Plan Your Project With UsFrequently Ask Questions
-
What types of commercial HVAC equipment do you install and retrofit?
We handle a full range of commercial infrastructure, including packaged rooftop units, chillers, cooling towers, AHUs, VRF/VRV systems, and pump packages.
-
How do you handle equipment replacements in active, occupied buildings?
We design a phased shutdown and installation strategy, often utilizing crane lifts during off-hours or weekends to minimize disruption to your tenants, employees, or production lines.
-
Can a retrofit actually lower my monthly utility bills?
Yes. Upgrading from aging, inefficient chillers or RTUs to modern, high-efficiency equipment—combined with proper sizing and VRF technology—typically results in substantial energy savings.
