HVAC Contractors & Engineers

System sourcing for HVAC contractors and engineering firms — from chillers and VRF to AHUs and fan coils, matched to real load calculations, not sales pressure.

Common Challenges

Getting HVAC system selection right requires matching system type, capacity, and configuration to a building's actual load, zoning, and ventilation requirements — a decision that's expensive to get wrong. Contractors and engineers also need a sourcing partner who can move from confirmed specification to actual delivery without the project stalling.

Relevant Products

Chillers, VRF systems, AHUs, rooftop package units, ducted split systems and fan coil units, sourced to match confirmed project specifications.

NAD's Approach

NAD's HVAC engineering tools (load calculator and full engineering toolkit) are available to help narrow down the right system type before a formal quote — then NAD sources and coordinates delivery against that confirmed specification.
