Here in Florida, summer is brutal with heat and humidity. There really isn't winter season here.
We get cold spells a few times but never below freezing.
Our house is facing North, East side is shaded but West side faces afternoon sun.
We took out windows on west side of house so it will help with cooling downstairs. The raised floor is insulated.
There is one room downstair not covered by upstairs but the rest are.
I don't know how I can tell if the air handler for upstair was for the 5 ton or was it downstair handler. The old units were stolen.
You want me to 'stop-by'.
