Black Diamond Plumbing & Mechanical, Inc. is a family-operated company founded by Rick Sperando and Scott Underwood in 1999. We believe in hard work, a solid determination to excel, and a wholehearted commitment to the well-being of our customers. Unlike most HVAC contractors in suburban Chicago, we’re more than just an air conditioning company. Our residential and commercial clients appreciate that they can get circuit breaker panel upgrades from our Electrical Division, a furnace replacement from our HVAC Division, and a gas line repair from our Plumbing Division. We’re thriving, and our future looks bright.
