Investing in a nice ductless mini split for my shed

I am updating my backyard shed to be a work out environment for me.

I actually ripped down the drywall to insulate and replace with new.

I got brand new windows installed and a better overhead light fixture. The last step is that I need some style of Heating and Air Conditioning device. A lot of people are telling me to just get a window A/C device. You can get just a window air conditioner device or a better component that does both heating and cooling. I don’t really know if I like the whole idea of hiding my brand new windows with a bulky cooling unit. There are other Heating and Air Conditioning machines that sit on the ground and vent outside. They look absolutely exhausting and will take up floor space that I need to workout. I have been leaning towards calling a professional Heating and Air Conditioning contractor and getting a ductless mini split installed in the shed. It will cost quite a bit of currency though. The HVAC component will be mounted high on my wall and out of the way. It won’t take up any additional space and look unquestionably modern. Also, my one ductless mini split could handle the shed with no problem. I could have quality heating in the frosty season or heavy duty A/C in the hot season. There would be no day that I could not workout… However, I would spend a couple grand to have good climate control in a shed that I use one hour everyday. Is it absolutely worth spending that kind of currency for heating and cooling? I wonder how long the ductless mini split will last. If I keep it long enough then it would certainly be worth the investment.
