Who Is Allowed to Work on Your Heating System in Onondaga County

New York does not issue a statewide HVAC license, so there is no state number to look up. Inside the City of Syracuse there is a municipal mechanical license with graded classes and a contractor list the city publishes, which makes a city address the one place in this county where you can check somebody without asking them anything. Outside the city line, what remains is the federal refrigerant certification, insurance, and whatever your own town or village requires.

There is no New York State HVAC license, so stop looking for the number

Start here, because it saves an afternoon. New York Business Express is the state's own portal for telling a business what it needs in order to operate, and its entry for a Heating, Ventilation and Air Conditioning Contractor lists only federal requirements under Section 608 of the Clean Air Act: the exam, the four types of certification, and the rule that only holders may purchase refrigerant in bulk containers or pre-charged parts. It lists no New York State license for the trade at all. The Department of State's Division of Building Standards and Codes says the other half of it in its published frequently asked questions: issues regarding local laws, zoning and the licensing of contractors or electricians are not handled by that Division, and in general every city, town, village and county is charged with administering and enforcing the Uniform Code within its own jurisdiction. Put together, that means a contractor who cannot give you a New York HVAC license number is not hiding anything, because the state does not issue one. The question that does have an answer is a local one, and in this county the answer changes at the city line.

Inside the city, a mechanical license, and the class sets the size of the equipment

The City of Syracuse operates a Board of Mechanical Examiners that issues mechanical licenses, and the application published by the Division of Code Enforcement defines what each class permits. A Class A Master HVAC Mechanical License entitles the holder to engage in the business of, and to secure permits for, the installation, alteration, maintenance and repair of any heating, ventilating or air conditioning systems and equipment. A Class B Limited HVAC Mechanical License covers the same work in new or existing residential structures including one and two family and multiple dwellings, plus medium sized commercial buildings, with ceilings of 30 ton air conditioning units, boilers up to 2,000 MBH input and furnaces up to 500 MBH input. A Class C Residential HVAC Mechanical License covers structures used only as the home of not more than two families and small commercial buildings up to 2,500 square feet, with air conditioning up to 5 tons, furnaces up to 200 MBH input and boilers up to 399 MBH input. Separate classes cover refrigeration, fire suppression, flammable and combustible liquid piping, and commercial kitchen hood exhaust. The published copy we worked from is headed 2023, so confirm anything time sensitive with the Division rather than with this page.

What that city license takes to get, which is why it means something

A credential is only worth asking about if it is hard to hold, and this one is. The Board requires a minimum of ten years of experience for a Class A Master Mechanical License, of which five years must have been working directly on the installation and maintenance of the equipment and systems for the class applied for, and three of those five on new construction of commercial or industrial installations. Class B and Class C require a minimum of five years related to the heating, ventilating and air conditioning industry, at least three of them working directly on installation and maintenance. One year is defined as 2,000 hours, and it has to be evidenced: W2 forms, educational certificates, letters from previous employers, or 1040 forms for the self employed, reviewed at a personal qualification review session. The license is then granted on attaining a minimum score of 70 percent in a written examination, held at the Division of Code Enforcement at 300 South State Street, 7th Floor. The licensing department telephone number on the application is (315) 448-8773. That is documented hours, a board review and an exam with a pass mark, which is a different thing from a sticker on a van.

The city publishes a contractor list, and a missing name is a telephone call, not a verdict

This is the unusually concrete part, and it is the reason a city address is the easiest one in the county to check. City of Syracuse Code Enforcement publishes a document headed List of HVAC Contractors, which sets out each firm's name, address, telephone number and owner name grouped under license headings including Master HVAC Mech, Limited HVAC Mech and Special HVAC, alongside the refrigeration and piping classes. You can look a company up without asking the company for anything, which in a trade where most credentials cannot be checked at all is worth having. Two cautions, both of which matter. The copy published at the address we recorded is dated 3/28/22 on every page, so it is not a live register, and a firm that appears on it has not necessarily kept the license current. More importantly, a name that is absent proves nothing on its own: firms change names, ownership and license class, and the honest next step for a missing name is the licensing department telephone number rather than a conclusion.

Outside the city, the one credential that is identical in every town

The towns and villages around the city do not run mechanical licensing boards, so the durable thing to ask about there is federal and it attaches to the individual rather than to the company. 40 CFR 82.161(a)(1) provides that any person who could be reasonably expected to violate the integrity of the refrigerant circuit during the maintenance, service, repair or disposal of appliances containing a class I or class II refrigerant, or a non-exempt substitute, must pass a certification exam offered by an approved technician certification program. There are four types: Type I for small appliances, Type II for medium, high and very high pressure appliances, Type III for low pressure, and Universal for all of them. Apprentices are exempt only while closely and continually supervised by someone who holds it. That distinction is not academic in a house. 40 CFR 82.152 defines a high pressure appliance by saturation pressure and gives R-410A among its examples, while a small appliance is one factory sealed with five pounds or less of refrigerant, such as a window unit. So the type that covers the window unit in your spare room is not the type that covers the equipment in your yard, and asking which one somebody holds is a real question rather than a polite one.

One thing you can see from the window during a refrigerant job

There is a check on this work that needs no paperwork at all, which is useful when the paperwork does not exist. 40 CFR 82.154(a)(1) provides that no person maintaining, servicing, repairing or disposing of an appliance may knowingly vent or otherwise release refrigerant into the environment, with a narrow list of exempt substances such as carbon dioxide, nitrogen and water. Paragraph (b) then requires anyone doing that work to use recovery or recycling equipment approved for that refrigerant and appliance type under 40 CFR 82.158. In plain terms: when a sealed component is being replaced or a system taken out, the refrigerant has to come out into a machine rather than into your yard, and that machine is a visible object sitting on the ground with hoses running to the unit. Its absence is one of the few signs a homeowner can read without knowing anything about the trade. It is also the reason a job that looks suspiciously quick sometimes was.

Whether the work needs a permit is decided by your municipality, not by Albany

This is why neighbors two streets apart get different answers and both of them are right. 19 NYCRR 1203.3(a)(1) requires every authority having jurisdiction to include in its code enforcement program provisions requiring building permits for work that must conform with the Uniform Code and the Energy Code. It then allows that municipality, where expressly set forth in its own local program, to exempt listed categories of work. Three of those categories touch this trade: installation of listed portable heating, ventilation or cooling equipment; replacement of any equipment provided the replacement does not alter the equipment's listing or render it inconsistent with the original specifications; and repairs that do not affect the structural system, the required means of egress or the fire protection system. Two things follow that people get wrong. The equipment replacement exemption is optional, so each municipality decides for itself whether to adopt it. And it is narrower than it sounds, because swapping an older atmospheric furnace for a high efficiency condensing one alters the listing and falls outside it. The regulation also says plainly that an exemption from needing a permit is not authorization to do work that violates the Codes.

In the City of Syracuse, HVAC is a separate trade permit even when a permit already exists

If your heating or cooling work sits inside a larger project, there is a trap in the city worth knowing about. The Central Permit Office lists its residential construction permit categories, and they run from additions and change of occupancy through decks, driveways, fenestration, interior remodels, new builds, pools, roofs, sheds and garages. The page then states that all trade and fire prevention permits, giving HVAC, electrical, fire alarm and sprinkler as its examples, must be obtained separately. So a homeowner holding a permit for a renovation does not hold one for the mechanical work inside that renovation, and in the city the person who pulls the HVAC permit is a mechanical license holder, which links the two halves of this page together. The office is at One Park Place, 300 South State Street, 1st Floor. Asking who is pulling the permit, and under whose license, is a fair question on any city job, and the answer tells you whether the person quoting is entitled to do the work at all.

Liverpool, Salina, Solvay and Clay: four towns, four different answers

The optional exemption above is why this county has no single answer, and the differences are not subtle. The Village of Liverpool publishes a list of work requiring a building permit that names the installation of any gas lines or appliance including space heaters, and the installation of any new or replacement furnace, central air conditioning, boiler, gas fireplace or other heating equipment, and it publishes separate HVAC, mechanical and heating appliance applications. In Liverpool the question is settled before it is asked. The Town of Salina's published list includes additions or new heating systems, solid fuel heating devices and gas inserts, but its wording is about additions and new systems rather than about a like for like replacement, so that is a call to the Department of Planning and Development rather than an assumption in either direction. The Village of Solvay publishes examples of work needing a permit which name fireplaces and woodstoves but do not name furnaces, boilers or air conditioning, and absence from a list of examples is not an exemption: the village asks anyone unsure to call Code Enforcement on (315) 468-1679. The Town of Clay, which has the largest housing stock in the county, names building permits as a service but publishes no schedule of the work requiring one, so the only reliable route there is the codes office on (315) 652-3800 extension 172.

DeWitt will not open a permit file without a signed estimate, and that works in your favor

The Town of DeWitt states that with the exception of minor repairs, a permit is needed to upgrade, modify or install any fixed or movable improvements to real property, and advises contacting the Planning and Zoning office wherever there is doubt. What makes DeWitt worth its own paragraph is what a complete application contains: the application form, a copy of a current survey with photographs not accepted, the fee from the schedule, and a signed estimate. That last requirement quietly does something for you. In DeWitt, and by extension for Jamesville addresses that file through DeWitt, a contractor who will not put the number in writing and sign it cannot get the permit either, so the written price stops being something you have to push for and becomes a step in the process. It is worth asking for the same document everywhere else, whether or not the town requires it, because a signed estimate naming the failed part is the single most useful piece of paper in any dispute that follows.

The six questions, in the order worth asking them

Put together, the checkable list for this county is short and none of it is confrontational. First, which municipality is the property actually in, because that decides everything below and an address with a Syracuse mailing address is often not in the city. Second, if it is in the city, which class of mechanical license the firm holds, and whether the name appears on the city's published contractor list. Third, which type of Section 608 certification the person opening the sealed side holds, remembering that a home central system is a high pressure appliance rather than a small one. Fourth, whether they are insured for the work. Fifth, who is pulling the permit, if the municipality requires one, and under whose license. Sixth, a written and signed estimate naming the part. None of those questions requires you to know anything technical, and all six are answerable in one telephone call. We connect homeowners with licensed, insured contractors covering their town, and where the address is inside the city the license that counts is the city's own, with no obligation either way.
