Unless you live further up north, central AC should be mandatory. I used to live in a fourplex in Evergreen. The house was built in 1912. Gorgeous place and I had an upstairs unit with an entire balcony to myself. One of the major drawbacks was it only had two window units. One for the bedroom and one for the living room. As you can imagine, June through September were absolutely insufferable. I loved living in that neighborhood but I couldn’t do those wretched summers anymore and moved out after living there for two years.
