I first would like to thank everyone who responded to my last post regarding some options on heating / cooling my new attic addition.
I have had 3 contractors out bidding for the job, and as expected got 3 different options, as best, most efficient way of heating/cooling the attic.
Option #1 (not tax rebate)
Install a dual-mini-split Fujitsu ductless system. 2 zones (Attic is split into 2 rooms) this would require running tubes down the side of our house to the outdoor condenser (not really happy about that).
Option # 2 (No tax rebate)
Install a dual-mini-split Dakin (sp?) unit with 2 zones as well. This unit supposedly can work with it being 5 degrees out. (We live in New England). This contractor told us he can run the wiring along the side of the house to blend with our borders.
Option # 3 (possible tax rebate)
Install a premium Carrier 15 SEER 2 ton Heat Pump with 2 ton variable speed handler (FE4ANF002) and the electrical heat package from Carrier. The ductwork was included in the price. However, the electrical needed for the units was not priced in the quote, so not sure what that would go for.
Option 1 & 2 were the same price, while Option 3 was higher.
I was hoping to get some feedback on peoples experience, knowledge regarding these options, as well as the most durable option. I am new when it comes to all of this. The attic will be used as a “game room” and Office. I would rather not use window AC with electric baseboard heat, which is the cheapest alternative (from what I’m told).
