This course builds on fundamental heat pump theory and design skills to develop competencies for retrofitting residential air-to-air heat pump systems in existing homes. It complements MZEB 2111 (TECA’s Quality First Air to Air Heat Pump System Design – Residential) by focusing on retrofit-specific design and planning nuances essential for high-performance outcomes. Key topics include electrical service capacity, evaluating and reusing existing ductwork, planning detailed building enclosure penetrations, CSA F280-12 load calculations and equipment zoning, system configurations, ductwork modifications, managing condensate drains, controls optimization, supplementary heating, ventilation systems, and coordination of retrofit measures. The course builds on prior residential HVAC knowledge gained through prerequisite training and prior experience.

Air-to-air heat pumps are highly relevant to a low-carbon economy because they provide efficient heating and cooling using electricity instead of fossil fuels, significantly reducing greenhouse gas emissions from buildings. By transferring heat rather than generating it through combustion, they use far less energy than conventional systems and support the transition to cleaner, electrified infrastructure powered by renewable energy. In regions like British Columbia, where electricity is largely hydro-based, heat pumps can operate with very low emissions, making them a key technology for building decarbonization, energy efficiency, climate targets, and the growth of green jobs in construction, HVAC, and clean energy sectors.
