Heating and cooling systems generate condensation that must be effectively drained to prevent property damage. This module explains how condensate pumps serve as a vital solution when a system cannot rely on gravity, such as units located in basements or specific mini-split configurations. Technicians will learn about different pump sizes, the specialized requirements for high-efficiency furnaces and the essential safety mechanisms that protect a home from flooding.

This module provides an overview of the essential peripheral supplies required for a professional HVAC installation. Technicians will learn about electrical components like 30 and 60-amp disconnects and pre-built electrical whips, as well as structural supports like condenser pads and risers designed for winter operation. The module also covers specialized mounting hardware for various scenarios, including wall-mounted brackets for mini-splits and roof curbs for rooftop units, ensuring all power, gas, and refrigerant lines are properly supported and meet local building codes.

This module covers the fundamental role of copper line sets in transporting refrigerant between the indoor and outdoor components of an HVAC system. Technicians will learn how to read line set dimensions and understand the specific insulation requirements for both standard split and mini-split systems. Additionally, the module details the supplies and techniques required for professional brazing, including the use of nitrogen to protect the copper's interior from high-temperature scale formation.

This final knowledge check is designed to reinforce key concepts from the lesson and assess your understanding. You’ll apply what you’ve learned through a series of multiple choice questions, helping ensure you’re confident and ready to move forward.
