I called for service for furnace (wouldn't heat) on Tuesday pm. I couldn't be home on Wednesday, and made appt for Thursday as I would be here all day. Promptly at 8:00 am, Handy Bros pulls in driveway. Problem diagnosed promptly, and repaired. Sheldon (the tech) was very knowledgeable and courteous. He explained everything as he was diagnosing and repairing the furnace. I would highly recommend Handy Bros. for all my furnace and a/c needs.
