I'm having a free standing 28'x 36' motorcycle room/shop built by the house. Perfectly even heat is not critical but I do want it well insulated and efficient to heat/cool. The interior will consist of three rooms; 24'x 28' with two rooms 12'x12' and 12'x 16' off to the side. No doors just 3' openings.
The builder has proposed a Carrier mini-split Performance 40MAQB18B-3 single zone Highwall, and 38MAQB18R-3 single zone outdoor.
I know nothing about mini-splits other than the names Mitsubishi and Toshiba. Carrier seems well thought of in conventional HVAC and is what the HVAC contractor, that my builder uses, sells.

Does a mini-split make sense for my application? Any thoughts good or bad regarding Carrier mini split?

If I understand it right you want to provide heat and air in all three rooms which will be open with no doors on the rooms themselves. A mini-split could do the job with three high wall heads IMHO. I have used mini-splits in aircraft hangars for the offices with good success but not for the whoe hangar space.

I currently have a 3,575 sf shop and I use a Ruud heat pump and it stays comfortable year around. Due to the size of my shop a mini-split is not doable for me. I suggest you consult a Q manual to get a good idea of the size of units you need to handle the cubic feet of air in the building you are planning. Good luck, a shop is wonderful thing to have.

Damn I thought I'd posted this question but when I searched somehow overlooked it and assumed my feeble old mind just forgot to so asked again.
Sorry I'll try to delete this.

And thanks for the reply tatortodd.

Has anyone used this site or the Pioneer brand?

Another question for the gurus: Any suggestions for finding a contractor or HVAC person to install customer provided equipment? Most of the places around here seem to only want to sell and install, and their prices are insane for the hardware.
