4 of the Most Common Central Air Conditioner Problems


Many air conditioner problems we see are simply the result of poor maintenance. Other problems are just a result of wear and tear. Here are some of the most common air conditioner problems we see.

1. Refrigerant Leaks

There are two reasons air conditioners are low on refrigerant, either the unit was not adequately filled when it was installed, or it has developed a leak. Your technician will look for and fix any leaks in the system and refill the unit with refrigerant. It’s important that the amount of refrigerant match the manufacturer’s recommended amount to ensure optimal cooling performance.

2. Clogged Furnace Air Filters

This simple maintenance task is often overlooked by homeowners. When air filters become clogged the system works harder, and is subject to premature wear.

3. Dirty AC Coils

The coils on the outside of the home should be cleaned to prevent the accumulation of dirt and debris.

4. Air Conditioner Electrical Component Failure

Compressor and fan controls are subject to wear over time, especially when the air conditioner turns on and off frequently. 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 will keep your air conditioner running as efficiently as possible, while saving money on unexpected breakdowns and repairs.
