Healthier Air, Stronger Performance

High‑rise environments require clean, stable air to support occupant comfort and productivity. We apply source control, adequate ventilation, and effective filtration strategies—paired with smart controls—to maintain target temperatures, humidity, and CO2 levels. Our team designs DOAS and VRF/central plants to deliver outside air efficiently while meeting energy codes, helping your building balance comfort, indoor air quality, and operating cost.

Factory‑Trained, Brand‑Agnostic Expertise

Our engineers trained at manufacturer facilities including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That means accurate selections, proper refrigerant piping, oil return management, and reliable commissioning for VRF systems—plus proven best practices for chillers, boilers, and air handlers from a range of OEMs. We specify what’s right for your tower, not just a single brand.

Compliance Without Compromise

From Title 24 acceptance testing to smoke control sequences and stairwell pressurization, we engineer and verify the details that matter in high‑rise life safety and inspections. Our documentation, O&M manuals, and training sessions equip your facilities team to operate systems confidently from day one.
