I have been calling Black Diamond for hvac and plumbing for a few years now and its bc the customer service is great and they get the job done. this time was no exception - from the receptionist who schedules the job to the technician :). they clean up after themselves and explain everything so that if its something I can prevent from happening they just as soon have me know how to do that and not have to waste any extra money - which I ALWAYS appreciate!
