Central Air

Few things can improve your quality of life quite like relaxing in the cool comfort of an air-conditioned home. Central air is an absolute lifesaver in the middle of a July heat wave, of course, but the benefits of great climate control go beyond cooling. A good air conditioner will keep air circulating in your home and help everyone breathe easier, not to mention cutting down on humidity and reducing fire hazards. Moreover, with a top-notch air conditioner, you can save money on utility bills and increase the value of your home.

How Your Central Air Conditioner Works

Air conditioners have come a long way since their invention in the early twentieth century, but they still use the same basic cooling cycle. At the evaporator coil, refrigerant chemicals absorb heat from your home and become gaseous. The air conditioner then pumps the refrigerant vapor to the condenser coil, where a special pump called a compressor forces it to become liquid again. This phase change releases the stored heat, transferring it away from your home. The refrigerant chemicals then return to the evaporator coil to repeat the cycle.


Central air conditioners use a specialized system of supply and return ducts to circulate cool air throughout your home, providing efficient and effective cooling to the entire house. The main upshot is a consistent, comfortable temperature throughout the home–moreover, you won’t have to carry heavy window units all over the house at the start and end of the cooling season.

Whether you’re building a new home and need a way to keep it cool or you’re looking to replace an aging system, you’ll need professional installation to get your new central air conditioner up and running. Every installation project should start with a load calculation–after all, improper sizing is one of the biggest causes of efficiency and maintenance issues down the road. Once you have a properly sized system in hand, you’ll need a highly qualified technician to make sure it meets the manufacturer’s specifications.

Like all machines, air conditioners do wear down over time. The average central air conditioner is built to last up to 10 years, but to get a full decade of use out of yours, you’ll need to have it maintained. Professional seasonal maintenance not only extends the lifespan of your system but also saves you money every month by maximizing energy efficiency. Of course, even a well-maintained system can run into trouble, and you’ll need a qualified repair technician to take care of that problem.
