How to Start an HVAC Business in New York (2026)

Last updated: February 25, 2026

Starting an HVAC business in New York is unique because there is no statewide HVAC license – licensing is handled entirely at the city and county level. This means your requirements depend heavily on where you work. NYC has the most complex system with multiple DOB and FDNY licenses, while many upstate areas have no HVAC-specific license at all. What is universal across the state is EPA Section 608 certification for handling refrigerants, strict workers’ compensation requirements, and compliance with Home Improvement Contractor laws for residential work.

How to Start an HVAC Business in New York (Step by Step)

Step 1: Get EPA Section 608 Certification (Federal – Mandatory)

Every HVAC technician who handles refrigerants must hold EPA Section 608 certification under the Clean Air Act. This is federal law, not optional.

Certification Type	Covers	Who Needs It
Type I	Small appliances (under 5 lbs refrigerant)	Window AC, PTAC technicians
Type II	High/very high pressure appliances	Central AC, heat pump technicians
Type III	Low-pressure appliances	Centrifugal chiller technicians
Universal	All of the above	Recommended for business owners

The exam costs $20-$40 through EPA-approved testing providers, with 25 multiple-choice questions per section (70% passing score). Credentials never expire.

Step 2: Form Your Business Entity

Register an LLC with the New York Department of State ($200). Complete the publication requirement within 120 days. Apply for a free federal EIN from the IRS.

Step 3: Get Local HVAC and Home Improvement Contractor Licenses

Since New York has no statewide HVAC license, you must check requirements for each city and county where you plan to work. HVAC work falls under the Home Improvement Contractor definition in jurisdictions that have HIC licensing:

Jurisdiction	License Fee	Bond/Trust	Exam?
New York City (DCWP)	$25-$100 + $50 exam	$20,000 bond or $200 trust fund	Yes
Nassau County	$650 (2-year) + $50 restitution fund	Required	No
Suffolk County	$200/year	Required	Yes
Westchester County	$750 (eff. Jan 2026)	Required	No
Putnam County	$250-$300 (2-year)	$25,000 bond	No
Rockland County	$325	Required	Yes

Outside these six jurisdictions: No county-level HIC license is required in most upstate areas, but statewide Article 36-A contract requirements still apply (written contracts for work over $500, escrow deposits, 3-day cancellation right).

Upstate City HVAC Licenses

Some upstate cities have their own HVAC-specific licensing:

Syracuse: Class A Master ($200, 10 years experience), Class B Limited ($100, 5 years), Class C Residential ($100, 5 years)
Buffalo: Class IA ($125), Class IB ($100), Class II ($75) – requires EPA Universal and 2 years experience
Albany: Class A or B professional license from city Department of Buildings
Rochester, Yonkers, and others: Check with local building department

Step 4: Get NYC-Specific Licenses (If Working in NYC)

NYC has the most complex HVAC licensing structure in the state. Depending on your services, you may need:

FDNY Q-01 Certificate of Qualification (Refrigerating Systems)

Required to operate any FDNY-permitted refrigerating system. A Q-01 holder must be in the building at all times while the system runs.

Requirements: 200-hour course from FDNY-certified school OR 1 year practical experience, plus EPA Universal certification
Written exam (Z-51): $60
Practical exam (Z-52): $225
Application fee: $60
Renewal: $15 every 3 years

NYC DOB Oil Burner Equipment Installer License

Required for oil-fired heating equipment installation and service:

Class A: 4 years experience, written ($585) + practical ($530) exams, seal fee ($100). Covers all fuel oils.
Class B: 3 years experience, same exams. Covers No. 1-4 fuel oils only.

Step 5: Get Insurance and Bonding

Workers’ compensation is mandatory for all employers. HVAC falls under class code 5537, with average rates of approximately $3.14 per $100 of payroll. For a small crew with $200,000 in annual payroll, that’s roughly $6,280/year.

You also need:

General liability insurance: $1 million per occurrence / $2 million aggregate – required for most permits and contracts. Estimated $2,500-$5,000/year.
Commercial auto insurance: $1,500-$3,000/year for service vehicles
Inland marine (tools/equipment): $500-$1,500/year
Disability benefits (DBL) and Paid Family Leave (PFL): Mandatory for all employers
Surety bonds: Required amounts vary – NYC HIC requires $20,000, Putnam County requires $25,000

Step 6: Understand NYS DEC Refrigerant Regulations

New York has adopted Part 494 refrigerant regulations – stricter than federal rules. Key points:

Bans specific high-GWP refrigerants and equipment on a phased schedule
By January 1, 2034: Residential and light commercial AC/heat pump systems using refrigerants with GWP20 > 10 are prohibited
Systems with 50+ lbs of refrigerant require leak management programs
Systems with 1,500+ lbs require automatic leak detection
