Heat pump for garage -- mini split vs portable?

I want a heat pump for my garage. It's a 3 car garage. I don't need it to be 70f in the middle of winter but would nice not to need gloves. I'm trying to decide between a mini split and a portable unit. A cheap mini split is a couple hundred more than the portable.

Installation is much much easier with the portable. 2x 4" holes in the garage is all I need. With the mini split, it's a little harder. Another benefit of the mini split is having it up on the wall instead of another thing piled up in the garage.

Any advise? What else should I consider?

 

I plan on doing a mini split in my garage, now wood shop. They are efficient to run, and don’t take up floor space.

 

don't dismiss a through the wall heat pump.

 

Are you talking about the ones that are usually.in hotel rooms?

 

more or less, there are ones that can go higher on the wall like a mini-split's cassette
less complicated than a split (no line st to run) and it's up off the floor

 

How cold does it get where you live? Heat pumps don't do too well in the lower 30 degree range.

 

My heat pump has been heating my home in sub freezing temps here in Texas during this polar event December 2022 with no problems. It’s a dual fuel system (propane backup).
I have 3 mini splits on my shop and one for the tack room and one for the office. Make sure you get a good one I went with Mitsubishi better support from the manufacturer. The Chinese ones are throw always when they fail no parts available. It’s just their way of doing business. I’ve been in the industry for 50 years. The early heat pumps from the 80s to the early 90s were a learning curve for the manufacture’s. The first heat pump came out in 1856.
