As I’ve written in several posts , electrification is all the rage. Modern air-source heat pumps (ASHPs) are fantastic technologies, and they can provide reliable, efficient, clean, affordable, and sustainable heating and cooling when done well and in the right application. I worry that these caveats are too often glossed over. I’ve also seen really bad heat pump installations, and I think it’s easier to screw up a heat pump than a boiler or furnace.
This post is an overview of the process I suggest for good ASHP installations. I’ll be doing a post for each of the steps here, but this first post is an outline of the whole process because I believe the whole process is really important. The focus here is on homes, mainly in colder climates, and I’m not talking about VRF systems. I use the generic second person, so “you” can refer to different people in different steps.
