Company History and Growth
The story of D & D Heating & Air starts with hands-on work. Owner D began in the HVAC industry almost 20 years ago, cleaning ducts and furnace cabinets. He quickly moved into service and installation, gaining deep experience in both residential and commercial settings.
This foundation of practical knowledge shaped the company's growth. Instead of just expanding, the focus remained on mastering the craft. Today, that means having the right certifications—like Master Mechanical, EPA, and NATE—to back up every job.
Leadership and Local Roots
Owner D runs the business with his wife, Darlene. Married for 18 years, they have four children and are active members of their community. The family attends Thrive Church in nearby Westminster, and faith is a cornerstone of their lives and how they operate their company.
When not working, you might find them enjoying Colorado's outdoors or traveling to Lake McConaughy in Nebraska. This local, family-oriented presence means D & D Heating & Air isn't just a service provider; they're your neighbors who care about doing right by the community.
