About the Course:

This Air Conditioner Maintenance microcredential equips students with the essential skills and knowledge to perform routine air conditioner (AC) maintenance in residential and light commercial settings. Students will learn industry-standard procedures for cleaning evaporators and condenser coils, maintaining drain systems, inspecting refrigerant lines, and verifying refrigerant charge levels. Emphasis is placed on manufacturer compliance, tool usage, and preventive maintenance practices that improve system efficiency and extend equipment life. Advance your skills further with our HVAC maintenance training program.

Learning Objectives:

  • Properly clean evaporator coils using the correct tools, cleaning agents, and manufacturer guidelines.
  • Maintain and treat AC drain pans and lines to prevent blockages and biological growth.
  • Locate, clean, and maintain condensing units and outdoor coils using safe and effective methods.
  • Visually inspect refrigerant line insulation and identify missing or deteriorated sections.
  • Check refrigerant levels using pressure gauges and manufacturer charging charts to ensure optimal system performance.

Course delivered via LMS and requires an Oculus VR headset for hands-on VR simulations.
