Yes. Atlantis HVAC Systems specializes in oil-to-gas furnace conversions across the Greater Toronto Area, including Oakville, Burlington, Toronto, and Etobicoke. These conversions improve efficiency and reduce long-term operating costs.
An HRV (Heat Recovery Ventilator) replaces stale indoor air with fresh outdoor air while retaining heat energy. Homes with poor ventilation, humidity issues, or allergy concerns often benefit significantly from an HRV installation.
