    Commercial HVAC for Property Management Portfolios Across the NYC Metro

    Property management companies don't run one kind of building — you run a mixed portfolio, and every site has a different mechanical fleet: rooftop units over a retail tenant, a chiller-and-BAS office floor, a steam or hot-water boiler in a mixed-use property, and exhaust and makeup air everywhere in between. Com+ Mechanical is the single HVAC partner that covers all of it, with preventive maintenance, repairs, capital retrofits and 24/7 emergency response on one agreement and one point of contact. We serve property managers, asset managers, owners and facilities leads across the five boroughs, Nassau, Westchester, northern New Jersey and Stamford, CT.

    HVAC Challenges in Property Management Portfolios

    A different contractor at every building

    When each property has its own HVAC vendor, you get inconsistent paperwork, no portfolio-wide view of equipment condition, and finger-pointing when a job spans trades. Consolidating onto one partner gives you standardized reporting and a single point of accountability across every site.

    Tenant complaints that land on the property manager first

    A hot floor, a cold suite, or a noisy rooftop unit becomes your problem the moment a tenant calls — often with a lease clause behind it. Without priority response and a documented history, comfort complaints turn into chargeback disputes and renewal friction.

    Surprise capital failures with no budget warning

    A compressor or heat exchanger that fails with no notice forces an emergency capital outlay you didn't forecast. Aging equipment across many buildings, tracked by no one, means the next five-figure replacement is always a surprise instead of a planned line item.

    Confusion over landlord-versus-tenant HVAC responsibility

    Leases split who maintains and replaces what — base-building systems versus tenant supplemental units — and the line is often unclear in the field. Servicing the wrong unit, or missing one you're contractually obligated to maintain, creates billing disputes and deferred-maintenance liability.

    Deferred maintenance catching up at the worst time

    Skipped filter changes, fouled coils and untuned combustion quietly raise energy spend and shorten equipment life across a portfolio until failures cluster — usually during a heat wave or cold snap when response is slowest and costliest.

    No documentation for ownership, lenders or Local Law 97

    Asset managers, lenders and insurers want a service history, and covered NYC buildings face Local Law 97 emissions reporting. Scattered invoices from multiple vendors don't produce the documented, benchmarkable record those stakeholders expect.

    One HVAC Partner for a Mixed Commercial Portfolio

    Managing HVAC across a portfolio is a different problem than maintaining a single building. Your assets aren't standardized — one property runs gas/electric rooftop units, the next a central chiller plant with VAV and a building automation system, another a boiler with perimeter heat, and almost all of them have tenant exhaust, makeup air and ventilation that the lease makes you responsible for. Spread that across multiple buildings and you end up juggling a different contractor per site, inconsistent paperwork, and no clear view of which equipment is about to fail or eat your capital budget. Com+ Mechanical replaces that with one accountable vendor across the whole portfolio: a tagged asset list for every building, a documented preventive schedule sized to each system, consolidated per-building reporting, and the same crew for routine PM, break-fix repairs, planned retrofits and after-hours emergencies. We work the way property teams actually operate — coordinating COIs, roof and mechanical-room access, tenant notice, and the landlord-versus-tenant HVAC responsibility split written into your leases — and we frame our reporting around OpEx predictability, capital planning and Local Law 97 exposure so you can defend decisions to ownership. The goal is fewer surprise failures, fewer tenant complaints, and a single relationship instead of a binder full of phone numbers.

    Our Simple Process

    From call to comfort in 4 easy steps

    1

    Portfolio assessment & asset inventory

    We walk each building — roofs, mechanical rooms and tenant spaces — and inventory every HVAC unit by make, age and condition, documenting access requirements and which systems are base-building versus tenant responsibility. This becomes the tagged asset list behind everything we do.

    2

    Criticality review & program design

    We rank systems by consequence of failure — which units, if down, mean tenant complaints, lost revenue or a compliance issue — and design a preventive schedule and coverage level per system, so high-risk equipment gets richer coverage instead of one flat plan across the portfolio.

    3

    Scheduled service, repairs & capital work

    We execute the preventive calendar, handle break-fix repairs and tenant fit-out work, and quote planned retrofits and replacements with repair-versus-replace guidance — all under one relationship, with COI and tenant-access coordination handled for each visit.

    4

    Reporting, capital planning & review

    After every visit you get documented condition reports with photos and logged readings, and on a recurring basis a portfolio review with equipment lifecycle forecasts, budget guidance and Local Law 97-relevant findings — so you can plan capital and defend decisions to ownership.

    Types of Systems We Install

    Packaged Rooftop Units (RTUs) & Split Systems

    The most common configuration over retail, restaurant and single-tenant commercial spaces in a portfolio — gas/electric and heat-pump packages, plus ducted and ductless splits serving individual suites.

    • Gas-heat and heat-exchanger safety diagnostics
    • Economizer, refrigeration and control service
    • Tenant-suite split and supplemental-unit support

    Central Chiller & Boiler Plants

    Larger office, mixed-use and high-rise properties run central plants — chillers with cooling towers for cooling, and steam or hot-water boilers for heat — serving multiple floors and zones through air handlers and VAV.

    • Chiller, tower and pump service and water treatment coordination
    • Steam and hot-water boiler maintenance and combustion tuning
    • Air-handler and VAV troubleshooting across zones

    VRF/VRV Systems & Building Automation Controls

    Modern fit-outs and electrification strategies increasingly use VRF/VRV with zone control, tied together by a building automation system that schedules and monitors equipment across the building.

    • VRF/VRV zone-control and refrigerant management
    • BAS programming, sequence verification and sensor calibration
    • Remote scheduling and alarm response

    The Com+ Mechanical Difference for Property Teams

    Whole-portfolio coverage under one relationship

    Rooftop units, chillers, boilers, cooling towers, air handlers, VRF and controls across every building can sit under a single agreement, so nothing falls through the cracks between trades or sites.

    Built for how property managers operate

    Single point of contact, documented reporting after every visit, and COI, roof access and tenant-notice coordination handled for you — including the base-building versus tenant-unit distinction your leases define.

    Reporting tied to budgets and compliance

    We frame condition and runtime findings around OpEx predictability, capital forecasting and Local Law 97 emissions exposure — not just a checklist of parts replaced — so the data is useful to ownership and lenders.

    Maintenance that prevents the next emergency

    Scheduled preventive work catches worn belts, fouled coils and drifting refrigerant charge before they become after-hours failures and tenant complaints, reducing both downtime and surprise spend across the portfolio.

    Transparent Pricing

    No fees. No surprises. Just honest service.

    Frequently Asked Questions

    Get answers to common questions about our services

    Can you cover every building in our portfolio under one agreement?

    Yes. Consolidating a mixed portfolio onto one vendor is exactly what we're built for. We put every building's equipment on a single tagged asset list under one master relationship, with consistent per-building reporting, coordinated scheduling and one point of contact across the five boroughs, Nassau, Westchester, northern New Jersey and Stamford. You can place mission-critical buildings on richer coverage and lower-risk sites on a lighter plan, all under the same agreement.

    Do you offer 24/7 emergency response, and is there a guaranteed response time?

    Yes — HVAC failures don't wait for business hours, so we provide 24/7 emergency commercial response across the NYC metro, with agreement holders dispatched ahead of non-contract calls. Preventive coverage also reduces how often you need emergency service in the first place by catching faults before they fail.

    How do you handle the split between base-building and tenant HVAC responsibility?

    We document, building by building, which systems are base-building (your responsibility) versus tenant supplemental units, based on your leases, and tag them on the asset list so the right equipment is serviced and billed to the right party. That prevents the common problem of servicing a unit you're not obligated to maintain — or missing one you are — and keeps maintenance and replacement responsibility clear for both you and your tenants.

    Can you help us plan and budget for capital HVAC replacements?

    Yes. Part of a portfolio program is an equipment lifecycle view: we track the age and condition of each unit and forecast which are approaching end of life, so replacements become planned capital line items instead of surprise emergency outlays. Our reporting is built to help you separate CapEx from OpEx and defend the timing of major replacements to ownership and asset management.

    How does working with you help with Local Law 97 and ventilation compliance?

    For covered NYC buildings, equipment kept on a documented preventive schedule runs at its rated efficiency — clean coils, tuned combustion and correct control sequences all lower energy use, which directly affects your emissions and Local Law 97 exposure. We produce documented condition and runtime reporting you can use for benchmarking, frame efficiency retrofits around emissions targets, and verify ventilation and exhaust performance so occupied spaces meet applicable code.

    What types of HVAC equipment do you service across a portfolio?

    Because portfolios are heterogeneous, we service the full range commonly found across commercial buildings: packaged rooftop units, split and VRF/VRV systems, central chiller plants and cooling towers, steam and hot-water boilers, air handlers and VAV systems, and the building automation and controls that tie them together — from manufacturers including Carrier, Trane, York, Daikin Applied, AAON, Mitsubishi Electric, Cleaver-Brooks and Weil-McLain. One vendor covers every system type rather than a separate specialist per trade.
