Hi. I was investigating pellet stoves and wood stoves as an alternative to oil heat when members of the Hearth Room brought mini-split heat pumps to my attention. I did a little homework and had 3 companies come out to give me estimates. Their solutions and prices are so different from one another that I don't know where to turn next. Below are details: my home: 1,300 sq ft, 2 story, built in 1950s Company #1 solution: 2 downstairs units + 2 upstairs (1 per bedroom); total of 36,000 Btus; cost = $12,350 after $250 utility company rebate; ineligible for tax credit Company # 2 solution: 1 downstairs + 2 upstairs (1 per bedroom); total of 42,000 Btus; cost = $9,300; ineligible for utility company rebate or tax credit Company #3 solution: 1 downstairs + 1 upstairs (in hallway pointing at bedrooms); total of 24,000 Btus; cost = $6,300 after $250 utility rebate and $300 tax credit Each company uses Mitsubishi units, and each is charging me ~$3,100/unit after rebates/tax credits. How many units and how many Btus do I really need? Are the prices reasonable? If you have advice, I'd love to hear from you.
