Project Overview
A local business in the Southern California area needed reliable year-round climate control for its facility. BOMING Air Conditioning & Heating replaced the aging rooftop system with a new 4-Ton Commercial Heat Pump Roof Unit. 460Vs, 3 phase. The equipment matches the building’s existing three-phase electrical service and provides both heating and cooling from a single packaged unit mounted on the roof.
Why a 4-Ton Commercial Heat Pump Roof Unit 460V 3-Phase
Commercial buildings often operate on 460-volt three-phase power. This voltage reduces current draw and allows smaller wiring and breakers compared with single-phase equipment. A heat pump design moves heat rather than generating it, delivering efficient performance in mild Southern California winters while still providing strong cooling capacity during summer. Roof-mounted placement frees interior space and simplifies duct connections to the existing air-distribution system.
Installation Process
Technicians first verified the roof curb and structural supports. The old unit was disconnected, lifted off, and the new 4-Ton Commercial Heat Pump Roof Unit 460V 3-phase was set in place. Electrical connections were made to the 460-volt three-phase supply, and the control wiring was integrated with the building’s thermostat. After leak-testing the refrigerant circuit and confirming proper airflow, the system was started and performance readings were recorded to ensure it met manufacturer specifications.
Results and Benefits
The business now operates with a modern, factory-charged heat pump that offers consistent temperatures and lower maintenance demands than the previous equipment. Three-phase operation provides smoother motor performance and longer component life. Because the work was completed on the roof, daily operations inside the facility continued with minimal disruption. Property managers gain peace of mind knowing the system is backed by a licensed local contractor familiar with commercial HVAC requirements in the Chino Hills area.
