HIGHMARK & Addison: Leading in DOAS Innovation
Innovative solutions in Comfort & Air Solutions
HIGHMARK is the official Addison representative in New York City & New Jersey, delivering solutions for safer, healthier, and more productive indoor environments. Addison, an innovation leader since 1949, helped define HVAC comfort with the first split-system air conditioner and the first commercially available Dedicated Outdoor Air System (DOAS). Their DOAS lineup including the versatile PR Series, modular MA/MC splits, compact AK Series, LC Series, and MI Indoor Vertical units is built for flexibility, energy efficiency, and long-term performance. These systems decouple ventilation from heating and cooling loads to improve humidity control, reduce installation and operational costs, and increase energy savings.
Addison also offers advanced air to air DOAS heat pumps like the AK 1 Series, designed for compact rooftop installations. These units feature multiple coil configurations, precise sensible and latent load management through CoilMatrix, and seamless compatibility with existing footprints. By integrating heat pump technology into their DOAS systems, Addison improves indoor air quality, system flexibility, and building efficiency across the NYC metro area. This supports HIGHMARK’s mission to deliver high-performance, climate-ready solutions for the built environment.
