Looking at 2600RB. Has one 15K air. They show heavy insulation in this unit. Wondering how well they cool when it's really hot? Unit is about 29' box maybe 25'. Thanks in advance.
If you are going to be in the south, I highly recommend having 2 AC units.
We spent this summer in Savannah and started with one AC unit. By memorial day we had the second unit installed. Thankfully, we had the 50amp service and 2nd AC prep from the factory.
It all depends on where you'll be, but I can tell you for sure you'll want 2 if you'll be anywhere in the heat!
