What Sized AC for Phoenix AZ for an uninsulated two car garage?

[chrisski]

For an uninsulated two car garage on the North side of the house, what sized AC Woukd you install?

This would be to maintain 80 in an area normally 105f to 110f in summertime.

Insulating not an option.

I bet I’m not the first forum member to try this on Phoenix AZ or Las Vegas.

Need more info (how many outside walls, size of walls, ceiling height, anything above the ceiling), but just a wild guess: one ton could do a normal 400 sq ft room. Uninsulated room, I would guess two tons to get 105 outside down to 80 inside.

Insulating not an option.

Why not?

And what is the purpose of cooling the garage? Batteries and inverters? Could you build a small insulated room for them?

Google how to do a proper heat load calculation. There are plenty of descent online calculators.
