"HIred company for a whole house humidifier installation/replacement. Don was very professional and thorough; he made sure we had the right system for our house. Additionally, he not only took the time to make sure that we knew how to work the system when he left, but also explained the reasons that he installed it differently than the original installation. The price for the installation was also more competitive than the other service providers that we were matched with for the job."
