This page covers the Okanagan Valley outside Kelowna, which has its own pages: West Kelowna, Lake Country and Peachland in the Central Okanagan, Penticton, Summerland, Oliver and Osoyoos to the south, and Vernon, Coldstream, Armstrong, Spallumcheen, Enderby and Lumby to the north.
What an evaluation finds in the Okanagan
Of the 64,120 houses in the Okanagan (single-detached, semi-detached, row houses, duplexes and mobile homes), 12% were built before 1961 and 55% before 1991, according to the 2021 Census. The typical house here dates from 1981–1990. An EnerGuide 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.
Environment and Climate Change Canada's 1981–2010 climate normal at Penticton Airport (4.2 km from Penticton) is 3,341 heating degree-days a year, with a January mean of −0.6°C. The more heating a climate needs, the more each fix is worth, which is why the ranked list in the report matters.
In the Kelowna metro area, 72% of households heat mainly with a forced-air furnace and natural gas is the main heating energy for 63% (Statistics Canada, 2023). The heating system on the report shapes the recommendations: a furnace with ducts invites a ducted heat pump, electric baseboards a ductless one.
What it costs in the Okanagan
There's no provincial price list; the City of Nanaimo quotes $400–$500 as typical for an existing home.
Most providers quote the initial (pre-upgrade) and follow-up (post-upgrade) visits separately, and organizations based in a city may add a travel fee for rural addresses. Rebate programs that pay on measured improvement need both visits, so ask for the combined price, travel included.
How a home energy assessment 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 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.

BC Southern Interior Okanagan and Thompson valleys
the Okanagan’s climate: BC Southern Interior
Hot, smoky summers and cold winters: plan cooling, filtration and heating together.
The Okanagan and Thompson valleys have cold winters and the hottest summer afternoons and driest air of any region we cover. Wildfire smoke often keeps windows shut in summer, and radon levels are among the highest in Canada. An EnerGuide evaluation here should cover heating, cooling, smoke filtration and a radon test together.
Keep smoke out: seal leaks, filter well
When smoke rolls in, windows stay shut. A tighter house with a good filter keeps indoor air cleaner; Health Canada advises the highest-rated filter your system can handle.
Size cooling and heating together
Long hot spells mean a heat pump has to handle summer cooling as well as winter heat. Equipment sized for only one season can leave you uncomfortable in the other.
Test for radon
About 1 in 3 homes across the BC Interior tested at or above Health Canada's 200 Bq/m³ guideline in the 2024 national survey, and Kelowna was among the highest municipalities.
When to book: Book the evaluation in winter (December to February suits thermal scans), and start a 3-month radon test in fall. Get cooling and filtration in place before summer smoke season.

Home energy audits in the Okanagan: common questions
How much does a home energy audit cost in the Okanagan?
There's no provincial price list; the City of Nanaimo quotes $400–$500 as typical for an existing home. Ask whether a travel fee applies to your address.
Which companies do EnerGuide evaluations in Penticton?
NRCan's list (checked October 8, 2026) shows 24 organizations registered for postal codes in Penticton, Vernon, Westbank (West Kelowna) and Winfield (Lake Country); 14 of them list all 4. Confirm they travel to your community before you book.
How long does an EnerGuide evaluation take?
The initial visit usually takes two to three hours, including the blower door test. The follow-up visit after upgrades is shorter.
Is a home energy audit worth it for an older house in the Okanagan?
55% of local houses were built before 1991 (2021 Census), and the area averages about 3,341 heating degree-days a year. Older houses in a cold climate are where a ranked upgrade list pays off most, and most rebates need the evaluation first.
Which rebates need an EnerGuide evaluation in British Columbia?
Currently: BC Home Energy Improvement Bonus ($20 for every percentage-point your home improves — $750 minimum, $2,000 maximum — or $300 for any two upgrades). Check the program page for current terms before you book.
