HVAC Repair, Replacement & Maintenance

ICS has been working on buildings in this corner of the state since 1990 β€” mill-era two-families in Passaic County, post-war splits in Bergen, brownstones in Hudson County, and office and retail space across the river. More than 12,000 installations later, the lesson repeats itself: the box in the basement is rarely the whole story.

Most of the calls we take are not equipment faults. A back bedroom that never gets cold, a system that runs and runs without satisfying the thermostat, a compressor that has failed twice in five years β€” those trace back to airflow, refrigerant charge, or a duct system that was never designed for the equipment eventually bolted to it. Swapping the box without finding that buys you a quieter version of the same complaint.

So we test first and quote second, whichever lane you land in. Every service page below tells you what that lane covers and what actually decides the price β€” because the honest answer to most pricing questions is a list of variables, not a number.

  • Residential and commercial work from the same three offices
  • All major brands serviced, whoever put the system in
  • Custom sheet metal fabricated for the job, not forced to fit
  • Rebate paperwork and financing handled with the install

Which Lane Do You Need?

It has stopped, and it is cold or hot in hereThat is an emergency call. Phone the line rather than the form.
It runs, but something is wrongNoise, weak output, short cycling, a room that never comes right.
It is old and you are decidingReplacement, and the moment to fix whatever the ducts are doing.
It works and you want it to stay that waySeasonal maintenance, or a plan that books the visits for you.
The full list

What ICS Works On

Nine lanes, each with its own page. Pick the one that matches what is happening in the building and you will land on the detail rather than another overview.

Heating & Furnaces

Gas and electric furnaces, steam and hot water boilers. Repair, replacement sized on a load calculation, and autumn tune-ups.

Air Conditioning

Central air and condenser work: charge, capacity on a design day, and the reason the upstairs is still warm at six in the evening.

Heat Pumps

Cold-climate systems that keep useful output well below freezing, plus the dual-fuel setups that suit a house with a sound gas furnace.

Ductless Mini-Splits

Wall units, ceiling cassettes and floor consoles for additions, attic conversions and rooms the ductwork was never run to.

Indoor Air Quality

Whole-house dehumidification, humidifiers, filtration that the blower can actually pull through, and energy recovery ventilation.

Ductwork & Zoning

Duct cleaning, sealing and repair, static pressure testing, and zoning for the floor that has always been the odd one out.

Maintenance Plans

Two scheduled visits a year, readings kept on file so this spring can be compared with last spring, and priority when the phones are busy.

Emergency Service

No heat in January, no cooling in a heatwave, water where it should not be, a burning smell. The line is staffed around the clock.

Commercial HVAC

Rooftop units, chillers and cooling towers, steam plant, building automation, sheet metal fabrication and remote monitoring.

Why ICS

One Contractor, Start to Finish

Comfort up, running cost down. Everything below exists to serve those two numbers.

Home and Building

The same company that services your furnace runs the rooftop units on your office. Residential and commercial share a dispatch desk, so nothing gets handed to a stranger.

Metal Made to Fit

Transitions, plenums and fittings fabricated for the space instead of a stock part shimmed into place. Bad duct geometry ruins good equipment.

Certified Where It Counts

NATE-certified technicians, Mitsubishi Electric Diamond contractor status, and cold-climate heat pump certification on the electrification work.

Paperwork Included

Permits pulled, inspections met, and utility and state incentive applications filed as part of the job rather than left with you.

How a job runs

From First Call to Sign-Off

  1. Describe the Symptom

    Tell the dispatcher what the system is doing and roughly how old it is. That decides whether you need a technician today or a survey next week.

  2. Nearest Office Dispatches

    Carlstadt covers Bergen, Hudson, Passaic and the city. Belleville covers Essex, Union, Morris and the long runs out to Sussex and Warren. Englewood Cliffs takes the GWB corridor.

  3. Findings Before Options

    You get the readings β€” pressures, temperatures, combustion, airflow β€” and then the choices they justify. Nothing is ordered before you say yes.

  4. Install, Commission, Record

    Permits pulled where the work needs them, the system balanced and re-tested at handover, and the numbers filed for the next visit.

Not Sure Which Service You Need?

Describe what the system is doing and we will point you at the right lane β€” or send a technician if it cannot wait.

Before you call

Questions About Working With Us

What does an HVAC repair visit cost?

A diagnostic visit is quoted when you book, so there is no surprise at the door. What moves the repair itself is the part, how buried the component is, and whether the fault is one thing or a symptom of something upstream. You approve the repair after the diagnosis, and if the sensible answer is replacement, we say so and put the diagnostic toward it.

Do you work on equipment you did not install?

Yes, and most of our service work is exactly that. Our technicians are NATE-certified, which is a manufacturer-independent qualification, and we carry parts for the brands common in this region. The one thing worth telling us up front is who installed it and when, because a system still inside its parts coverage is handled differently.

How quickly can someone get out to me?

No-heat, no-cool and anything involving a smell, a leak or a shutdown is triaged ahead of routine work, day or night. Beyond that, honesty is better than a promise: on the third freezing night of a cold snap every contractor in the county is behind. Plan holders are scheduled first, which is most of what a plan buys you in January.

Do you handle commercial buildings as well as houses?

Both, from the same shop. The commercial side runs rooftop units, chillers and cooling towers, steam plant, building automation and sheet metal fabrication, with scheduled service contracts and remote monitoring for sites where a failure is a business problem rather than an uncomfortable evening.

Which towns and counties do you cover?

Bergen, Essex, Hudson, Passaic, Union, Morris, Sussex and Warren counties, plus the five boroughs of New York City. Sussex and Warren are the longest drives in the footprint, so we treat them as scheduled service and planned replacement work. The service area map lists every town with its own page.

Is financing available on a replacement?

Yes. Equipment rarely fails at a convenient moment, and a household forced to decide in one afternoon usually decides badly. Financing exists so the choice is made on what the building needs, and it stacks with the state and utility incentive programs we file for you.

Should one company do both my heating and my cooling?

In a ducted house they are one machine that happens to run in two directions, sharing a blower, a filter and every foot of duct. Split the responsibility and each contractor blames the other half. One company holding the airflow numbers year-round is how a summer complaint gets fixed with a winter reading.

How do I check an HVAC contractor is licensed in NJ?

Ask for two things: the New Jersey Master HVACR licence, which covers the mechanical work, and the Home Improvement Contractor registration, which covers the rest of the job. Both are searchable in the state register by number. ICS carries both, with insurance, and prints them on every estimate β€” a contractor who hesitates over that question has answered it.

Seasonal temperature swings can make keeping your home comfortable a little tricky. Instead of constantly adjusting the thermostat, consider using a programmable schedule that accounts for cooler mornings and evenings and warmer afternoons.

πŸ”₯πŸ‚ Have you turned your heat on yetβ€”even just for a test?

As Northern New Jersey transitions into cooler fall weather, now is a smart time to make sure your heating system is ready.

Turn your heat on briefly and pay attention. Does warm air reach every room? Do you hear unusual noises? Is there a persistent strange smell? Does the system struggle to reach the thermostat setting?

Finding a problem now gives you time to address it before a chilly night turns your heating system into an emergency.

Need your furnace or heating system checked? Contact Integrate Comfort Systems to get your home ready for the colder weather ahead.

The seasons are changing. Fall is on the way. You know what that means?

Winter is Coming. βš”πŸΊπŸ˜°

As we move into October, maintenance and consultations are two of the most important things you can do. First, maintenance to ensure your existing system is ready for the demands of the cold. Second, consultations to get more information on any new systems.
