Very Pleased with Service

Keo did the annual check up on my furnace. He was very polite and did a thorough job. I would recommend both Keo and Black Diamond to others

Great Service

Once again - impressed with the service received. Great effort to coordinate service with other serviceman Josh Taylor to address the problem and complete the work on a Sunday. Took the time to explain the problem and explain the work to be done. Very professional.
