High Efficiency Central Air & Cooling Systems
We install the most efficient central air conditioning and cooling systems
The value of a cooling system is easy to confirm when a house is put up for sale: Houses with central air conditioning systems demand a higher price than those without them.
Today the term "cooling system" usually means a central air conditioning system - conditioned air that is distributed to the living space through a ductwork system.
However, there are other factors involved in keeping a house cool during hot weather that also need to be considered. We'll discuss these below.
Building envelope improvements play a major role in cooling system efficiency
It takes more than a well-functioning air conditioning system to keep a house cool during hot weather.
All of the following elements are important, "passive cooling" details. They don't consume electricity. They don't require maintenance, and (with the exception of windows) they never wear out. They DO however, help reduce cooling costs by limiting heat gain.
Attic insulation: Most interior heat gain during hot weather comes through the roof and attic. Direct solar gain can heat roof shingles to temperatures as high as 140 degrees Fahrenheit. The roof passes its heat into the attic space by conduction and convection. Adding more attic insulation can help slow the movement of heat towards the cooler interior.
Radiant barriers: While attic insulation slows heat movement by conduction, a radiant barrier reflects heat energy back toward its source, just like the reflective shields used to protect car interiors from overheating. In an unfinished attic, a radiant barrier is usually installed in the form of a reflective sheet that is stapled to the underside of attic rafters.
High-performance windows & doors: Windows and glazed doors that have an ENERGY STAR® rating, have insulated (double or triple-pane) glass and "low-e" films in the airspace between glass panes. The low-e film or coating reflects some solar radiation back toward the outside, helping limit the solar gain inside the home.
Natural Solutions: Simply opening windows to get the cooling benefit of breezes can sometimes be a no-cost substitute for mechanical air conditioning. Shading: Trees and other vegetation can keep interior temperatures more comfortable by shading parts of the house from direct sunlight. Shading can also be provided in the form of porch roofs, awnings and overhangs that keep direct sunlight from hitting sides of the house.
