Client Testimonials

"It is not often you find people you can trust implicitly, let alone contractors. But Gary beats the odds. He's honest, fair and clever in his approach to his clients and his work. He built an elegant solar DHW system for me that works beautifully. I have recommended him to a friend for which he has done work. I would not hesitate to do that again."
- Jim S.
"Gary installed radiant heating in our 3400 sq ft home. His price was fair, his workmanship perfect, timely and the efficacy of the radiant heat is amazing. I would highly recommend Gary and Sunfire to anyone interested in installing radiant heating. One has only to have a radiant heated home experience to fully appreciate how effective it is. Thanks Gary."
