@thomasfuchs@hachyderm.io Two reasons I've seen my heat pump recommendations fail: Urban area noise code: In Seattle it is often possible to get AC installed with a special use agreement, but heat pumps are held to a different noise standard due to night time operation. https://www.seattle.gov/documents/Departments/SDCI/Codes/ACUseAgreement.pdf Locked Rotor Amp calculations: PSE and other major utilities base their construction charges and transformer sizing based on LRA - often far more impactful than sq ft alone. transformation charges can exceed 10-20k plus traffic control and permits.
