What Makes Your Home Cool? The Elements of Your Home Air Conditioning System

For many homeowners their air conditioning system works by turning it on and ensuring the thermostat is set lower than the ambient room temperature. While that may be basically true your central air conditioning system is comprised of a variety or parts that when working together will provide excellent service. It is when one of the parts requires air conditioning maintenance that you might need to know what to look for.

Main Elements of a Home Cooling System

The major portion of your central air conditioner is divided into two parts: outdoors and indoors. In the outside section, are your compressor, condenser coil and fan. Your compressor is the heart of your system and it is responsible for circulating the refrigerant, commonly called by its brand name Freon. It is comprised of a closed system that goes between the condenser and evaporator coils. Scroll type compressors are costlier but are more efficient and operate quieter than the optional reciprocating compressors.

Your condenser coil is essentially a loop of pipe packed with refrigerant that disperses the heat from the heated gas refrigerant and turns it into a liquid form. Excess heat that is generated escapes to the outdoors. You will also have a fan that pushes the air through the coil to help dispel the heat. Having the fan outside also reduces the amount of noise in the home.

Inside your home you will have an evaporator coil which is another coil of tubing filled with compressed refrigerant. This coil removes moisture and heat from the air and allows the refrigerant to turn back into a gas form. An air handling unit, often the same fan that moves heat from your furnace into the ductwork, is also located indoors as are the air filters.

The filters are designed to capture air particles to prevent them from scattering around the house. The filters also play an important role to keep the air conditioning system moving air efficiently and helping to maintain its continued operation. A majority of the small issues with air conditioners is usually attributable to clogged filters.

When your air conditioner is operating normally, it will create a great deal of condensation which drips in the form of water into a drain system. Water is usually carried away from the unit to the pan by a pipe and into a pan that should also have a drain hole in it. This system will need periodic attention to make sure the pan’s drain hole isn’t plugged. If the pan fills with water it can run over and drip onto the floor. This is especially damaging if the drain pan is located in a ceiling.

Keeping Your Home Cool and Utility Costs Low

Other than regular filter changes and keeping your drain lines open, any major issues with your air conditioning should be looked at by a qualified air conditioning maintenance professional. All of the unit’s parts need to work in tandem in order to work properly. A system that functions as it was designed will keep your house cool and help keep your utility costs low.
