We had an excellent experience with Sean and Fusion Star! When our old HVAC system gave up the ghost, Sean came highly recommended for his attention to detail and excellent service, and we were not at all disappointed. He helped us through the decision-making process with real expertise and we felt we were in great hands with the install, which went very smoothly and took less time than expected. The system works gre…

What started as what I thought was a simple blown fuse somewhere between our thermostat and our front HVAC system turned out to lead to a whole avalanche of problems.

We love Fusion Star! Sean came highly recommended years back and we had him install a dual zone mini split in our work space. It changed our lives and his attention to detail is second to none.

Highly recommended!

I’ve had two recent and exceptional experiences with this company. On both occasions Sean was quick to provide a detailed explanation of what was wrong and an action plan. He gave me a lot of his time diagnosing my existing system the first time around (he did not install it, and explained the issues I was having). The second time he came personally to help me out during an outage. His crew was there the next day and…
