How to Start an HVAC Business in West Virginia (Step by Step)

Step 1: Understand West Virginia’s Two-Tier HVAC Licensing System

West Virginia regulates HVAC through two separate agencies:

Required for HVAC businesses taking on projects of $5,000+ on residential or $25,000+ on commercial
Contact: (304) 558-7890 | wvclboard.wv.gov

Step 2: Obtain Your WV HVAC Technician Certification

There are three certification levels issued by the WV Division of Labor:

Certification	Scope	Requirements	Fee
HVAC Technician	Residential and non-residential (commercial)	2,000 hours experience + pass written exam	$75 initial / $75 renewal
HVAC Residential Technician	Residential systems (with limited commercial)	Experience + pass written exam	$50 initial / $50 renewal

Supervision limits for Technicians in Training:

Maximum 4 Trainees per supervising Technician on residential projects
Maximum 2 Trainees per supervising Technician on commercial projects
Trainees may not perform HVAC work independently

Step 3: Obtain Your EPA 608 Certification

Federal law (Clean Air Act, Section 608) requires anyone who purchases, uses, or handles refrigerants to hold an EPA 608 certification. West Virginia does not add additional state requirements on top of the federal mandate.

EPA 608 types:

Type I: Small appliances (5 pounds of refrigerant or less)
Type II: High-pressure systems (common in residential HVAC)
Type III: Low-pressure systems (commercial chillers)
Universal: Covers all types — recommended for most HVAC technicians

Find EPA 608 testing through NATE, HVAC Excellence, or local HVAC training centers. Exam cost: approximately $20-$50. The certification does not expire.

Step 4: Obtain a WV Contractor License (If Needed)

If your HVAC business will take on projects above certain dollar thresholds, you need a contractor license from the WV Contractor Licensing Board:

Residential threshold: Projects of $5,000 or more
Commercial threshold: Projects of $25,000 or more
License fee: $90 initial application + $90 annual renewal

Contractor license requirements:

Pass a trade exam (HVAC) AND a business and law exam through Prov Exam, Inc.
The exam taker must be an officer, member, owner, or full-time W-2 employee of the business
Must register with WV SOS and obtain Tax Department business registration number before applying

Bond requirements (commercial construction businesses):

A wage bond is required for commercial construction businesses with employees
Exempt if: residential-only business; or 5+ years in business with $100,000+ in assets; or subsidiary of a qualifying parent company

Step 5: Business Setup and Insurance

LLC formation: $26 through the WV One Stop Business Portal

Business Registration Certificate: $30 from the WV State Tax Department

Required insurance:

Workers’ compensation: Required for all employees; WV has no small-employer exemption. Private carriers available through the WV Insurance Commissioner’s office.
General liability insurance: Not state-mandated but required by most municipalities for permits and by commercial clients. Typical minimum: $300,000-$1,000,000 per occurrence.
Commercial auto insurance: Required for service vehicles.

Step 6: Register for Employer Taxes

EIN: Free from the IRS at irs.gov
Unemployment insurance: Register with WorkForce West Virginia
