Quotes on minisplits
Revising my house heating/cooling upgrade. Four HVAC contractors went out.
1. Mitsu diamond dealer. Three units total- MXZ3C30NAHZ(two of these) and one MXZ2C20NAHZ, 2 5 port branch boxes, 11 HH highwall units total(different types) 1 floor console. Does not need upgrade of current electric box. Has a less expensive option that leaves basement at the mercy of the current EBB
2. Local HVAC- has done some minisplits, can get mitsu- six units total
4- MXZ8C48NAHZU1, one MUFZKJ12, one MUFZKJ12 and 15 inside units (many different ones listed) no branch boxes noted in this one. Required upgrading my electric to 400amps
3. Minisplits are impossible
4. Can do minisplits, will give me a quote based on cost of estimated hardware, but not sure where units will be placed or configuration will be.
SOOO- is this common? I know this house is more than a little challenging but heck, there’s a house worth of difference in the supply! Is there some other way that I should be going about getting these estimates?
Oh- here’s a link to the house. And FYI- this is an older pic and the arch part of the sunroom is now gone and the room is half the size with a deck.
