While furnaces and air conditioners are quite possibly the move important piece in a house, the average homeowner person may not realize how integrated these heating and air conditioning systems are! It’s mainly for this reason that becoming an HVAC technician has become an in-demand career choice. HVAC technicians also make sure heating and cooling systems follow federal and state regulations and guidelines.

To do this, they use a wide variety of tools. Look inside an HVAC technician’s toolbox and you’ll find specialized equipment like voltmeters, combustion analyzers, and carbon monoxide testers. HVAC technicians have to be able to read and understand blueprints, schematics and technical data, so they can locate and repair these systems.

Technicians study the principles of refrigeration and learn the basics and applications of refrigeration systems, including the physical and chemical laws that apply to heating and cooling systems. They also learn to troubleshoot and repair residential gas heating systems.

Technology runs most of these systems today, so HVAC technicians must be able to use a wide collection of software programs and can monitor their work on their tablets or smartphones. They even have to possess a general understanding of plumbing because in some older homes, boilers and radiators are still in use.

Remember the “V” in HVAC? It’s crucial to know how to effectively measure and regulate the heated or cooled air flowing through a home. Specialized formulas are used to calculate load capacities through the HVAC systems.
