Commercial HVAC Solutions Built for Central Florida Businesses

Operating a commercial property in Central Florida means confronting relentless heat, punishing humidity, and the constant demand for reliable climate control. Since 1992, Mills Air has grown to be one of Central Florida’s largest and most respected companies, providing a complete line of products and services in air conditioning, heating, and indoor air quality. Our commercial HVAC division serves businesses of every size, from standalone retail locations and office buildings to large-scale industrial facilities and hospitality properties. With a staff of over 75 people and a fleet of trucks ready to respond, we bring the infrastructure and expertise necessary to keep your commercial operations running without interruption.

Commercial HVAC systems differ dramatically from residential units in scale, complexity, and regulatory requirements. These systems often incorporate rooftop units, variable air volume systems, chiller plants, cooling towers, and sophisticated building automation controls. The U.S. Department of Energy estimates that heating and cooling account for nearly 40 percent of a commercial building’s total energy consumption, making the selection, installation, and maintenance of these systems one of the most consequential decisions any property owner or facility manager will face. We understand these stakes, and our team is equipped to guide you through every phase of a commercial HVAC project.

Comprehensive Commercial HVAC Installation Services

When it comes to new construction or major retrofits, commercial HVAC installation demands meticulous planning and precise execution. Our process begins with a thorough load calculation that accounts for building orientation, occupancy patterns, insulation values, window glazing, and internal heat loads from lighting, equipment, and human activity. This engineering-first approach ensures that every system we install is appropriately sized, avoiding the efficiency losses and premature wear that come with oversized or undersized equipment. Leon Mills is the Founder and CEO of Mills Air, and Leon’s goal from day one has been to provide the best quality service and equipment to our valued customers while building an internal culture of team and family. That philosophy drives how we approach every commercial project.

We work with leading commercial equipment manufacturers to specify systems that match each building’s unique requirements. Whether the application calls for packaged rooftop units for a strip mall, split systems for a multi-story office complex, or variable refrigerant flow technology for a boutique hotel, our installation teams have the training and certifications to deliver turnkey solutions. We also coordinate closely with general contractors, architects, and engineers during new construction to ensure seamless integration with other building systems, including electrical, plumbing, and fire suppression infrastructure.

Preventative Maintenance and Ongoing Service

The lifespan and efficiency of any commercial HVAC system depend heavily on consistent preventative maintenance. Industry data from ASHRAE indicates that properly maintained commercial equipment can operate 15 to 20 years or longer, while neglected systems often require replacement in under a decade. Our preventative maintenance programs are designed to protect your investment and minimize costly downtime. In addition to routine preventative maintenance checks, service of existing air conditioning equipment, and installation of new air conditioning equipment, we also offer energy surveys that can uncover ways for you to reduce costly utility bills.

A typical commercial preventative maintenance visit from our technicians includes a detailed inspection covering critical system components. Our maintenance protocols address the following areas:

• Refrigerant charge verification to ensure optimal cooling capacity and compressor protection
• Electrical connection inspection including contactors, capacitors, and wiring integrity
• Condenser and evaporator coil cleaning to maintain heat transfer efficiency
• Belt and bearing inspection on air handling units and fan assemblies
• Thermostat and control calibration to ensure accurate temperature regulation
• Drain line clearing to prevent water damage and indoor air quality issues
