Help! My Garage Is a Sauna - Should I DIY a Mini Split AC?

Hey everyone! I've set up a small workshop in my garage, but it's super hot in there, especially during the summer months. I was thinking about getting a mini-split air conditioner since I found some decent deals online. I'm also considering installing it myself to save some cash, but I don't have a lot of experience with this stuff. What do you all think? Is it better to go for it and DIY, or should I hire a contractor instead? Any advice would be appreciated!

It really comes down to how comfortable you are with DIY projects. Some of the new mini-splits are designed to be user-friendly and easy to install. Just keep in mind, you might need to evacuate the lines and do some wiring, which can be tricky.

Honestly, if you can swing it, a window AC unit might be a better option. Mini splits can be pretty pricey and tricky to install. They're not exactly a walk in the park, especially if you're not experienced.

GarageGuru88: You could also consider a portable unit that vents out the window. It might be easier to set up!

As someone who's worked in HVAC for a decade, I'd recommend sticking with a window unit. Those Mr. Cool DIY mini-splits look cool, but you'll need professional tools that could be a pain to buy for just this project. If you really want a mini split, definitely get quotes from local HVAC contractors, but aim for a middle-tier quote for a better installation and warranty.
