What an evaluation finds in Kingston homes
Of Kingston's 38,680 houses (single-detached, semi-detached, row houses and duplexes), 24% were built before 1961 and 67% before 1991, according to the 2021 Census. The typical Kingston house dates from 1971–1980, 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.
Kingston gets about 3,935 heating degree-days a year and has a winter design temperature of −21.8°C, according to NRCan's HOT2000 climate data for Trenton, the closest comparable location in that data set (82 km away). That's right around 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 Kingston area, 58% of households heat mainly with a forced-air furnace; natural gas is the main heating energy for 50% of households (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.
What it costs in Kingston
Typical Ontario prices are about $500–$700 for the initial EnerGuide evaluation and $200–$450 for the follow-up, plus HST where it applies. Windfall Ecology Centre charges $500 + HST for the initial evaluation and $250 + HST for the follow-up, Reep Green Solutions charges $540 and $406 with no HST, and City-backed programs in Ottawa and London quote $500–$700 as typical for the first visit. Only assessments from the seven HRSP-approved organizations qualify for the $600 Home Renovation Savings rebate, and none of the seven publishes a price.
Most providers quote the initial (pre-upgrade) and follow-up (post-upgrade) visits separately. Rebate programs that pay on measured improvement need both, so ask for the combined price.
How it works
- Initial evaluation, about 2–3 hours. The advisor measures and inspects the house and runs the blower door test.
- Report and EnerGuide rating. You get the home's energy rating in gigajoules per year and a list of recommended upgrades with estimated savings.
- Do the work. Most rebate programs only count upgrades done after the initial evaluation.
- Follow-up evaluation. A second visit measures the improvement, which is what most rebates pay on.
