Since we moved into our new house, we haven't needed the central air until a couple of weeks ago (and especially last week, when temps got way too close to 90 degrees). But although the furnace works and the A/C was rewired, it turned out the whole thing needed replacing. Yesterday, our daughter-in-law's go-to contractor, Ron got it working. What a relief! Of course, we're now looking at a couple of weeks in the low 70s.
