Common Electrical Terms You Need to Know

The beautiful thing about beginning your career as an HVAC technician is that you don’t need any previous experience or knowledge. At the Training Center for Heating and Air Conditioning, our classes cover the absolute basics, so students of all knowledge levels can be on equal footing. All you need is a good work ethic and a willingness to learn.

That being said, for anybody considering education and training in heating and cooling can certainly benefit from familiarizing themselves with some important elements of working in HVAC. 

One of the most important things to understand during your HVAC training is the language and terminology. HVAC installation and repair incorporates many common electrical terms that you may have heard before or run into during previous science classes in school. Understanding these terms is crucial for HVAC technicians and beginning your education with knowledge of them can get you started off on the right foot.

Here are some common electrical terms HVAC technicians need to be familiar with and what they mean. Each of these terms relates to different materials and parts of a heating or cooling system that relate to the transfer of electricity. 

Conductor

An electrical conductor is any kind of material that allows electricity to flow easily through it with little to no resistance. Certain metals like copper, aluminum, silver, and gold are all terrific conductors of electricity. This is why many of the wires used in HVAC equipment are made of these materials. This is also a great reason why practicing extreme safety precautions when working with live wires.

Resistor

An electrical resistor is any material or component in the electrical circuit that resists the flow of electricity, limiting the amount of electricity that passes through them at any given time. Resistors are important because without them limiting electrical flow to motors, coils, lights, and heat elements, these components would become overloaded with electricity and more quickly burn out or overload causing a loss of efficiency and creating potential hazards.

Capacitor

An electrical capacitor stores electricity for short periods. Many HVAC systems have dual capacitors, a start capacitor and a run capacitor. The start capacitor provides the electrical power needed to get the compressor or fan motor of the heating and cooling system started up. The run capacitor, on the other hand, in turn, supplies the compressor or motor the energy it requires to keep them running.

Insulator

An electrical insulator is a material or component of a heating and cooling system that does not allow electricity to flow through it. Wires and thermal pipes in an HVAC system are equipped with insulating coverings to prevent the loss of energy and heat so the unit can run more efficiently.

Now don’t think that knowing the meaning of these common electrical terms makes you an expert. There are still plenty of other important terms you’ll need to know as you continue your HVAC education. However, for folks looking to start their journey without much past experience, understanding these terms can get you off to a good start.
