My wife and I raised three kids in a big house in the suburbs. We had our share of problems, like all households, but the overarching memories of those days are absolutely of adoration and fun. The kids always like to “help” rake the leaves during the fall by diving into the piles, spreading the leaves all across our lawn, only to rake them back up again. The house had a good amount of space for parties, sleepovers, and each of our kids had their own room. It was a wonderful time, and we had a fantastic marriage. When the kids moved out, we just didn’t need all the space. Just the heating and cooling cost for that big house was a waste of money, so we followed the energy saving tips we obtained online and we decided to sell our big house and purchase a smaller one closer to the town center. A lot of the smaller houses in those neighborhoods had happened to be razed and replaced by McMansions, and those that still existed usually had gas or oil furnaces, but no central air conditioning. We decided that we would buy one of the older houses and backfit it using a central HVAC system for a nice level of comfort and efficiency. After consulting with an HVAC contractor, however, we found that those houses wouldn’t have air vents installed because the ductwork that the furnaces use would run to registers in their baseboards. If we wanted to set up central A/C or a heat pump, we would have to run new ductwork inside the ceiling and cut a whole lot of holes throughout the house. Subsequently, he told us about a ductless mini split heat pump that would work in most of these houses.
