Today, we continue to serve homes and businesses with repairs, installations, and maintenance across many system types. Customers choose our team because we believe in clear communication, fair pricing, and doing what is right on every job we perform.
Built on Family, Hard Work, and Purpose
Mark Duncan reached a turning point in his HVAC career when the opportunity came to start his own company. In May 2008, during a severe financial crisis, Mark and his wife Rachel opened Duncan’s Air Conditioning & Heating while raising four young children. That beginning shaped the company in lasting ways because success depended on hard work, resilience, and trust from the start. We know the value of responsibility because it was part of our story from day one. As a family-owned and operated company, we still treat customers and team members like family, and we work hard to earn confidence through honest service every single day.
Hands-On Leadership and Honest Recommendations
Mark Duncan has worked in the HVAC industry since 1997 and remains active in the field alongside the team. That hands-on leadership helps keep service standards high and decisions grounded in real customer needs. Duncan’s Air Conditioning & Heating is known for honest recommendations, clear explanations, and solutions that fit both the property and the budget. We are not focused on one-time sales or pressure-driven replacement tactics. Instead, we work to build long-term relationships through dependable workmanship and straightforward communication. Customers know they can expect practical guidance whether they need a repair, routine maintenance, indoor air quality support, or full replacement planning for older equipment.
Training, Quality, and Community Trust
Our team includes highly trained professionals who handle service, installation, and maintenance for residential and commercial HVAC systems. We employ NATE-certified technicians, service multiple brands, and continue training so we can address issues on many system types with confidence. As a Trane dealer that also works with brands including Daikin, we focus on giving customers options and useful information. Duncan’s Air Conditioning & Heating is also proud of its BBB membership since 2008 and the reputation we have earned through dependable local service. Those values, combined with strong technical skill and respect for every customer, continue to shape the way we work each day.
Duncan’s Air Conditioning & Heating stands apart by combining personal care with professional structure. We deliver the responsiveness and accountability of a local family business while offering the consistency, training, and dependable service customers expect from an established HVAC company serving both homes and businesses across Orlando.
Our goal is not simply to finish a job and move on. We want to earn trust, provide comfort solutions that truly help, and build lasting relationships that turn first-time customers into lifelong clients who know they can count on our team year after year.
