I am in the process of having my 13 yr old heating and air-conditioning changed over to heat pumps (since I now generate more power than I consume from my new solar array). Verde SolAir is doing the work. Since i am now mostly retired I can "supervise" their work. Everything has not always gone perfectly with every effort, but they keep working on the problems until they are resolved. They appear to have a good team, and they seem to care about their work product and my satisfaction.
