Replacing an Air Conditioning Unit

Replacing an air conditioning unit can be a major investment for any homeowner. Depending on the climate of the area in which you live, you can be mighty dependent on your central air conditioning. Trying to cope with a system that seems to be half-stepping through the hottest months is never a good idea. The amount of energy wasted alone is reason enough to investigate replacing your dinosaur of a unit.

If you find you place a phone call to your local heating and cooling repair man every time the thermometer begins to climb, it may be time for a new system. In some areas, the summers are so relentlessly hot, you may find your system is running all the time. Of course, humidity can also account for the incessant operation of your cooling system. Hot and humid climes experience a good deal more usage and cycle through air conditioners more frequently than dryer climates.

To understand how your usage and need for your cooling system takes it's toll, you'll need to understand just how your system works and it is more complicated than Easter condo decorations. Your central air conditioning system is not just a cooling system, but also a dehumidifier as well. The process for cooling the air is much like the process your heating system goes through in the winter.

The warm, damp air is circulated through a system of return and supply duct work. Your supply ducts redistribute the cooled air throughout your home. As your cooled air becomes warm, it is circulated back through the ductwork to be re-cooled and redistributed.

There are two basic types of air conditioning systems for your home. The first one is referred to as a split system and is more often seen in homes. This system places the condenser and compressor outside of your home. Inside is your home is the evaporator coil. The evaporator typically is housed as part of the furnace, or heating system of your home. If you don't have an air conditioning unit in place, adding a split system is much more affordable if you already have a furnace system in place.

The package system is frequently used for commercial buildings, or small homes. Located on the roof or next to the building, this type of unit is all one package. These units can also be fitted with central heating elements, which will eliminate the need for an indoor furnace. The air is conversely heated or cooled by a series of pipes and fed into the home through ductwork.

Depending on the age of your unit, replacing your homes split system may require an entirely new unit. There have been changes made by governing agencies regarding refrigerants and energy efficiency and your heating and cooling repairman will know if your system requires total unit replacement. If your system isn't that old, but can't be repaired, you may be able to replace just the compressor. You'll need to have this performed by a licensed professional however, as the fittings may not be up to code and need replaced.

If you've had it awhile, you may benefit from replacing an air conditioning unit just to enjoy the energy savings. Specifications have changed in recent years and when you investigate the new air conditioning units available today you'll find the savings in cost of operating your cooling system will be remarkable. The energy saving guidelines that are in place today will reduce your energy consumption for air conditioning by as much as twenty to forty percent. If your system is ten years old or more, consider replacing it with a new, energy efficient model and it might just pay for itself.
