Central air conditioners have two separate components: the condenser and the evaporator. The condenser unit for air conditioner is usually located outside the house on a concrete slab. The evaporator coil is mounted in the plenum or main duct junction above the furnace.

Basic central heating and cooling information.

Most types of central air conditioners are connected to a home’s forced-air distribution system. Thus, the same blower, motor and ductwork used for heating are used to distribute cool air from the air conditioning unit. During the air conditioning process, hot air inside the house flows to the furnace through the return-air duct. The hot air is moved by the blower across the cooled evaporator coil in the plenum and is then delivered through ducts to cool the entire home. When the air conditioner operates but the home doesn’t cool, the problem is probably in the distribution system.

how to service air conditionerCommon air conditioner problems

One of the most common air conditioning problems is incorrect operation. If your air conditioner is on, be sure to close your home’s windows and outside doors.

Other very often problems with existing air conditioners result from improper air conditioner installation service and inadequate maintenance. Improper installation of a central air conditioner can result in low airflow and leaky ducts. Many times, the refrigerant charge does not match the manufacturer’s specifications. If proper refrigerant charging kit is not performed during installation, the performance and efficiency of the entire heating and cooling units is impaired.

INADEQUATE MAINTENANCE

If you struggle from problems like air conditioning coils freezing because of allowing your filters and air conditioning coils to become dirty, the air conditioner will not work properly, and the compressor or fans are likely to fail prematurely.

REFRIGERANT LEAKS
If your superior heating and cooling system is low on refrigerant, either it was undercharged at installation or it leaks. If it leaks, simply adding refrigerant is not a solution. A trained technician should fix any leak, make sure the home air conditioning repair is properly done and the system is working, then charge the system with the correct amount of refrigerant. Remember that the performance and efficiency of your A C system is greatest when the refrigerant charge exactly matches the manufacturer’s requirements, and is neither undercharged nor overcharged. Refrigerant leaks can also be harmful to the environment.
