Heating and Cooling Contractors in the Watchung Hills: A Guide for Warren, Watchung and Green Brook

Heating and Cooling Contractors in the Watchung Hills: A Guide for Warren, Watchung and Green Brook
Published | Updated

Looking for an HVAC Company in the Watchung Hills? Start Here

There are few things that make you care about HVAC companies faster than an air conditioner quitting during a New Jersey heat wave. Same goes for waking up in January and realizing the house feels suspiciously like the garage.

If I were searching for an HVAC company in the Watchung Hills, I would not start by asking who has the biggest company or the most polished website. I’d start with: Who actually services my town, works on the system I have and will come out for the problem I need fixed?

Because “HVAC” covers a lot. Air conditioning repair. Furnaces. Boilers. Heat pumps. Mini-splits. Ductwork. Full system replacements. Maintenance. A company can technically be an HVAC contractor without being equally focused on every one of those things.

The next question I’d ask is whether they actually repair systems or primarily want to replace them. If my AC stops cooling, I want someone willing to diagnose the problem before I start mentally spending $15,000. Sometimes the answer really is a new system. Sometimes it isn’t.

I also care about smaller service calls. Homeowners search for things like “AC repair near me,” “someone to fix my furnace” or “HVAC company that works on mini-splits.” That is very different from shopping for an entirely new heating and cooling system, and a company’s website does not always make the distinction terribly clear.

Then there is emergency service. If your heat goes out overnight or your AC dies on the hottest Saturday in July, knowing who advertises 24-hour or emergency service matters. We use what the companies themselves publish rather than assuming availability.

And yes, I care whether they are actually local. Some HVAC companies in these guides have offices right in the towns they serve. Others are based farther away and regularly work here. HVAC is a service business. The more useful question is usually not “What town is their office in?” It is “Do they regularly come to my town and handle my type of system?”

I also want to know who is legally behind the work. In New Jersey, heating and cooling companies operate under a Master HVACR contractor’s license held by an individual. The license itself is not a review or a quality rating. It is simply one of the few pieces of information about an HVAC company that can be independently checked.

So we checked it. The guide below shows what each company publishes about its HVAC license and, where we could check it, the person attached to that license in the state record. When a company does not publish the information or we could not confirm it, we say that too.

This is not our ranking of the “best HVAC companies in the Watchung Hills.” Frankly, that would not be very useful. Someone with a 25-year-old boiler has a different problem than someone looking for a heat pump, a new central air system or somebody willing to fix an AC unit that picked the absolute worst weekend of the year to stop working.

Use the guide below the way I would. Figure out who serves your town. Look at what they actually specialize in. Check the licensing information. Look at emergency availability if that matters. Then call the companies that make sense for your specific problem. Less guessing. More actual information.

The Guide: Heating and Cooling Contractors in Warren, Watchung and Green Brook, NJ

Jump to the table ↓

New Jersey licenses heating and cooling work to a named person. Every company that installs or repairs a furnace, boiler, heat pump or air conditioner in this state works under a Master HVACR contractor’s license held by an individual, registered with the State Board of Examiners, and searchable by anyone in about ninety seconds.

Almost nobody publishes which one. Search for a contractor in Warren or Watchung and you will find companies described as “fully licensed and insured” — a phrase that costs nothing to write and carries no information at all. This guide reports, for every company, exactly what it publishes about its own license and exactly what the state record says. Where a company publishes nothing, the guide says that too.

How We Selected These Companies

This guide covers three municipalities: Warren, Watchung and Green Brook.

A company appears here if it installs, repairs or replaces residential heating and cooling systems for homeowners in those towns, and if it says so itself — by naming one of the three on its own website, or by holding a state contractor registration at an address inside one of them.

One note on the word Warren, because it costs people money. Warren Township is in Somerset County, next to Watchung and Green Brook. New Jersey also has a Warren County, an hour west, and several heating and cooling companies use the bare word to mean the county — Phillipsburg, Hackettstown, Washington. A company that says it serves “Warren” is not necessarily saying it serves this one. Every company on this page was checked against which Warren it meant, and at least one otherwise well-qualified company came off for that reason.

The license is not the criterion. It is the first column. Making it a condition of entry would have quietly deleted local businesses on the strength of what their websites do not say. Instead every qualifying company is listed, and the column reports what each one publishes and what the state registry returns.

Eight companies meet the test. They are listed alphabetically. Some are registered in these towns and some are half an hour off, and the table says which is which.

About This Guide

This guide is produced by Garden State Circle. Companies appear here because they meet the criterion described above — they perform residential heating and cooling work for homeowners in the towns this guide covers. That is a test, not a judgment, and it is the only route onto this page. No company can pay to be included in this guide, to be listed higher, or to change what the comparison table says about it. Companies are listed alphabetically, and every detail in the table was verified against each company’s own website and against the New Jersey Division of Consumer Affairs licensee record in September 2026.

Everything under the heading that begins this guide is governed by the rules above, on every guide we publish. Where a sponsor’s message appears above that heading, it is paid for and labelled, and it buys nothing in the guide. Garden State Circle is supported by the businesses that participate in it. Participation pays for our ongoing work: keeping a business’s entry accurate, re-checking its record, and publishing a page of its own details that the business maintains. There is no paid placement in this guide. Participation does not buy a place here, a position here, or anything the comparison table says.

Which of These Companies Is Actually in These Towns

Most homeowners asking whether a company is “local” are really asking one question: will they come out for my small job? That is worth separating from geography, because the two are not the same thing.

On the question of geography, the answer is short. Two of the eight companies here hold a New Jersey contractor registration at an address inside the three towns:

  • EMS Electric Mechanical and Plumbing — Warren
  • Lou Fasano Heating & Cooling — Green Brook

Neither publishes a street address on a working website of its own, so this guide gives the town and nothing more. That is a fact about what they publish, not about whether they are there: both registrations are current and both are recorded in Green Brook and Warren respectively by the state.

The other six work from Old Bridge, Edison, Woodbridge, Manville and Milford and travel here, which for this trade is ordinary rather than a defect. Every one of the six names Warren, Watchung or Green Brook on its own website.

On the second question — whether a company will take a single repair call rather than only quoting replacements — we are asking every company on this list directly, and their answers will be published here as they come in. It is not a question a website answers honestly, which is exactly why it is worth asking.

The Companies, Compared

Listed alphabetically. The middle two columns are two different things and the difference is the point: one reports what the company puts on its own website, the other reports the name the State Board of Examiners holds the license under.

License numbers and holders were verified against the New Jersey Division of Consumer Affairs licensee record and each company’s own website in September 2026.

A Note on Reading the License Column

Five of the eight companies here publish a full-format Master HVACR license number that resolves correctly the moment you type it into the state’s own search. That is a better ratio than any market this guide’s publisher has surveyed so far, and it is worth saying plainly: Arctic Air, Sam’s Air Control, Temp Control, Valairco and Warren Heating and Cooling all publish a number you can check yourself in under two minutes.

One publishes it in a shortened form. Edison Heating & Cooling prints NJ HVAC/R license #4687. Typed as printed it returns nothing. Expanded to the full twelve-character format it reads 19HC00468700 and is held by Michael E Iarrapino, which is what appears in the table above. The license is real, current, and effectively unverifiable by a homeowner reading the website.

One publishes a number from a different regime, with a typing error in it. EMS Electric Mechanical and Plumbing prints HI License 13VHO3784100. A number beginning 13VH is a New Jersey Home Improvement Contractor registration, not a Master HVACR license, and the character after 13VH on their page is the letter O rather than a digit. We have asked them for their HVACR number and will publish it when they answer.

One publishes nothing at all, and has no working website. Lou Fasano Heating & Cooling holds a current New Jersey Home Improvement Contractor registration recorded in Green Brook and has run a branded fleet out of that township for years. The absence of a website is a fact about the company’s marketing, not about its standing, and this guide would rather list a company that cannot be found online than pretend the trade is only made up of the companies that are good at being found.

What this guide could not tell you. No company on this page publishes the name of the individual who holds its Master HVACR license alongside the number. In every case above, the holder’s name came from the state register rather than from the company. That is the most complete form of the disclosure and the one this guide would like to be able to report for somebody.

The Companies

Arctic Air Conditioning, Old Bridge

Arctic works from Pleasant Valley Road in Old Bridge and publishes a service-area list that names Warren, Watchung and Green Brook individually, along with four New Jersey license numbers — heating and cooling, plumbing, home improvement and electrical — which is more than any other company in this guide puts on a single page.

Edison Heating & Cooling, Edison

Edison Heating & Cooling maintains separate service pages for Warren, Watchung and Green Brook Township, and is one of only three companies here that names all three towns; its Master HVACR license is held by Michael E Iarrapino and is published on the site in shortened form.

EMS Electric Mechanical and Plumbing, Warren

Registered in Warren and describing itself as a full-service mechanical, electrical and plumbing group, EMS publishes a services list covering new HVAC installations, split systems, rooftop units, custom fabricated duct work and ductless air conditioning, along with its electrical business, master plumber and boiler licenses.

Lou Fasano Heating & Cooling, Green Brook

Lou Fasano Heating & Cooling holds a current New Jersey Home Improvement Contractor registration recorded in Green Brook Township, describes itself as an air conditioning and heating company, and runs a branded van fleet; it has no working website, which is why the license column above is as short as it is.

Sam’s Air Control, Edison

Sam’s works from Route 1 in Edison, names Warren and Watchung among the towns it serves, and publishes its Master HVACR license in full format alongside a home improvement registration — the license is held by Igor Traspov.

Temp Control Heating & Air Conditioning, Woodbridge

Temp Control operates from Main Street in Woodbridge, publishes a Somerset County service list that names Warren, Watchung and Green Brook, and prints its Master HVACR number in the full format the state search will accept.

Valairco, Manville

Based on Kennedy Boulevard in Manville since 1946, Valairco names Warren on its service-area page and publishes both its HVACR contractors license and its home improvement license, the first held by Kevin J McHugh.

Warren Heating and Cooling, LLC, Milford

Despite the name, Warren Heating and Cooling works from Rick Road in Milford in Hunterdon County; it names both Warren and Watchung among the towns it serves and has published its Master HVACR license number in full format for years.

Common Questions

How do I check whether a New Jersey HVAC contractor is licensed?

Go to the New Jersey Division of Consumer Affairs license verification system at newjersey.mylicense.com, choose Person Search, set the profession to HVACR and the license type to Master HVACR Contractor, and search by the license number or the holder’s surname. The result gives you the holder’s name, the license number and whether the status is active. It is free and it takes about ninety seconds.

What is a Master HVACR contractor’s license?

It is the New Jersey license that permits heating, ventilation, air conditioning and refrigeration work. It is issued to an individual, not to a company, after an examination, and it carries a $3,000 bond and a continuing education requirement at each renewal. A company performs HVAC work under the license of a named individual associated with it.

Does the license number have to be on the company’s website?

New Jersey requires a licensed Master HVACR contractor to display the license number and the designation on business vehicles, websites, invoices, stationery, contracts and advertising. Five of the eight companies in this guide do, which is what the middle column of the table above is reporting.

Is a 13VH number the same thing?

No. A number beginning 13VH is a New Jersey Home Improvement Contractor registration. It is a real credential and worth having, but it is a different regime from the HVACR license and it does not tell you who holds the heating and cooling license behind the work. Two companies in this guide publish a 13VH and no HVACR number.

Does it matter that a company is based outside these towns?

Not on its own. Heating and cooling work travels to the customer, so where a company keeps its office says less than most homeowners assume. It is worth checking which Warren a company means — Warren Township here, or Warren County an hour west — and worth asking whether they will take your particular job and how quickly they answer in January.

Who Governs Heating and Cooling Work in the Watchung Hills, NJ

Heating and cooling work in New Jersey answers to two state agencies with confusingly similar names, and they do different things. The license belongs to the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors, part of the Division of Consumer Affairs — (973) 504-6250 — which issues the Master HVACR license in the table above and runs the search described in the questions above. The permit belongs to the Uniform Construction Code, N.J.A.C. 5:23, written by the Department of Community Affairs, Division of Codes and Standards — (609) 292-7899 — and enforced by each municipality’s own construction office, listed below. New Jersey adopted the 2024 editions of its construction subcodes on August 17, 2026; the mechanical subcode is the International Mechanical Code 2024 (N.J.A.C. 5:23-3.20) and the fuel gas subcode is the International Fuel Gas Code 2024 (N.J.A.C. 5:23-3.22), per the Division’s current-codes table, read September 2, 2026.

Municipality Construction permit office, as the town names it Phone Construction Official, as published Hours, as published
Warren Construction Code Not published on the department page Not published Not published on the department page
Watchung Building / Construction Department (908) 756-6093 ext. 219 Dan Niro Monday–Thursday 8:00am–4:00pm; Friday 8:00am–1:00pm
Green Brook Construction Department 732-968-1023 ext. 6606 Frank LaGuarina Monday–Friday 8:30am–4:00pm

Every office above was opened and read on September 4, 2026. Names are published only where the municipality publishes them.

Three municipalities, three offices, and they do not run alike. Watchung and Green Brook both publish the person — Dan Niro is Watchung’s Construction Official and also its plumbing inspector, and Frank LaGuarina is Green Brook’s Construction Official and also its building subcode official, which is normal in small municipalities and is why an inspector may be in only one place on a given day. Warren Township describes its Construction Code office by function on its own site and names nobody, so this guide names nobody either. The inspection windows are the practical difference: Watchung’s building and fire inspections run midday, Tuesday to Thursday, while Green Brook’s electrical inspections run from 6:00am to 8:00am on Tuesdays and Thursdays and its plumbing inspections from 5:00pm to 7:00pm on Mondays and Thursdays — hours worth knowing before a contractor tells you when they can be there.

Fee schedules are adopted by ordinance and change. Whether a particular job needs a permit is interpreted by the town’s own construction office, not by us. We publish what each municipality published, with the date we checked it — confirm with the office before you rely on it, and if any of it has changed, the correction address at the foot of this page is the fastest way to tell us.

Something Out of Date?

This guide is maintained. If anything here is wrong or has changed — a name, an address, a license number, or whether a business has closed — tell us and we will check it. Businesses listed here are welcome to write in directly, and a company that publishes a license number we have recorded as absent is exactly the kind of correction we want.

And if you run a heating and cooling company that should be on this list and is not, write to us. We would rather be told than be incomplete. The test is the same one every company here cleared: that you install, repair or replace residential heating and cooling systems for homeowners in Warren, Watchung or Green Brook. A permit pulled in one of those townships, a completed job, or your license will do it. Show us that and you go on the page.
