The 4 Most Common Central Air Conditioner Problems

Annual Maintenance is the Key To Staying Cool

Crestwood air conditioner maintenance

With the hot, humid weather right around the corner in the Crestwood area, now is a good time to have your central air conditioner maintained. Most of the air conditioner problems we see every day are the result of lack of maintenance and not having the AC unit regularly inspected.

1. AC Refrigerant Leaks

A central air conditioner should not lose coolant during normal operation. There are a couple of reasons an air conditioner may be low on refrigerant – either it was not sufficiently charged when it was installed, or it has developed a leak. Your HVAC technician will look for leaks in the system and refill the unit with refrigerant if needed. The amount of refrigerant added to the unit must match the manufacturer's recommended amount to ensure optimal cooling performance. If a leak is found it's best to find the cause of the leak and make repairs before adding more refrigerant.

2. Clogged Furnace Air Filters

An air filter should be replaced monthly, or as recommended by the filter manufacturer. When filters become dirty and clogged the AC unit must work harder, and parts such as the compressor or fans are likely to wear out prematurely.

3. Dirty AC Coils

Evan a small amount of dirt accumulating on coils can significantly reduce the cooling performance of your air conditioner. AC coils should be cleaned to prevent the accumulation of dirt and debris. Before performing any maintenance always be sure to shut off the power supply to the unit.  Gently vacuum the fins and coil to avoid bending the metal. Never use a power washer to clean an air conditioner. Keep the area around the air conditioner free of tree branches and bushes to keep debris from falling on the unit.

4. Air Conditioner Electrical Component Failure

Compressor and fan controls will wear out over time, especially when the air conditioner turns on and off frequently. If your noticing that the AC is cycling on and off more frequently, or is running much longer than usual, give us a call to inspect the unit. Corrosion of wires and terminals is another common problem in many systems, so the electrical connections and contacts should be inspected annually during AC system maintenance.

By regularly maintaining your air conditioner you can keep your air conditioner running as efficiently as possible, while also saving money on unexpected breakdowns and repairs.
