How to Start an HVAC Business in West Virginia

Technical Skills Are the Easy Part

You can install a 20-ton commercial rooftop unit with your eyes half closed, but that competence is invisible to the State of West Virginia until you stack credentials from at least four separate agencies. The gap between "I can do the work" and "I can legally bid on the work" is where most new HVAC business owners stall — usually after they have already signed a lease, printed business cards, and quoted their first project.

West Virginia requires coordination across the Division of Labor (individual certification), the Contractor Licensing Board (business license), the Secretary of State (entity formation), the State Tax Department (tax registration), and every municipal office where you plan to pull permits. Skip any one of these, and a building inspector or state investigator can shut you down on the job site.

Step 1: Secure Your Individual Trade Certification

Before anyone performs physical HVAC work, that person must hold a personal HVAC Technician Certification from the WVDOL. The business-license application separately requires a qualifying individual who has passed the trade exam. The full technician credential requires 2,000 hours of documented field experience and a passing score (70%) on the 80-question ProV trade exam. The annual fee is $75.

If you are still accumulating hours, the Residential Technician credential lets you start working on residential systems while you build toward the full certification. No minimum experience is required to sit for the residential exam.

You will also need EPA Section 608 certification (Universal or Type II minimum) if your work involves refrigerant handling — this is a federal requirement that the state does not waive.

Step 2: Form a Legal Business Entity

Register your business structure with the West Virginia Secretary of State through the One Stop Business Portal. A domestic LLC filing costs $100 and requires designating a physical principal office and a registered agent in West Virginia to receive legal service. Sole proprietorships, partnerships, and corporations are also options — the structure you choose affects personal liability, tax treatment, and how the Contractor Licensing Board processes your application.

Step 3: Register with the State Tax Department

After entity formation, register with the West Virginia State Tax Department via the MyTaxes online portal. The one-time tax registration fee is $30, and you receive a West Virginia Business Registration Tax Number. This number is mandatory for all contractors and subcontractors — it registers you to collect and remit state sales and use taxes and to file income taxes.

Step 4: Secure Insurance and the Wage Bond

The Contractor Licensing Board requires two insurance coverages before it will process your application:

• General liability insurance: Minimum $300,000 per occurrence
• Workers' compensation insurance: Mandatory if you employ anyone; sole proprietors with no employees can request an exemption certificate from the West Virginia Insurance Commissioner

If you plan to hire employees for commercial construction, you also need a wage bond approved by the Attorney General's Office. The bond amount equals one month's gross payroll plus 15%. New contractors can qualify for an exemption by documenting at least one full year of active operation with employees in West Virginia, five consecutive years with employees in another state, holding $100,000 in unencumbered assets, or limiting work to single-family dwellings.

All applicants must submit a notarized Bond Status Affidavit — even if you qualify for an exemption. The application stalls without this form.

Finally, register with WorkForce West Virginia to set up your unemployment compensation account.

Step 5: Pass the Business & Law Exam and Apply for Your Contractor License

With your individual certification, business entity, tax registration, insurance certificates, and bond affidavit in hand, you need to pass the ProV Business & Law exam — 50 questions, 3 hours, open-book, 70% to pass, $59.95 per attempt. The only approved reference is the West Virginia Contractors Licensing Act Study Guide (January 2026 Version).

Submit your formal Contractor License Application to the WVCLB with all supporting documentation and a $90 licensing fee. Your application must designate a "qualifier" — an owner, officer, member, or full-time employee who has passed the trade exam on behalf of the company. Processing typically takes 14–30 days.

Once issued, your contractor license number must appear in all advertisements, public bids, and binding contracts. A physical copy must be posted at every active job site.

Step 6: Register Locally and Pull Your First Permit

A state contractor license authorizes you to work statewide but does not bypass municipal requirements. In every city where you operate, you will need to:

• Register your state license with the local building department
• Obtain a local business license (typically $20/year)
• Set up a Business & Occupation (B&O) tax account (rates vary by municipality; Charleston and Huntington use 2% in the cited examples)
• Pull trade-specific mechanical permits before starting each project

Cities like Charleston impose a minimum $100 fine for starting work without a permit, plus an automatic three-month suspension of your city license. Huntington charges a $5/week City Service Fee per employee on top of its B&O tax.

The Sequence Matters

The order is not optional. Before anyone performs physical HVAC work, that person's individual certification must be active. The WVCLB will not process your application without insurance certificates and the bond affidavit. And local building departments will not issue mechanical permits to an unregistered business, no matter how current your state license is.

The West Virginia HVAC License Guide maps this entire startup sequence — from logging your first supervised hours through pulling your first city permit — so you complete each step with the right agency at the right time.
