Custom Ductwork & Sheet Metal Fabrication

Our in-house sheet metal fabrication shop allows us to design and build custom ductwork and ventilation systems for any size commercial project. Whether you’re upgrading an existing system or constructing a new facility, we deliver precise, efficient airflow solutions tailored to your building.

Light Commercial HVAC

We provide expert HVAC services for restaurants, offices, retail stores, and small commercial buildings. Our EPA-certified technicians handle installations, repairs, planned maintenance, and system controls — helping your business stay comfortable and energy-efficient year-round.

Industrial HVAC

For large-scale projects, Reliant Radiance has the skill and experience to manage industrial HVAC systems for multi-family housing, schools, warehouses, and manufacturing plants. We ensure consistent comfort, indoor air quality, and energy performance across every zone of your property.

Rooftop Units

We install and service gas-fired and all-electric rooftop HVAC units, including make-up air systems and economizers for improved air circulation and efficiency. Our technicians are trained to maintain and optimize rooftop systems for maximum reliability.

Mini-Split Systems

Mini-split HVAC systems are ideal for buildings with unique temperature control needs. These energy-efficient units allow for zoned heating and cooling, perfect for offices, server rooms, and areas where ductwork isn’t practical.
