Selecting Right Size of Air Conditioners Is Vital Picking the right size air conditioner requires some math calculation
Choosing the right size of unit or system will effectively keep you and your household comfort. Air conditioners that are too big use more electrical power and leave the air in your residence with excess humidity. Air conditioning unit that are too small do not cool your the home of a comfy temperature level. Picking the right size a/c requires some standard math and simply a few minutes of your time. Measure the square footage of the space that you’ll air condition. Use a tape measure to determine the length and width of the room. Compose these dimensions on your paper. If the space is not square or rectangular, divide the room into areas composed of squares and triangles and take those dimensions. Determine the square footage of the room. For a square or rectangular space, multiply the length by the width. If your room is some other shape, discover the square footage of the triangular areas by multiplying 0.5 x length x width and sum each of the square and triangular areas to determine the total square footage of the space. Figure out the square footage of each room of your house if you are buying a central air conditioning system. Reviewing your property tax statement or contacting your county auditor’s workplace is an additional way to discover the overall square footage of your home. Don’t consist of locations, like the basement, that won’t be cooled. Identify the cooling ability needed for the space or your home. Cooling ability for space a/c and central air conditioning systems is determined in British Thermal Systems (BTUs) per hour. The United States Department of Energy Energy Star website offers these standards for BTUs per square footage: 100 approximately 300 sq. feet: 5,000 to 7,000 BTU 300 approximately 550 sq. feet: 8,000 to 12,000 BTU 550 up to 1,000 sq. feet: 14,000 to 18,000 BTU 1,000 approximately 1,200 sq. feet: 21,000 to 24,000 BTU 1,500 up to 2,000 sq. feet: 30,000 BTU 2,000 up to 2,500 sq. feet: 34,000 BTU.
