HVAC Contractor License in Idaho: Requirements, Qualifier, Bond and Exams

Yes — statewide.

Idaho has licensed HVAC work since July 1, 2004: the statute makes it unlawful for any person or firm, copartnership, association or corporation to engage in the business, trade, practice or work of heating, ventilation and air conditioning in this state unless the person, or the responsible person representing the firm, has passed the examination and holds a state certificate of competency.

The business-level rungs are the contractor certificates — the HVAC contractor certificate of competency, issued by the Idaho HVAC Board through DOPL, and the HVAC specialty contractor certificate for specialty work.

The statute's exemptions include homeowners working on their own single-family or duplex home, and employers that regularly employ HVAC journeymen for maintenance on their own premises.

The Idaho HVAC Board issues the certificates of competency, administered by the Division of Occupational and Professional Licenses (DOPL), which also runs the state's online licensing services.

The statute sets four classifications of competency in HVAC: apprentice, journeyman, HVAC contractor and HVAC specialty contractor, plus specialty apprentice and specialty journeyman classes for areas such as gas piping and hearth appliances.

For a contracting business the relevant classes are the last two: the HVAC contractor certificate and the HVAC specialty contractor certificate, which the HVAC rules govern through one rule section — it requires the same Board examination and compliance bond of each.

Everything else on this page — the exam, the bond, the 24-month cycle — attaches to whichever of those two your business holds.

Idaho's statute runs the license through a person.

A firm may not engage in HVAC work unless the responsible person representing it has passed the examination and holds a state certificate of competency, so the qualifier in Idaho is that responsible person — the individual who passes the examination and is issued the certificate of competency your business contracts under.

On experience, the HVAC rules set no separate experience requirement for the HVAC contractor certificate: the contractor and specialty contractor section of the rules asks for a passing examination and a compliance bond, and no hours or years.

That is a real difference from Idaho's plumbing rules, which require a plumbing contractor to hold a journeyman plumber certificate first — the state's experience ladder sits at the journeyman certificate, not the contractor certificate.

When you recruit that person, you can confirm the certificate they hold in DOPL's eDOPL online services, under Search for a License.

An applicant for the contractor certificate must successfully pass an examination designated by the Board, and Idaho's HVAC and contractor exams are delivered by PSI.

Our research records the exam requirement but not the content outline, so we cannot split it for you into a trade paper and a separate business-and-law paper — what DOPL's HVAC program page does say is that the Contractors' Business and Law Reference Manual may be brought into the exam in a binder, with pre-highlighting allowed and no writing during the exam, and it passes along PSI's advice to register online for the fastest and most convenient scheduling.

Confirm the current exam outline and candidate rules with DOPL and PSI before you book.

One instrument is on the face of the rule: a compliance bond in the amount of $2,000, which the applicant must provide for the certificate period.

On insurance, our research did not find an insurance minimum for HVAC contractors in the Idaho HVAC statute or the administrative rules we read.

We also did not check Idaho's separate general contractor registration (Title 54, Chapter 52), so we cannot say whether it adds registration or insurance duties for HVAC contractors — ask DOPL what it requires of your business before you apply rather than assuming the bond is the whole of it.

The statute sets the cycle: certificates of competency expire 24 calendar months from the date of issue, renewal can be requested up to 60 days before expiration, and an expired certificate can be revived within 1 year with a $35 revival fee.

The fee itself is the gap: we found no certificate fee amount in the statute or rules as read, so price the certificate with DOPL before you budget.

Two related costs are on the books: HVAC permits start at a $100 base residential fee plus per-appliance charges — $30 for the first furnace, heat pump or air conditioner — and on continuing education, our research did not find a CE hour figure in the current HVAC rules (IDAPA 24.39.70), though the statute lets the board set continuing education by rule, so confirm any CE with DOPL before your renewal date.

Our research did not find reciprocity provisions for HVAC contractors in the Idaho HVAC statute or the administrative rules we read, and the research did not check Idaho's separate general contractor registration (Title 54, Chapter 52), so we cannot say whether such a rule covers HVAC contractors.

This page therefore cannot tell you that Idaho honors another state's HVAC contractor credential, and it cannot tell you that it does not.

If you hold a contractor license from another state and want it counted toward an Idaho certificate, put the question to the HVAC Board through DOPL before you plan your application.

The requirement the statute keeps in force runs through a person: a firm may not engage in HVAC work unless the responsible person representing it has passed the examination and holds a state certificate of competency.

What our research does not cover is the departure itself — nothing we read sets a replacement step, a deadline or a grace period for a departing HVAC qualifier — so confirm with DOPL what it expects when the responsible person changes, and what it requires of a replacement, before your qualifier gives notice.

The nearest Idaho rule we found is on the plumbing side: a plumbing contractor certificate holder may represent only one person or business at a time and must immediately notify DOPL in writing if that representation ends.

The HVAC rules we read do not carry that clause.
