We had a Mitsubishi mini-split heat pump system installed in 2019, to replace a pair of gas furnaces. We love the system, but finding an installer was more difficult than I had expected. Almost every HVAC installer wanted to install new gas furnaces and be done with it, even those which mentioned heat pumps on their site. They might have eventually been cajoled into installing what we wanted, but that wasn't the kind of vendor we wanted.
We ultimately found Alternative HVAC Solutions, which specializes in heat pumps and leads with them as the solution they propose. They did a fine job and I do recommend them for anyone looking for an installer on the San Francisco peninsula.
However this morning I had to SQUEEEE with excitement at seeing another firm proudly leading with heat pumps as their preferred solution: Electric Air. I cannot speak from personal experience about their service, it is just nice to see how far we have come.
