Common Air Conditioning Problems

Air conditioning is a great comfort-provider, but can also create some headaches for owners. Air conditioners may not work efficiently, may not work as well as they should, and sometimes stop working altogether. Knowing some common air conditioning problems and options for solving these problems is beneficial for the appliance owner.

Size

Before having an air conditioner installed, make sure the contractor inspects the home size first. A frequent problem is that the system is too small or too large.

Installation

Improper installation of central air conditioning can result in poor air flow and leaking ducts.

Refrigerant

If the air conditioner does not work properly and is low on refrigerant, or Freon, it may have been undercharged when the system was installed. Otherwise the air conditioner may be leaking refrigerant.

Dirt

When filters and coils become dirty, the air conditioner will work poorly. In addition, the compressor or fans may break down.

Corrosion

Corrosion of terminals and wires is a common air conditioning problem.

Outside Fan

If the outside fan stops running, the compressor may overheat and become damaged.

Frozen Coil

A frozen coil usually is a sign of air flow problems, such as a dirty filter or blocked duct work. It also can be caused by low refrigerant.
