As many as eighty percent of the new homes being built in the U.S. are constructed with central ac units installed. Central air just makes sense, as it keeps the indoor temperatures comfortable while filtering and dehumidifying the air. This is very nice for men and women who suffer from allergies or asthma. Fortunately, central air conditioning units can be installed in preexisting homes, also.

When shopping around for central air-conditioning units, there are lots of things to consider. One is that the size of the home you’ll be cooling. Ac units come in various sizes, so it’s important to pick the most efficient size for your cooling job you’ve got in mind. If the device is too big, it won’t dehumidify properly. To ascertain the right size, consult a contractor. They ought to have access to some calculation procedure referred to as “Manual J” which can help you pick a size.

Another important consideration in central air conditioning units is a rating called the SEER rating. These letters stand for Seasonal Energy Efficiency Ratio. New air conditioners are needed to have a score of 13. A unit that has been installed over twenty years ago likely has a score of only 7 or 8.

By replacing old inefficient air conditioners with new central ac units, you can save yourself a whole lot of cash in heating costs. It is estimated that increasing the SEER rating from 11.5 to 13 could help save you over $500 each year in cooling costs. Also, start looking for “Scroll(tm) technology” when choosing a compressor for the most current in efficiency.

Another thing to look for in central air conditioning units is the “Energy Star.” This is a certification given to brand new appliances that use less energy compared to other new models. Needless to say, they use a lot less than equivalent units which are a variety of years old.

When installing central ac units, the positioning of the outdoor unit may make a big difference. When it is surrounded by plant or is under a deck, the air won’t have the ability to flow freely in and out of it. Not only that, the units may be noisy. Do not install it near an area in which you like to enjoy eating or visiting outdoors, including a patio or deck.
