Scalable Configurations: From 6 HP to 48 HP outdoor units, supporting up to 48 indoor units per system—grow with your project .
20 Years Commercial HVAC Expertise: Engineering support, submittal packages, and after-sales service for project partners .
For large-scale commercial projects—hotels, office buildings, mixed-use developments, and institutional facilities—traditional HVAC solutions often fall short. Ducted systems waste energy in partially occupied spaces. Individual split units create maintenance headaches and architectural clutter. Rooftop units offer limited zoning flexibility.
Variable Refrigerant Flow (VRF) systems solve these challenges. By intelligently varying refrigerant flow to multiple indoor units, VRF delivers precise zone control, exceptional energy efficiency, and design flexibility—all from a single, scalable system.
At Vestar, we engineer and manufacture commercial-grade VRF split systems for the North American market. With nearly 20 years of HVAC OEM/ODM experience, we serve as a strategic partner for mechanical contractors, project developers, and HVAC brands seeking reliable, code-compatible VRF solutions.
| System Type | Operation | Best Applications | Efficiency Benefit |
