About Dezier Air
A New York City HVAC company built at the intersection of engineering, technical training, and real-world building experience — serving residential and commercial clients across NYC.
Dezier Air approaches HVAC as an engineered system — not just equipment installation. We design, install, and service systems with an emphasis on clean execution, clear communication, and long-term performance.
Our work begins long before tools come out. From legacy buildings to new construction, our team plans around access constraints, code requirements, and long-term maintenance — so systems perform as intended and service stays predictable.
We support complex residential environments (co-ops, condos, multi-family buildings) and commercial properties where operational continuity, documentation, and system awareness matter.
Technical & Academic Foundation
Members of our leadership and technical team bring training from MIT, NYU, and John Jay College, alongside hands-on technical education and field-based apprenticeship experience.
This foundation informs how we think about load calculations, controls, energy systems, and long-term system behavior — especially in dense NYC environments.
Our technicians and engineers complete ongoing manufacturer courses, technical programs, and certifications. We value documentation, commissioning, and repeatable processes — not shortcuts.
Every project benefits from clear notes, protected work areas, and building-aware planning.
Partners, Certifications & Academic Foundations
Dezier Air participates in select manufacturer programs, including Mitsubishi Electric Diamond Contractor pathways and preferred dealer relationships with Samsung and LG. These partnerships support proper system design, commissioning, and warranty-aligned installation standards.
Our team blends academic training with real field execution — bringing planning discipline, technical rigor, and NYC building experience into every install, service call, and long-term maintenance plan.
Our Team
Dezier Air is powered by a multidisciplinary team of engineers, lead technicians, installers, and operations staff.

We prioritize collaboration, accountability, and continuous improvement — ensuring every job benefits from consistent standards.
