The owner Bob and his son have to be the most unprofessional people I have ever dealt with. Rude and sarcastic doesnt even begin to describe their behavior while in our home. I came very close to asking them to leave my home but sadly needed my furnace fixed so decided to bite my tongue. I am 60 years old and was yelled at and insulted by both father and son. I will not be using their services in the future.
