Working Backwards:Normally we would first
calculate our Heat Load and then ask, “What is our best choice for
heating and cooling?”
Tonight we are impressed with the 25 SEER , 12,000 btu
Heating and Cooling unit from Fujitsu. We know it’s output.
Can we modify the building envelope to get the load down to where our preferred unit
will do the job?
