Alabama's Contractor License Qualifier Rules: The HVAC Bond, the W-2 Statute and the Plumbing One-Company Limit

Alabama requires every new certified heating, air conditioning, or refrigeration contractor to post a $20,000 performance bond before the Board of Heating, Air Conditioning and Refrigeration Contractors will issue a certificate, the figure set under Rule 440-X-3-.04(5) inside the $25,000 annual cap the enabling statute allows. That bond is only the entry fee. The same chapter of Alabama law goes further than any other state we track by defining the required qualifier through a federal tax form.

At a glance

• New HVAC and refrigeration applicants post a $20,000 performance bond (Ala. Admin. Code 440-X-3-.04(5)), inside a $25,000 statutory cap (Code of Ala. § 34-31-30)
• The HVAC qualifier must be an actual employee who works 30 or more hours a week and receives a Form W-2 for all earnings (Code of Ala. § 34-31-18(12))
• The Plumbers and Gas Fitters Examining Board limits a principal master plumber or gas fitter to one company, with no exception (Rule 720-X-12-.02(2))
• Both boards require 5 days' notice when a qualifier quits, and both cut off contracting the same day (Rules 440-X-3-.08, 720-X-12-.03)
• Boiler and pressure vessel installation runs through a separate state permit, not an HVAC board certification

New to Alabama contractor licensing? Start with the Alabama contractor license requirements, and see how to get a contractor license in every state for the national picture. This page covers the two boards that actually govern who may hold an Alabama qualifier credential: Heating, Air Conditioning and Refrigeration, and Plumbing and Gas Fitting.

Why Alabama Has Two Qualifier Regimes

Alabama does not run construction licensing through a single agency. Plumbing and gas fitting sit with the Alabama Plumbers and Gas Fitters Examining Board under Title 34, Chapter 37. HVAC and refrigeration sit with the Alabama Board of Heating, Air Conditioning and Refrigeration Contractors under Title 34, Chapter 31, headquartered at 100 North Union Street in Montgomery. Electrical work sits with the Alabama Electrical Contractors Board, and general building work sits with the Licensing Board for General Contractors.

Each board wrote its own answer to the same question: what must the individual holding this credential actually be, relative to the company using it? They arrived at the same place by different routes, and on the core employment test, both converge on the same two permitted relationships: employ the qualifier, or own the company.

The HVAC Bond and Certification Fees

Alabama's HVAC bond is the figure driving most of the search traffic to this page, so it belongs up front, with the rest of what the Board's fee schedule requires.

Rule 440-X-3-.04(5) requires every new heating and air conditioning, or refrigeration, applicant to provide the Board a performance bond of $20,000 before certification. Proof of that bond may be required again during renewal. The enabling statute, Code of Ala. § 34-31-30, sets a ceiling rather than a fixed number: the Board may require a bond "not to exceed twenty-five thousand dollars ($25,000) per year for all active certified contractors." The $20,000 figure is the Board's current rule amount inside that cap, not a separate or competing number.

The bond sits alongside a published fee schedule the Board adopted effective October 14, 2024:

• Fees apply equally to heating and air conditioning certificates and to refrigeration certificates.
• Certificates expire December 31 each year and must renew by then to avoid the late fee.
• Duct air tightness testing registration runs on its own $50 fee, separate from contractor certification.

None of this answers "what does an Alabama HVAC license cost to maintain" with one tidy number, because the honest answer is a full time W-2 employment relationship plus these fees plus the bond premium, not a figure a guide can hand you in the abstract. We cover that further down.

What About a "Licensed Boiler Contractor"?

Alabama does not issue a credential called a licensed boiler contractor, which is likely why that search lands on a qualifier page like this one instead of a dedicated board page.

Boiler and pressure vessel work in Alabama runs through the state's Boiler Safety program, operated by the Inspections Division of the Alabama Department of Workforce, the successor to the Department of Labor. It is not an HVAC board function. The company or person responsible for installing a boiler or pressure vessel, including a water heater over 200,000 BTU or more than 120 gallons, must first obtain an installation permit for a $50 fee, using the Request to Install a Boiler or Pressure Vessel form. That permit authorizes a specific installation; it is not a standing contractor license.

Where boiler work overlaps with heating and air conditioning work, such as hydronic heating tied into a building's HVAC system, the installer still needs HACR certification for that portion of the job. A liquefied petroleum gas appliance connection may instead fall under the Alabama Liquefied Petroleum Gas Board. Check scope with the Inspections Division and the HACR Board before assuming either one covers your job.

Regime One: HVAC, The Person in Responsible Charge

The company never holds the certificate

Under rule 440-X-3-.04(6), a partnership, corporation, business trust, or other legal entity applies for HVAC or refrigeration certification through a person in responsible charge. The application must name the entity's partners, officers and directors, trustees, or members, and must establish that the person in responsible charge is legally qualified to act for the organization in all matters connected with the business.

Then:

"The … certification by the Board issued upon such application described in this Rule shall be issued in the name of the person in responsible charge and shall include the name of the business organization engaged in the … business."

The certificate is issued in the individual's name, carrying the company's name. The company operates on a credential that legally belongs to a named human being.

What that individual must be

Rule 440-X-3-.09(1) requires that the person in responsible charge be a regularly employed person, the § 34-31-18(12) definition quoted below, and adds:

• must work an average of 30 or more hours per week as a full-time employee;
• may alternatively be an owner, partner, or corporate officer of the entity;
• must possess the requisite skill, knowledge, and experience;
• must have the responsibility to supervise, direct, manage, and control the installation, service, or repair activities of the entity;
• and the Board "shall examine the technical and personal qualifications of the person in responsible charge and may investigate and/or examine that person's qualifications."

"REGULARLY EMPLOYED PERSON. An individual who meets all of the following conditions: a. Is an actual employee of the business, not an independent contractor. b. Works an average of 30 or more hours per week for the heating, air conditioning, or refrigeration business. c. Is not paid as an independent contractor. d. Receives a Form W-2, Wage and Tax Statement, for all earnings."

Code of Alabama 1975, § 34-31-18(12)

We track qualifier-employment language across every state that regulates it. This is the only statutory definition we have found that names the W-2 itself. There is no interpretation under which an Alabama HVAC person in responsible charge is paid on a 1099.

Note the structure. The permitted relationships are employment or ownership. There is no third category.

The second-entity test

Rule 440-X-3-.09(2) allows a person in responsible charge to qualify a second entity, and then makes the requirements ones that a detached license holder cannot meet. The individual is required to appear at a Board meeting in person and present:

• evidence of ownership in the additional entity,
• evidence of the ability to supervise, direct, manage and control it,
• evidence of financial responsibility for it,

plus an additional licensing fee and a bond in the amount required for certified contractors under these Rules, currently $20,000. And: "It is entirely within the Board's discretion to allow or disallow the additional business entity to be certified."

Ownership. Financial responsibility. A personal appearance. Unreviewable discretion. That is a rule written for one owner running two affiliated companies, not for one certificate serving unrelated clients.

And a flat statutory prohibition

Section 34-31-24(a)(3): "A contractor licensed under this chapter may not permit the use of his or her license by any other person."

Section 34-31-24(a)(1) reaches further than most people assume: no person may advertise, solicit, bid, obtain permits, do business as, or perform the function of a certified contractor unless the person in responsible charge is a certified contractor. Advertising and bidding are regulated acts, not just installing equipment.

Violation is a Class A misdemeanor under § 34-31-32(a). The Board may also levy administrative fines up to $2,000 per violation and issue cease and desist orders; if a person fails to comply immediately, the Board may obtain an injunction that is not subject to being released on bond.

Regime Two: Plumbing, The Principal Master

Every company registers before it works

Under § 34-37-6(b) and Rule 720-X-17-.01, every legal entity engaging in the business of plumbing and/or gas fitting in Alabama must register annually with the Plumbers and Gas Fitters Examining Board, paying all prescribed fees first. Business registration runs $25 a year, with a $25 late penalty if it lapses.

The Board defines the principal master as the individual responsible for the contracting, superintending, installation, maintenance, or repair of plumbing or gas fitting systems for a legal entity, "who is actively and continuously connected with the conduct of the business, and is responsible to the board for those responsibilities." The statutory hook is § 34-37-1(13).

What "actively and continuously connected" means in practice

Rule 720-X-12-.02(1) converts the phrase into three tests. To be registered as principal master plumber, an individual must:

1. be duly registered and certified by the State of Alabama as a master plumber;
2. be an active employee of the legal entity and not an independent contractor; and
3. provide verifiable documentation to substantiate the above as requested by the board or board staff.

That third test is the enforcement mechanism. The Board can ask for proof at any time, and the burden sits on the licensee.

One entity. Full stop.

"No individual shall be registered as the principal master plumber for more than one legal entity regulated by the board.", Rule 720-X-12-.02(2)

Rule 720-X-13-.02(2) imposes the identical limit on the principal master gas fitter.

There is no dual-entity exception on the plumbing side. Not a narrow one like HVAC's, none at all. Where the HVAC board built a tight ownership-based door, the plumbing board built a wall.

The Departure Rule: Both Boards Cut Contracting the Same Day

Alabama's HVAC board and its Plumbing and Gas Fitters board apply nearly the same departure procedure, not two different ones. Rule 440-X-3-.08 on the HVAC side and Rule 720-X-12-.03 on the plumbing side use the same notice windows and the same immediate cutoff.

When a qualifier is terminated, laid off, or resigns, under either board:

1. Both the departing qualifier and the entity must notify the board within five days, each on the prescribed form.
2. The entity must immediately stop entering new contracts, verbal or written.
3. Every certificate holder who was operating under that qualifier's certification must immediately stop installation, service, and repair work.
4. The departing qualifier may not act in that capacity for any employer until the board has approved a new qualifier for the old entity and, separately, approved the departing individual for a new one.

Neither board grants a waiver or a transition period on this track. Revenue stops the day the resignation lands and stays stopped until a replacement is approved.

When a qualifier dies or becomes incapacitated:

Both boards give the entity 45 days to notify them in writing, with a death certificate or a physician's attestation, and a request filed later than that may be denied after a show cause hearing. The mechanism differs after that point. The plumbing board lets the entity request a limited waiver that expires on the 90th day after the qualifying event. The HVAC board instead requires the entity to apply for an emergency certification, backed by a new bond or bond rider, which likewise runs no more than 90 days (Rule 440-X-3-.08(2)). Either way, the clock runs out on day 90 unless a new qualifier has been approved.

The genuine asymmetry in Alabama qualifier law is not between the HVAC board and the plumbing board. It sits between those two trade boards and the Licensing Board for General Contractors, which governs general contracting under a separate statute. Rule 230-X-1-.36(3)(a) gives a general contracting company 30 days to notify the board that its qualifying party has left and 60 days to qualify a replacement, both longer than either trade board allows. If your Alabama entity runs on one certified HVAC technician or master plumber with no bench, a five day notice window is a business continuity event no matter which trade board regulates you. We cover how to structure around that in Building a Contractor Qualifier Contingency Plan.

The Two Regimes Side by Side

• We found no bond requirement in the plumbing board's Chapter 720-X rules; confirm current requirements with the Board before assuming there is none.
• Both boards carry Class A misdemeanor exposure for unlicensed practice, plus administrative fines: up to $2,000 per violation for HVAC, and a minimum of $500 per violation for plumbing work, or $1,000 for gas fitting work, with the maximum set by state law rather than the boards.

What This Means If You Need an Alabama Qualifier

The practical consequences are specific.

You cannot contract with a qualifier as an outside vendor. Not on the HVAC side, where the statute requires W-2 wages for all earnings. Not on the plumbing side, where the rule requires an active employee and not an independent contractor. Any proposal structured as a monthly fee to a non-employee fails both tests on its face.

You cannot share one qualifier across unrelated companies. The plumbing board's one-entity limit is absolute. The HVAC board's second-entity path requires ownership and financial responsibility in the second entity plus a personal appearance before the Board, granted or denied at its discretion.

You need to plan for the person leaving before they leave. Five days' notice, immediate cessation of contracting, and immediate cessation of work by every other certificate holder in the company is not a scenario you improvise through, on either board.

The state fees are not the constraint. An HVAC certification runs $220 a year plus the $20,000 bond. A plumbing business registration runs $25 a year. Nobody is blocked from operating in Alabama by fees; they are blocked by the requirement that a specific qualified person be genuinely on payroll.

A qualifying agent qualifies the company, meaning the individual is an owner or a full time W-2 employee who actually supervises the work, not a name parked on a certificate. See What Is a Qualifying Agent? for the concept and Hire a Qualifying Agent for how placement works. If you need help structuring compliant coverage in Alabama or other states, our contractor qualifier services are built around the employment or ownership test these boards actually enforce.

How Much Does an Alabama Qualifier Cost?

There is no single number, and any guide that gives you one is guessing. What it takes to have a compliant person in responsible charge or principal master in place depends on the trade and classification, whether you already employ a certified individual, how many entities and states are in scope, the exposure the role carries in your operation, and your timeline. Those variables move the answer substantially; a figure that fits one company is wrong for the next.

What we can tell you is the shape of the cost: a full time employment relationship with a licensed professional who carries real regulatory exposure for your work, plus the board fees above, plus the bond premium on the HVAC side. Talk to us and we will scope it against your actual footprint rather than an average.

Frequently Asked Questions

What is the bond requirement for an Alabama HVAC or refrigeration contractor? New applicants must provide a $20,000 performance bond under Rule 440-X-3-.04(5) before certification, inside the $25,000 cap the Board may set under Code of Ala. § 34-31-30. Proof of bond may be required again at renewal.

Can an Alabama HVAC qualifier be paid on a 1099? No. Code of Alabama § 34-31-18(12) requires that a regularly employed person be an actual employee and not an independent contractor, not be paid as an independent contractor, and receive a Form W-2 for all earnings.

Does Alabama license boiler contractors separately? No. Boiler and pressure vessel installation runs through a Department of Workforce installation permit under the state's Boiler Safety program, not through a contractor license. HVAC-connected boiler work still needs HACR certification.

Can one master plumber qualify two Alabama companies? No. Rule 720-X-12-.02(2) states that no individual shall be registered as the principal master plumber for more than one legal entity regulated by the Board. Rule 720-X-13-.02(2) says the same for gas fitting.

Can one HVAC contractor qualify two companies? Only with Board approval after the individual appears in person and presents evidence of ownership in the second entity, ability to supervise and control it, and financial responsibility for it, plus an additional fee and bond. The Board may refuse at its discretion.

What happens if an Alabama HVAC or plumbing qualifier resigns? Both the qualifier and the company must notify the relevant board within five days, the company must immediately stop entering contracts, and every certificate holder who worked under that qualifier must immediately stop work, until a new qualifier is approved. This rule is nearly identical across the HVAC and plumbing boards.

Is there a grace period if the qualifier dies or becomes incapacitated? Yes, on both boards. The company has 45 days to notify the board with documentation. The plumbing board then allows a limited waiver expiring on the 90th day; the HVAC board instead requires an emergency certification backed by a new bond or bond rider, also capped at 90 days. Resignation, termination, and layoff get no such grace period on either board.

How many hours a week must the HVAC qualifier work? An average of 30 or more hours per week, as a full time employee, per § 34-31-18(12) and Rule 440-X-3-.09(1).
