Gilbert, AZ HVAC Training Programs – Schools & Certification

Gilbert, Arizona (AZ) lies within the Sonoran Desert, which has earned a reputation as one of the world’s sunniest regions. Gilbert is regarded as the hottest and driest city in the US. Average temperatures during the summer days exceed 100 degrees, often spiking to 110 and occasionally higher. Summer evenings average about 30 degrees cooler. Winter daytime temperatures cluster around the upper 60s and low 70s, and nighttime temperatures drop to the mid- to low 40s. Freezing temperatures and snowfall are extremely rare in Gilbert. Spring and autumn are warm and short-lived. Rainfall is minimal throughout the year and can result from thunderstorms during the summer months.

Once a small town reliant on agriculture, Gilbert is now a thriving city with a strong and diverse economy. The city continues to maintain high standards of community life and has doubled its population every five years for the past 40 years. Residents are young, averaging under 40 years old, and highly educated.

Economic development has focused on “industries with high concentrations of STEM and STEM-related jobs.” The primary industries now include advanced business services, aerospace and aviation, finance and insurance, high-tech, life sciences, and manufacturing. The Heritage District is home to structures that are on the National Register of Historic Places, luring visitors. The City of the Future initiative is about innovative growth and is also dedicated to “strategically maintaining existing infrastructure over the next few decades” to prevent deterioration.

The desert climate frequently keeps Gilbert residents indoors. Heating, venting, and air conditioning (HVAC) in homes and offices is necessary for relief from the weather extremes. Many of the research facilities, medical and educational institutions, hospitality venues, and retail outlets require the addition of refrigeration (HVAC/R) not only for physical comfort, but also to keep their electronic equipment functioning properly.

Data from the Bureau of Labor Statistics (BLS May 2025, the latest data available as of August 2026) indicates that 8,070 HVAC and HVAC/R mechanics and installers were employed in the Phoenix-Mesa-Chandler, AZ, area, which includes Gilbert. Industry organizations such as the following provide training and support to the technicians and their employers:

American Society of Heating, Refrigerating and Air-Conditioning Engineers
American Subcontractors Association of Arizona
Arizona Construction Trades
Mechanical Trade Contractors of Arizona
Plumbing-Heating-Cooling Contractors Association
Sheet Metal and Air Conditioning Contractors National Association, Arizona Chapter
SMART Local 359

These groups work with government organizations and others in the industry to establish educational and licensing standards. They coordinate safety, performance, promotion, and other guidelines for the HVAC and HVAC/R industry to ensure the safety of technicians and the public.

Occupational Demand for HVAC Technicians in Gilbert, AZ

The demand for professional HVAC and HVAC/R technicians nationwide is increasing, according to BLS (2026) data. They anticipate an 8 percent increase in job openings between 2024 and 2034. That is much faster than the average of 3 percent expected for all occupations in the US. The need for new technicians in Arizona is growing at more than three times the national rate. Projections Central (2026) predicts a 27.3 percent statewide increase in demand for technicians, or 3,140 new positions, between 2024 and 2034.

New commercial and residential construction accounts for most of the job opportunities for HVAC and HVAC/R technicians. The continuing growth and economic prosperity in Gilbert has resulted in additional building efforts to accommodate new businesses and residents, all of which require climate control.

Additionally, the city’s commitment to maintaining existing structures creates demand for new HVAC and HVAC/R equipment to replace, retrofit, or upgrade older systems to meet current safety codes, energy-efficiency goals, and pollution-reduction standards. The increasing dependence on technology makes specialized equipment and systems necessary, especially in the newer “smart” buildings.

Contemporary climate-control equipment and systems continue to increase in complexity and require trained technicians to install, service, and maintain. Technicians who are proficient troubleshooters, skilled in using computers, and understand electronics generally have the best job opportunities.

Occasionally, technicians who specialize in new installations may experience seasonal unemployment. The thriving economy and expansive growth, which includes one data center that requires HVAC, in Gilbert mean that technicians can expect year-round work in the foreseeable future. Technicians who specialize in maintenance and repair services can expect full-time employment, as homeowners and businesses need to keep their equipment in good working order regardless of the economy.

HVAC Apprenticeships in Gilbert, AZ

Although untrained workers could once start as assistants and learn the trade through on-the-job training, those opportunities have dwindled. Most workers now attend classes or participate in an apprenticeship program. Formal training and apprenticeships can open more employment opportunities and provide greater earnings throughout a technician’s career.

Apprenticeships often include 2,000 hours of on-the-job training combined with 144 classroom hours annually for three to five years. The Arizona Department of Economic Security Apprenticeship Office provides information on registered apprenticeships and other resources for workers.

In addition, workers seeking HVAC and HVAC/R apprenticeship programs can find several available through national industry associations such as:

Air Conditioning Contractors of America
Mechanical Contractors Association of America
Plumbing-Heating-Cooling Contractors Association
Refrigeration Service Engineers Society
Sheet Metal Workers International Association

Information as to coursework offered, schedules, and fees is available on their websites.

Accredited HVAC Schools in Gilbert, AZ

Workers who want to increase their employability may choose formal training in accredited diploma, certificate, or degree programs.

HVAC Certification and Licensing in Gilbert, AZ

Technicians who work with refrigerants are required by the U.S. Environmental Protection Agency (EPA) to obtain EPA Section 608 Certification, which includes passing an exam on the safe handling of refrigerants. There are four types of certifications according to the size and kind of systems on which technicians work:

Servicing small appliances – Type I
Servicing or disposing of high-pressure appliances, except small appliances and motor vehicle air conditioning – Type II
Servicing or disposing of low-pressure appliances – Type III
Servicing all types of equipment – Universal or Type IV

Technicians may obtain additional training and certifications from industry organizations to improve their employability. Those organizations also offer Section 608 testing and certification. These include the Refrigeration Service Engineers Society (RSES), North American Technician Excellence (NATE), and HVAC Excellence. Details are available on each website.

The State of Arizona Registrar of Contractors requires that any job exceeding $1,000 for labor and materials must be performed by a licensed contractor. They have three classifications of licensing: residential, commercial, and dual residential/commercial.

HVAC contractors may choose licensure from three types: residential R-39; commercial C-39 or C-58; and dual CR-39 or CR-58. Each license has a specific definition as to the type of work allowed or restricted.

Applicants for all licenses must pass a business management exam and an HVAC exam. They are also required to submit proof of experience, pass a background check, and submit an insurance bond. The amount of the bond is calculated based on the type of license and the volume of work performed.

Initial licensure and renewal of licenses require the payment of a fee, which varies according to the type of license.

Finally, Maricopa County does not require contractors to obtain additional licensing; however, the City of Gilbert requires every business to obtain a business license. Applicants must complete an application that details ownership of the company and pay a fee. Licenses are renewed annually.

As licensing guidelines can change, HVAC technicians are encouraged to ensure that they comply with all requirements before starting a project.
