I a hoping that one of the engineers here can help. In the continuing saga of central air estimates, we had an estimate from a contractor on a mini split ductless system. Gross was 16k, net of tax rebates and whatnot is 14k. Uh, not. However, they can install a system that will cool the lower floor of the house (where we spend most of our time in the hottest part of the day) for $3.5k after rebates/incentives. This system would be an 18,000 BTU system with a SEER rating of 19. The alternative is two wall units. One would be a 12,000 BTU unit at about 11 EER and the other would be a 5,000 BTU unit that operates less frequently with an EER of 8.
Electricity is quite expensive here (north of $.20/kwh), so I am trying to figure out if the ductless system is worth doing downstairs if it consumes a lot less power. I cannot figure out how to estimate the power consumption of these two alternatives. Anyone know how to do this or where to look?
