With hot summers and a booming construction industry, it’s no surprise that the demand for HVAC installers, mechanics, and technicians is reaching a fever pitch in Texas’s largest city. Consequently, Houston is touted as “the most air-conditioned city in the world.”

Not only is there a high-growth employment outlook in Houston’s HVAC industry, but there’s a wealth of professional associations and resources for these invaluable professionals. For example, the Texas Air Conditioning Contractors Association (TACCA) offers a two-day test preparation course for the Texas ACR/HVAC-R contractors exam with lessons in mechanical code, refrigeration, and more. Since only 35 percent of people pass this exam, the TACCA classes and workbooks can be an important resource for qualified HVAC professionals seeking this mandatory credential from the Texas Department of Licensing and Regulation (TDLR).

HVAC mechanics and installers in Houston take on varied responsibilities. The Bureau of Labor Statistics (BLS 2023) reports that these professionals must understand the basic refrigeration cycle; test and repair various system components (e.g., humidifiers, hermetic compressors, heat pumps, ductless splits, water pumps, economizers, motors, intake valves, air ducts, electrical wiring); perform heat load calculations; use blueprints and mechanical drawings; make recommendations to clients for energy efficiency; comply with local and federal legislation; keep detailed customer service records; and maintain active credentialing through the TDLR.

To qualify as an HVAC technician in Houston, candidates typically must be at least 18 years of age, have attended a training or certification program, have a decent driving record, and pass a drug screening. While there are generalist HVAC professionals, others choose to specialize in a type of equipment (e.g., geothermal systems, solar panels) or working environment (e.g., residences, commercial structures).

This guide examines how to become an HVAC or air conditioning worker in Houston, including the employment outlook, salary information, and licensing requirements, as well as a detailed look at the array of accredited HVAC schools in the city.

Occupational Demand for HVAC Professionals in Houston

For HVAC professionals in Houston and nationwide, there’s expected to be an opportunity explosion in the coming years. According to the Bureau of Labor Statistics (BLS 2023), there’s a projected 6 percent increase in openings in this field between 2022 and 2032; notably, this figure is double the average growth anticipated across all occupations (3 percent). Furthermore, the employment climate in Texas may be even more favorable in this line of work. By illustration, Texas employs 31,910 HVAC technicians and installers, the third highest number among all US states (BLS May 2023). Additionally, the Houston-The Woodlands-Sugar Land region boasts the ninth-highest number of HVAC workers among all American metropolitan areas (7,230 employed).

While some of these skilled professionals work usual business hours, other HVAC workers in Houston may be called upon to work evenings, weekends, or holidays, particularly during the high summer season. Also, it’s important to note that HVAC workers incur a higher than average rate of illness and injury than other US occupations (BLS 2023). This is due to the relatively physical nature of the work, which may expose people to burns, muscle strains, and other maladies. That said, with the proper training and safety equipment, these problems can generally be kept to a minimum.

While employment prerequisites vary, many HVAC job postings in the Houston area call for the following:

  • Associate degree or certificate in HVAC technology or a related field
  • At least two years of experience
  • EPA Section 608 and/or NATE, ICE, or other certifications (discussed in section below)
  • Valid driver’s license
  • HVAC technician registration or a contractor’s license through the Texas Department of Licensing and Regulation (TDLR)

There’s no shortage of opportunities for qualified HVAC professionals in Houston. As proof of point, Indeed (April 2024) had 373 relevant job postings in the Houston area, including openings at Village Plumbing and Air, Polk Mechanical Company, Gray Mechanical, to name a few. Monster (April 2024) also had numerous postings at JLL, MHE Mechanic, AGM Management, and Powell Industries. In sum, there’s expected to be a high demand in this field in Houston in years to come.

HVAC Apprenticeships in Houston

HVAC and HVAC/R technicians traditionally began their career as helpers and learned the trade through on-the-job training. It is still possible to do so, but that has become increasingly difficult. Most workers now attend classes or participate in an apprenticeship program. Formal training and apprenticeships open up more employment opportunities. Workers also start at higher wages and potentially earn more throughout their career.

Apprenticeships include specified hours of on-the-job training, usually 2,000 hours, and classroom work, usually 144 hours, annually for three to five years. The Texas Workforce Commission has compiled general instructions for becoming a registered apprentice. Aspiring apprentices should first find an employer willing to train them. The employer should register with the Commission if they have not already done so. The Commission grants funding to registered programs, classroom instruction, and apprentices.

Workers seeking HVAC and HVAC/R apprenticeship programs can find several available through national industry associations such as:

  • Air Conditioning Contractors of America (ACCA)
  • Mechanical Contractors Association of America (MCAA)
  • Plumbing-Heating-Cooling Contractors Association (PHCC)
  • Refrigeration Service Engineers Society (RSES)
  • Sheet Metal Workers International Association (SMWIA)

Details are available on each organization’s website.

HVAC Schools in Houston

Traditionally, the two main accreditation agencies for HVAC training schools are HVAC Excellence and the Partnership for Air-Conditioning, Heating, Refrigeration Accreditation (PAHRA).

HVAC Certification and Licensing in Houston

HVAC training Houston can lead to many different certification options. Eligibility will vary for these certifications, but applicants need to understand that certification is different from a certificate, which may be given as a result of completing an HVAC program, typically a year or less in length. Certification, on the other hand, attests to proven skill sets or knowledge. Some of the certifications that may be available to HVAC school graduates are listed below.

  • HVAC Excellence, founded in 1994, offers certifications for students, experienced technicians, and educators. Its employment-ready certifications may be available to students completing HVAC programs in Houston, but there are also specialty areas, such as in green awareness, that can be pursued.
  • North American Technician Excellence (NATE), founded in 1997, has certification levels that include installation, service, and senior technician. These can be sought in specialty areas such as air conditioning, heat pumps, and hydronics oil.
  • EPA 608 certification is necessary for those wanting to work with refrigerants, which are ozone-depleting substances. There are four categories of this credential which vary by equipment: type I (small appliances), type II (high-pressure refrigerants), type III (low-pressure appliances), type IV (Universal – for technicians who work with all equipment).

Typically, students have to prove their skills through a written exam, but a hands-on test of skills may be required in some cases. Many organizations beyond HVAC schools in Houston offer specific skills training or practice tests to prepare applicants for certification exams. The Esco Institute is one such organization. To learn in-depth about these offerings, please visit the main HVAC certifications page.

Lastly, Texas law requires all HVAC workers to seek registration or licensure through the Texas Department of Licensing and Regulation (TDLR). The first level credential is TDLR’s Air Conditioning and Refrigeration (ACR) Technician Registration, which is required for anyone who wants to install, repair, or maintain HVAC systems while working under a licensed HVAC contractor. There is also an ACR certification which is optional and requires passing an exam. The application fee to become a Registered ACR Technician is $20, and for Certified ACR Techs it’s $35.
Lastly, an Air Conditioning and Refrigeration Contractor License is necessary for those seeking to advertise their HVAC services in Houston and beyond. To qualify for a TDLR contractor license, candidates must pass a comprehensive examination after submitting the following:

  • Proof of 48 months of practical experience under the supervision of a licensed contractor in the previous 72 months
  • Application fee

There are various types of HVAC contractor licenses available in Texas which vary by type and size of system. There are licenses available for specialists in Environmental Air Conditioning and Commercial Refrigeration/Process Heating & Cooling, as well as a combined license for people with abilities in both of these areas. Additionally there are Class A and Class B licenses; the former allows the licensee to work with any size unit, and the latter allows the licensee to service cooling systems of 25 tons and under and heating systems of 1.5 million BTUs/hour and under.

Finally, Texas has licensing reciprocity with South Carolina and Georgia, and Texas HVAC contractors may provide service work in those states after seeking a letter of good standing from the TDLR. To learn more about how to obtain these credentials, check out the full details on the TDLR website.

As licensing regulations are always subject to change, HVAC professionals are encouraged to confirm that they comply with current state and local guidelines before starting a project.
