HVAC Educational Guide With Updated Resources

Choosing a career in any field available on the market becomes a struggle, especially now that it overflows with potential possibilities and offers advertised by many and misunderstood by many more.

Becoming a HVAC engineer is no exception. Hypothetical risks accompanying any idea should be the first and foremost priority to take care of and eliminate on the road to success. The only proper way to do it is by acknowledging their existence and understanding the main aspects associated with your choice.

Putting aside all the secondhand information available online for any probable candidate, there is a variety of accurate resources to help guide you through the process. We composed a genuine resource guide for anyone considering a career as a HVAC mechanic.

HVAC System Breakdown

What exactly is HVAC?

It would be a good idea to understand the abbreviation itself before progressing onto more complex issues regarding training, certifications, or salaries.

Briefly, HVAC stands short for Heating, Ventilation, Air Conditioning – therefore, all the significant features related to temperature management in majority of residential households and commercial buildings all over the country.


  • This element is mainly used during cooler period of the year
  • There are three types of heating systems available:
    • Forced air heating system, by far the most recognizable, uses furnace as a medium to heat the air. The ductworks and vents disperse generated heat throughout the house.
    • Radiant heating systems produce heat via boilers or heating stoves, which then use electric heating coils or hot water tubing to distribute heat throughout the house.
    • Geothermal heating generates heat through heat exchanger. Where does the heat come from? In fact, it is derived from the very constant temperature of the ground.


A ventilator helps establish a normal breathing for a person with respiratory problems. For a literary work, this would be a perfect metaphor. Your house’s breathing is almost as significant as your lungs air intake, and it would be unfair to separate the two.

  • Ventilation system aids in maintaining indoor air quality
  • Proper ventilation means healthier home by preventing airborne disease transmission, according to World Health Organization.

Air Conditioning

HVAC system is also responsible for maintaining cool temperature during warmer months. Here are the very concise steps your AC takes to keep you comfortable during summer:

  • Warm vapor refrigerant is passed through the compressor to be changed into hot refrigerant vapor and proceed to the condenser.
  • In the condenser, hot vapor is cooled and turned into hot liquid.
  • The hot liquid passes through the expansion valve creating cool liquid mist.
  • As it evaporates, it absorbs heat and returns it to the compressor.

These are very general, wide-ranging characteristics of any common HVAC system available today.

Next, we will move on to building your career as a HVAC specialist.

Work Environment
