During your HVAC Technician diploma, you will learn to work safely with chemicals.

Turn Off the Electricity While you Work 

When working with units that have a water system or have general electrical issues, it is safer to turn off the main circuit breaker before starting work. Water is a conductor of electricity and can cause electrocution. Water leaking onto the unit you are working on may also be damaging to the unit, as it may cause a short circuit. This can be not only damaging for the unit but is a safety and fire hazard, as well. Additionally, it will be essential to analyze a unit before you begin working on it to see if there are any fluid leaks. This will help you better understand if you need to turn off the main circuit breaker. 

The HVAC training you receive at NATS will help you identify leaks, teach you how to fix them, and help you understand the safety practices to follow throughout your career.
