Some background - I'm just starting a two to three year process of renovation of an ~1800 two-story craftsman house in Central NY. This summer the focus is on some structural repairs to two of the three barns, and not so much the house. However, I am installing a 5.3 kW solar array in the fall and I thought I would get some pricing on mini-split heat pumps to provide winter heating as a near-term way to use the solar production and also to serve (ultimately) as the winter backup to the indoor wood boiler system I'll be installing in the future as part of the renovation. Ultimately, the heat loss at 0 degree F outdoor temperature will be (my estimate) ~20,000 BTUs/hour (I know how to calculate this with high accuracy). I was shocked to get a price of $10,000 for a two-ton system. I will be calling for some clarification from the company that prepared the quotation (their quotation doesn't list enough detail for me to understand all that they are providing). What it does list is as follows: Qty. 1 outdoor condensor - not clear if this is 24,000 BTU two-zone or larger with >2 zones - no part number is given. SEER rating is 21 Qty. 1 SLZ-KA12 Ceiling Cassette Unit Qty. 1 MSZ-GE12 High Wall Mounted Unit Installation, breaker panel additions, and remote controls for heating units. I am waiting to get a quotation from a second Mitsubishi installer. I am in a rural area, but I will also be trying to locate an LG or Fujitsu dealer as well to see if their prices are more reasonable. Is there any other advice can be offered regarding price, sizing, or efficiency in order to get this closer to a $5-6k install?
