What You Need to Do to Get Licensed as an HVAC Technician in New Mexico

New Mexico requires HVAC technicians to hold a license issued by the Regulation and Licensing Department (RLD). The path depends on whether you want to work as a refrigeration technician, air conditioning technician, or combination refrigeration and air conditioning technician. Each category has its own experience requirements, exam, and fees. You cannot legally install, repair, or maintain air conditioning or refrigeration systems in New Mexico without one.

The process takes months because you must complete on-the-job training hours before you can sit for the exam. Most people work as apprentices or helpers under a licensed technician while they accumulate those hours. Once you have enough hours logged, you pay a fee, pass a written exam, and receive your license from the RLD.

Key Takeaways

  • New Mexico requires 8,000 hours of on-the-job training for air conditioning technicians and 10,000 hours for combination refrigeration and air conditioning technicians before you can test.
  • You must work under a licensed HVAC contractor or technician to log your training hours, and your employer must verify them on official RLD forms.
  • The written exam covers safety codes, refrigerant handling, electrical basics, and system repair — you study from the RLD's published exam outline.
  • The exam fee is $75, and the license fee is $150 for a four-year license; you renew every four years with continuing education.
  • You can find the RLD's HVAC licensing rules in the New Mexico Administrative Code (NMAC) 14.7.2, which lists all requirements and forms.

Training Hours and Work Experience Requirements

The number of hours you must work depends on the license type you want. An air conditioning technician license requires 8,000 hours of hands-on work. A refrigeration technician license also requires 8,000 hours. A combination refrigeration and air conditioning technician license requires 10,000 hours. These hours must be completed within five years of your exam process.

All hours must be logged under a licensed HVAC contractor or licensed technician in New Mexico. You cannot count work done in another state or work done without supervision. Your employer signs off on your hours using the RLD's official Experience Verification Form, which you submit with your exam process. The form must show the dates you worked, the hours per week, and the types of work you performed — installation, repair, maintenance, or a combination.

Many people work as apprentices or helpers while logging hours. Some employers offer formal apprenticeship programs through trade schools or unions, which combine classroom instruction with on-the-job training. Others hire helpers directly and track hours informally. Either way, you need written verification from your employer before the RLD will let you test.

How to Find an Employer and Start Logging Hours

You do not need a license to work as an HVAC helper or apprentice. Contact HVAC contractors in your area — look in the phone directory, online business listings, or ask at local trade schools — and ask if they hire helpers or apprentices. Many contractors are willing to hire people with no experience because they can train them on the job. Be clear that you are working toward a license and need your hours documented.

Once hired, ask your employer for the RLD's Experience Verification Form at the start of your employment. Keep a personal log of your hours and the types of work you do each day. At the end of each month or quarter, have your supervisor sign off on the hours. This prevents disputes later about how many hours you actually worked. Some employers use time clocks or digital tracking; others rely on handwritten records. Either way, the RLD form is the official record.

If you work for a contractor who is not licensed in New Mexico, your hours may not count. Before you accept a job, confirm that your employer holds a current HVAC contractor license from the RLD. You can check this on the RLD's website under the Contractor License Search tool.

Preparing for and Taking the Written Exam

Once you have completed your required hours, you can explore to take the written exam. The RLD publishes an Exam Outline for each license type on its website. The outline lists the topics covered: refrigerant safety and handling, electrical basics, system components and operation, troubleshooting, installation practices, and New Mexico building codes. Study from this outline — it tells you exactly what to expect.

The exam is multiple-choice and covers practical knowledge, not theory alone. You are tested on things like how to detect a refrigerant leak, how to size a system for a building, how to wire a thermostat, and what the state code says about venting. Many people study using HVAC textbooks, online practice exams, or prep courses offered by trade schools. The RLD does not offer study materials, but trade schools and testing companies sell them.

You take the exam at a testing center approved by the RLD. The exam takes about three hours. You must score at least 70 percent to pass. If you fail, you can retake it after 30 days. There is no limit on how many times you can test, but you pay the exam fee each time.

Submitting Your process and Exam Fee

To explore for the exam, submit the following to the RLD's HVAC Licensing Bureau: a completed process for HVAC License form, your Experience Verification Form signed by your employer, a copy of your government-issued ID, and a check or money order for the exam fee of $75. The RLD's website lists the current mailing address and any online submission options.

The RLD processes applications in the order received. Processing typically takes two to four weeks. Once approved, you receive an exam authorization letter with a date and location. You must take the exam within 90 days of receiving the letter. If you do not test within that window, you have to reapply and pay the fee again.

Keep copies of everything you submit. If the RLD rejects your process because your hours do not meet the requirement or your employer's signature is missing, you need to know what was wrong so you can fix it and resubmit.

Paying the License Fee and Receiving Your License

After you pass the exam, the RLD issues your license. Before you can use it, you must pay the license fee of $150. This covers a four-year license period. You pay this fee only once, when you first receive your license. The RLD sends you a bill or invoice; you mail a check or pay online if that option is available.

Once the RLD receives your payment, you receive your official license card and a certificate. You are now legally permitted to work as an HVAC technician in New Mexico. Some employers require you to display your license in your work vehicle or at the job site, so keep it accessible.

Your license is valid for four years from the date of issue. You do not have to renew it every year — only once every four years. When renewal time approaches, the RLD sends you a renewal notice with instructions and the renewal fee amount.

License Renewal and Continuing Education

To renew your license every four years, you must complete 16 hours of continuing education from an RLD-approved provider. The education must cover topics relevant to HVAC work — refrigerant handling, safety codes, new equipment, or system design. You can take these courses online, in person, or through your employer's training program, as long as the provider is approved by the RLD.

The RLD publishes a list of approved continuing education providers on its website. Some are community colleges, trade schools, or professional associations. Others are online platforms. Courses typically cost $50 to $200 and take a few days to a few weeks to complete, depending on whether you attend in person or online.

You must complete your 16 hours before your license expires. Submit proof of completion — usually a certificate from the course provider — with your renewal process and fee. If you do not renew on time, your license lapses and you cannot legally work until you renew it.

Where to Find RLD Forms and Contact Information

All RLD forms and requirements are available on the New Mexico Regulation and Licensing Department website under the HVAC Licensing section. You can read the process for HVAC License, Experience Verification Form, and Exam Outline as PDF files. The website also lists the current exam fee, license fee, and renewal fee.

If you have questions about your process or the process, contact the RLD's HVAC Licensing Bureau by phone or email. The contact information is on the website. Staff can tell you whether your hours meet the requirement, whether your employer is licensed, and what to do if your process is rejected. Response times vary, but most inquiries are answered within one to two weeks.

You can also check the status of your process online if the RLD offers that service. The website may have a license lookup tool where you can search by name to see whether a license is active, expired, or pending.

Frequently Asked Questions

Can I count hours I worked in another state toward my New Mexico license?

No. New Mexico requires all 8,000 or 10,000 hours to be completed under a licensed contractor or technician in New Mexico. Work done in other states does not count. If you are moving to New Mexico from another state where you were licensed, you may be able to transfer your license through reciprocity, but that is a separate process — contact the RLD to ask whether your state's license is recognized.

What if my employer goes out of business before I finish my hours?

You can switch to a different employer and continue logging hours. Have your new employer sign the Experience Verification Form for the hours they supervise, and have your old employer sign for the hours they supervised. Submit both forms with your process. The RLD accepts hours from multiple employers as long as each one is licensed and signs off on the hours they witnessed.

Do I need a high school diploma or GED to get an HVAC license?

New Mexico does not require a high school diploma or GED for an HVAC license. You need only the required work hours and a passing exam score. However, some employers or apprenticeship programs may require a diploma or GED as a condition of hire, so check with individual employers.

How long does it take to get a license from start to finish?

It typically takes 18 months to three years. You need 8,000 to 10,000 hours of work, which at 40 hours per week takes two to five years depending on how many hours you work per week. Once you have your hours, the process and exam process takes another two to four months. Many people work part-time or irregular hours, which extends the timeline.

Can I work as an HVAC technician while I am still logging hours?

No. Until you pass the exam and receive your license, you can only work as a helper or apprentice under a licensed technician. You cannot sign off on work, pull permits, or work independently. Once licensed, you can work independently or supervise helpers and apprentices.
