Top 5 Common Air Cconditioning Unit Problems

Although there may be hundreds of factors why your home’s central air conditioner may need to be looked at by a certified technician, many of these reasons are fairly common. Check out our list of the top 5 list of most common problems that may cause your air conditioning system to break down. 1. Faulty wiring Shoddy, haphazard or uncertified A/C wiring is risky and a possible fire hazard. Bad wiring can prevent the system from getting power or can trip the circuit breaker. 2. Low refrigerant Refrigerant is the chemical that cools the air within your air conditioning system. Reduced levels of refrigerant could 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 suggests there is a leak. All refrigerant leaks should be located and repaired. 3. Outside fan is not working The outside fan is responsible for conveying the heat from your home to the outside air. If the fan on the outside unit doesn’t perform correctly, proper heat transfer cannot take place and the air conditioning compressor may overheat and trip the safety overload. Worse yet, it may cause internal damage to the compressor. 4. Outside unit not functional This usually indicates a lack of power, contactor problems or even a faulty thermostat. 5. The coil is frozen A frozen coil often indicates an issue with the airflow, such as restrictions caused by filthy air filters or obstructed return air ductwork. Frozen indoor coils could also be the result of low refrigerant. The most effective way to prevent these expected problems is by participating in a preventive maintenance program. Bad wiring, low refrigerant and airflow problems can be discovered during routine maintenance tune-ups. For all these common issues, a professionally qualified, technician can promptly analyze the problem area and implement the necessary repairs.
