Emergency HVAC Service 24/7

Call at two in the morning and a person picks up, not a message service that promises a callback. Emergency furnace repair when the heat quits in January, cooling when a July night will not break, and commercial calls that cannot wait for Monday.

What Is That Burning Smell?

Dust burning off a heat exchanger on the first cold night is normal and passes in an hour. Hot plastic, an electrical smell, or anything that arrives with a tripping breaker is not, and the right move is to shut the system down before you call. This explains how to tell them apart.

The two in the morning call

What Happens When You Call at 2am

The phone is answered by someone who can dispatch, and the first ninety seconds are triage rather than data entry. Is anyone unsafe. Is there a gas smell, a carbon monoxide alarm sounding, water running where it should not be. If the answer to any of those is yes, you get told to leave or to shut something off before we talk about scheduling anything.

Then the practical part. Make and fuel of the system, what it is doing and what it was doing before it stopped, whether the breaker has tripped, and what the thermostat reads against what the house reads. Half of no-heat calls are narrowed to a likely component on the phone, which decides what the on-call technician puts on the truck before setting off.

You are told which office is covering you — Carlstadt, Belleville or Englewood Cliffs — and given a realistic window based on where the truck is and what the roads are doing. If a repair genuinely cannot be finished until a supplier opens, we say so on the phone rather than at your door, and we work on getting temporary heat into the house instead.

Live answer overnight, at weekends and on holidays
Safety triage before scheduling — gas, CO, water and electrical first
After-hours rates stated before a truck is sent, never after the work
Stabilise first, finish properly second — heat back on beats a perfect repair at 4am

What Counts as an HVAC Emergency

Not everything that goes wrong at night needs a truck at night, and an honest contractor will tell you which is which. Here is how we sort them when you ring.

Situation	Do this first	When to call
Gas smell anywhere in the building	Get everyone out. No switches, no phones indoors. Call the utility from outside.	After the utility has made it safe. We handle the equipment side.
Carbon monoxide alarm sounding	Outside, doors open, emergency services. Do not restart anything.	Immediately after. The system stays off until it is combustion tested.
No heat, freezing outside	Check the breaker and the furnace switch, then open cabinet doors under sinks on outside walls.	Now. Pipe damage becomes the bigger bill within hours.
No cooling in a heat wave, vulnerable occupant	One cool room, blinds down, fluids. Check the outdoor breaker.	Now. Age and health conditions move this up the list.
Hot plastic or electrical smell	Shut the system off at the breaker and leave it off.	Now, and do not run it again in the meantime.
Water pouring from the air handler	Power off at the breaker, then catch the water and protect the ceiling below.	Now if it is running down a wall; morning if a pan is holding it.
Boiler down in a multifamily or tenanted building	Note the last fault code and whether the circulators are turning.	Now. Habitability obligations do not wait for business hours.
Rooftop unit down over a server room or a kitchen	Get portable cooling to the critical space if you have it.	Now. Tell us the unit make and roof access arrangements.
One room uncomfortable, rest of the house fine	Nothing overnight. Note when it happens and which registers are weak.	Business hours — this is a ductwork question.
New noise, system still running and heating	Record it on your phone if you can.	Business hours, but soon. Noises rarely get cheaper.

Members Are Dispatched First Commercial Service

Why call ICS

Built to Answer the Bad Night

Three dispatch offices, stocked trucks, and technicians who have worked these failures for decades. Emergency work is not a side line.

Someone Picks Up

Overnight, weekends, holidays. You reach a person who can dispatch and who can tell you what to do while you wait.

Three Offices

Carlstadt for Bergen, Hudson, Passaic and the city; Belleville for Essex, Union, Morris and the western counties; Englewood Cliffs for the GWB corridor.

Buildings Too

Rooftop units, commercial boilers, chillers and controls. Property managers get one number for a tenant complaint at any hour.

Priced Before Dispatch

After-hours rates differ from daytime rates. You hear ours on the phone, before a truck moves, and the diagnosis is quoted before any repair starts.

On site

Stabilise, Diagnose, Repair, Return

Make It Safe
Gas, combustion and electrical checked before anything is restarted. A system that failed unsafely stays off until it tests clean.
Get Heat or Cooling Back
The overnight goal is a working building. That may be a component swap from the truck or a controlled temporary fix.
Show You the Fault
The failed part, the reading that condemns it, and whether it is a symptom of something larger. No pressure decisions at 3am.
Finish in Daylight
Where a part must be ordered or the real repair needs light, we come back and complete it — and tell you what it will take before we leave.

No Heat, No Cooling, Right Now?

Do not wait until morning to find out whether it is urgent. Ring the line and we will tell you honestly.

Good questions

Emergency Service FAQs

Do you really answer the phone at night?

Yes. The emergency line is staffed overnight, at weekends and on public holidays, by someone who can dispatch rather than take a message. Whether a truck rolls at that hour depends on what is wrong, where you are and what is already running — but you get a straight answer on the call, not a callback promise. If your situation is genuinely safe to leave until morning, we will tell you that too.

How quickly can someone get here?

It depends on the hour, the weather and which office covers you. A Bergen or Hudson address at midnight is a short run from Carlstadt. Sussex or Warren at the same hour is a long drive on roads that may be the reason your heat quit. We give you a real window on the call and update it if it moves, rather than quoting a number on a web page that has no idea where you live.

What does emergency furnace repair cost after hours?

After-hours labour is charged at a different rate from daytime labour, and it varies with the hour and the day. You are told the diagnostic rate before a truck is dispatched, and the repair is quoted and approved before any work begins. Plan members pay a member rate on after-hours calls, which is one of the reasons the plan pays for itself in a bad winter.

My furnace stopped. What should I check before calling?

Four things, and they solve a surprising number of calls. The breaker for the furnace or air handler. The switch on the wall beside it, which looks like a light switch and gets flipped by accident. The thermostat — batteries, and set to heat rather than to fan. And the filter, if it is grey enough to block light. If none of those is it, stop there and call rather than resetting a locked-out system repeatedly.

Should I keep resetting the system to get through the night?

No. A lockout is a safety control doing its job, and repeated resets can turn a cheap sensor fault into a cracked heat exchanger or a flooded burner compartment. One reset to see if it holds is reasonable. After that, leave it and call. If the lockout came with a smell or a tripping breaker, do not reset at all.

Do you handle emergencies in commercial buildings?

Yes, and a large share of our overnight work is commercial. Rooftop units, split systems serving offices and retail, commercial boilers and steam, chillers, cooling towers and the controls that tie them together. Property managers and building engineers get one number for a tenant complaint at any hour. Tell us the unit make, the roof or mechanical room access, and who can let a technician in.

Will you have the part on the truck?

Often. Igniters, flame sensors, capacitors, contactors, pressure switches, thermocouples, common circulators and control boards for the makes we see most ride on the trucks. Rarer boards, sealed compressors, heat exchangers and anything for an unusual import may wait for a supplier to open. When that happens we say so on the phone if the symptoms allow, and work on temporary heat rather than leaving you with nothing.

Do plan members get seen first?

Yes, and on the worst nights that is the difference between tonight and tomorrow. Safety calls go ahead of everything regardless of who is calling — a gas smell or a CO alarm is never triaged behind a membership. After that, plan holders sit ahead of unscheduled callers, and their equipment history is already on file, which usually makes the visit shorter as well.
