It’s a welcome sight when the HVAC technician’s truck arrives on a hot summer’s day after your air conditioning has lost its cool. Or when your heater has had a breakdown in the bleak midwinter. Do you want to be that HVAC hero behind the wheel?  

If you enjoy working with your hands and are good at problem-solving, a career in heating, ventilation, air conditioning, and refrigeration (HVACR) is a rewarding and prosperous way to earn a living. You are in the driver’s seat—it’s not a desk job.  

In this article, we’ll look at what it takes to become an HVAC technician and what it means to be HVAC Excellence accredited on a national level. We’ll also review some of the best technician training programs in the United States.  

What Does an HVACR Tech Do?  

HVAC Tech In Training

The US Bureau of Labor Statistics projects a positive job outlook for HVACR mechanics and installers with solid 5% growth from 2021 through 2031.  

So, what, exactly, does an HVACR career entail?  


Keeping a household warm uses more energy and costs more money than any other system in a home, making up about 29% of your utility bill.  

The 2020 United States Census discovered that 47.5% of Americans used gas to heat their homes, 39.8% used electricity, and 0.2% used solar energy.  

The different types of heating equipment that Americans choose to control their indoor climates—like furnaces, boilers, and heat pumps—all need maintenance by HVAC specialists.  


Four basic ventilation systems can maintain the indoor air quality of your house. Each system works best in different parts of the country, depending on the climate of the region. And each system requires installation and maintenance by a ventilation specialist.  

Exhaust system – works by depressurizing your home. Best suited to cold climates.  

Supply system – uses a fan to pressurize your home, forcing outside air into the building. Works best in hot or mixed climates.  

Balanced system – usually uses two fans and two duct systems. Supplies fresh air to rooms where people spend the most time. Appropriate for all climates.  

Energy recovery system – can recover 70 to 80% of energy in exiting air and deliver it to incoming air. Requires more maintenance than other systems. Most cost-effective in climates with extreme winters or summers where fuel costs are high.  

Air conditioning  

According to the US Energy Information Administration (EIA), nearly 90% of American households use air conditioning. Two-thirds rely on a central AC system to cool their homes.  

Air conditioning lets communities flourish year-round in hotter states like Arizona and Florida. Work opportunities for HVAC technicians are abundant.  

With AC almost universal in the United States, it may be surprising to learn that the job outlook for a technician is not as optimistic in Europe—fewer than 10% of European homes have air conditioning.  


The “R” in HVACR applies to industrial refrigeration—not the maintenance of a refrigerator in your home. That falls under appliance repair.  

In commercial HVACR systems, industrial refrigeration is essential for industries such as food and beverage, pharmaceuticals, and petrochemicals.  

While the core principles of refrigeration are the same as air conditioning, the stakes are different. If your AC doesn’t work, it affects your comfort on a human level and doesn’t need an emergency repair.  

If a refrigeration system goes down, the chance of losing hundreds of thousands of dollars worth of products is at risk. Refrigeration technicians are on call nights and weekends. Maintenance of refrigeration systems is not generally an entry-level job. The work is demanding and requires patience and resilience.

What Education Do You Need to Become an HVAC Technician?  

HVAC Trainee Making Repairs

In general, you need at least a high school diploma or GED to be an HVAC technician. It’s not a job for someone who wants to punch a clock—it requires flexibility and grit.  

Because HVACR systems are rapidly becoming more technically complex, an applicant with post-secondary education at a tech school is a big plus. Those who have completed apprenticeships are also in demand. In some states and localities, technicians need licenses.  

Technical schools and institutes offer programs that prepare students for a specific trade or career. They can span less than two years for entry-level positions to up to four years for more advanced learning.  

Upon completion, graduates earn a degree, diploma, or certificate. Training at a program that is HVAC Excellence accredited can give you an edge.  

What Is HVAC Excellence Accreditation?  

HVAC Excellence is a not-for-profit organization based in Mount Prospect, Illinois, that was founded in 1994. Back then, heating and cooling technology was rapidly advancing, and technicians needed to stay sharp. The non-profit improved the technical skills of the HVACR workforce by setting quality standards.  

Around the same time, school systems throughout the US worried that their tech programs were not keeping pace with the real world.  

The Tennessee Board of Regents shared this concern. They ordered that an independent organization conduct a peer review of their HVAC training programs.  

What they discovered was even more disturbing—there was no national accreditation agency for the HVACR industry.  

They finally encountered HVAC Excellence, which met their benchmarks. The two organizations worked together to establish a set of standards. In 1999, HVAC Excellence launched the industry’s first national accrediting body.  

Today, the ESCO Institute manages HVAC Excellence. Its mission is to ensure that the HVACR educational system stays at the top of its game.
