"Every winter I call BBHC and have Brett come to look at my HUGE furnace in my TINY house.. everything always checks out ok.. one winter I had an issue and called him on a saturday night, not only were him and Rhonda available, they had no problem offering me help :)"
"As an Industrial Sales Engineer for 40 years, calling on American Industry, it was my job to sell the customer on how to improve their installation, not just replace it, and I compliment you for your suggestions on how best to improve what I have. As I discussed, I was only interested in dealing with units that were manufactured in the United States, and supporting our industries and economy, thanks again."
"Thanks for your revised Proposal and the drawings. I would like to compliment you in the way you quoted the job and showed me first the newest Burnham Boiler, and the improved method of dealing with the (3) Zone Valves and the reasons for this method."
"During the past week, I have had several other Heating companies in to view my installation and you are the only one that has offered how it could be improved, other than going to a High Efficiency unit, which I am not interested in doing."
