If the Culligan man was in your house and recommended plumbing and heating repairs, would you take the advice?

We are in the process of partnering with Culligan Water Products. We have been in business for 23 years as a plumbing and heating contractor. As the franchise works out we would have to use seperate trucks but the same employees. My question is if a Culligan man was in your home and he knew what he was talking about in reference to heating service work that needed to be peformed on your home heating system would you take his advice? Or would you blow it off because after all he is wearing a Culligan shirt? We are a licensed, bonded, and insured plumbing and heating contractor. We have 7, 2 card carrying journeymen plumbing and heating technicians.
