Changes in the HVAC industry these days happen so fast it’s hard to keep on top of things. As new technologies appear and older ones evolve, the impact on cooling and heating systems is expansive. Everyone in the industry, from manufacturer to distributor, from contractor to technician, knows the importance of staying current, and well ahead of your customers. One of the best ways to do that is by ongoing HVAC training.
HVAC systems in some ways essentially offer the same basic, reliable technology that’s served residential and commercial customers for years. You might say the bells and whistles — the new or improved technology that is making equipment more efficient and improving comfort — are what’s driving the need for continuous training in the 21st century. Here are just a few of the changes most HVAC pros have encountered over the last decade:
So what’s the best way to keep your skills up to date in this rapidly changing industry?
When it comes to training, you might want to explore the several options. These include online training, sending employees to classes at local workforce training institutions, or bringing in trainers to present classes and seminars.
Naturally, in the HVAC industry, you’ll want to give employees the opportunity to update skills in operation and maintenance of gas-fired heating systems and forced air cooling systems. A typical training seminar might consist of a general operation and maintenance class that offers instruction in both heating and air conditioning and refrigeration, although for advanced training, the classes might be specific for heating or air conditioning/refrigeration.
Providing an on-site trainer at your business or nearby will give your team an advantage by allowing them to learn how to use equipment through hands-on demonstration in a comfortable, and perhaps even familiar setting, without the stress and expense of traveling.
A very general HVAC training class might have the following topics:
Electrical components. Technicians should be knowledgeable about electrical wiring for heating and cooling
Electrical safety. Technicians generally need updating on electrical safety testing, including training with test equipment such as an ohmmeter, ammeter, and voltmeter.
Psychrometrics. The study of how air and water vapor interact is crucial for an HVAC technician, who needs to understand principles relating to humidity and evaporation.
Control systems. This training would include information on how the thermostat and on/off controls work.
A class specifically for air conditioning equipment might include instruction on the following:
Air conditioning principles. Technicians should understand the basics of how air conditioning works: how refrigerant cools a building by removing heat as it travels from the outdoor compressor and condenser coils to the indoor evaporator coils and back again.
Handling refrigerant. Only licensed technicians are legally allowed to handle refrigerant. A seminar can teach technicians safe procedures, while providing information on the many new varieties of refrigerant, and why it’s important to avoid mixing them.
Air conditioning Troubleshooting. In today high efficiency A/C it is important to charge a system to the superheat and subcooling that the manufacturer call for. In the NTT HVAC training class we go over A/C troubleshooting techniques.
For heating systems, a seminar would likely include instruction on troubleshooting of burner problems, manifold gas pressure, the heat exchanger, and other parts.
