Ken went right to the problem and knew how to test his assumption. Seems that the diagnostic fee could be credited against the repair of $600.
Response from Bradbury Brothers Cooling, Heating, Plumbing & Electrical:
Thank you for your feedback! We are aware that many of our competitors offer to credit back their service fee if services are performed. There are costs associated with sending a licensed technician/plumber in a fully stocked vehicle to a customer’s home. Typically, any company that credits back the service fee when a repair is performed has hidden that service fee right back into their pricing. The issue we have with this practice is that any customer that chooses to do multiple repairs at the same visit is now paying for that hidden service fee multiple times. We prefer to keep this service fee separate so that we are more upfront and honest in our pricing. We do appreciate you giving us such a nice review and letting us know that we were able to get you taken care of. Thank you for giving us the opportunity to serve you.
