looking at a replacement window air conditioner. Current one has lasted more than 10 years, wife
says it is starting to sound funny. it's a big 208/230 volt unit at least 18,000 BTU's maybe more.
it makes the dining room & living room comfortable during the summer(house built in the 20's, has steam heat
plaster walls, no duct work for central air). we get by with 3 air conditioners (finished basement stays kind of cool
till August). Sweet spot seems to be 25K BTU's under $600 for slide in chassis (install frame in window, slide in guts).
