Course Description

This course introduces builders, contractors, and industry professionals to the fundamentals of residential HVAC design and installation, with a focus on new home construction. Learners will gain a practical understanding of how heating systems, ductwork, and mechanical ventilation work together to create comfortable, efficient, and healthy indoor environments.

This course covers:

• General HVAC Fundamentals: Key design standards (TECA, HRAI, SMACNA, ASHRAE) and CSA F280 heat loss/heat gain calculations that determine system sizing.
• Heating Systems: Common residential heating options, including furnaces, heat pumps, ductless mini-splits, electric baseboards, and hydronic systems, with guidance on equipment selection and commissioning.
• Ductwork: Principles of duct design, sizing, and installation; supply and return air distribution; sealing, insulation, and fire protection requirements in line with national and provincial codes.
• Ventilation: Mechanical ventilation strategies, HRV/ERV system design and balancing, minimum airflow requirements (CSA-F326, ASHRAE 62.2), and managing indoor humidity for comfort and durability.

By the end of this course, learners will be able to:

• Distinguish between types of mechanical ventilation systems
• Explain the need for mechanical ventilation in new houses
• Describe the factors involved in carrying out heat loss and heat gain calculations
• Describe the most common space heating equipment options for new construction
• Describe common delivery systems and controls for space heating

This course combines technical guidance with practical examples and knowledge checks, ensuring learners can confidently apply HVAC fundamentals to residential projects.
