Who Needs a License in Oregon?
Any individual, partnership, or business that performs compensated construction work improving real property, including HVAC system installation, repair, or maintenance, must comply with HVAC license requirements in Oregon. There is no project value minimum that exempts you from licensing, if you are paid for your HVAC work, you must be licensed by the CCB.
According to Oregon law, the scope of required licensing covers all forms of heating, ventilation, air conditioning, and refrigeration work. The Limited Maintenance Specialty Contractor HVAC/R (LHR) license specifically covers limited maintenance and minor repair, while higher classifications allow broader scopes. The required license type depends on the project: residential, commercial, general contractor, or specialty contractor, and what type of work you intend to perform. Subcontractors and employees each have distinct rules: subcontractors must be independently licensed for the specific endorsement relevant to their work, while employees working directly for a licensed contractor do not need a separate license but must be listed if required for the classification.
There are no general exemptions for owner-builders or handymen with respect to HVAC work. This means that even small residential jobs require a licensed contractor if compensation is involved. In short, the HVAC license requirements in Oregon apply across all job sizes, and every person accepting payment for this work must hold the designated CCB license and bond in their name or business.
Oregon HVAC License Types
Oregon recognizes several classifications for contractors working in the HVAC field. The most directly relevant is the Limited Maintenance Specialty Contractor HVAC/R (LHR), issued by the CCB in partnership with the Building Codes Division (BCD). This license is limited to certain types of HVAC/R servicing and maintenance, not full installations, and is defined by the minor-label scope available from BCD.
Apart from the LHR, contractors can apply for residential or commercial endorsements at both the general and specialty levels. The most common types that apply to HVAC work include:
Residential Specialty Contractor (RSC): Permits specialty residential work, including specific trade areas like HVAC installation and service.
Residential General Contractor (RGC): Allows all forms of construction, supervision, and contracting on residential projects, including HVAC.
Commercial Specialty Contractor Level 1 (CSC1) and Level 2 (CSC2): Level 1 covers complex/commercial projects and requires more experience, while Level 2 covers smaller or simpler commercial jobs.
Commercial General Contractor Level 1 (CGC1) and Level 2 (CGC2): Level 1 is for all types of commercial construction including HVAC, Level 2 is more limited in scope.
Each license class has unique experience, bond, and scope of work requirements. For HVAC-only maintenance or certain minor repair services, the LHR endorsement may be sufficient. Larger projects or those involving installation, replacement, or broader construction require the relevant specialty or general contractor endorsement.
Importantly, only one Responsible Managing Individual (RMI) can be listed per license, and a person cannot hold multiple active licenses for the same classification as the RMI. The correct license and endorsement must always match the project scope, failure to comply with these HVAC license requirements in Oregon may result in administrative penalties.
How to Meet HVAC License Requirements in Oregon
To meet the HVAC license requirements in Oregon, you must successfully complete each application step and supply documentation to the CCB. Each stage ensures you meet the necessary business, legal, and technical standards.
Step 1: Confirm Eligibility and Experience
Ensure that the applicant (the RMI) is at least 18 years old and meets experience requirements for the desired endorsement.
Document trade experience as required. For most specialty or general contractor licenses (not LHR), Level 1 classifications require around eight years, Level 2 require about four years. Use the Verification of Qualifying Person’s Experience form if needed.
Step 2: Education, Exam, and Application
Register for and complete the required sixteen-hour pre-license education course approved by the CCB. Provider lists are on the board website.
After completing pre-license education, take the contractor exam administered by PSI testing service. If you passed the NASCLA Accredited Commercial exam, submit your transcript and complete the Oregon exam module only.
Apply online through the CCB portal for a new license; attach your passing test score, completed application, surety bond, and proof of general liability insurance. For LHR, submit the separate Contractor/Business License Application to the BCD, designate a qualified supervisor, and list all required employees.
Step 3: Submit Bond, Insurance, and Complete Background Check
File your required surety bond, submit proof of general liability insurance, and provide Workers’ Compensation insurance documentation if you have employees.
The Responsible Managing Individual (RMI) must complete a background check after submitting your application as instructed by the CCB.
Step 4: Processing, Forms, and Timing
Applications submitted online process in approximately four weeks. Paper applications may take six to eight weeks. You can request a Paper Application Request form by emailing the CCB if you cannot apply online. Always use only official CCB or BCD forms.
Keep copies of all documentation submitted and review the correct forms for business structure or endorsement change as required for the HVAC license requirements in Oregon.
Application Requirements
Meeting the HVAC license requirements in Oregon involves several application requirements, each designed to ensure legal operation and consumer protection.
Experience and Age
The Responsible Managing Individual must be at least 18 years old. They will need to document trade experience on the Verification of Qualifying Person’s Experience form. For most specialty or general contractor licenses (not LHR), Level 1 classifications require around eight years, Level 2 require about four years. Review the board’s endorsement chart and contractor guide for exact requirements for your intended license.
Bond and Insurance
Oregon requires that all licensed HVAC contractors carry a surety bond, with amounts that depend on the license and endorsement (see Fees section for current values). You must submit an original bond for your application. In addition, proof of General Liability insurance is mandatory. Minimum amounts vary by endorsement and are detailed in the Guide to Becoming a Licensed Contractor. If you hire employees, you must also carry valid Workers’ Compensation insurance and provide documentation.
Background Check and Certifications
The Responsible Managing Individual listed on the license must complete a background check after the application is submitted. The CCB conducts this directly and provides instructions. However, as of the latest official guidance, there is no fingerprinting or federal (EPA 608) certification requirement for state-level HVAC licensure through the CCB or BCD for most licenses.
Exams
Successful completion of the required exam is a key part of HVAC license requirements in Oregon. The board mandates a business- and law-focused test for all contractor applicants, including those seeking HVAC endorsements.
Exam Details
The standard exam is the NASCLA Oregon edition, which covers business management, construction law, and project management topics relevant to contractors. The exam is administered by PSI, a national testing service contracted by the CCB. You must first complete an approved sixteen-hour pre-license training program, then register for the exam and pay the required fee.
There is no separate HVAC-specific trade exam. The LHR and other HVAC work scopes are handled via license endorsement and documented experience, not a separate technical examination. For those who have previously passed the NASCLA Accredited Commercial exam in another state, it is possible to submit an official transcript and complete only the Oregon-specific business/law exam as a substitute for pre-license education.
Exam Format and Retakes
The exam format is managed by PSI and typically provides an immediate pass/fail result. Specifics on number of questions and passing score are not published by the CCB, so you should confirm at the time of scheduling. If you do not pass, you can reschedule, pay the fee again, and retest as many times as needed.
For further exam details, including instructions and fees, see the official CCB license exam page.

Renewal and Continuing Education for HVAC License Requirements in Oregon
Renewal and continuing education are core elements of HVAC license requirements in Oregon for nearly all contractor classifications. Ensuring timely renewal and completing required education helps maintain good standing with the board.
Renewal Cycle and Deadlines
CCB contractor licenses, including HVAC classifications, must be renewed every two years. The board mails renewal reminders about eight weeks before your expiration date. A renewal costs $400, and there is no published late penalty, but expired licenses may not be used to bid or work. If your license expires for more than two years, you must reapply and retake pre-license training and the contractor exam.
Continuing Education (CE) Requirements
Residential contractor license holders must complete continuing education in each license period. If you have been licensed for fewer than six years, you must complete thirteen hours of approved coursework (plus three hours of laws and business practices, for sixteen total), every cycle. Contractors licensed at least six years require five hours of additional coursework (with three hours of laws/regs, for eight total).
Acceptable CE courses include topics in building codes, safety, business law, construction trade skills, energy efficiency, and environmental hazards. Approved course providers are listed by the CCB, and the hours must be tracked and reported during renewal. Lead-based paint renovator initial or refresher classes, or Oregon OSHA consultations, may count towards the total if they meet board approval.
Specialty Licenses: Holders of Limited Maintenance Specialty Contractor HVAC/R (LHR) licenses are exempt from CE requirements, though they must still renew every two years. Commercial Level 1 and 2 contractors must complete between 16 and 80 CE hours based on the number of key employees.
In short, always review your current CE status before submitting for renewal to avoid possible delays or penalties. If CE requirements change, the board will publish updates on its Continuing Education page.
Reciprocity
Oregon does not have formal reciprocity agreements for HVAC contractor licenses with any other state as of 2026. All applicants must complete the standard process for HVAC license requirements in Oregon, including pre-license education and passing the Oregon-specific exam (or NASCLA/Oregon module combination, if eligible).
Because no endorsements or license transfers are currently accepted from other states, you must meet every Oregon CCB requirement from the beginning, regardless of your status elsewhere. For confirmation, see the CCB website and review their contractor licensing FAQs.
