Rooftop Heat Pump: Commercial Solution for Large Buildings

28/02/2026

A rooftop heat pump provides heating, cooling and ventilation through a single packaged HVAC unit installed on the roof of a building. The RTH45 rooftop heat pump delivers powerful climate control for commercial and industrial spaces while optimizing energy efficiency and saving valuable indoor space.

Many businesses choose rooftop HVAC systems because they offer centralized air distribution, efficient operation and reliable performance for large buildings such as warehouses, retail stores and gyms.

What Is a Rooftop Heat Pump?

A rooftop heat pump combines all major HVAC components inside a single outdoor unit installed on the roof of a building. The system distributes conditioned air through ductwork installed inside the building.

Unlike traditional split air conditioning systems that separate indoor and outdoor equipment, a rooftop unit includes all essential components in one cabinet:

• compressors
• evaporator and condenser coils
• air handling fans
• control systems

This design simplifies installation and maintenance while freeing indoor space.

Heat pump technology allows the system to reverse its refrigeration cycle. During warm months, the system removes heat from indoor air and cools the building. During colder periods, it extracts heat from outdoor air and transfers it indoors.

This dual function makes the rooftop heat pump an efficient and practical HVAC solution for commercial facilities.
