About NYC Custom HVAC
25 Years of NYC HVAC Expertise
NYC Custom HVAC was built on a simple premise: New York buildings have unique requirements that off-the-shelf equipment can't satisfy. We source, specify, and supply precision HVAC equipment matched to the sleeve dimensions, electrical requirements, and load calculations of each project.
As authorized dealers for Thru-Wall, Aerosys, AboveAir, National Comfort Products, and Jaga, we carry the full range of solutions for NYC's residential and light commercial market — from a single co-op unit to a complete high-velocity system spanning 20 rooms.
