I thought Rucker Mechanical was very good, and I would absolutely recommend them. During their last visit, one of their service people came and put a filter in my system. He was dressed appropriately and did a good job. He was speedy and efficient, and showed me the work he did. My most recent experience though was speaking with one of their office staff, who had called me back to make sure we had received their quotes on new units. They were very good, and I will definitely consider them. I don't have anything negative to say, they are a good company.
