lead the pack in frequency.
If you spot any of these leading A/C system “troublemakers,” contact us right away before the situation grows worse. Especially since there’s a slim to zero chance it will get better – at least not on its own.
-
Frozen inside coil
A frozen coil often indicates a problem with airflow, such as restrictions caused by dirty air filters or a blocked return air duct. Frozen indoor coils also can be caused by low refrigerant levels.
-
Outside unit not functional
This typically indicates a lack of power, contactor problems or even a faulty thermostat.
-
Outside fan is not working
The outside fan is responsible for transferring heat from inside to outside your home. If the outside fan stops working, proper heat transfer is not taking place and the air conditioning compressor may overheat and trip the safety overload. Worse yet, it may cause internal damage to the compressor.
-
Low refrigerant
Refrigerant is the chemical that cools the air. Low refrigerant may indicate a leak or problem with the system.
-
Faulty wiring
Improper, haphazard, or uncertified A/C wiring is a potential fire hazard. Faulty wiring also prevents the system from getting power or can trip the circuit breaker.
-
Dirty Condenser Coil
Condenser coils are located outside with the compressor so they can become dirty due to the elements. They can usually be cleaned with a water hose once a year, but if they get too dirty, an HVAC technician will have to clean them with a chemical cleaner.
-
Worn Contactor
In an AC unit, there are contactors for the compressor, the blower motor, and the condenser fan motor. They make an electrical connection that starts the motors and compressor. If there’s arcing and pitting on the contactor, it becomes difficult for electric current to start the motors.
