I hired Shane to conduct a combustion analysis on my furnace, to determine the carbon monoxide ppm level. He came on a Sunday after I was told by a different company I needed a furnace replacement due to a “failed” analysis. Shane was honest, knowledgeable and professional. He conducted a thorough analysis and found that our furnace was safe and not producing harmful levels of CO. I am grateful for Shane’s service and pragmatism, and I will hire him again.

I have recently had a furnace repair and a hot water tank replacement Shane and his employees are in and out very quickly and very efficiently everything was done to code and after they were done you couldn't even tell they were there .Definitely would recommend them if you want to get the job done right.
