Installing an Air Conditioning System in an Older Home

If you are renovating your older home, consider adding an air conditioning unit to help make the space both attractive and comfortable.

Some older neighborhoods around the country, such as Chevy Chase, Maryland, were built in the early 1900s, about the same time as Willis Carrier, the inventor of modern air conditioning, was just beginning to develop the air conditioning systems that most resemble contemporary models. At the time, though, these lovely homes were not designed for cooling; rather they were outfitted with radiator heat or a boiler to keep their occupants warm during the cold winters.

Veteran Marylanders can tell you, however, that summers in Washington, D.C. and Montgomery County, Maryland are notorious for their extreme heat and humidity.

Depending on the size and design of the house, homeowners have several options.

One such option would be the installation of an air handler with ductwork in the attic.  Some larger homes require a two zone installation, one unit in the attic and another in the basement.  In the event that space is limited in the attic and/or the basement, a closet might do just fine.

Some companies, such as Mitsubishi, boast a line of high efficiency ductless air conditioning and heat pump units. Please note that all of these options will require an outdoor condensing unit.
