"If you need your gas furnace fixed, I recommend these guys with absolutely no hesitation, and in fact with highest marks. Right on cue, our furnace failed with the advent of the cold snap. The place where we bought it (many years ago!) told us it would be another week until they could come out (Really?!?). Luckily, a call to BNGS got us a same-day appointment. The repair technician showed up on time, was exceedingly polite and accommodating, great communication skills... he quickly diagnosed the problem after explaining and checking a couple of different possibilities, then went ahead with the repair as authorized. He was in and out of the house in a little over an hour. The price was right, I felt very good about the level of service and professionalism demonstrated by the technician. And we are very glad to have heat again!"
