Living Florida... Well I believe that is all that needs to be said. It was 103 degree in the shop (Garage) over the past week, with the humidity is was bad. Not a good place to work.
I installed 2 A/C - Heating ducts... plumbed off one of the sub manifolds.
The shop is now 3 degree warmer than the inside of the house. I believe some insulation in the ceiling of the garage will solve that issue.
