HVAC Engineering in Oklahoma City, OK

Oklahoma City is the state capital and an energy town, with Devon Energy's tower downtown, Tinker Air Force Base, and the MAPS-funded downtown renaissance around Scissortail Park and the streetcar. Tornado Alley weather and red-bed clay soils are the design constants.

What we design

Heating, cooling, ventilation, and controls — one coordinated mechanical design for Oklahoma City government and civic buildings. Engides delivers load calcs, equipment schedules, duct layouts, and ASHRAE 90.1 and the IECC documentation that the Oklahoma City building department reviewers approve, backed by Apex Grid Engineering's licensed engineers.

  • Heating and cooling load calculations for Oklahoma City government and civic buildings using tornado-alley extremes design conditions — envelope, occupancy, and ventilation loads modeled so equipment is sized right, not oversized by habit.
  • Ventilation per ASHRAE 62.1 for Oklahoma City government and civic buildings: outdoor-air rates by occupancy, dedicated outdoor-air systems where they pay off, and exhaust make-up that keeps the building balanced.
  • Controls sequences written for the Oklahoma City operator, not just the submittal: economizer changeover, morning warm-up, and unoccupied setback logic that actually gets programmed.
  • What slows Oklahoma City, OK HVAC permits: ventilation math that doesn't add up and equipment schedules missing electrical data. We cross-check both before submitting to the Oklahoma City building department.
  • Ductwork designed for low static and quiet operation in Oklahoma City government and civic buildings: trunk-and-branch layouts, proper aspect ratios, and sealing specs that meet ASHRAE 90.1 and the IECC leakage limits.
