What is tonnage? 

In Air conditioning Tonnage = BTU, there are 12,000 btu's in one ton of air conditioning. If your home requires 3.5 tons of air conditioning you will require a 42,000 BTU system.

Wondering what tonnage your home or business requires to properly heat or cool? At GallettAir Inc. we provide a service that insures that the system for your home or business is properly sized.  We calculate your home with a Manual J8 program.  In the past, it was common practice to utilize only square footage in sizing.  Today's new energy standards require companies to factor in exposures and the type of construction of the building including window sizes and type, insulation (R) factors, ceiling heights, lighting as well as age of the building or home. At GallettAir Inc. we will put in writing that your home or building has been properly sized which will qualify for manufacturer and utility rebates.  Most importantly you will be insured a properly sized efficient operating system that will provide cost effective comfort for many years.  If you are a homeowner or a builder in need of system sizing, we provide this service for a minimal cost.  Just call our toll free number at 1-800-427-2653 or drop off your plans. We can tell you exactly what the heating and cooling load requirements are for your home or business.
