A multi-story medical office building in downtown Los Angeles needed a modern, flexible HVAC solution to replace an aging chiller system. LA Air Dept designed and installed a Mitsubishi City Multi VRF system to deliver precise zone-level comfort control across all floors.
LA Air Dept engineered and installed a full heat recovery VRF system serving 24 zones across four floors, allowing simultaneous heating and cooling in different areas while dramatically improving overall energy efficiency.
The phased installation was carefully coordinated around the building's operating schedule, with each floor brought online progressively to minimize disruption to patients and staff.

"Our building's energy costs dropped significantly and the comfort complaints from staff and patients have essentially disappeared. LA Air Dept delivered exactly what they promised."
The project began with a detailed building load analysis and zone mapping. Equipment was specified to meet both comfort and redundancy requirements for a medical facility. Installation was phased floor by floor to keep the building operational throughout the project.
