"Our service appointment was scheduled between 9 and noon. Our service tech, Rob Y, called around 10 to say he was on his way. Rob performed his service quickly and efficiently and answered all my questions. When we were in the basement he mentioned they also perform plumbing services which I did not previously know. Rob also gave us a "Peak Performance Promise" flyer which I recently have seen advertised on TV. Rob explained what he did and then emailed me a detail of the services performed. Very satisfied with Triangle and the quality of their staff." - Steve B.
