I have a 2 story house in southern California. It has dual pane windows replaced within last 7 years. The house is 3200sqft equally split up and down.
It's orientation is front facing east. The walls and ceiling and floor insulation would be whatever the title 24 called for in the late 60's. probably nothing that great (R11). Now there is a 5 ton unit in place right now, it's just old.
What would you experts recommend?
1) size of units?
2) 1 or 2 units?
3) what kind of equpment?
4) would you recommend any attic fans?
I can't think of anything else. I'm sure I missed something.
Thanks in advance.
