My family has been doing business with Bintz for over 30 years. Every time they have come to service our equipment or install a new furnace or air conditioner, it has been in a timely matter. They are efficient and upfront, only doing the things which need to be done and explaining to me why they are doing it. They also were very careful to ensure my carpeted steps stayed clean by putting tarps down. I would recommend this company to all my friends.
