The workers at Bay Heating Service are neat, clean, and courteous. I appreciate the fact that they work around the needs of their customers. Over the years, I’ve been very pleased with their service, and I get what I need done promptly. Last year we had a sewer backup in one of our buildings. They quickly checked out the situation and let me know what needed to be done. They’re very caring people, and I have confidence in them.
