SECTION 1
HVAC Technician Career FAQ
What Do HVAC Technicians Do?
What HVAC technicians do can vary by position and industry, but generally, they install, maintain, repair and replace HVAC systems. HVAC is an acronym for heating, ventilation and air conditioning. When an “R” is added to the end, it means the tech may also work on refrigeration units.1
Where Do HVAC Technicians Work?
It’s hard to imagine a building that wouldn’t need some kind or heating or cooling system, and these days, most do have one. Consequently, HVAC technicians work just about everywhere:
- Homes
- Schools
- Factories
- Office buildings
- Hospitals1
What Are the Education Requirements for an HVAC Technician?
With the rise in popularity of the Internet of Things (IoT) and smart home technologies, HVAC/R equipment is becoming increasingly complex. As a result, many employers look for workers who’ve completed an HVAC training program at a trade school.1
HVAC certifications and licenses are either required or preferred in some states and industries.1
How Much Do HVAC Technicians Make?
As with job duties, how much an HVAC technician makes can depend on location, industry and several other factors. The annual mean salary for technicians in 2020 in the U.S. was $50,590. This means half of workers earned less and the other half more.1*
HVAC Technician Job Outlook
HVAC technician jobs will see 4% growth through 2029. This is much faster than average.1**

Introduction to Basic HVAC/R Terminology
In order to work in an industry, you’ll need to speak its language. This can be challenging at first in a field filled with acronyms—including its name—and technical terminology.
Learn some of the terms of trade below.
The addition of energy to cause a rise in temperature is considered heating.2 Today, central heating is a common way people warm homes and buildings. These systems typically use hot water, warm air, heat pumps and electric resistance.3
AFUE
Furnaces and boilers are the heating systems found in most homes in the U.S. The efficiency of these systems is measured by the annual fuel utilization efficiency (AFUE). This is an assessment of how efficiently the boiler or furnace converts fuel energy to heat throughout one year.4
HSPF
Heat pumps utilize a reverse refrigeration cycle to warm buildings. They are also a popular choice for heating in the U.S.3 The Heating Seasonal Performance Factor (HSPF) evaluates the amount of energy a heat pump uses during a heating season.5
Oxygen can become depleted inside buildings over time, and harmful particulates can accumulate. Ventilation techniques clean the air. These include bringing fresh air inside and polluted air outside.3
Indoor Air Quality
The air inside a home or business can be up to 2 to 5 times more polluted than the air outside. This is why indoor air quality is so important. Good indoor air quality is achieved when a structure is well ventilated, the temperature and humidity are set at a comfortable level and pollutants are filtered out.6
Air Filters
Air filters remove contaminants from indoor air. There are several different types of air filters, including disposable, washable and high-efficiency. Changing air filters once a month is crucial to ensuring optimal performance.3,7
Indoor space cooling is known as air conditioning. Air conditioning systems typically consist of a compressor, condenser, expansion valve and evaporator. These parts work together, along with refrigerant, to bring hot outdoor air into a building, cool it and pump it throughout the structure or to specific rooms.8
SEER
The Seasonal Energy Efficiency Ratio (SEER) is an assessment of how well an air conditioner cools a building. A SEER rating above 13 indicates that a unit operates at a high efficiency. Depending on the region, the Department of Energy (DOE) requires new A/C units to have a minimum SEER rating of 13 or 14. In 2023, the DOE will enact new minimum energy efficiency standards, requiring a SEER rating of 14 to 15.9,10
Cooling Load
A building’s insulation, construction, and amount of light can all impact the level of heat in a building.11
These factors are calculated to determine how much heat an HVACR system must remove. Collectively they are known as the cooling load.11
While most air conditioning systems are based on the principle of refrigeration, the equipment in this part of the field typically deals with keeping food cold. Temperature sets air conditioning and refrigeration apart: air conditioning applies for spaces above 60°F, and refrigeration for those below 60°F.3
Second Law of Thermodynamics
Integral to the science of refrigeration, this law states that heat naturally travels from warm areas to cold ones. In A/C and refrigeration units, the condenser forces heat to move in the opposite direction, from cold to hot.12
Refrigerant
Refrigerants are chemicals that serve as the working fluid for refrigerators, air conditioners and heat pumps. Their main property is the ability to change from a liquid to a gas at low temperatures. They assist in the heat transfer process.13
