What an evaluation finds in Terrebonne homes
Of Terrebonne's 34,470 houses (single-detached, semi-detached, row houses and duplexes), 5% were built before 1961 and 50% before 1991, according to the 2021 Census. The typical Terrebonne house dates from 1991–1995, and an evaluation is how you find out what that means for yours: the blower door measures air leakage, the advisor inspects the attic, walls, basement, windows and heating system, and the report ranks upgrades by what they'd save.
Terrebonne gets about 4,531 heating degree-days a year and has a winter design temperature of −26.1°C, according to NRCan's HOT2000 climate data for L'Assomption, the closest comparable location in that data set (21 km away). That's about 15% more heating demand than the middle of the 70 cities we cover. The more heating a climate needs, the more each fix is worth, which is why the evaluation's ranked list matters more in some cities than others.
In the Montréal area, 54% of households heat mainly with electric baseboards, 15% with a heat pump, 10% with a forced-air furnace and 6% with a boiler and radiators; electricity is the main heating energy for 71% of households, natural gas for 5% and oil for about 2% (Statistics Canada, 2023). The heating system on the report shapes the recommendations: a forced-air furnace invites a ducted heat pump, electric baseboards a ductless one.
