How many ton condenser do you need for 2000ft house?

Answer 1

Probably around a 4 ton, however. Properly sizing an a/c cannot be assumed. It depends on the size of the ductwork (most important) , and how many windows, exposure to sun and exposure to elements, insulation, the actual materials of construction and basement no basement. The proper way residentially would be to have someone due a manual J calculation. This will give you your Ideal cooling, then you need to look at the existing equipment and make sure that the blowers and ductwork handle the Ideal airflow and tonnage. i.e. if you had a 4 ton a/c on 2.5 tons of ductwork the coil will freeze. Any reputable dealer is going to be able to do this for you. Let's make another assumption. "It's been working fine." so the company puts the same size system in, and you maintain 74 degrees f even though its running excessively, do you know what's going on. No most people don't until the right service guy come in an starts pointing out problems. Then the consumer either thinks that they are being sold, or feel hurt that they have been taken.

A manual J calculation is the right correct and only way
