I have a question about sizing ductless for cooling
I’m building a 1,043 sq ft, 1 and 1/2 story cottage. I had independent heating and cooling load calculations done. I’m going with two Mitsubishi Hyper heats, one up and one down.
For downstairs, the cooling load is 13,778 BTUh and the heating load is 1,1524 BTUh. The energy consultant says his calculations are conservative, for the strict purpose of not oversizing. I would like to go with the 12K BTU Hyperheat for downstairs, but it’s only rated at 12K for cooling. Would the slightly undersized 12K be OK for this application? The downstairs includes living area, kitchen, bath and a bedroom in 630 sq. ft.
