I recently figured out that my backyard shed isn’t insulated. For a long time I would just freeze to death anytime I wanted to labor on projects. I figured I needed to add a furnace to the space in order to labor all year long. Thankfully I looked into the walls plus ceiling before purchasing my heater. I noticed the lack of insulation plus now my shed is getting a facelift. I replaced the windows for modern 1s that fit slim in the frames. I tore down the walls to add insulation in them plus the ceiling. Now that my space is totally airtight, it is not that freezing anymore. Am I totally comfortable? Not reallyâ€¦ Before my insulation project I was thinking of adding a ductless mini split. I figured I needed a powerful heating plan to keep me warm plus most likely would want AC in the summer. Now that the shed isn’t too bad on temperature control, I assume a easy space furnace will do the trick. I assume 1 small, electric furnace plus perhaps a window cooling system in the summer time will be good enough. If I go a year plus I am not totally cheerful with the level of heating plus air conditioner, after that I will call a Heating & A/C dealer plus get ductless replacement. I easily hope it does not come to that though. I just replaced my walls, sanded plus painted over them. The mini chop replacement would require a hole being drilled right in my strenuous work. It would be kind of ugly having a big component on the wall too.
