A guestroom that won't cool at 2 a.m. is a comp, a bad review, and a front-desk fire drill. Com+ Mechanical keeps hotels, boutique properties, and hospitality buildings comfortable and compliant across the five boroughs, Nassau, Westchester, northern New Jersey, and Stamford. From guestroom PTACs to central plants, kitchen makeup air, and cooling-tower water management, we serve the equipment your guests, kitchens, and event spaces depend on — 24/7.
A failed PTAC compressor, frozen coil, clogged condensate drain, or dead fan motor turns a sold room into a comp and a one-star review. Across a full floor of aging units, complaints cluster fast. We diagnose the actual fault and keep a repair-or-swap plan ready so the front desk isn't relocating guests at midnight.
Undersized dehumidification, oversized units that short-cycle, blocked condensate, and poor ventilation leave rooms damp and smelling musty — especially on shoulder-season days and in below-grade or street-facing rooms. Damp guestrooms drive complaints, mold remediation costs, and rooms taken out of inventory.
In WSHP and four-pipe fan-coil buildings, a failing circulation pump, loop temperature drift, fouled heat exchanger, or stuck valve doesn't affect one room — it knocks out heating or cooling for an entire vertical stack or wing at once. These failures need fast, central-plant-level diagnosis, not a room-by-room guess.
When makeup air falls behind exhaust, the kitchen goes negative — doors are hard to open, the dining room gets warm, and grease and food odors migrate into corridors and the lobby. Balanced makeup air and exhaust protect both the line cooks and the guest experience during peak banquet service.
NYC registers and inspects cooling towers, and a lapse in water management or a Legionella concern is a public-health and reputational risk no hotel wants attached to its name. Towers also drive comfort for the whole property when summer demand and a full house hit at once.
Large hotels carry significant emissions, and dated PTACs, gas heat, and inefficient plant push energy costs and Local Law 97 penalty risk upward. Replacing equipment blind — without a plan that respects occupancy and capital cycles — is how properties overspend and still miss targets.
Hotels never close. Every guestroom is a micro-climate a paying guest controls, the lobby and ballroom run on different systems than the rooms, the kitchen and laundry push their own loads, and a single unhappy night turns into an online review that costs you future bookings. That makes hospitality HVAC unlike any other building type — you're managing comfort, ventilation, humidity, and uptime across hundreds of independent zones at once. Com+ Mechanical is a commercial-only contractor serving the NYC metro. We maintain, repair, retrofit, and replace the full stack hospitality properties run: through-the-wall PTAC and PTHP units, water-source heat pump (WSHP) loops, four-pipe fan-coil systems, rooftop units and air handlers for public spaces, kitchen makeup air and exhaust, domestic hot water, and cooling towers. We plan work around occupancy and sold-out nights, document everything for your owner and brand, and stand behind guest comfort with 24/7 response — because in this business, downtime is measured in refunds and ratings, not just degrees.
From call to comfort in 4 easy steps
We survey guestroom units, central plant, public-space systems, kitchen ventilation, and towers, review your complaint history and capital plan, and map every system with its condition and risks — coordinating COIs, access, and house rules up front.
You get a documented plan that separates urgent fixes from planned maintenance and capital projects, sequenced around sold-out nights, group blocks, banquet calendars, and your PIP or renovation cycle.
We deliver maintenance, repairs, retrofits, and floor-by-floor change-outs with minimal guest disruption — keeping rooms in inventory and event spaces running, and coordinating with your engineering and front-of-house teams.
After each visit we document what was done, what's trending, and what's next — equipment logs, photos, and recommendations that support brand standards, owner reporting, and compliance, with priority response between visits.
Through-the-wall packaged terminal units that condition individual guestrooms — the workhorse of most NYC hotels and the system guests interact with directly.
Central loop systems serving guestroom stacks and public areas via WSHP units or four-pipe fan-coils, tied to boilers, cooling towers, and circulation pumps.
Rooftop units, AHUs, and DOAS conditioning lobbies, ballrooms, meeting space and restaurants — plus makeup air and exhaust for hotel kitchens and banquet operations.
We service hotel equipment day in and day out — PTACs, WSHP loops, fan-coils, makeup air, and towers — and we understand that a guestroom is a revenue unit and a review waiting to happen, not just a thermostat.
Quiet, comfortable rooms, balanced public spaces, and kitchens that don't push odors to the lobby. We tune to the guest experience and brand standard, not just to a setpoint.
One accountable vendor for a single boutique property or a multi-hotel portfolio across the five boroughs, Long Island, Westchester, northern NJ, and Stamford — consistent documentation across every site.
Every repair and program is built to reduce guest-facing emergencies, protect room inventory, and extend equipment life — so failures don't surface in front of your guests.

Both. We maintain and repair through-the-wall PTAC and PTHP units and run floor-by-floor change-out programs, and we service the central systems behind public spaces and guest stacks — water-source heat pump loops, four-pipe fan-coils, rooftop units, air handlers, and pumps. One vendor covers the whole property.
Yes. We service hotel cooling towers and support ASHRAE 188 water-management practices and NYC cooling-tower registration and inspection requirements, which are a real public-health and reputational concern for any hospitality property.
Large hotels carry meaningful emissions, and aging PTACs, inefficient gas heat, and dated plant raise both energy spend and Local Law 97 penalty exposure. We assess your equipment and show how phased replacements, controls, and efficiency upgrades reduce energy use and emissions — sequenced around occupancy and your capital plan so you're not overspending to hit targets.
