Dustin was here to perform a check/tuneup on our central air conditioner. As with every Black Diamond employee we have encountered , Dustin was very professional, friendly and explained exactly what he was doing. We have used Black Diamond for several years now, including purchase of central air, furnace and plumbing repairs. We would not consider changing companies.
