Looking for an HVAC Company in Belle Mead, Skillman and Montgomery Township? 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 Belle Mead, Skillman and Montgomery Township, 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 Belle Mead, Skillman and Montgomery Township.” 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 Belle Mead, Skillman and Montgomery Township, NJ

Jump to the table ↓

New Jersey licenses heating and cooling work to a named person. A Master HVACR Contractor license is held by an individual, registered with the Division of Consumer Affairs, and searchable by anyone in about a minute. State law requires the number and the HVACR Contractor designation to appear on a company’s website, invoices and advertising.

Four of the seven companies here publish it, and three publish nothing at all. This guide reports, for every company, exactly what it publishes about its own license and exactly what the state record returns.

How We Selected These Companies

This guide covers three municipalities: Montgomery Township (Belle Mead, Skillman, Blawenburg), Rocky Hill and Millstone Borough. Montgomery Township contains the postal villages of Belle Mead, Skillman and Blawenburg, which is why most addresses here carry one of those names rather than the township’s.

A company appears here if it holds a New Jersey registration to do the work — a Master HVACR license or a Home Improvement Contractor registration, verified at the Division of Consumer Affairs — and if it works for homeowners in these towns, either from premises inside them or by saying so on its own website.

Premises are not the test. Heating and cooling companies drive to the customer, so a shop inside the township is not required and a shop outside it is not excluded. What matters is whether they actually come here.

One note on the word Millstone, because it sends people forty miles in the wrong direction. Millstone Borough is a four-hundred-person village on the Millstone River in Somerset County, next to Montgomery. New Jersey also has a Millstone Township in Monmouth County. At least one heating company advertising “Millstone” serves the Monmouth one — its own town list runs Manalapan, Marlboro, Colts Neck and Jackson. Every company here was checked against which Millstone it meant.

Seven companies meet the test. They are listed alphabetically.

What This Market Looks Like

There is no heating and cooling company registered in Belle Mead or Rocky Hill at all. We checked the state’s home improvement register town by town: the businesses registered at Belle Mead and Rocky Hill addresses are carpenters, painters, landscapers, flooring and remodeling firms. Not one is an HVAC company.

Heating work in Montgomery Township is done by the plumbing-and-heating shops and by companies driving in from Princeton and Lambertville. Fifteen people holding an active New Jersey Master HVACR license live in these three towns — but a license held by a resident is not a company you can call, and most of them work for firms based elsewhere. The list below is companies, not license holders.

About This Guide

This guide is produced by Garden State Circle. Companies appear here because they meet the criterion described above. 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.

Garden State Circle is published in New Jersey by Tiffany and Jake Slowinski and covers Montgomery Township (Belle Mead, Skillman, Blawenburg), Rocky Hill and Millstone Borough. Contact the publisher at jake@gardenstatecircle.com. How every guide is made, in one place: how every guide is made.

A Note on Reading the License Column

New Jersey issues a Master HVACR Contractor license to a named person, not to a company. A number beginning 19HC belongs to that individual, and a company operates under the license of the person who qualifies it. State law requires the number and the HVACR Contractor designation to appear on a company’s website, invoices, contracts and advertising, so publishing it is a legal requirement rather than a courtesy.

A home improvement registration — a number beginning 13VH — is a different thing under a different regime. It registers a business to do home improvement work in New Jersey. It is not an HVAC credential and this guide never prints one in the HVACR column; where a company holds one, it appears in the last column, labelled as what it is.

The columns report state licensure on the date shown, and nothing else. They are not a rating, not a measure of quality, and not a statement about insurance. Not published means we read the company’s site and the number is not on it. It is a fact about a website on a date, and nothing more.

The Companies

Common Questions

Why are there only seven companies here?
Because seven is how many we could verify. There is no heating and cooling company registered at a Belle Mead or Rocky Hill address at all, and this guide does not carry a company over from a neighbouring town’s list unless that company says it works here. A company that appears on a Bridgewater or Somerville guide is not automatically on this one.

What is the difference between the two numbers in the table?
A 19HC is a Master HVACR Contractor license held by a named person — that is the heating and cooling credential. A 13VH is a home improvement registration held by a business, under a different regime. Both are real; only one of them is about HVAC work, and this guide keeps them in separate columns for that reason.

Three of these say “Not published.” Should that worry me?
It is worth asking about. State law requires the HVACR license number to appear in a company’s advertising, and three of the seven companies here do not put it anywhere on their site. Ask for it, and check it yourself against the state register — it takes about a minute. A company that gives you the number straight away has told you something useful.

A company advertises Millstone. Is that this Millstone?
Check the other towns in the same sentence. Millstone Borough here is next to Montgomery, on the river, with about four hundred residents. Millstone Township is in Monmouth County near Clarksburg. A company listing Millstone alongside Manalapan, Marlboro, Colts Neck or Jackson means the other one.

Who inspects heating and cooling work in these towns?
It depends which town. Montgomery Township runs its own construction department. Rocky Hill and Millstone do not have one — both are inspected by the State of New Jersey, with the regional inspector working out of the Rocky Hill Municipal Building. All three are listed below.

Who Governs Heating and Cooling Work in Montgomery Township, Rocky Hill and Millstone Borough, NJ

Two state agencies sit behind residential heating and cooling work in New Jersey. The Division of Consumer Affairs, through the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors, issues the Master HVACR license in this guide’s table. The Department of Community Affairs, Division of Codes and Standards administers the Uniform Construction Code, whose mechanical subcode governs the work itself. New Jersey adopted the 2024 editions of the model codes on August 17, 2026, according to the Division’s current codes table.

Permits and inspections are normally municipal. In two of these three towns they are not.

Municipality Construction permit office, as the town names it Phone Officials, as published Hours, as published
Montgomery Township (Belle Mead, Skillman, Blawenburg) Building & Construction Department, 100 Community Drive, Skillman 908-359-8211 Michael Krupsky, Construction Official Mon–Fri 8:00am–4:30pm; payments taken until 3:30pm
Rocky Hill Construction services provided by the State of New Jersey, Division of Codes and Standards, Office of Local Code Enforcement — Borough Hall, 15 Montgomery Avenue 609-924-7445 William D. Patterson, Acting Construction Official Tuesdays 1:00pm–3:00pm at Borough Hall
Millstone Borough Shared service with the State of New Jersey; the regional inspector is based at the Rocky Hill Municipal Building — Borough Hall, 1353 Main Street 908-281-6893 William Patterson, Building Inspector · Dan Devoti, Zoning Officer Tuesdays 1:00pm–3:00pm

Offices read September 4, 2026.

Rocky Hill and Millstone share the same state inspector and the same two-hour window a week. If you live in either borough, that is where a mechanical permit is issued, and the window is narrow — ring ahead rather than driving over. Montgomery Township publishes a construction official but does not name a mechanical subcode official on the pages we read, so this guide names none.

Fee schedules are adopted by ordinance and change. Requirements are interpreted by the town’s own construction office, or by the state office that serves it, not by us. We publish what each municipality published, with the date we checked it — confirm before you rely on it.

Something Out of Date?

Things change. A license is renewed under a different holder, a company moves, a phone number is retired, a business closes or opens a new office.

If anything on this page is wrong, tell us and we will fix it. Email admin@gardenstatecircle.com. Corrections are made whether or not a business participates in Garden State Circle, and there is no charge for one.

If your heating and cooling company is not on this page and you believe it should be, email the same address. The test is the one described at the top: a New Jersey registration to do the work, and either premises in Montgomery Township, Rocky Hill or Millstone or a published statement that you work here.

Something out of date?

This guide is maintained. If anything here is wrong or has changed — a license, a service area, or whether they still do that trade — tell us and we will check it. Businesses listed here are welcome to write in directly.
