A/C

If your garage is attached to your house like mine was, there is a firewall in the attic between the garage and house that I could not go through per code. Therefore I could not add to the homes A/C ducting to extend into the garage. Adding ducting also reduces the air pressure of the homes HVAC system as there is more distance and more openings when you add to the system and just isn’t worth the money. Our solution was a 2 Ton Mini Split Heat Pump to go into the garage. It did cost about $2,000 but was well worth it. As the middle of summer in Sacramento, California would reach temperatures of 110’F+ it would still be 65’F with all 20 gamers, gaming away in the garage wrapped like burritos in blankets!

Insulation

Garage Door’s are huge in letting Thermals from the outside in. Consider a double insulated garage door and new seals around the door.

After everything is done, set, installed, wires ran in the walls, ect., consider spraying fluff insulation in the attic area above the garage.

Adding insulation in the walls of the garage is always a plus, mine garage was already finished with walls and I’m pretty sure they were not insulated, but it turned out not to be an issue.
