Replacing AC/Heater?

[Connie Brzowski]

Quick question--

We rehabbed a place about a year ago with a window air conditioner. We're in TX and air conditioning is a necessity with heat needed only a few weeks out of the year. The attic space is extremely tiny (only 3 ft. at the peak) so we decided to go with another through the wall unit with a heat strip.

The model we bought is a Frigidaire and has been nothing but trouble. I'm ready to toss it to the street and find something else. Surely with all the new technology these days there's *something* new, wonderful and energy efficient to heat and cool a small home :roll:

Our wonderful tenant called today and the heat isn't working... *again*...

The place is 700 sq ft-- any recommendations?
