By integrating our Alize variable speed outdoor condensing unit with our Chinook modulating gas furnace and their proprietary communicating thermostat, we have developed the Right-Sized System which is exclusive to Dettson. The Right-Sized System® will provide homeowners with unequalled comfort that until now has not been available to them. Dettson is the first manufacturer in North America to offer the Right-Sized System® designed for today’s tighter, well insulated and more energy efficient homes. High performance homes require a central system with longer operation cycle times rather than the short cycling typical of most HVAC equipment. The new building codes coupling with volunteer programs such as Energy Star, HERS, R2000 and LEED result in energy efficient homes that allow much less heat loss during winter and less heat gain during summer. By working with builders and third party labs, Dettson developed the Right-Sized System which offers less indoor temperature variation and greater humidity control. Because the central system is designed for longer run times with lower airflows it is also much quieter than typical systems
