Minisplit: Leave it on or turn it off?
Very well insulated home. Nudura ICF Walls (2.5″ EPS x 6″ concrete x 2.5″ EPS) with R-40 roof, 3″ slab insulation, R7 windows, Zone 4 climate at 5,000 feet elevation. Under 800 sqft of conditioned space and I have a 1 ton ductless Mitsubishi mini-split heat pump (23 SEER).
At 7am the interior temp is 68F and by 6PM the interior temp is 74F. Outside temps in the 92F-98F during the day with a blazing desert sun. .
Should I leave the unit off and turn it back on around 6PM to cool the house down or just leave it on all day? Which is more efficient?
