Had our home built over 6 years ago. Dorrian installed our heat pump. Had problems with the heating and cooling from day 1. We called in regards to issues and the owner was very rude and refused to come out. We called the builder of our home and they finally stopped by. Obviously nothing done as we continued to have problems even after calling in 2 more companies. Today we had Ryan Garvey of Wolin come out and after a few hours of troubleshooting our unit it blowing wonderful cool air. So grateful it is finally fixed !
