Btu and Tonnage Calculator

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.

Dear Ted Steele, On October 23, we had a Lennox system installed. We are extremely satisfied with it. Brad and Robert had both told us that the old Carrier was dying. We were anxious about the trouble, time and mess it was going to be. The handler closet is in the middle hallway - the route goes through the laundry area and the garage. There are bedrooms on both sides - our place is very small. We were not looking forward to the carnage! Tony and John showed up (on a rainy day) and assured all would be well. We left and when we returned, they were finishing up. House, garage, and even the yard around the unit were neat and clean - totally fantastic! Brad came to help change out something at the end - it was a long day for all of them! Brad also returned to change out "stuff" in the fuse box. Everyone involved did a great job. They retained their humor and spirit throughout this long, hard process. The results are amazing. We had a very bad install previously - with with pipes and wires exploding out of the bulkhead! We have the condensate drain that needs a pump! The closet was a mess to look at! It's all changed - everything is sealed and neat. All of these men were very polite, professional and neat. Tony, especially, is very verbal and chop-chop and gives you confidence that the job is going to go well! He and John are a great team! We have been with Kobie for a long time - this is the second house - and we are still happy! P.S. I forgot to mention Leah - she is always very helpful. We've already received our rebate check! Augusta B.
