I can't say enough good things about Grant and his Team. I had several bids for my new HVAC system knowing I had issues with airflow and every one of the other company's brushed it off as no big deal. Grant was the only one that came in and ACTUALLY did load calculations on our system and recognized the issues and came up with a proper solution. During the install there was more issues found with duct work and he fixed it while keeping me well informed on what had to be done. He takes a lot of pride in his work and wants to do it right the first time which isn't very common now adays. All I can say is thank you and if you have HVAC issues, he is the only one to go to!

Grant and his team were awesome to work with. They installed an entire duct system in a house we just purchased. The house previously had no ducts and just baseboard heat. Grant and team installed a duct system with a heat pump. They were professional and courteous and worked around our pets (2 dogs and 1 cat) very well. I greatly appreciate the work they did!

Grant and team did an excellent job installing a new heating system at our cabin. Grant was very responsive as well and kept us up to date on the entire process and was patient while answering our questions. I highly recommend using them for your heating/cooling needs.

We shopped around could not be happier with our decision to hire Grants to replace our AC and furnace during a heat wave. They are the experts! Grant presented multiple options and got us what we wanted at a price we could afford. The 4 technicians onsite were friendly and professional. Their vehicles, tools, and equipment were nice and well maintained. The workmanship on the install was top notch and they cleaned up afterwards like they were never there. They even stayed late to help us install the thermostat app on our iPhones and show us how to control system remotely and get alerts when there are issues, such as a leak. I own an insurance agency and will recommend Grants to all my clients. Thank you!
