I like these guys, and I especially like the owner, who gave us his personal contact information if we had any problems. We had some issues with the solar water heater at first, but that is now resolved, and it is working fine. Be sure they either paint the solar collector tubing insulation, or put on an insulation wrap that is UV resistant. The heat pumps work very well. We were called by Mr. Central about setting up the annual inspection of the system- we didn't have to call them.
