Although there are potentially hundreds of reasons why your Miami home’s central air conditioner may need to be looked at by a certified contractor, there are a few reasons that are fairly common. Knowing what they are may help you to understand what a technician is referring to when they address the options for resolving the problem. Here are the 5 most common problems that may cause your AC unit to fail. Please review these considerations and determine whether you need to schedule an HVAC inspection.
- Wrong AC wiring
Shotty, haphazard or uncertified A/C wiring is risky and a possible fire hazard. Bad wiring often prevents the system from getting power or can short the circuit breaker.
- Your Air Conditioner is Low on refrigerant
Refrigerant (typically referred to as Freon) is the chemical that cools the air in your air conditioning system. Low refrigerant may imply a leak or problem with the refrigerant system. If your air conditioning system needs to be recharged with refrigerant, 90% of the time that means there is a leak. All refrigerant leaks should be detected and repaired. For news about the phase out of R-22 refrigerant in the United States, we suggest that you to visit the U.S. EPA website.
- Outside AC fan is not functioning
The fan on your outside AC unit is responsible for moving the heat from your Miami home to the outside air. If the fan on the outside unit doesn’t operate properly, 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.
- Outside air conditioner unit not functional
This typically indicates a significant reduction of power, contactor problems or even a bad thermostat.
- The coil is frozen
A frozen coil mainly indicates an issue with the airflow, such as restrictions caused by old air filters or obstructed return air ductwork. Frozen indoor coils could also be derived from low refrigerant.
Experts recommend that the most effective way for a Miami area homeowner to prevent these common problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be detected during routine maintenance tune-ups. For all these common issues, a professionally qualified, NATE-certified technician can efficiently analyze the problem area and apply the necessary repairs. Call or contact us today for an evaluation!
