Travis and his team did a great job installing new ductwork in our crawl space to the existing vents. They made sure all debris was removed and the system was clean. They were on time, efficient, respectful and thorough! The cleanup was great. Will definitely use Keeven again. Services: HVAC duct & vent repair, HVAC duct & vent installation

Utilized Keeven to replace heat pumps with geothermal. When the vertical well fields didn't go as hoped they quickly adapted to horizontal line boring and were able to get that quickly installed. They were able to resize duct and get both systems and water heaters replaced and phased over so we were not without heat or water for any real duration of time. I would definitely recommend them especially for geothermal since it is mostly what they do. Overall it's an expensive proposition but from what I am seeing I would definitely recommend it.

Rude over the phone and will not sell parts to customers because they want to charge you to install them.
