Excellent Service

Gerad and his team did an excellent job! I would call them again on another project.

Meticulous

Prompt and professional service. Even though my furnace is only 2 years old, Keith really took his time, not taking anything for granted, and made sure everything was in perfect shape.

Service was great

However, I paid Black Diamond decent money last Friday, referred a client from my office on Monday and spent a lot of money with Black Diamond on Monday. It just seems like I spent an inordinate amount of money in two days. Jack O'Connor, Baird & Warner

courteous and thorough inspection

Nick seemed to check the critical readings of my A/C operation and advised me of where satisfactory performance was, where areas that were slightly under-performing and parts that showed excessive wear and were below a recommended range and the costs to have them replaced. It appears I'll likely be using my Crystal Club membership soon to save money on parts replacement in the near future.

Helps to have the right equioment

Very knowledgeable young man. Took one look at my leaky plumbing pipes and went straight to work. He did most of the smelly soldering work outside so my house did not smell of gas. Cut and crimped the connectors with a very cool tool and was soon on his way. Cleaned up after himself before he left. My neighbor had Black Diamond do some work on his house and if they could meet his standards, I knew they would be great. They exceeded my expectations.

Results, Risks, Recommendations explained

Heating operational check and cleaning. Put probes on key parts to determine operational efficiency and effectiveness and exposure to likely problems near term. I will consider replacing furnace over next 4-6 mos.
