How to Start an HVAC Business in Massachusetts (2026)

Last updated: February 25, 2026

Starting an HVAC business in Massachusetts requires multiple trade-specific licenses – there is no single “HVAC license.” Depending on the work you perform, you may need a Refrigeration Technician License, Gas Fitter License, Sheet Metal Worker License, Construction Supervisor License, and Home Improvement Contractor (HIC) registration. You’ll also need EPA Section 608 certification for refrigerant handling. Massachusetts is one of the most heavily licensed states for HVAC work, but this also means less competition from unlicensed operators. LLC formation costs $500-$520, and the annual report is another $500-$520/year. This guide covers every requirement from official Massachusetts sources.

Four pathways based on combinations of apprentice hours (2,000-6,000) and coursework (250-1,000 hours). Requires EPA Universal CFC certification. To operate an HVAC business, you’ll need the Refrigeration Contractor License ($150) – requires journeyman license + 2,000 hours additional experience + 100 hours education.

Gas Fitter License (Gas Furnaces & Piping)

Required for all gas piping and gas-fired HVAC equipment work. Issued by the Board of State Examiners of Plumbers and Gas Fitters. Application: $31, license: $52.

EPA Section 608 Certification (Federal)

See EPA Section 608.

Step 2: Form Your Business Entity

Register an LLC with the Secretary of the Commonwealth ($500 by mail, $520 online). Apply for a free federal EIN from the IRS. File a Business Certificate with your city/town clerk if using a trade name ($25-$65).

Step 3: Register as a Home Improvement Contractor (HIC)

All contractors performing work on existing 1-4 unit residential properties must register with the Office of Consumer Affairs and Business Regulation (OCABR). No exam required. Register through the MA Contractor Hub.

Step 4: Get a Construction Supervisor License (If Applicable)

If you supervise building construction, reconstruction, or alteration, you need a Construction Supervisor License from the Board of Building Regulations and Standards (BBRS). Requires 3 years of construction experience. Exam: $100 (PSI). License: $150.

Step 5: Get Insurance Coverage

General liability insurance is required for HIC registration and most commercial contracts. Typical HVAC coverage: $1M per occurrence. Cost: $1,500-$5,000/year depending on revenue and risk.

Workers’ compensation is mandatory for any employer with employees. HVAC businesses fall under class code 5537. Coverage is through private carriers regulated by the DIA. Rates are set by WCRIBMA.

Step 6: Register for State Taxes

Register through MassTaxConnect. Labor and services are generally exempt from Massachusetts 6.25% sales tax. However, materials and equipment sold to customers are taxable. Heat pump systems for primary/auxiliary heating in residential properties are exempt from sales tax. If hiring: unemployment insurance (2.42% on $15,000), PFML (0.88% of wages), and income tax withholding (5%).
