@derek I just bought a house in late 2022 had one winter of the oil boiler and a summer of a stifling upstairs and was just DONE. There was a local plumber who was installing heat pumps in a lot of the neighborhood houses (my town has 4500 people) and I had him write me up an estimate. It was a *serious* capital outlay, but having unstuffy bedrooms and "bespoke" heating and cooling (i.e. per room, otherwise it's just upstairs/downstairs zones with the boiler) has been a game changer.
