The HVAC Service Protocol course prepares the student for the ever-changing HVAC industry by training that includes the technician’s perspective of business smart, people smart, and equipment smart. This type of training helps quickly advance the new service tech by teaching scientific service protocol in every class session. This protocol sets the guideline for a consistent successful service call experience for the contractor, the client, and the technician. Today’s HVAC contractor requires more of their service technicians than at any other time in the industry’s history. Today’s service technicians must be smarter than their predecessors. The typical service call involves 3 vital aspects of business in the 21st century. Successful service businesses require technician proficiency in areas of company profitability, customer relationship, and technical performance. The HVAC Service laboratory is set up with 8 individual mini training homes which encompass as many as 52 various system malfunctions, including mechanical, electrical, and airflow. The student is educated via 24 different service calls, which over a 100-hour period exposes them to about 2 years of in-field experience. The most effective, and we would say the only, way that a person learns the trades is by putting their hands-on. This course was designed around the service technician and what they must know to have a solid foundation to enter their new career.
