Denver, CO HVAC Trade Schools

Connect With HVAC Schools

Denver, Colorado (CO) has long been known as the Mile High City due to its elevation. Four distinct seasons define the weather, but local geography affects conditions in some neighborhoods. In general, the summers are hot, with temps in the high 90s. Temperatures in the dry winters frequently dip below freezing and residents often cope with up to five feet of snow.

“The Metro Denver region’s economy is strong and growing,” according to city officials in a recent report, and they point to the “strength and diversity” of the economy as an indication of continued growth. They make note of several large-scale construction projects underway or planned, including renovating the airport. Millions of square feet of new office and industrial space will keep construction activity strong. Denver’s economic base has grown from agriculture and mining to industries that rely on technology, including telecommunications, information, healthcare, and professional and scientific services.

Denverites rely on heating, venting, and air conditioning (HVAC) for comfort in their homes and workplaces. The city is home to a variety of museums, historical sites, and entertainment venues—all of which often require commercial-scale refrigeration (HVAC/R) services as well.

The Bureau of Labor Statistics (BLS May 2017) reports that 3,540 HVAC mechanics and installers were employed in the Denver-Aurora-Lakewood are. State and local chapters of industry organizations that provide training and support to the technicians include:

  • Associated General Contractors of Colorado (AGC)
  • Colorado Association of Mechanical and Plumbing Contractors (CAMPC)
  • Colorado Contractors Association (CCA)
  • Plumbing-Heating-Cooling Contractors Association of Colorado (PHCC)
  • Rocky Mountain Chapter of the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE)
  • Sheet Metal Workers Local 9
  • UA Pipefitters Local 208

Additional support and resources for workers and their employers are available from national industry associations that include:

  • Air Conditioning Contractors of America (ACCA)
  • American Society of Mechanical Engineers (ASME)
  • Mechanical Contractors Association of America (MCAA)
  • Refrigeration Service Engineers Society (RSES)
  • Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA)

These organizations coordinate with others in the industry and with government organizations to establish educational and licensing standards. They serve all aspects of the HVAC and HVAC/R industries, including safety, performance, and promotion.

Read on to discover the salary prospects and occupations outlook for HVAC professionals in Denver, including information about accredited training programs and credentialing.

Occupational Demand for HVAC Technicians in Denver, CO

Demand for HVAC technicians is growing nationwide. According to the BLS (2018), openings for technicians are expected to increase 15 percent nationwide between 2016 and 2026. That is much faster than the average of 7 percent projected for all occupations in the U.S. Furthermore, the demand for technicians in Colorado is growing at more than twice the national average. Projections Central predicted a 38.3 percent statewide increase in HVAC jobs for the same decade.

Several factors contribute to the growth of the HVAC industry. The primary factor is the increasing sophistication of climate control systems and the need to replace, retrofit, or upgrade older systems. Also, industries that depend on technology, such as those in Denver, frequently require specialized systems to keep electronic equipment in operation. Additionally, the contemporary emphasis on energy efficiency and reducing pollution is another factor leading to the installation of new equipment and systems.

The BLS (2018) reported that HVAC and HVAC/R mechanics and installers nationally receive a median salary of $47,080 annually. Technicians in the Denver-Aurora-Lakewood area receive an annual median salary of $57,940.

Accredited HVAC Schools in Denver, CO

HVAC technicians traditionally began their career as helpers and learned the trade through on-the-job training. These days, aspiring HVAC professionals now attend classes or participate in an apprenticeship program.

Apprenticeships include around 2,000 hours of hands-on job training and 144 classroom hours annually for three to five years. Build Colorado provides information on trade apprenticeships through a Workforce Development Program sponsored by the Associated General Contractors of America and the Colorado Contractors Association. The site lists available apprenticeships, training sponsors, and schools offering the required classroom work.

The Colorado Skilled Trades Education Program (STEP) provides a union-based pre-apprenticeship opportunity in several trades, including HVAC. Enrollees learn basic skills such as CPR and first aid; financial responsibility; construction math; blueprint reading; industry awareness; and receive basic hands-on training in their chosen trade. The classes are free and are available during the day and evenings.

The Denver Plumbers Local 3, the Pipefitters Local 208, and the Sheet Metal Workers Local 9 all participate in STEP. They also offer full-length apprenticeship programs through their joint apprentice training centers (JATC) in the Denver area.

Details are available on their websites.

Other aspiring HVAC workers in Denver enroll in accredited degree or diploma programs. Accreditation is a process by which an independent agency evaluates the quality of an educational institution’s program. When choosing a school, it is essential to determine if it is accredited and which organization granted accreditation.

Two industry organizations evaluate HVAC programs: the Partnership for Air-Conditioning, Heating, Refrigeration Accreditation (PAHRA), which has awarded accreditation to Front Range Community College in Fort Collins, CO, and HVAC Excellence, which has accredited Pikes Peak Community College in Colorado Springs, CO.

HVAC Certification & Licensing in Denver, CO

The U.S. Environmental Protection Agency (EPA) requires technicians who work with refrigerants to obtain EPA Section 608 Certification. Certification requires passing an exam on the safe handling of refrigerants. The four certifications are:

  • Type 1: small appliances
  • Type II: high-pressure refrigerants
  • Type III: low-pressure refrigerants
  • Technicians who will be working on all types of equipment are required to obtain Universal HVAC certification.

Practice exams are available.

Technicians may obtain additional HVAC training and certifications from industry organizations. These include, but aren’t limited to, the Refrigeration Service Engineers Society (RSES), North American Technician Excellence (NATE), and HVAC Excellence. These and others offer Section 608 testing and certification.

As a final note, the Colorado Department of Regulatory Agencies (DORA) does not require licensing of HVAC technicians or contractors, but there are some requirements for contractors, particularly in Denver.

The City of Denver requires contractors to obtain licenses. A self-employed technician is generally regarded as a contractor. Plumbing and electrical contractors must first obtain state contractor licenses. All other mechanical contractors, including HVAC and HVAC/R, must obtain supervisor certificates or employ a person who has a certificate. They have several categories of certificates, including: HVAC journeyman, HVAC Class A supervisor or Class B supervisor, HVAC residential only; hot water supervisor; refrigeration Class A or Class B supervisor, refrigeration journeyman, and refrigeration operator.

Each category includes clear definitions as to the scope of work that may be performed. For example, an HVAC journeyman contractor may not work on water heaters that exceed 100 Mbtu input or wiring that exceeds 48 volts.

Applicants must pass the relevant International Code Council (ICC) exam, as well as submit notarized proof of work experience and an affidavit of lawful presence in the U.S. Each category has specific work experience requirements. For example, the HVAC Class B supervisor certificate requires six years of residential experience, four of which should be as a journeyman mechanic and two of which must be as a designer, draftsman, or supervisor. Fees are $40 for a journeyman certificate and $60 for a supervisor certificate.

Once the certificate is received, the business may then apply for a contractor’s license. Applicants must submit document their legal business status, such as articles of incorporation or trade name registration if a sole proprietor, and provide proof of their identity. Contractor licenses must be renewed every three years. License fees are $250.
