Identifying and Repairing Problems with Your Air Conditioning System

Your A/C system is a complex apparatus that, when working properly, fill your entire home with cool, comfortable air. When it glitches, however, the challenge is to find which part of the complex and elaborate machinery is the culprit.

Identifying the issue requires a trained, and experienced air conditioning professional. The service experts at Big John's Heating, Ventilation, Air Conditioning are just the right technicians for the job.

Air Conditioning Repair

Common Causes of a Malfunctioning Air Conditioning System

Many factors can cause your A/C to malfunction. Some of the more common ones include:

Lack of refrigerant in the system: A lack of sufficient refrigerant will cause the system to work harder to produce cold air. Air conditioning systems don’t consume or burn refrigerant, so if the level is low, it’s the result of a leak or not being sufficiently filled at the time of installation or previous service.
Dirt and grime on the condenser coil: Dust, dirt, and grime can collect and get caked onto your air conditioner’s condenser coil (one of the most important, but fragile, parts of the system). When the condenser coil is covered with dirt, it becomes difficult for the refrigerant inside the coil to condense to its liquid form, making the system far less efficient.
Clogged air conditioning drain tube: When the surrounding warm air meets the cold evaporator coils in, an AC system, condensation occurs naturally. The water accumulates into a drip pan to be drained away from the system. If that line becomes blocked, the water can back up into the system, covering the evaporator coil with ice, impeding the efficient functioning of the entire system.
Defective sensors or electrical controls: The major components (the compressor and fan) in the air conditioning system depend upon electrical current to work. If a damaged or defective electrical control disrupts the flow of power, the air conditioning system will no longer function properly. The system also must rely on sensors inside the thermostat to command it when to activate and when to shut it off. A faulty thermostat sensor could cause the air conditioning system to constantly run or never turn on at all.
