The size (cooling capacity) of your air conditioner is determined by the amount of Btu (British thermal unit) and the Tonnage (12.000 Btu = 1 Ton). What amount of Btu and Tonnage should your air conditioner have in order to properly cool your home? Although we, at Kobie Complete, use a complex formula and factor in many details to determine the exact amount of Btu your new air conditioner should have, we provide you with this free online Btu and Tonnage calculator (also known as load calculation) to give you a rough estimate. Just fill in your home’s square footage, the number of occupants and windows in the form below.
