Each house stands for one in ten of Saint John's 19,705 houses (single-detached, semi-detached, row and duplex), drawn by when it was built. The glow shows the usual pattern: older houses tend to be leakier and less insulated. More snow in the drawing means more heating degree-days: a longer, colder heating season.

What an evaluation finds in Saint John homes

Of Saint John's 19,705 houses (single-detached, semi-detached, row houses and duplexes), 34% were built before 1961 and 78% before 1991, according to the 2021 Census. The typical Saint John house dates from 1961–1970, 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.

Saint John gets about 4,580 heating degree-days a year, a measure of how much heating its climate needs, and its winter design temperature, the cold day heating systems are sized for, is −22.5°C. Those figures come from the climate data for Saint John in HOT2000, the home-energy software Natural Resources Canada (NRCan) gives energy advisors. That's about 16% more heating demand than the middle of the 70 cities we cover. A long heating season: air sealing and insulation pay back well, and every leak costs money for months.

In the Saint John area, 38% of households heat mainly with electric baseboards and 32% with a heat pump; electricity is the main heating energy for 46% 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 Saint John

Through the Total Home Energy Savings Program, a Certified Energy Advisor charges $99 + HST, covering both the initial and final evaluations.

How a home energy assessment (EnerGuide evaluation) 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.

Atlantic Canada Maritimes and Newfoundland

Saint John’s climate: Atlantic Canada

Damp, windy, icy winters and costly oil: switch to heat pumps, seal, test for radon.

Atlantic winters are wet, windy and icy rather than extremely cold, and summers are mild. Heating oil is still common and its price rose sharply in 2026, while heat pumps already heat many homes. An EnerGuide evaluation here should plan the move off oil, seal wind-driven leaks, fix moisture before insulating, and include a radon test.

In Saint John: Saint John has cool summers but wet, windy winters, with enough wind-driven rain that new walls must have a rainscreen. Heating oil averaged about $2.60 a litre here in September 2026, the highest of the Atlantic cities tracked, so plan a move off oil.

  1. Plan your move off oil

    Oil prices rose 65% to 81% in a year, and corrosion is a leading cause of oil tank leaks. Cold-climate heat pumps can be up to three times as efficient as oil heating.

  2. Seal wind-driven leaks and the attic

    Wind pushes cold air through gaps, and heavy, wet snow with frequent freezing rain makes a leaky attic prone to ice dams.

  3. Fix moisture before you insulate

    Halifax, St. John's, Saint John and Charlottetown get enough wind-driven rain that new walls must have a rainscreen. Stop water getting into walls and basements before adding insulation.

When to book: Book the evaluation from December to March, on a calm day, for the best blower door and thermal scan results. Have oil equipment checked before winter, and start a 3-month radon test in fall.
