The role of residential contractors, who install heating, ventilation, and air-conditioning systems in homes and condominiums, is becoming more complex. No longer just the people who install furnaces, these contractors must be knowledgeable not only about heating, but also about ventilation, humidification, cooling, and indoor air quality, And, they must be able to design systems specifically suited to each project. Residential contractors must be able to integrate the latest technologies such as high-velocity systems, in-Hoor radiant heating, and combination systems. That is why the Toronto-Residential Air Handling Group is now known as the Residential Heating Ventilation Contractors Association (RHVCA).
