About Us
Chicagoland, IL HVAC Contractors

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.

One Simple Philosophy

At Black Diamond, it’s all about our clients. We need our customers as much as our customers need us. We believe in going way beyond the call of duty. Whatever it takes to ensure your complete satisfaction — that’s what we’ll do. Whether you need an air conditioning company, a plumber, or electrical contractors for construction, blue-ribbon service is what you’ll get.

Three Key Principles

We believe that our success is based on three simple things:

• We always answer the phone – Day or night, 365 days a year, your call will always be answered by a Black Diamond employee
• We do what we say we are going to do – Our professional, prompt technicians will arrive when we promise.  With our free estimates on installs or replacements and flat-rate pricing, you always know the price before we do the work.  No hidden charges, no extra fees.
• We surround ourselves with the best people – We hire professional employees that are willing to help our customers no matter what. With their “whatever it takes” attitude you can rest assured that we’ve got you covered.

A Winning Team

Our staff includes over 50 professionals and NATE-certified technicians. We hire talented people who specialize in award-winning customer service. At our state-of-the-art training facility, our technicians polish and hone their skills, learn new techniques, keep current on building codes, and stay informed about all the latest technologies.

Community Investment

• Multiple Chambers of Commerce
• Various Local Park Districts
• Downtown Crystal Lake
• Operation Click
• Lake County Fair
