How to Start an HVAC Business in Montana (2026)

Last updated: February 26, 2026

Starting an HVAC business in Montana does not require passing a state HVAC contractor licensing exam – Montana has no state HVAC license. Instead, HVAC contractors must register with the Montana Department of Labor and Industry (DLI) either as a Construction Contractor (CCR, $70 for businesses with employees) or obtain an Independent Contractor Exemption Certificate (ICEC, $125 for sole proprietors). Federal EPA Section 608 certification is required for any technician working with refrigerants. Workers’ compensation is mandatory from the first employee. This guide covers every registration, certification, and insurance requirement to legally operate an HVAC company in Montana.

How to Start an HVAC Business in Montana (Step by Step)

Step 1: Form Your LLC

File an LLC with the Montana Secretary of State at biz.sosmt.gov for $35. An LLC provides personal liability protection from construction-related claims and workplace injury lawsuits. You will need an EIN (free at irs.gov) to open a business bank account and manage payroll.

Step 2: Secure Workers’ Compensation Insurance

Workers’ comp insurance must be in place before you can register as a construction contractor with Montana DLI. Montana requires workers’ compensation for any employer with one or more employees, including part-time workers. HVAC work involves significant physical risk (electrical, confined spaces, rooftop work), so proper coverage is essential both legally and financially.

Get a quote from a private insurer or through the Montana State Fund at montanastatefund.com. HVAC contractors typically carry workers’ comp rates in the moderate-to-high range given the physical hazards of the trade.

Step 3: Register with Montana DLI

Montana requires all HVAC contractors to register through the DLI Employment Relations Division. There are two pathways depending on your structure:

Option A: Construction Contractor Registration (CCR)

• Required for: LLCs, corporations, and any business with employees
• Fee: $70 (non-refundable, valid 2 years)
• Requires: Proof of current workers’ compensation insurance
• Agency: Montana DLI Employment Relations Division
• URL: erd.dli.mt.gov/work-comp-regulations/montana-contractor
• Phone: (406) 444-7734

Option B: Independent Contractor Exemption Certificate (ICEC)

• Required for: Sole proprietors with no employees performing HVAC work
• Fee: $125 (valid 2 years)
• Requires: Notarized application plus proof of independent business entity status
• Agency: Montana DLI Employment Relations Division (same office as CCR)

Once registered, your CCR or ICEC number may be required by property owners, general contractors, and local permit offices before allowing work to proceed. Renew every 2 years to stay in compliance.

Step 4: EPA Section 608 Certification

The federal Clean Air Act requires that any technician who purchases, handles, or recovers refrigerants (including HFCs, HCFCs, and CFCs used in HVAC and refrigeration systems) must hold a valid EPA Section 608 certification. This is a federal requirement that applies in all 50 states – Montana’s lack of a state HVAC exam does not exempt Montana technicians from this federal certification.

EPA 608 certification types:

• Type I: Small appliances (sealed systems, under 5 lbs refrigerant)
• Type II: High-pressure appliances (most residential A/C and heat pumps)
• Type III: Low-pressure appliances (large commercial chillers)
• Universal: Covers all three types – the most common choice for HVAC technicians

Pass the exam through any EPA-approved testing organization. ESCO Institute (epa608.com), NATE, and various community college vocational programs offer proctored exams. The Universal certification exam fee is typically $20-$50. Certification does not expire and does not require renewal.

Step 5: Get a Local Business License

Most Montana cities require a local business license before you may conduct business within their limits. Contact the city or county where you will be headquartered:

• Billings, Missoula, Great Falls, Bozeman, Helena: Each has a city business license. Contact the city clerk or finance department.

Some municipalities may also require a local contractor registration or permit to pull building permits – check with local building departments in your primary service area.

Step 6: Register for Employer Taxes

Once you hire employees, register with:

• Montana Department of Revenue: For income tax withholding. Use the TAP portal: dorpowerappsportal.powerappsportals.us
• Montana UI Division: For unemployment insurance. Register at uieservices.mt.gov.
• IRS: For federal payroll taxes (FICA, FUTA). Manage through your EIN.
• New hire reporting: Report new employees within 20 days at mt-newhire.com.

Step 7: Pull Building Permits for Each Job

HVAC installation and replacement work typically requires a local building permit. This is a per-job requirement, not a one-time business registration. Permit requirements and fees vary by city and county. The local building department in each jurisdiction controls permit issuance. Pulling permits protects you legally and ensures work is inspected and code-compliant. Never perform major HVAC work without the required permit.
