Quality First is not just the name of this company, it is the very essence of who they are. Sean Harkin worked on our furnace. He was courteous, friendly and very efficient. He took time to show and tell us what he was doing and why. It was without question a Quality First experience. I would not hesitate one minute to recommend Quality First for any plumbing and heating issues. Every one from the staff in the office to the field team were professional.
