Understanding & Learning the Basics of HVACUnderstanding & Learning the Basics of HVAC - To understand air conditioning and heat pump applications you will need to study refrigeration. Both air conditioners and heat pumps use refrigeration to move heat. Air conditioners move heat outside in the summertime using the process of refrigeration while heat pumps move heat in both directions (to the inside in the winter and to the outside in the summer) using the principles of refrigeration.

Understanding & Learning the Basics of HVAC

Air Conditioning and Heat Pump Applications

The basics foundation of refrigeration is understanding temperature-pressure relationships, the compression cycle, and how different refrigerants absorb heat. You have to understand BTU’s are a way to measure heat. You have to understand the four major components in the refrigeration cycle. The compressor, the evaporator, the condenser, and the metering device and understand how all these components work together to make the refrigeration system work.

Finally, a basic foundation in refrigeration will require you to learn basic physics of temperature, chemicals used for refrigerants, gas laws, and all the mechanical components that work together to make the refrigeration process work. This all the basics of a good HVAC education.

Understanding & Learning the Basics of HVAC – Tools and Materials

and materials used for performing heating and cooling work is necessary to enjoy a successful career in HVAC. From tubing cutters to hammers and screwdrivers, to multi-meters and refrigeration compound gauges you will find yourself working with all these various tools. Sheet metal, screws, tape, and piping are used heavily in performing many jobs and it is important to understand the various types of materials used for different applications.

Knowledge of basic math is good to make the proper measurements of materials and when working with basic electrical circuits. Study the materials used and use them for the proper application especially wiring. Using the proper wire and wire size for electrical wiring is essential and necessary for safety. Using the correct tubing and piping for HVAC piping jobs requires a good basic knowledge of piping and piping installation. Understanding tools and materials used in HVAC is very important to advance.

Understanding & Learning the Basics of HVAC – HVAC Controls

HVAC Controls (DDC) is a specialized field in commercial HVAC but in many residential applications it is important to understand basic electrical circuits and electrical components used in HVAC. This is especially true of you want to be an HVAC service technician who troubleshoots and services HVAC equipment. You have to have a good basic understanding of refrigeration, electrical circuits, and mechanical systems if you want to be a good HVAC service technician.

Installer HVAC technicians need to have a basic understanding of these systems also however it is not necessary for an installer technician to understand all the essentials of troubleshooting as well as the HVAC service technician. Many service technicians start off as equipment installers and work hard to learn as much about all the basics they can before moving up to service technician.

Learning the Basics of HVAC – HVAC Rules and Regulations

There are many rules and regulations one must follow to be a successful HVAC technician. These rules and regulations include: EPA 608 Licensing requirements for handling refrigerants, HVAC company rules and regulations (obviously), local, state, and national codes for HVAC and electrical. Some state, local or national agencies will require an HVAC technician to possess an HVAC Journeyman’s or HVAC Masters license before they are allowed to work in the trade.

The company where you are employed should have all the information for obtaining an HVAC license. All these things are requirements for good HVAC technicians to learn and comply with as the work they way up the ladder to success.

Learning the Basics of HVAC – Conclusion

If you want to be in the HVAC field working as a technician you will need to study hard and work your way up the ladder. It will not be easy but with perseverance and hard work you can be the best HVAC technician out there. Good luck in your career and learning.
