Commercial HVAC Services in New York City
One commercial mechanical contractor across all five boroughs — rooftop units, chillers, boilers, VRF, and building controls for office towers, hotels, restaurants, retail, and mixed-use properties. Com+ Mechanical dispatches 24/7 from a Manhattan base, serving Manhattan, Brooklyn, Queens, the Bronx, and Staten Island.
HVAC Realities Commercial Buildings Face in NYC
Aging steam and hydronic plants in prewar buildings
A large share of NYC's mixed-use and loft stock — across Manhattan, Brooklyn, and parts of Queens and the Bronx — still runs on original-vintage steam or hot-water heating. Failed traps, short-cycling burners, uneven heat by floor, and decades of patchwork repairs are routine, and cellar access in an occupied building is rarely simple.
Rooftop and high-rise access constrained by streets and tenants
Setting or servicing rooftop equipment in NYC means crane lifts over live streets, DOT occupancy permits, narrow rigging paths, freight-elevator scheduling, and after-hours work permits. A contractor unfamiliar with the boroughs underestimates every one of those costs and delays.
Local Law 97 carbon-emissions exposure
Most NYC buildings over 25,000 square feet now face tightening carbon-emissions limits under Local Law 97, and aging chillers, boilers, and RTUs are usually the largest contributor. Capital-planning replacements and electrification phases need to start years before deadlines hit.
Restaurant and retail make-up air and ventilation
Commercial kitchens, ground-floor restaurants, and high-traffic retail across the boroughs routinely overwhelm undersized make-up air and exhaust systems, causing negative pressure, comfort complaints, and code issues. These problems compound through summer and grease season.
Tenant comfort across mixed-use stacking
When retail at grade, offices in the middle, and residential on top share a single building and a patchwork of HVAC systems, balancing comfort and managing complaints requires a contractor who can service every system rather than passing off the ones outside their specialty.
Commercial HVAC Across All Five Boroughs
New York City is not one HVAC market — it's five. A Class A office tower in Midtown Manhattan runs on central chiller plants, cooling towers, and a BAS sequencing dozens of air handlers. A prewar mixed-use building in Brooklyn or the Bronx is heated by a cellar steam plant that's been patched for fifty years. A restaurant in Queens or a flagship storefront in SoHo lives or dies by a packaged rooftop unit and a make-up air system the kitchen overwhelmed years ago. Com+ Mechanical works across all of it. We service, repair, maintain, and replace commercial RTUs, air- and water-cooled chillers, commercial steam and hydronic boilers, cooling towers, VRF/VRV systems, air handlers, and the controls that tie them together — for property managers, building owners, and facility directors who need one accountable vendor across a portfolio instead of a different contractor at every site. Operating from a Manhattan office and dispatching across the metro, our crews are familiar with NYC's realities: DOB permitting, freight-elevator windows, after-hours roof access, crane lifts over live streets, co-op and condo board rules, and Local Law 97 carbon-emissions pressure that's only getting tighter. Whether you manage a single landmark building in Manhattan, a restaurant group across Queens and Brooklyn, or a 30-site retail portfolio across the boroughs, the goal is the same: keep tenants conditioned, keep equipment running, and plan capital work before it becomes an emergency call.
Commercial HVAC Services Across NYC
Why NYC Property Managers Choose Com+
Our Simple Process
From call to comfort in 4 easy steps
Building & Equipment Walk
We walk the building with your property manager or facilities lead, inventory the mechanical systems, and confirm access, controls, and operational hours before quoting anything.
Written Scope & Proposal
You get a fixed written proposal — repair scope, parts, access plan, and schedule — before any work begins. No surprises after the crane arrives.
Staged Around Tenants
Work is scheduled around tenant hours, freight-elevator windows, and building rules. We coordinate with property management, security, and other trades.
Documented Service Records
Every visit produces a written condition report on the equipment we touched, so your file supports capital planning and Local Law 97 documentation.
Types of Systems We Install

Frequently Asked Questions
Get answers to common questions about our services
Which boroughs and neighborhoods does Com+ Mechanical serve?
We serve commercial buildings across all five NYC boroughs — Manhattan, Brooklyn, Queens, the Bronx, and Staten Island — including Midtown, the Financial District, Hudson Yards, Chelsea, the Flatiron, SoHo, Downtown Brooklyn, Long Island City, Astoria, Flushing, and the surrounding metro. We dispatch from a Manhattan office near Times Square.
How fast can you respond to an emergency in NYC?
We provide 24/7 emergency response across all five boroughs for no-cooling, no-heat, and equipment-down situations, and our Manhattan base helps us mobilize quickly into the metro. When a chiller, boiler, or rooftop unit goes down during peak season, we can deploy and put temporary measures in place while a permanent repair is scoped.
Can you maintain HVAC across a portfolio of NYC buildings?
Yes. We regularly support property managers and owners with multiple NYC buildings, acting as one accountable vendor across every system — rooftop units, chillers, boilers, VRF, and controls — with consistent service records and reporting. You get one point of contact and standardized preventive maintenance across the whole portfolio.
How can you help our building with Local Law 97?
NYC Local Law 97 sets tightening carbon-emissions limits on most buildings over 25,000 square feet, and aging chillers, boilers, and rooftop units are often the largest contributors. We assess where your building stands and recommend high-efficiency equipment, electrification options, and controls improvements that lower carbon intensity and operating cost — phased around your capital plan instead of an all-at-once replacement.
Do you work on commercial kitchen and restaurant HVAC?
Yes. We service rooftop units, make-up air systems, exhaust, and ventilation for ground-floor restaurants and commercial kitchens across NYC, where undersized or aging systems routinely cause negative pressure, comfort complaints, and code issues — especially during peak summer service.
Do you serve specific borough markets directly?
Yes — we have dedicated information for each borough and major submarket. See our pages for Manhattan, Brooklyn, Queens, the Bronx, Staten Island, Midtown, the Financial District, Hudson Yards, Downtown Brooklyn, and Long Island City for borough- and neighborhood-specific detail.
