The air conditioning sysytem is exposed to harsh weather elements and the system works the hardest when the weather is the hottest. Not many mechanical systems can hold up under these conditions and not without the proper service. An air conditioning service professional should inspect the cooling system annually before the cooling season begins. This annual check-up will find seasonal problems before the weather makes life miserable for a few days. A check-up can also save money by making the AC repair and adjustments before they become costly to repair. AC Maintenance is important to the proper functioning of the unit.

Before the cooling season begins turn on the central air and set the thermostat for 65 degrees. If the room temperature has not changed in 20 minutes, there is a problem that needs professional diagnosis.

There may be any one or a combination of problems that the homeowner should call a service professional to check out. For instance, the unit may be low on Freon, the motor may be burned out, the compressor may not be working, or the thermostat may not be functioning properly.

These are AC repairs that the homeowner should not attempt to make. Working on an air conditioning unit requires considerable training and experience. It is always tempting to avoid an AC repair call but the units in service today are high tech and more damage can be done by putting off that call to the service professional.

Other problems can arise including the air conditioner evaporator coils and condenser collecting dirt and the dirt reduces air flow. The dirt also acts as coil insulation reducing the capability of the coil to retain heat. The condensate pump may be faulty. The service professional will also check the coil fins to clear any blockage which can constrict air flow through the coil. AC Maintenance can prevent many of these problems.

If the air conditioning unit is more than 10 years old and requires frequent service calls a service professional should check the unit's efficiency. Problems with high humidity in the house may be the result of an inefficient air conditioning unit. If some rooms seem to be at the wrong temperature the fault may be an inefficient unit.

Other problems can occur like a clogged condensate drain which will have an adverse effect on reducing humidity and may result also in a backup of water into the house.

An efficient air conditioning system is an energy saver and will make the occupants of the house comfortable.
