Prerequisite: HVAC and Electrical System Technology I
Open to: Juniors & Seniors
Length: Year
Dual Credit: ARH208
Certification: OHSA, EPA 608 Certification, Employment readiness heat pump operation, Installation and service certification, Employment readiness gas heating certification
This course builds on the foundational skills introduced in HVAC and Electrical System Technology I. Students learn the mechanics and electrical fundamentals needed to work as a HVACR technician and/or electrician. Installation, maintenance, and repair of residential forced air heating systems, alternative energy sources, hydronic heating systems, heat pumps, and air conditioners are taught. The course will also cover advancing basic theory, multi-phase electricity, transmission and delivery systems, electronic and advanced motor controls, alarm and sensory systems, light commercial and industrial wiring, and advanced circuit design. Students continue to gain practical skills by working on trainers, mock-ups, and on-the-job projects.
