What Heat Pumps Actually Need to Work

Chris and Phil sit down with Scott Libby of Royal River Heat Pumps, a 41-year HVAC veteran who spent his first 25 years telling people heat pumps did not belong in Maine. He changed his mind, built a company around them, and now has 40 employees doing nothing else. They get into what actually makes a home a good candidate for heat pumps, why multi zone systems keep causing problems in high-performance houses, what bad installs look like in the field, and why the new refrigerants are about to make mechanical room sizing a lot more complicated. It is a candid, field-level conversation for architects, builders, and building science nerds who want the installer's perspective.
