Hawaii · HVAC licensing · official-source guide
Hawaii's Contractors License Board (DCCA) licenses HVAC work through two specialty classifications: C-52 Ventilating and Air Conditioning and C-40 Refrigeration. Applicants need 4 years of supervisory trade experience, must pass PSI's two-part exam, and carry liability insurance of at least $100,000/$300,000 bodily injury and $50,000 property damage. Licenses renew biennially; EPA Section 608 refrigerant certification is a separate federal requirement.

Hawaii regulates heating, ventilation, air conditioning and refrigeration work at the state level only. The agency is the Contractors License Board, which sits inside the Professional and Vocational Licensing Division of the Department of Commerce and Consumer Affairs (DCCA). The board's authority comes from Hawaii Revised Statutes (HRS) chapter 444, Contractors, and its detailed rules sit in Hawaii Administrative Rules (HAR) chapter 16-77. Hawaii does not use a single HVAC license. Instead it issues specialty contractor licenses by classification, and the two that cover this trade are separate from each other. C-52 is the Ventilating and Air Conditioning contractor classification. C-40 is the Refrigeration contractor classification. Under HRS 444-9, no person may act, assume to act, or advertise as a specialty contractor in either classification without a license issued by the board. There is no city or county HVAC license layered on top of the state license anywhere in Hawaii. Oahu, Hawaii, Maui and Kauai counties do not run their own contractor licensing programs for mechanical trades. What each county does require is a building or mechanical permit before HVAC equipment is installed, altered or replaced, and state law ties issuance of that permit back to the state contractor license, covered later on this page. A C-52 or C-40 license covers the contracting business, not the individual technician handling refrigerant. A separate federal certification under EPA Section 608 of the Clean Air Act applies to any individual, licensed or not, who services, maintains, repairs or disposes of equipment that could release refrigerant. That EPA layer sits on top of the state license and is explained in its own section below. This page covers the contracting-business license: who must hold C-52 or C-40, what the board requires to issue and renew each one, what it costs, what insurance and bond the board requires, the penalties for skipping the license, and how a customer can check whether a company holds a current one.
HAR 16-77-28 lists every specialty classification the Contractors License Board issues, and HAR 16-77 Exhibit A spells out what each one covers. Two classifications carry the HVAC and refrigeration trade. C-52, Ventilating and air conditioning contractor, is defined as the work to fabricate, assemble and install warm-air heating and air cooling systems, including heating and cooling solar systems, complete ventilating systems and complete air conditioning systems. The classification's scope reaches piping, controls other than electrical, instrumentation, building automation and energy management connected to those systems, plus the trenching, backfilling, patching and surface restoration needed to install them. It also covers installing the thermal and acoustical insulation needed to hold heat or sound inside those systems, and it specifically includes installing heat pumps related to the air conditioning system. C-40, Refrigeration contractor, is defined as the work to assemble and install devices, machinery and units, including temperature insulation units, ducts, blowers, registers, humidity and thermostatic controls, for the control of air temperature below fifty degrees Fahrenheit in refrigerators, refrigerator rooms and insulated refrigerator spaces, and to construct walk-in refrigerator boxes. A related classification, C-40a, covers installing prefabricated refrigerator panels only. The fifty-degree line in C-40 is the practical boundary between the two classifications. Comfort heating, ventilating and air conditioning work sits under C-52. Commercial refrigeration, walk-in coolers and freezer boxes sit under C-40. A company that installs residential split systems and heat pumps needs C-52. A company that builds and services restaurant walk-in coolers needs C-40. A company that does both needs both classifications, since HAR 16-77-33 limits a specialty contractor to the classification or classifications actually held. Neither classification is bundled automatically with a general license. HAR 16-77-32 lists the narrower classifications that come free with an A general engineering or B general building license, and C-52 and C-40 are not on either list.
Three kinds of HVAC and refrigeration businesses operate in Hawaii, and each maps to a different licensing answer. A company that installs, alters or services warm-air heating, ventilating or air conditioning systems, including heat pumps tied to an air conditioning system, needs a C-52 license. That covers most residential and light commercial HVAC contractors doing split-system, ducted, ductless and heat pump work. A company that installs or services commercial refrigeration equipment, walk-in coolers, freezer rooms or insulated refrigerator spaces below fifty degrees Fahrenheit needs a C-40 license. This is the classification for restaurant, grocery and cold-storage refrigeration work rather than comfort cooling. A company doing both lines of work needs both C-52 and C-40. HRS 444-8(b) lets a licensee apply for and hold more than one classification, and a licensee who already holds one classification pays the application fee for the additional one but not a second license fee. HAR 16-77-34 gives a narrow exception for incidental and supplemental work. A specialty contractor may take and execute a contract involving two or more crafts if the work outside the contractor's own classification is incidental and supplemental to the licensed craft. That does not turn a C-52 contractor into a licensed electrician or plumber; it only covers minor overlap tied to the HVAC scope itself, such as the trenching and patching that C-52 already lists as part of its own definition. A general A or B contractor who wants to offer HVAC work directly, rather than subcontracting it, has to add C-52 or C-40 as an additional classification the same way a specialty contractor would. General licenses do not carry HVAC or refrigeration authority by default under HAR 16-77-32. Homeowners and building owners who do their own work on their own property may qualify for the owner-builder exemption in HRS 444-9.1, but that exemption is limited to structures for personal use, not offered for sale within a year, and registered with the county as required by that section.
Hawaii licenses the contracting business through a qualified individual rather than the paperwork of the business alone. The board's application system reflects that with three separate application types: Contractor Entity, Contractor Sole Owner, and Contractor Responsible Managing Employee (RME). HAR 16-77-3 defines a contracting entity as a corporation, partnership, joint venture, limited liability company or other entity that has met the financial integrity requirements to engage in the contracting business and that has in its employ a responsible managing employee. The same rule defines the RME as the individual who is a bona fide employee of the contracting entity, and who qualifies the entity for a license in the classifications the individual holds. In plain terms, the entity cannot get a C-52 or C-40 license unless a real employee of that entity personally meets the experience, exam and financial integrity requirements for that classification. HRS 444-11.1 and HAR 16-77-69 through 16-77-76 govern how the license and RME relationship works day to day. The license belongs to the entity, is nontransferable, and is directly managed through the RME. HAR 16-77-71 allows a principal RME and subordinate RMEs for larger operations, and HAR 16-77-72 allows one RME to qualify more than one contracting entity under conditions the board sets. A sole proprietor applies individually and personally meets the same experience and examination requirements, without needing a separate RME, since the individual is both owner and qualifier. HAR 16-77-87 requires every contracting entity, other than an RME applying alone, to maintain a permanent physical place of business within Hawaii where the entity can be served notice and legal process, and where the license is prominently displayed. A post office box does not satisfy this. HAR 16-77-89 allows an out-of-state licensee to use an office, such as an attorney's office, as that place of business, provided someone there can accept service and handle correspondence, and HAR 16-77-88 requires the board be notified of any address change within ten business days.

HAR 16-77-18 sets the experience bar for every individual applicant or RME seeking a Hawaii contractor license, including C-52 and C-40. The applicant must have had, within the ten years immediately before filing the application, not less than four years of supervisory experience as a foreman, supervising employee or contractor in the particular classification sought. Three conditions inside that rule matter for HVAC and refrigeration applicants specifically. The four years must be supervisory rather than purely hands-on installer time. The experience must be in the classification applied for, so HVAC installation experience supports a C-52 application and commercial refrigeration experience supports a C-40 application, rather than one automatically covering the other. And the experience has to fall inside the ten years immediately preceding the application, so decades-old supervisory work can fall outside the window. HAR 16-77-18(b) gives the board discretion to accept self-employed or unlicensed experience as qualifying, which matters for technicians who ran their own unlicensed HVAC business or supervised installs out of state before applying in Hawaii. HAR 16-77-18(c) requires a contracting entity to qualify through an RME who independently meets this same four-year requirement. HAR 16-77-19 allows the board to approve certain technical or business administration training as a substitute for part of the experience requirement, but caps that credit at one year regardless of how much training the applicant completed. HAR 16-77-20 separately allows the board to accept any reasonably equivalent knowledge, training or experience in place of the specific experience requirement, but only if the board investigates and makes a detailed finding to that effect; this is discretionary, not automatic. Hawaii does not require a specific trade school credential, an apprenticeship certificate, or a minimum number of classroom hours as a precondition to applying for C-52 or C-40. The requirement in the rules is supervisory experience in the classification, documented on the chronological history of projects form the board requires with every individual or RME application.
Every applicant for a Hawaii contractor license, including C-52 and C-40, sits a two-part written exam under HAR chapter 16-77. HAR 16-77-39, Examination part I, tests the applicant's general knowledge of the building, safety, health, labor and lien laws of the state and the basic administrative principles of the contracting business. HAR 16-77-40, Examination part II, tests the applicant's specialized knowledge in the particular classification sought, meaning the C-52 or C-40 trade content. Since January 2023 the board has contracted the exam out to PSI Services, LLC. Under the board's published examination process, an applicant's paperwork must first be approved by the board before the applicant may register for the test. Once approved, the applicant receives an examination approval letter listing which exam or exams the applicant is eligible to take, along with instructions for registering directly with PSI. The board asks applicants to allow up to twenty-four hours after the approval letter is issued before registering. There is a hard deadline on passing. The board's rules require applicants to pass the examination within six months of becoming eligible to take it; anyone who does not pass within that six-month window must file a new application and start over. Hawaii Revised Statutes 436B-9 backs this with a one-year abandonment rule: an application is destroyed if the licensing process is not completed within one year of filing. HAR 16-77-41 provides the only route around the exam, and it is narrow. An examination is not required when the applicant previously qualified by written examination within the last four years, or was last licensed in good standing or inactive status within the last four years, provided the new application is for the same classification the applicant previously qualified in. This is a lookback for people re-entering the same Hawaii classification, not a waiver for out-of-state credentials. Applications, fees and supporting documents must reach the board's office by the first Tuesday of the month two months before the scheduled board meeting date, under the board's published filing deadline.
Hawaii's contractor license fees for C-52 and C-40 are set in HAR 16-53-17, Fees Relating to Boards and Commissions, and they are the same fee schedule the board applies to every classification, including HVAC and refrigeration. The base application fee is $50. An application fee for a bond waiver or entity conversion is $25. Examination fees are set separately by agreement between the board and PSI, the testing service, rather than fixed in the rule. Original license fees are $260 for a contracting entity and $260 for a responsible managing employee. Because Hawaii licenses on a two-year biennium, the amount actually due depends on where in the two-year cycle the license is issued. A contracting entity licensed in the first year of the biennium pays $355, which is the $260 original fee plus half of the $190 biennial renewal fee; a contracting entity licensed in the second year of the biennium pays $260. An RME licensed in the first year of the biennium pays $290, and in the second year pays $260. On top of the license fee, a new applicant pays a one-time recovery fund fee of $150 for a contracting entity, and an education fund fee of $10. These fees fund the contractors recovery fund and the contractors education fund described in the next section, and both are refunded to the applicant if the board does not issue the license. At renewal, every two years, a contracting entity pays a biennial renewal fee of $190 and an RME pays $60, plus a $5 education fund fee and a $10 recovery fund fee each renewal cycle. A licensee who misses the renewal deadline and later restores a forfeited license pays a $50 penalty fee in addition to the biennial renewal fee itself. All fees are payable to the Department of Commerce and Consumer Affairs, and dishonoring a check on first deposit under HAR 16-77-12 counts as a failure to meet the fee requirement.
Two special funds sit behind every Hawaii contractor license, funded by the fees described above, and HRS 444-26 spells out how the recovery fund actually works for HVAC and refrigeration customers. A homeowner or condominium or cooperative unit owner who is injured by the act, representation, transaction or conduct of a licensed contractor, in violation of chapter 444 or the board's rules, may recover from the contractors recovery fund by court order. Recovery is capped at $12,500 per contract, regardless of how many people were injured under that one contract, and is limited to actual damages plus court costs and reasonable attorney fees. The fund does not pay out for a contractor whose license was suspended, revoked, forfeited, terminated or inactive at the time the customer signed the contract, which is one more reason checking license status before signing matters. HRS 444-26(c) is what actually fills the fund: every new applicant pays a $150 recovery fund fee in addition to the original license fee, along with a separate education fund fee. HRS 444-27 lets the board assess every contractor up to $500 a year if the fund balance drops below $250,000, and failing to pay that assessment within sixty days forfeits the contractor's license. The education fund works differently. HAR 16-77-12 sets a $10 contractors education fund fee on every application, and HAR 16-77-54 sets a $5 education fund fee at each biennial renewal. That money supports licensing and education administration rather than paying consumer claims directly. For an HVAC or refrigeration customer, the practical takeaway is that the $12,500 recovery cap applies per contract, not per violation, and only protects work on a private residence contracted with a currently active licensee. Commercial refrigeration and HVAC contracts for businesses fall outside the definition of an injured person under HRS 444-26(b), which is limited to owners and lessees contracting for their own private residences.

Hawaii sets specific dollar minimums for the liability insurance every C-52 and C-40 licensee must carry, and those minimums are enforced at both application and every renewal. HAR 16-77-10 requires every applicant to submit a certificate of insurance showing full policy coverage for liability and property damage insurance with minimum limits of $100,000 per person and $300,000 per occurrence for bodily injury liability, and $50,000 per occurrence for property damage liability. HAR 16-77-55, which governs renewal, requires proof that the same limits, $100,000 per person and $300,000 per occurrence for bodily injury and $50,000 per occurrence for property damage, have been continuously maintained. Workers' compensation insurance is required separately. HRS 444-11(a)(8) and HAR 16-77-10 require every applicant to submit proof of workers' compensation insurance under HRS chapter 386, unless the applicant is authorized to act as a self-insurer or is excluded from chapter 386's requirements, in which case the applicant signs a statement claiming that exclusion. A surety bond is not automatically required of every C-52 or C-40 licensee. HRS 444-16.5 gives the board discretion to require a specialty contractor to post a bond of not less than $5,000, taking into account the licensee's financial condition and experience, and the same $5,000 minimum applies if the board requires a bond of a general contractor. When the board does impose a bond, it is conditioned on paying wages owed to the contractor's employees and on the honest conduct of the licensee's business, and it gives an injured party a right of action against the bond. HRS 444-11.1 makes the consequence of letting any of this lapse automatic: failure to maintain workers' compensation insurance, liability insurance or a required bond in full force causes the license to forfeit automatically as of the date that coverage lapsed. A licensee has sixty days to restore the license by proving continuous coverage; missing that window forfeits all fees paid and forces a new application from scratch.
Hawaii contractor licenses, including C-52 and C-40, run on a two-year cycle rather than an annual one. HAR 16-77-49 requires the board to send a notice of renewal to every licensee before August 15 of each even-numbered year, and HAR 16-77-50 requires licensees to complete and submit their renewal by September 30 of that same even-numbered year. HAR 16-77-55 lists what a licensee must prove to renew: continued compliance with HRS 444-11, 444-11.1 and 444-17 and this chapter, plus a current state tax clearance or proof of a payment arrangement, a disclosure of any liens or unpaid judgments from contracting work, continuous workers' compensation insurance, continuous liability and property damage insurance at the $100,000 per person, $300,000 per occurrence, and $50,000 property damage minimums, and proof that any board-imposed bond is current. The board's own published renewal checklist for firms and sole proprietors lists the same items, plus renewal of the designated RME, since a contracting entity's license cannot renew if its RME's license does not also renew. Notably absent from HAR 16-77-55 or the board's renewal materials is any continuing education hour requirement. Hawaii's contractor renewal is built entirely around financial integrity, insurance, bonding and tax compliance rather than continuing education credits, unlike many other licensed trades. HAR 16-77-51 allows a forfeited license to be restored within sixty days of the expiration date, subject to meeting restoration requirements. The board's own site repeats this directly: failure to restore a forfeited license within sixty days after the expiration date terminates the license, and the person must apply as a brand new applicant and meet the licensing requirements current at that later date, including retaking the exam. HAR 16-77-54 adds that late renewal carries the biennial renewal fee plus a penalty fee. HAR 16-77-56 allows a licensee to place a license on inactive status instead of renewing it for active use, which avoids the insurance and bond maintenance burden while keeping the license on record rather than letting it forfeit.
Hawaii's contractor licensing rules do not contain a reciprocity agreement with any other state for C-52 or C-40. An HVAC or refrigeration contractor licensed elsewhere files the same application, documents the same four years of classification-specific supervisory experience under HAR 16-77-18, and sits the same PSI examination as a first-time applicant with no prior license anywhere. The only exam relief in the rules, HAR 16-77-41, does not reach across state lines. It waives the exam only for an applicant who previously passed a Hawaii written exam within the last four years, or who was last licensed in Hawaii in good standing or inactive status within the last four years, and only for the same classification previously held. A contractor who has never held a Hawaii license gets no benefit from this rule no matter how long they have held a C-52 equivalent license in another state. What does carry across state lines is underlying experience rather than the license itself. HAR 16-77-18 requires four years of supervisory experience in the classification within the last ten years, and does not require that experience to have been earned in Hawaii. HAR 16-77-18(b) lets the board accept self-employed or out-of-state unlicensed supervisory experience at its discretion, and HAR 16-77-20 lets the board accept reasonably equivalent knowledge, training or experience in place of the specific requirement if it makes a detailed finding to that effect. Mainland and other-state HVAC contractors who plan to work in Hawaii still have to satisfy the Hawaii-specific parts of licensure directly: passing the Hawaii exam, meeting the $100,000/$300,000/$50,000 insurance minimums, and maintaining a permanent Hawaii place of business under HAR 16-77-87, or an equivalent office arrangement for out-of-state licensees under HAR 16-77-89. There is a narrow emergency-license path under HRS 444-10.6 during a declared state of emergency or disaster, open to contractors already licensed in another state with similar requirements, but it is temporary and tied to the declared emergency rather than an ordinary reciprocity route.
HRS 444-9 is the core rule: no person may act, assume to act, or advertise as a specialty contractor, including under classification C-52 or C-40, without a license previously obtained under chapter 444. Violating it carries several layers of penalty rather than one flat fine. HRS 444-23(c) sets the base civil fine for violating section 444-9 at $2,500 or forty percent of the total contract price, whichever is greater, for a first offense; $3,500 or forty percent of the contract price, whichever is greater, for a second offense; and $5,000 or forty percent of the contract price, whichever is greater, for any offense after that. Tools, implements, documents, materials or other property used in the unlicensed activity are also subject to forfeiture to the department under HRS 444-23.5, separate from the fine itself. HRS 444-10.5 gives DCCA investigators authority to issue a citation directly to anyone found acting as a contractor without a license, ordering the person to cease and desist and assessing the civil penalties set in 444-23. If the cited person does not request a hearing within twenty days, the citation becomes a final order automatically. Violating a resulting cease-and-desist order carries its own fine of not less than $10,000 per offense, and each day of continued violation counts as a separate offense. Two enhancement provisions raise the stakes further. HRS 444-10.7 allows a fine of up to $10,000, imprisonment of up to one year, or both, when an unlicensed contracting violation is committed against a person sixty-five years of age or older. HRS 444-10.6(e) allows the same up-to-$10,000 fine and up-to-one-year imprisonment when unlicensed repair work follows a declared natural disaster. Advertising while unlicensed carries a separate exposure under HRS 444-9.2, covered in the next section, and HRS 444-9.3 makes it a misdemeanor to knowingly help an unlicensed HVAC or refrigeration contractor evade the licensing law, including allowing one's own license to be used by someone else.
Sourcesfiles.hawaii.gov
Hawaii treats advertising without a valid license as its own violation, separate from performing unlicensed work, and it applies to a C-52 or C-40 contractor the same as any other classification. HRS 444-9.2(a) makes it a misdemeanor for any person, including a person otherwise exempt from chapter 444, to advertise as a contractor, with or without limiting qualifications, unless that person holds a valid license for the goods and services advertised. The statute defines advertising broadly: it covers signs on a building, vehicle or structure, listings in a newspaper, magazine or directory under a heading that includes the word contractor, and broadcast commercials, in addition to obvious print and online ads. HRS 444-9.2(b) sets the display requirement itself: a licensed contractor may advertise in print or broadcast media only if the advertisement includes the contractor's applicable and current license number, and the contractor provides proof of that number's validity to the publisher or producer of the ad. A publisher or broadcaster is required to refuse to run an ad or listing for a contractor who does not comply with this. HAR 16-77-83 repeats the same requirement at the rule level and extends the definition of media to the internet: a contracting entity advertising through any media must be identified by the name under which it is licensed, or its filed trade name, plus its license number. HRS 444-9.2(c) adds a consumer-facing enforcement tool: once a court or the board finds a contractor advertised in violation of 444-9 or 444-9.2(a), the telephone utility serving that contractor is required to disconnect the phone number used in the advertisement. Separately, HAR 16-77-87 requires every contracting entity to display its license prominently at its permanent Hawaii place of business, not merely in advertising. Together these rules mean a C-52 or C-40 contractor's license number has to appear on print and broadcast ads, directory and internet listings, and be posted at the business address, with no exception for a contractor who simply forgot to renew.
The Contractors License Board's own site directs consumers to a free online tool for checking whether an HVAC or refrigeration contractor's license is current before signing a contract. From the board's page at cca.hawaii.gov, the Verify a Professional and Check a License links lead to the state's public license search portal at mypvl.dcca.hawaii.gov/public-license-search, where a name or license number search returns the license classification held, whether C-52, C-40 or both, the license status, and whether required insurance and bond filings are current. Checking this before signing matters for reasons beyond simple compliance. HRS 444-26(a) specifically excludes recovery from the contractors recovery fund for anyone injured by a contractor whose license was suspended, revoked, forfeited, terminated or inactive at the time the contract was signed. A customer who verifies an active C-52 or C-40 license before work begins preserves the ability to use that fund later if something goes wrong; a customer who skips that step and later discovers the license had lapsed may have no recovery fund claim at all. HAR 16-77-87's requirement that every contracting entity display its license prominently at its place of business gives customers a second, low-tech way to confirm licensure directly at a contractor's office, in addition to the online search. Since the license number must also appear on any print, broadcast, directory or internet advertisement under HRS 444-9.2 and HAR 16-77-83, a customer can cross-check the number shown in an ad against the same license record on the state portal. The board's site separately maintains a Business Check tool for researching a company's registration and complaint history with DCCA, which complements the license lookup but is a distinct search covering business registration rather than the professional license itself.

Hawaii's four counties, City and County of Honolulu, Hawaii County, Maui County and Kauai County, do not issue their own HVAC contractor licenses, but each requires a building or mechanical permit before HVAC equipment is installed or altered, and state law ties that permit process directly back to the state contractor license. HRS 444-9.1(a) requires that every county or other local subdivision of the state that requires a permit as a condition of construction, alteration, improvement, demolition or repair of a building or structure must also require, before issuing that permit, a statement from the applicant that the applicant and all specialty contractors working on the project, including any C-52 or C-40 contractor, are licensed under chapter 444, giving their license numbers and confirming the licenses are in full force. An applicant claiming an exemption, such as an owner-builder, must instead state the basis for that exemption. This requirement applies uniformly across all four counties because it is set in state statute rather than county ordinance. On Oahu, the largest of Hawaii's counties by population, the City and County of Honolulu's Department of Planning and Permitting (DPP) administers building permits, including mechanical and HVAC work, under the Revised Ordinances of Honolulu. DPP's HNL Build online portal is where contractors and owner-builders submit permit applications, and DPP enforces the same license-number statement HRS 444-9.1 requires statewide before issuing a permit for HVAC installation or replacement work. Because the license-and-permit link comes from state law rather than local ordinance, an HVAC or refrigeration contractor with an active C-52 or C-40 license and license number in hand satisfies the licensing side of a Honolulu, Hilo, Wailuku or Lihue building permit application the same way; what differs county to county is permit fee schedules, inspection scheduling and portal software, not whether a state license is required at all.
A Hawaii C-52 or C-40 contractor license covers the state's requirement to operate as an HVAC or refrigeration contracting business. It does not by itself satisfy a separate federal requirement that applies to the individual technician handling refrigerant, regardless of what state license their employer holds. Under Section 608 of the federal Clean Air Act, EPA regulations at 40 CFR Part 82, Subpart F require that technicians who maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere be certified. According to EPA, a technician is defined as anyone who attaches or detaches hoses and gauges to measure pressure in an appliance, adds or removes refrigerant from an appliance, or otherwise performs any activity that violates the integrity of a motor vehicle air conditioner-like appliance or a small appliance, other than disposal. Apprentices are exempt from certification only if they are closely and continually supervised by a certified technician. EPA has created four certification types, each tied to specific equipment: Type I covers servicing small appliances; Type II covers servicing or disposing of high- or very high-pressure appliances other than small appliances and motor vehicle air conditioners; Type III covers servicing or disposing of low-pressure appliances; and Universal certification covers all of the above and requires passing the Type I, II and III tests plus a proctored core exam. According to EPA, technicians must pass an EPA-approved test administered by an EPA-approved certifying organization, and Section 608 certification credentials do not expire once earned. For a Hawaii C-52 or C-40 contracting business, this means every technician in the field, not just the RME who qualified the license, needs the EPA 608 certification matching the equipment that technician actually services. A company can hold a fully current C-52 license and still be exposed to federal enforcement if it sends an uncertified technician to open a sealed refrigerant system. The state license and the federal certification are independent requirements that both apply at the same time.

No. Hawaii's Contractors License Board issues two separate specialty classifications that cover this trade: C-52, Ventilating and air conditioning contractor, and C-40, Refrigeration contractor. A company doing both comfort HVAC and commercial refrigeration work needs both classifications, not one combined HVAC license.
C-52 covers warm-air heating, ventilating and air conditioning systems, including heat pumps tied to air conditioning. C-40 covers refrigeration equipment that controls air temperature below fifty degrees Fahrenheit, such as walk-in coolers and freezer rooms. Comfort cooling falls under C-52; commercial refrigeration falls under C-40.
HAR 16-77-18 requires at least four years of supervisory experience as a foreman, supervising employee or contractor in the specific classification, C-52 or C-40, within the ten years immediately before you apply. The board may credit self-employed or unlicensed experience at its discretion.
PSI Services, LLC has administered the exam since January 2023. After the board approves your application, PSI sends registration instructions, and you must pass both the general business and law exam and the trade-specific exam within six months of becoming eligible.
The application fee is $50. The original license fee is $260 for the entity and $260 for the responsible managing employee, plus a one-time $150 recovery fund fee and $10 education fund fee for the entity. Biennial renewal is $190 for the entity and $60 for the RME, plus $5 and $10 fund fees.
HAR 16-77-10 and 16-77-55 require liability and property damage insurance with minimum limits of $100,000 per person and $300,000 per occurrence for bodily injury, and $50,000 per occurrence for property damage, maintained continuously at application and every renewal. Workers' compensation insurance is also required unless the contractor is exempt.
Not automatically. HRS 444-16.5 gives the Contractors License Board discretion to require a specialty contractor to post a bond of not less than $5,000, based on the applicant's financial condition and experience. When required, the license forfeits automatically if the bond lapses.
Every two years. The board sends renewal notices before August 15 of each even-numbered year, and renewal is due by September 30 of that year. There is no continuing education hour requirement; renewal instead requires proof of current insurance, bond and tax clearance.
No. Hawaii's rules contain no reciprocity agreement with other states. An out-of-state C-52 or C-40 equivalent license holder files the same application, documents the same four years of classification-specific experience, and passes the same Hawaii exam as a first-time applicant.
HRS 444-23(c) fines unlicensed contracting at $2,500 or 40 percent of the contract price for a first offense, rising to $5,000 or 40 percent for later offenses, plus possible forfeiture of tools and materials. Violating a cease-and-desist order adds a fine of at least $10,000 per day.
Yes. HRS 444-9.2 and HAR 16-77-83 require any contractor advertising in print, broadcast, directory or internet media to include their current license number. Advertising as a contractor without a valid license is a misdemeanor, and publishers must refuse noncompliant ads.
No. The C-52 or C-40 state license and the federal EPA Section 608 technician certification are separate requirements. Under 40 CFR Part 82, Subpart F, any technician who services, maintains or disposes of refrigerant-containing equipment must hold the matching EPA certification, regardless of the company's state license.
