Reliable Climate Solutions by Reliant Radiance

When it comes to efficient heating and cooling for large buildings, Rooftop HVAC units are one of the most effective and space-saving options available. At Reliant Radiance, we design, install, and service commercial rooftop systems across Denver, Colorado, providing dependable comfort and performance all year long.

What Are Rooftop HVAC Units?

Rooftop HVAC systems, also known as RTUs, are self-contained heating and cooling units installed on the roof of a building. They are designed to deliver powerful air distribution while saving valuable indoor space. RTUs are commonly used in offices, retail stores, schools, and warehouses.

These systems combine both heating and cooling components in one unit, allowing efficient control of indoor climate through a single setup.

Benefits of Rooftop HVAC Systems

  • Space Efficiency: Frees up ground and indoor areas for other uses.
  • Energy Savings: Modern rooftop units are built for high performance and reduced energy costs.
  • Easy Maintenance: All major components are accessible from the rooftop for quicker service.
  • Quiet Operation: Keeps mechanical noise outside your workspace.
  • Scalable Design: Easily expanded or upgraded as your building grows.

Frequently Asked Questions (FAQ)

  • How often does my boiler need to be serviced?

    We strongly recommend having your boiler professionally inspected and maintained once a year, preferably in the fall before the heating season begins. This ensures it operates safely and efficiently all winter long.

  • How long should a boiler last?

    A well-maintained boiler can last for 15 to 20 years or even longer. Regular service is the key to maximizing its lifespan.

  • What is the difference between a boiler and a furnace?

    A furnace heats air and distributes it through ductwork (forced air). A boiler heats water and moves it through pipes to radiators, baseboard heaters, or radiant flooring tubes (hydronic heat).
