We're building a new home that's been appraised for 4059 sq ft. We decided to have an inspector go out to the house and do what they do. During the inspection, they brought up that the installed unit is undersized. It's a Lennox 14ACX-060 16 SEER 5 ton external compressor.
The inspector is claiming that we should have closer to an 8 ton unit. I requested the Manual J, but am still pretty lost. I've been doing a lot of reading today and am pretty convinced that the calculation is correct... But then again... I'm just going off of what I've read on the internet.
I just want to make sure the unit is properly sized for our house. I don't want to end up stuck with a unit that's too small. Along with the manual J, I stuck a picture of the floor plan blueprint.
