Will be doing the same for my garage before summer next year.

His out the door cost of doing it himself was around $800 after he sold back, on the used market, his specialized HVAC equipment he bought to do the lines.

He got the most powerful 110 volt option and it's keeping his garage cool in the Arizona summer. He's got a living space above his garage so there's some extra benefits that he gets aside from just a comfortable garage to work in.

There are only a handful of manufacturers in the world, yet there's a ton of brands.

This is what he used. Bought it for like 650 on a deal from Amazon.
