I'm getting ready to replace the furnace in my home. It has 962 squre feet with a finished full basement. What size furnace should I use.

What size do you have? Did it do the job? Much more info would be needed if there was a correct rule of thumb to go by,, but,, you should get about 3 quotes from local contracters,, your house need to be looked at for all the necessary problems to be considered

wmproop is correct. You may not even need as large of a funace if it did a good job, if you are going from an 80 percent eff or less, to a 90 plus you may save money on a lower BTU input with higher BTU output than your old funace. Like wmproop said, have the pros look at it for you and give you some options.
