HVAC Engineering in Manchester, NH

Manchester anchors southern New Hampshire's construction market as the state's largest city — the historic Amoskeag Millyard now houses tech offices and UNH Manchester, with Elliot Hospital and Catholic Medical Center driving healthcare work and Southern New Hampshire University expanding institutional campuses.

What we design

Heating, cooling, ventilation, and controls — one coordinated mechanical design for Manchester industrial & manufacturing facilities. Torch delivers load calcs, equipment schedules, duct layouts, and the IECC documentation that the Manchester building department reviewers approve, backed by Apex Grid Engineering's licensed engineers.

• What slows Manchester, NH HVAC permits: ventilation math that doesn't add up and equipment schedules missing electrical data. We cross-check both before submitting to the Manchester building department.
• DDC controls design for Manchester healthcare & medical facilities — points lists, sequences of operation, and integration with lighting so the building performs after commissioning, not just on paper.
• Manchester, NH contractors call Torch when the schedule is tight: fast mechanical quotes, coordinated drawings, and a PE stamp the Manchester building department accepts.
• Manchester healthcare & medical facilities need equipment that handles cold, snowy winters without short-cycling: we select and stage systems for part-load efficiency, not just design-day capacity.
• Ductwork designed for low static and quiet operation in Manchester industrial & manufacturing facilities: trunk-and-branch layouts, proper aspect ratios, and sealing specs that meet the IECC leakage limits.
