We had Olson Energy install 2 heat pumps in our home in he Spring of 2016, and we are so happy we did. They took great care of our house during installation, routed the piping in a very non-obtrusive way, and left the home as spotless as they found it. We noticed a problem within the first few days, and they came out and fixed it THE SAME DAY WE CALLED THEM, That was awesome. The units themselves do a beautiful job of keeping our home cool and comfortable. They are quiet and efficient. (Note – we chose heat pumps because we did not have existing venting to accommodate central AC integration with out gas furnace.)
