Have had a service contract with Belair Engineering and Service Company since 2008. The Mrs. and I have always been very happy with the company and the service technicians that have performed maintenance over the years. The last two times service appointments were scheduled, Warren G. was the technician sent by Belair that provided the maintenance service. His professionalism, personality, and detail to the service tasks were outstanding. If available, we will specifically request that Warren G. service our heating unit when we set up our next appointment in the fall of 2016.
