HVAC Engineering in Bellevue, WA

Bellevue's downtown has become a second urban core for the Seattle region — Amazon and T-Mobile footprints, a forest of new residential and office towers, and East Link light rail now connecting it to Seattle, all on the east side of Lake Washington.

What we design

Heating, cooling, ventilation, and controls — one coordinated mechanical design for Bellevue high-rise residential towers. Torch delivers load calcs, equipment schedules, duct layouts, and ASHRAE 90.1 documentation that the Bellevue building department reviewers approve, backed by Apex Grid Engineering's licensed engineers.

• Heating and cooling load calculations for Bellevue high-rise residential towers using a marine climate with wet winters design conditions — envelope, occupancy, and ventilation loads modeled so equipment is sized right, not oversized by habit.
• Ventilation for Bellevue transit-oriented development projects is designed for the actual occupancy — conference-heavy floors, kitchens, and locker rooms each get their own air-change logic, not one blanket rate.
• Energy modeling and Title-24-style documentation for Bellevue high-rise residential towers: our compliance forms match the drawings, so the Bellevue building department energy review doesn't generate a second correction cycle.
• Bellevue, WA contractors call Torch when the schedule is tight: fast mechanical quotes, coordinated drawings, and a PE stamp the Bellevue building department accepts.
• Our Bellevue duct designs coordinate above the ceiling before construction starts — transit-oriented development projects can't afford the field reroutes that come from uncoordinated shop drawings.
