Current Central Air unit at end of life.
I had a home inspection on a property that I will be renting out at first but moving into as a primary residence (sooner than later, I hope).
The central air conditioner unit is near the end of its life.
The house is masonry with two party walls and a relatively compact footprint of 1800 sq. in 3 floors + basement. The top floor is a woodbeam and plank peaked ceiling with some compact insulation between it and the real roof. The house was built in 1963. I believe it is single zone.
Do you recommend a particular manufacturer for this type of application? Is it worthwhile going super high efficiency? Would it be worthwhile breaking a relatively compact house like this into zones? (I have noticed that some people have an extra window unit or split unit on the very top floors of houses in the neighborhood, which range in age from 1840ish to 1980ish.
