One Maintenance Agreement for Every HVAC System in Your Building
Most buildings run a patchwork of rooftop units, chillers, boilers, air handlers and controls — often under three different vendors. Com+ Mechanical puts your entire mechanical plant under one preventive maintenance agreement, with scheduled service, documented inspections and 24/7 priority response. One contract, one point of contact, one log of everything that touches your equipment — across a single property or an entire portfolio.
What Preventive Maintenance Catches Before It Becomes a Failure
Clogged filters and slipping belts starving airflow
Loaded filters and worn, mis-tensioned belts drop airflow, overwork blower motors and trip high-static or freeze-stat faults. Scheduled changes keep CFM where the design intended and stop a part from taking out a motor.
Fouled coils and condensers driving up energy use
Dirty condenser and evaporator coils raise head pressure and approach temperature, forcing compressors to run longer and hotter. Planned coil cleaning restores capacity and cuts kWh — and the runtime that ages compressors.
Slow refrigerant leaks bleeding capacity
Small leaks at flare fittings, Schrader cores and coil U-bends lower charge gradually until a floor stops cooling on the hottest day. Routine superheat/subcooling and leak checks find them while they're cheap to fix and properly logged.
Combustion drift and dirty heat exchangers on the boiler plant
Burners fall out of tune, flame sensors foul and heat exchangers soot up — wasting gas and risking a cracked exchanger or nuisance lockout mid-winter. Combustion analysis and flame-safeguard testing catch it before a no-heat call.
Scale, fouling and biological growth in condenser water
Untreated tower and condenser-water loops scale up, lose heat-transfer efficiency and create Legionella risk. Coordinated water treatment and tower service protect both the chiller plant and building occupants.
Drifting sensors and overridden schedules in the BAS
Failed or uncalibrated sensors, forgotten manual overrides and stale schedules quietly run equipment when the building is empty — or fight heating against cooling. A control-point review re-aligns the system to how the building is actually occupied.
Preventive Maintenance Built for the Whole Building, Not One Unit
A commercial building rarely has one kind of HVAC equipment. A typical NYC property mixes packaged rooftop units, an air-cooled or centrifugal chiller, a gas or steam boiler plant, air handlers and fan-coils, VRF or split systems on tenant floors, exhaust and make-up air, pumps, and a building automation system tying it together. Com+ Mechanical covers all of it under a single preventive maintenance agreement scoped to your actual equipment list. We build a site-specific task calendar — filter and belt changes, coil cleaning, refrigerant and combustion checks, water-treatment coordination, control-point verification and seasonal changeovers — then perform it on schedule and document every visit. The goal is simple: fewer emergency failures, lower energy use, longer equipment life, and a clean paper trail for ownership, tenants and compliance. One agreement replaces the guesswork of calling a different contractor every time something different breaks.
What a Com+ Maintenance Agreement Covers
Why a Single Maintenance Agreement Pays Off
Our Simple Process
From call to comfort in 4 easy steps
Equipment survey & assessment
We walk the building — roof, mechanical rooms, tenant spaces — and inventory every piece of HVAC equipment, its make, age, condition and access requirements.
Scoped agreement & task calendar
We build a site-specific PM scope and visit frequency for each system, with a clear written quote. You see exactly what gets serviced and when before signing.
Scheduled service & documentation
We perform each visit on schedule, coordinate access with building staff and tenants, and leave a documented report with photos and any findings after every trip.
Reporting & repair recommendations
You get ongoing condition reporting, flagged items with repair-vs-replace guidance, and priority response when something does need attention between visits.
Types of Systems We Install
Air-Side Equipment
Rooftop units, air handlers, fan-coils and VRF systems that move and condition air throughout the building.
- •Filter, belt and bearing service
- •Coil cleaning and airflow verification
- •Economizer and damper checks
Central Plant (Chillers & Boilers)
Chillers, cooling towers and the heating plant that generate the building's hot and chilled water.
- •Combustion analysis and flame-safeguard testing
- •Refrigerant and approach-temperature checks
- •Water-treatment and tower coordination
Controls & Building Automation
The BAS and field devices that schedule and sequence every system in the building.
- •Sensor calibration
- •Setpoint and schedule verification
- •Alarm and override review
Why Property Managers Put Their Portfolio With Com+
We cover the whole mechanical plant
Rooftop units, chillers, boilers, towers, air handlers, VRF and controls — all under one agreement, so nothing falls through the cracks between vendors.
Built for property managers and facilities
Single point of contact, clear documentation, COI handling and coordination with your building staff and tenants on every visit.
One agreement across an entire portfolio
Whether it's one building or dozens across the five boroughs and metro, you get consistent scope, scheduling and reporting under a single contract.
Maintenance tied to energy and compliance
Our PM reporting supports Local Law 97 benchmarking and efficiency goals, with findings framed around runtime, energy and emissions — not just broken parts.
Transparent Pricing
No fees. No surprises. Just honest service.
Building Assessment & Equipment Survey
A full walkthrough and asset inventory to scope the right maintenance program for your building.
- On-site survey of all HVAC equipment
- Make, age, condition and access documented
- Tagged asset list and recommended PM frequencies
- Written scope and proposal — no obligation
Whole-Building Preventive Maintenance Agreement
Scheduled preventive maintenance across every system in the building, fully documented.
- Planned visits for air-side, refrigeration and heating equipment
- Coil, filter, belt, combustion and control service
- Priority emergency response between visits
- Documented reports with photos after every visit
Portfolio Maintenance Program
One agreement covering HVAC maintenance across multiple buildings and sites.
- Consistent PM scope across every property
- Portfolio-wide scheduling and single point of contact
- Consolidated reporting and asset tracking
- Capital-planning input for aging equipment
Pricing shown is a structure, not a quote. Every maintenance agreement is scoped in writing after an on-site equipment survey, since cost depends on the number and type of units, building access and visit frequency.

Frequently Asked Questions
Get answers to common questions about our services
What does annual VRF maintenance cost?
Maintenance is priced by indoor unit count and visit frequency. Most commercial buildings run a 2- or 4-visit plan covering filter and coil cleaning, refrigerant charge verification, controls checks, and priority emergency response. VRF systems reward maintenance — skip it and efficiency drifts, warranty claims get denied. Request a maintenance quote alongside your installation proposal.
