Customer Testimonials
Brooklyn Hospital Center
Chief Facilities Engineer
“GRR’s retrofit team completed our 30-year-old AHU upgrade in a live hospital environment without interrupting a single OR schedule. Their planning, infection-control measures, and precision balancing made the transition seamless. Energy readings show a 27% reduction in fan power — exactly what was projected.”
Columbia University
Director of Capital Projects
“Our research labs needed reliable airflow and redundancy upgrades. GRR’s engineers understood the constraints of our older infrastructure and integrated EC fan arrays that now tie directly into our BMS. The project finished ahead of schedule, and the acoustics improvement was immediately noticeable.”
NewYork-Presbyterian
HVAC Operations Manager
“When one of our main air-handling units failed unexpectedly, GRR mobilized overnight with a modular fan-array replacement. Within 48 hours, full airflow was restored. Their technical expertise and coordination with our in-house team were outstanding — truly professionals you can count on in critical environments.”
