  2. EPA Section 608 Certification (for refrigerant handling)

    Section 608 of the Clean Air Act prohibits knowingly venting ozone-depleting refrigerants and their substitutes while maintaining, servicing, repairing or disposing of air conditioning and refrigeration equipment, and technicians who do that work or buy regulated refrigerant must hold EPA Section 608 technician certification. There are four types: Type I for servicing small appliances, Type II for high- and very-high-pressure appliances other than small appliances and motor vehicle air conditioners, Type III for low-pressure appliances, and Universal for all types. Choose the type that matches the equipment you will work on, or Universal to cover everything. Exams must be administered by an EPA-approved certifying organisation, and the credential does not expire. Motor vehicle air conditioning work is certified separately under Section 609.

  1. NJ State Board of Examiners of HVACR Contractors — Master HVACR Contractor License

    HVAC work in New Jersey must be performed by or under a licensed Master HVACR Contractor. The license is issued by the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors within the Division of Consumer Affairs — not the Department of Labor, and not the Home Improvement Contractor (HIC) registry, which is a separate consumer-protection registration that does not authorize HVACR contracting. You must be at least 21, satisfy the education and experience route (a formal U.S. Department of Labor apprenticeship, or a qualifying bachelor's degree) plus one journeyman year in the trade documented by W-2s, and pass the Board examination. Applications are filed online only. To run an HVACR business you must also carry a $3,000 surety bond and a $500,000 general liability certificate, and you must still pull municipal permits and inspections under the Uniform Construction Code. Technicians handling refrigerants separately need federal EPA Section 608 certification.

    Official government source

    $100 non-refundable application fee, then a $160 initial license fee ($80 if paid in the second year of the biennial period), plus $25 for the initial pressure seal. Renewal is $160 every two years, with a $50 late fee (N.J.A.C. 13:32A-6.1).Apply online, then the Board reviews your documents and schedules the exam. The $160 licensing fee is invoiced only after the application is approved and you pass the exam, so the total elapsed time is driven by the Board's exam schedule. Licenses then renew biennially with continuing education.

  2. City of Paterson Health & Human Services — Mercantile License

    Paterson city ordinance requires businesses operating in the city to register and obtain a Mercantile License, administered by the Mercantile Licensing division of the Department of Health & Human Services. A mercantile inspector visits the business as part of the process, which the city describes as a consumer-protection function that also provides technical assistance to businesses. Note that Paterson has no 'Department of Business Administration' — the city's departments are Administration, Community Development, Economic Development, Finance, Health & Human Services, Legal, Municipal Court, Public Safety and Public Works. Businesses in regulated industries need additional permits from the relevant division, such as retail food licensing from the Division of Health or construction permits from UCC Construction/Buildings.

    Official government source

    Paterson does not publish a Mercantile License fee schedule online; the fee is set by city ordinance and varies with the type of business. Contact Mercantile Licensing through City Hall at 973-321-1600 for the amount that applies to you.Paterson's permitting and licensing system is being moved online. Apply through Mercantile Licensing and allow time for the mercantile inspection before you open.

  3. City of Paterson UCC Construction/Buildings — Mechanical/HVAC Construction Permit (per project)

    Each HVAC installation, replacement or major repair requires a construction permit covering the applicable mechanical work from the City of Paterson's UCC Construction/Buildings division, 111 Broadway (973-321-1549), whose building, electrical, plumbing and fire inspectors are licensed by the NJ Department of Community Affairs. Under the New Jersey Uniform Construction Code these permits are strictly municipal — Passaic County has no construction-permitting role. Applications use the State's standardized UCC forms, and a final inspection is required before closeout.

    Official government source

    Set by Paterson's construction fee ordinance and calculated from the scope and value of the work; confirm the current fee schedule with UCC Construction/Buildings at 973-321-15491–5 business days
