Adding ductless HVAC to my shed

My outdoor shed had no heating and cooling.

At first I thought that was okay. I only worked out there an hour everyday. I figured I could just time my workouts to be when the temperatures are good. Well it didn’t work out that way. The wintertime temperatures are so cold. There were no warm times. I ended up buying a space heater. I would pre-heat my shed for hours and it still was freezing cold. I needed to wear long pants and a coat the whole time. In the summer the lack of AC was horrible. My box fan didn’t do the job at all. I was a sweaty, gross mess. I then made the decision to get HVAC in there. I looked at portable HVAC units but I didn’t want anything wimpy. I wanted to have the whole space at the right temperature for once. It was a lot of money, but I don’t regret getting a ductless mini split. I now have heating and cooling. I have a smart thermostat that I can control from my phone. It isn’t necessary though. The thermostat has learned what I like to do. An hour before I begin my workout,the HVAC turns on. I then have a perfectly cooled or heated space when I am ready to work out. What is nice is that my husband is talking about building a shed for his woodworking hobby. If he wanted HVAC, he could easily hook onto my unit. We would share the same outdoor air compressor. All he would need to buy is the indoor air handler and the thermostat.
