Not Cool! – Fixing The HVAC Skills-Gap

HVAC technology has progressed immensely in the last 10 years. Innovations like high efficiency smart systems have driven the industry, and customers to demand much higher levels of convenience with installed systems that can be controlled in a more modular style, via smart phones or set to change automatically based on environmental factors.  Expansions in warehouse sectors and housing have also created a higher demand for HVAC installation and services. While most people feel the effects of HVAC in their homes and workplaces, many may not realize how essential the technology is to other industries such as Food, Healthcare and Data Centers.

Time Added To Your HVAC Repairs

Where Are The Workers?

In spite of the modernization of HVAC products, the workforce hasn’t necessarily followed along. In conjunction with a large swath of older technicians reaching retirement age,  according to,; ‘the number of unfilled HVAC technician jobs is about 80,000 or 39% of technicians currently employed’. In addition, there’s a net technician loss of about 8% or 20,000 per year. This loss is exacerbated by a distinct lack of talent being attracted to the industry –“a scant 6 percent of high school students hope to have a future career in the skilled trades – defined as plumbers, carpenters, electricians, heating, ventilation or air conditioning installers, or repair people” .  When asked for the reasons for their responses, students said they didn’t think skilled trades were ‘high-tech’ enough and because they believe there is a ‘lack of opportunity’.

And what is the impact of the lack of workers for everyone else? There are pervasive ways this labor shortfall affects the public; the amount of time customers need to wait for maintenance and emergency call-outs has been extended, and also in the rising cost of services which are up between 8% to 12%. So what can be done to increase the number of highly-skilled workers choosing trades?

What Can Be Done?

Educators should consider that, in addition to public demand, the current White House administration is determined to pass the American Jobs Plan, which has a huge focus on skilled labor. If passed, Mr. Biden’s bill will inject $590 billion of funding into in Domestic Manufacturing, Research & Development, and Job Training Initiatives, via high schools

Women In HVAC Jobsand technical colleges. Whether the bill passes or not, its discussion may herald a change in perception of trade-based career paths – which can provide high-school graduates a much cheaper and quicker route into paid employment than the widely encouraged college track.  In addition, the number of women interested in skills-based work has started to trend upward, while just 1.4 percent of HVAC mechanics and installers are women, according to the U.S. Bureau of Labor Statistics. Given the stigma, and lack of training available there is little incentive for women to pursue careers in HVAC at the moment.

The Solutions Are Out There

Schools and learning institutions can offer inclusive and comprehensive technical training to prepare students for the HVAC technician positions available today and into the future.


HVAC On The Roof

Todays’ HVAC technicians must be able to install, service, troubleshoot, and repair a wide variety of different types of components, including furnaces, air conditioners, boilers, heat pumps, refrigerators, coolers, freezers, humidifying units, and air filtration systems.

These packed training programs not only benefit new workers, but also existing technicians who should be flexible and open to developing their skills.

The Amatrol family of technical training solutions, including training systems and learning aids from DAC Worldwide and Bayport Technical, offers a wide variety of products to take your maintenance training needs to the next level and ensure your maintenance efforts yield a solid return on investment.


Amatrol’s HVAC training systems offer high-quality, comprehensive interactive multimedia eLearning curriculum guides students and workers through hands-on skill development with physical trainers packed with real industrial HVAC components.

Amatrol’s Thermal Science Learning System (T7081) teaches learners the basic principles of modern thermal systems, such as HVAC, geothermal, refrigeration, and steam systems.


Once learners have mastered the basics, Amatrol offers more advanced thermal training systems in a variety of areas, including:

Amatrol also offers four HVAC training systems designed to bridge the HVAC skills gap and prepare future HVAC technicians to succeed in the jobs of the present and future:

Residential Heat Pump Troubleshooting Learning System (T7100)

Amatrol’s Residential Heat Pump Troubleshooting Learning System (T7100) teaches critical HVAC skills related to residential HVAC systems that use a heat pump and traditional ducting. Learners will work with real industrial HVAC equipment, such as: a heat pump condenser, heat pump air handler, Wi-Fi-enabled thermostat, and ducting. The T7100 was also designed to include transparent housings, pipes, and ducting with LED illumination that allows learners to see inside the system. Fault Pro HVAC

The T7100’s interactive multimedia eLearning curriculum covers a wide variety of fundamental residential heat pump topics, including: thermostat operation, pressure and temperature measurements, component tests, and system troubleshooting. The curriculum also focuses on the development of critical hands-on skills, including: operating a heat pump in heating and cooling modes, testing a thermostatic expansion valve, and troubleshooting insufficient cooling.

Residential Mini-Split Heat Pump Learning System (T7130)

Amatrol’s Residential Mini-Split Heat Pump Learning System (T7130) focuses on residential ductless (“mini-split”) HVAC systems. Learners using the T7130 will work with real industrial HVAC equipment, such as: a heat pump condenser, evaporator unit, thermostat, panel-mounted gauges, and condensate pump. The T7130 also features transparent housings and pipes with LED illumination that allow learners to see inside the system. Fault Pro Heat Pump

The T7130’s eLearning curriculum covers fundamental residential mini-split system topics, including: remote controller adjustments, heating and cooling modes, LED indicators, communication between units, and system troubleshooting.
