HVAC Services in Manhattan
Dezier Air provides residential and commercial HVAC service across Manhattan — from prewar co-ops on the Upper East and Upper West Sides to high-rise condos in Midtown, FiDi, and Hudson Yards, brownstones in Harlem and Washington Heights, and commercial spaces in Chelsea, SoHo, and the Flatiron District. We handle repair, maintenance, installation, and performance optimization with building-aware scheduling, documented work, and clean execution.
HVAC in Manhattan Buildings
Manhattan work has its own constraints — limited mechanical space, service-elevator windows, roof and facade access rules, and board or management approvals before anything starts.
- Prewar co-ops and condos: steam heat, radiator issues, through-wall and PTAC units
- High-rise buildings: VRF and split systems, riser access, condensate routing
- Brownstones and townhouses: ducted systems, mini-splits, heat pump conversions
- Commercial spaces: rooftop units, retail and restaurant ventilation, off-hours service
- Building coordination: COIs, approved contractor requirements, and scheduled access windows
