How to Start an HVAC Business in West Virginia: Technician Certification and Contractor Licence

Starting an HVAC business in West Virginia involves two credentials that new owners often confuse. The first is personal. Anyone who does hands-on HVAC work in the state needs an HVAC technician certification from the Division of Labor, a requirement in place since January 1, 2016 under W. Va. Code 21-16. The second belongs to the company. Once a single project reaches $5,000 on residential work or $25,000 on commercial work, the business needs a contractor license with an HVAC classification from the Contractor Licensing Board under W. Va. Code 30-42. Around those two sit the business filings: the Secretary of State formation, the State Tax Division registration and whatever your city requires.

Informational only: This article explains how the process generally works. It is not legal or tax advice. Fees, thresholds and deadlines change, so confirm each one on the agency page linked at the end before you pay or file. Before you form the company, sign large contracts or hire employees, talk with a West Virginia attorney and a certified public accountant (CPA).

Materials and information you need before you start

Gather these before you open a single form. Most delays come from missing paperwork, not from the state.

• Dated proof of HVAC work. Job logs, invoices, training certificates and an employer letter. The full technician level requires at least 2,000 hours of HVAC work, training and experience.
• A certification application and the fee for the level you qualify for (see Step 1).
• Two or three name options checked in the Secretary of State business search at apps.sos.wv.gov/business/corporations.
• Articles of Organization (Form LLD-1) and the $100 filing fee.
• A federal Employer Identification Number (EIN) from the IRS, which you need for banking and payroll.
• A city business license application and the contact at your city hall for its gross receipts business and occupation tax.
• Insurance quotes. Ask your agent what coverage your contracts and the contractor license will require, and confirm the requirement with the Contractor Licensing Board.
• An EPA Section 608 refrigerant certification if you will handle refrigerant. This is a federal credential and is separate from the West Virginia certification.

Step 1: Pick your technician certification level

The Division of Labor issues three HVAC technician levels. Match the level to your actual hours, because applying at the wrong level wastes time and money.

• Technician in Training, $25. For people with fewer than 2,000 hours. There is no written exam. You need only the application and the fee. Trainees work under direct supervision.
• HVAC Technician, $75. For people with at least 2,000 hours of HVAC work, training and experience. This level covers residential and nonresidential work and requires a written exam administered by Prov Inc.
• HVAC Residential Technician, $50. Covers residential work and requires a written exam administered by Prov Inc. Confirm the experience requirement for this level on the Division of Labor site before you apply.

Ongoing costs are small but real. A duplicate card costs $10. A $25 late fee applies after 15 days, so confirm on the Division of Labor site what that period is measured from and set a renewal reminder.

Trainees must work under the direct supervision of a certified technician. A certified technician may supervise no more than 4 trainees on a residential project and no more than 2 trainees on a commercial project. Plan your crew around those limits before you hire.

W. Va. Code 21-16-3(d) lists a few exemptions: work on your own single-family home, plant employees, electrical or plumbing-only work within the license you hold, and routine maintenance. Read the exact statutory text before you rely on any of them. A company that sells installs to customers should not assume its technicians fit an exemption.

Step 2: Form the company

Most small HVAC shops choose a limited liability company (LLC). The Articles of Organization (Form LLD-1) cost $100 and are filed through the WV One Stop Business Portal at business4.wv.gov. Online filings add a $1.00 portal processing fee. Standard processing takes 5 to 10 business days. If you need speed, the Secretary of State offers expedited options on top of the filing fee: in-person same day for $25, next business day for $25, 2 hour for $250 and 1 hour for $500.

The name must include "limited liability company," "limited company," or one of the abbreviations LLC, L.L.C., L.C. or LC. "Ltd." and "Co." are permitted abbreviations for "Limited" and "Company." A name such as Ridgeline Heating and Cooling LLC works. The name must also be distinguishable from every other name already registered or reserved. To hold a name while you finish paperwork, reserve it for 120 days for $15 at sos.wv.gov/reserveregister-business-name.

A registered agent is optional. Form LLD-1 asks for an agent for service of process "if any," and the Secretary of State can accept service on the company's behalf. If you name yourself or a local agent, file Form AAO for $15 whenever that information changes.

The LLC's recurring filing is the annual report, which costs $25 and is filed between January 1 and June 30 each year after the year you registered. Filing after June 30 costs $75 because of a $50 late fee.

For taxes, West Virginia has repealed its business franchise tax. An LLC pays no state franchise tax and, as a pass-through entity, no corporation net income tax. The owners report income on the personal income tax, which runs from 2.11% to 4.58% for tax year 2026. A corporation instead files Articles of Incorporation (Form CD-1) for $100, pays the 6.5% corporation net income tax and files a $25 annual report, with a $50 late fee for for-profit companies. For most single-owner HVAC shops the LLC is the simpler choice, but confirm that with a CPA.

Step 3: Register a DBA if you will trade under another name

If the company will advertise as something other than its legal name, such as "Ridge Air," file a trade name registration (DBA) with the Secretary of State, not a county clerk. An LLC files Form NR-3 and pays $25, plus the $1.00 online processing fee if filed through the portal. Individuals and sole proprietors file Form TN-1 with no filing fee. Start at the Secretary of State trade name page.

Step 4: Get the State Tax Division Business Registration Certificate

West Virginia has no general statewide business license. The closest thing is the Business Registration Certificate from the West Virginia Tax Division. Every individual or business entity must hold one before doing business, and it costs $30 one time. Apply on Form WV/BUS-APP or online at business4.wv.gov. A separate certificate is required for each fixed business location. It stays valid until the business name, location or ownership changes, at which point you update it. Your Secretary of State filing does not replace it.

If you will sell taxable items or services, register for a sales tax permit at the Tax Division business registration page. The state sales tax rate is 6%. Ask the Tax Division which parts of your invoices, such as parts, labor and service calls, are taxable before you set your pricing.

Step 5: Check city licenses, B&O tax and local sales tax

This is where most new owners get surprised. The state business and occupation (B&O) tax applies only to utilities. The gross receipts B&O tax that reaches HVAC shops, contractors and service businesses is levied by cities. Cities also issue their own business license and charge a weekly per-worker city service fee.

West Virginia has 230 incorporated places. Today 101 municipalities add a 1% sales tax to the 6% state rate, and that number rises to 107 from January 1, 2027. Rates and fees differ from city to city, so contact the city clerk or treasurer where your office or shop is located, and ask whether work you perform inside each city limit triggers its tax. Get the answer in writing before you quote a job in that city.

Step 6: Obtain the contractor license

Once a project reaches $5,000 on residential work or $25,000 on commercial work, the company needs a contractor license with an HVAC classification from the Contractor Licensing Board. The thresholds apply to the whole project. Splitting one job into smaller contracts does not change the requirement.

Before you file, check with the Contractor Licensing Board on the application, fees, examination, experience and insurance requirements. Ask directly whether the HVAC classification requires a certified technician to qualify the company, because that determines whether your own technician credential is the foundation of the company license.

Step 7: Confirm the other trades on the job

HVAC work often touches electrical and plumbing. The State Fire Marshal licenses electricians, and the Division of Labor licenses plumbers. Your HVAC certification does not cover electrical work outside a license you hold. If your installs require line-voltage connections, confirm with the State Fire Marshal who must make those connections before you bid the job.

Step 8: Prepare for employees

Before your first hire, ask the Tax Division what employer accounts you need, and confirm the supervision and certification rules for every person on the crew with the Division of Labor. Keep a supervision log from the first day. Trainees and their supervisors should each know the ratios in Step 1.

What you can reasonably expect

If your filings are complete and accurate, the Secretary of State's standard processing typically takes 5 to 10 business days, and expedited options can shorten that. Once your entity, Tax Division certificate, city license and technician credential are in place, you are usually positioned to bid residential work. Commercial bids should wait until your contractor license process is complete, and that timing depends on the Contractor Licensing Board. Plan your first large commercial job around its timeline rather than the filing date.

Common mistakes to avoid

• Treating the Secretary of State filing as a license. It is a filing. You still need the Tax Division certificate and any city license.
• Assuming your technician card covers the company. The card is personal. The company needs its own contractor license once a project reaches the threshold.
• Splitting one job into smaller contracts to stay under the $5,000 or $25,000 line.
• Forgetting the city. The state has no general business license, so city licensing and the gross receipts B&O tax are the surprise costs.
• Exceeding the trainee ratio of 4 trainees per technician on residential work or 2 on commercial work.
• Missing the June 30 annual report, which rises from $25 to $75 after the deadline.
• Choosing a name without an allowed ending such as LLC, or using a trade name without filing a DBA.
• Relying on an exemption without reading W. Va. Code 21-16-3(d) in full.
• Handling refrigerant without EPA 608 certification. The federal credential is separate from West Virginia's.

Where to confirm every figure

• West Virginia Secretary of State business filings: sos.wv.gov/business
• WV One Stop Business Portal: business4.wv.gov
• West Virginia Tax Division: tax.wv.gov
• West Virginia Division of Labor, technician certification: labor.wv.gov
• West Virginia Small Business Development Center, for planning help: wvsbdc.com

Confirm the current fees and thresholds on those pages before you file. Because the contractor license, city taxes and entity structure each carry long-term consequences, have a West Virginia attorney and a CPA review your plan before you sign a lease, a vehicle loan or your first commercial contract.
