Normally, air conditioning systems are rated in tons.

Air conditioners are rated in three ways, by B.T.U.'s, Tons of Refrigeration, or by Horsepower.
One Ton of Refrigeration removes the amount of heat needed to melt one ton of ice in 24 hours.
One Ton of Refrigeration can remove 12,000 B.T.U.'s of heat in one hour.
The B.T.U. is the amount of heat needed to raise 1 lb. of pure water 1 deg F.

Welcome to our forums!

You need to be much more specific with your question.

I would take a wild guess you are wanting to replace your furnace and want to know what to get.......is this so?
If you are thinking about replacing your heating system this would be the time to have a heat loss/gain calculation done because heating systems were often grossly oversized in the old days and new ones work more efficiently if properly sized.

For us to offer better info we need to know all the details about your home relating to its size, type and relative age.
We also need to know all about the heating system you have, its heating capacity, type of fuel, cooling capacity if you have a/c and a general idea about duct-work if you have a forced air furnace.
