Trevor first arrived on a weekend emergency call and got our furnace working so that we had heat. He was upbeat and positive, even though he had to come out on a Saturday night. He then returned the following week with new parts to update our furnace to help prevent any future problems. He was polite, knowledgable, and did a great job. We highly recommend Trevor and East Coast Heating.
