UFAD & Trench Heating

Improve Indoor Air Quality with Innovative Solutions from AirFixture

HIGHMARK is the official AirFixture representative in New York City and New York, delivering advanced underfloor air distribution (UFAD) and trench heating systems designed to improve energy efficiency, indoor air quality, and design flexibility.

UFAD leverages raised access floors to deliver conditioned air directly through floor diffusers. Compared to overhead VAV systems, UFAD improves air quality, lowers installation costs, and can cut fan energy by up to 30%. It also frees up mechanical space and provides more consistent comfort for occupants.

AirFixture provides a complete range of UFAD technologies, including wireless and VAV diffusers, compact Air Tower air-handling units, and underfloor fan-powered VAV terminal units. These systems are engineered to maximize efficiency and adaptability in modern buildings.

AirFixture’s trench heaters are sleek, low-profile perimeter systems that deliver quiet, efficient comfort along building envelopes. Available in heating-only, cooling-only, or combined options, they integrate seamlessly into architectural designs without sacrificing performance.

By combining HIGHMARK’s local expertise with AirFixture’s innovative UFAD and trench heating solutions, clients gain high-performance HVAC systems that reduce energy use, enhance occupant comfort, and support modern, sustainable building designs.
