Blog Title: How do you size an air conditioner?
How are the sizing capacities of heating and cooling systems measured?
Category: Ac Compressor Post By: EDITH WHEELER (Monroe, MI), 10/02/2013

Heating and cooling systems sizing is based on B.T.U.H. (British Thermal Units Per Hour). Air Conditioning and Heat Pumps are also rated in tonnage. 12,000 BTUH equals one (1) ton. Residential systems can range from 1 to 5 tons.
