Jerry...thanks for your thoughts. I actually have a cheesy, insulated, west facing garage door. I won't say that the insulation doesn't help, but ...I wish it helped more! I need to find someone to blow more insulation in the ceiling of the garage and I definitely think it's a strong first step. The issue is finding a qualified person to do it.
The house was built in 2012, so it has radiant barrier etc. I added the attic hatch insulation cover where it unzips to allow you to enter the attic and tries to block the heat from coming out of the hatch. The hatch also appears to have insulation board.
Part of my issue with a minisplit is having a location to put the outside unit where the HOA won't complain (I'm allowed 1 minisplit system OR a window unit, but it has to be covered up and in that location, it could become difficult to create a covering since it's in an unfenced area between my house and the house next door - I can't fence it off so I might have to add more bushes on the property line to cover it up)
Then...there's the $$$. I don't do this full time...I'm just a part time hobby person. My main crafting is weaving, knitting, sewing etc. I just build tables or custom tools for my crafting! I would eventually like to convert my garage into a "makerspace", which would have a CNC, 3D printer and such. But at the rate I'm going, I may only be able to tolerate that garage 50% of the year.
One step at a time...I'll keep working on getting the insulation in first, since I can't do anything without that.
