I am jsut overwhelmed with how wonderful the people are Stiles are! A freind recommended them when the folks who sold me my fuel pump evidenced little interest in mainting or servicing it. They are prompt and courteous, and go out of thier way to be helpful. On the first visit they removed all the old filters sitting around my basement telling me that their policy was to clean up not only after themselves but after everyone else so that the customer would assoicate neatness with them. He also dug a hole, filled it with a plastic flower pot holding gravel so the water would drain into my flower bed rather than my lawn. I signed up for a tri-star service agreement, and a week later when my circuit boadr blew out, they came over immediately and replaced it at NOCOST!
