Commercial HVAC
Offices, warehouses, retail and multi-tenant buildings. Planned maintenance, phased equipment replacement, in-house sheet metal and remote monitoring — held by one contractor who schedules around your tenants instead of around our own week.
Built for Buildings That Stay Open
Occupied floors, live tenants, a loading dock with a schedule. We plan the work to fit them.
Commercial HVAC Across Northern NJ and NYC
A Class B office off Route 3 with a dozen rooftop units of three different vintages, half of them past the age where parts arrive next day. A Meadowlands distribution building where the only real comfort load is the front office block and the rest is make-up air and unit heaters. A pre-war Manhattan property on two-pipe changeover, where somebody on eleven files a ticket every October and somebody on four files one every April. Different buildings, same problem: the mechanical system is nobody’s job until it is everybody’s emergency.
ICS has worked on that end of the market since 1990. The people who call us are facility managers, property managers and general contractors, not homeowners, and what they need is different. Predictable scheduling. A technician who can be badged in and knows where the roof hatch key lives. Paperwork that clears building management before the truck arrives. A scope that does not stop at the equipment and hand the ductwork to somebody else.
We hold the whole mechanical scope. Service and planned maintenance, equipment replacement staged so the building keeps trading, ductwork we cut and form in our own shop, controls, and monitoring that watches the equipment between visits. One contract, one point of contact, nobody to point at when something is not right.
- Planned maintenance agreements and demand service on all makes
- Night, weekend and holiday work scheduled as normal, not as an exception
- Certificates of insurance and licence documentation issued before mobilisation
- In-house fabrication, so a duct change does not queue behind another shop’s work
Buildings We Work In
What We Take On
Six lanes of work, each with its own page. Most buildings need two or three of them, and it is usually simpler when the same contractor holds all of them.
Service & Maintenance
Scheduled visits on an asset list you can audit, plus demand calls when a tenant floor goes warm. Belts, bearings, controls, refrigerant circuits and the log that shows what changed.
Installation & Replacement
Changeouts sequenced so the building keeps working. Rigging, curb adaptation, temporary conditioning where a floor cannot go without, and commissioning that is written down.
Sheet Metal Fabrication
Our own shop cuts, forms and seals rectangular and round duct, fittings, plenums and transitions to the pressure class the drawings call for. Shop drawings, then metal.
Remote Monitoring
Sensors on the equipment and eyes on the trend. A compressor drawing more amps each week is a scheduled repair; the same compressor in August is a lost floor.
Rooftops, Chillers & Towers
Packaged rooftop units, air- and water-cooled chillers, cooling towers and the pumps and controls between them. Repair, overhaul or changeout on a capital plan.
Boilers, Steam & Controls
Commercial boilers, steam distribution and trap surveys, plus building automation work — new front ends, sequence corrections and getting the graphics to match the plant.
Uptime Is the Deliverable
Nobody thanks a mechanical contractor for a good week. The job is to make the bad weeks rare and short.
Metal In-House
Transitions, offsets and fittings come off our own brake and roll former. A field change becomes a shop ticket, not a two-week wait behind somebody else’s job.
Off-Hours Is Normal
Overnight, weekend and holiday windows are how commercial work gets done. We price and staff for them rather than treating them as a favour.
Paperwork That Clears
Certificates of insurance naming the entities you need named, licence records, and job documentation your ownership group can file without chasing us.
One Contractor
Mechanical, duct, controls and monitoring under one agreement. When the complaint is vague, nobody gets to say it is the other trade’s scope.
From Walk-Through to Coverage
Walk the Building
Roof, mechanical rooms, closets. We build an asset list from nameplates, note what the access actually is, and find out which units nobody has opened in years.
Separate Urgent From Capital
What has to be fixed this quarter, what belongs in next year’s budget, and what can be maintained for a few more seasons without gambling on it.
Work Around Occupancy
Windows agreed with building management, protected paths through tenant space, and a scope broken into pieces that each end with the building running.
Document and Watch
Readings on record, as-builts where we changed something, and monitoring on the equipment that would hurt most if it stopped quietly.
Managing a Building? Let’s Walk It.
A site survey costs you an hour and gives you an asset list, a condition read and a straight answer on what is worth maintaining.
Commercial HVAC FAQs
What size buildings do you take on?
From a single-tenant retail box on one rooftop unit up to multi-storey office and industrial properties running chillers, towers and a plant room. The practical limit is not tonnage, it is whether we can staff the building properly. If a property is bigger than we should take on, we will say so at the survey rather than after the contract.
Can you work nights and weekends so tenants are not disrupted?
Yes, and for most occupied buildings that is the default rather than the exception. Roof work, riser work and anything noisy or dusty inside tenant space gets scheduled into an agreed window. Tell us the building’s rules on freight elevator hours, hot work and dock access and we will build the sequence around them.
Do you provide certificates of insurance and licence documentation?
Yes. Send us the certificate holder and additional insured wording your ownership or management company requires and we will have it issued before mobilisation. We are licensed and insured in New Jersey and carry the documentation building management and general contractors normally ask for at prequalification.
Will you service equipment another contractor installed?
Yes. Most of the commercial equipment we maintain was put in by somebody else. We start by documenting what is actually there, because nameplate data and the building’s records disagree more often than not, then quote maintenance on what we found. Inheriting a neglected asset list is normal work, not a reason to decline.
Do you cover New York City as well as New Jersey?
Yes. Our Carlstadt shop is a short run to the Lincoln and Holland tunnels and the George Washington Bridge, and we work commercial properties in the five boroughs alongside the Northern New Jersey footprint. See the New York City page for how the city work is dispatched and staged.
Do you fabricate your own ductwork or subcontract it?
Our own. The shop cuts, forms and seals rectangular and round duct, fittings and plenums for our projects, which matters most when a field condition changes and the drawing no longer fits the building. Details of gauges, seams and pressure classes are on the fabrication page.
Can you work as a subcontractor to a general contractor?
Regularly. Fit-outs, tenant improvements and building repositioning projects come to us through general contractors, and we work to their schedule, their submittal process and their coordination meetings. Duct, equipment and controls under one subcontract usually removes a fight over who owns the air balance at the end.
What happens when something fails outside business hours?
Emergency coverage runs around the clock, and a maintenance agreement means the technician who takes the call already has the asset list. Where the building is on remote monitoring, we often know before the phone rings. See emergency service for how out-of-hours calls are handled.
Where Our Commercial Crews Work
Dispatched from Carlstadt, Belleville and Englewood Cliffs across nine New Jersey counties and the five boroughs.
Tell Us About the Building
Send the address, roughly what is on the roof or in the plant room, and what has been going wrong. We will come and look.
Leaky ductwork can waste conditioned air before it ever reaches your rooms. Proper duct sealing helps improve airflow, reduce energy loss, and create more consistent temperatures throughout your home.

Indoor humidity affects more than comfort. Too much moisture can make your home feel sticky, while air that is too dry may cause irritation and discomfort.
Proper HVAC operation and humidity control can help create a healthier, more comfortable indoor environment throughout the year.

Your HVAC system often gives warning signs before a bigger problem develops. Test your thermostat, listen for unusual sounds, watch for moisture near drain lines, and keep the outdoor unit clear.
A quick response can help protect your comfort, prevent avoidable damage, and support reliable system performance all season long.
