My home was constructed sometime in the mid 1730’s and is nearly 3000 square feet.
It has ten foot ceilings, huge windows and the original hardwood floors. When the two of us moved in, the home was just about impossible to heat and cool, then not only was the gas furnace and air conditioner seriously aged, however the HVAC duct was full of holes and leaks at the seams. The windows were single pane, painted shut and allowed drafts inside. None of the exterior doors shut tight, allowing outside air to come in and heated/cooled air to escape. There was no insulation in the walls, ceilings or attic. It has taken us nearly ten years to make all of the necessary improvements to the thermal envelope. There are 25 windows in the home and they all needed to be replaced, most of them are unusual sizes and required special order. The expense added up really suddenly. The walls and ceilings in the home were the original plaster and lathe. Many of them were cracked and crumbling, then one by a single, the two of us gutted every single room in the house, splitting down to the studs. This allowed us to replace electric lines, plumbing pipes and HVAC duct. It provided us the opportunity to carefully and thoroughly insulated. The people I was with and I took out a modern home improvement loan to update the old gas furnace and air conditioner and spent extra to get a high efficiency, variable speed system. The modern heating and cooling plan allowed us to take advantage of zone control. The people I was with and I now have independent control units in each room, providing the ability to customize temperature. We’re no longer required to maintain perfect comfort in unoccupied areas.
