Calgary Home Energy Audit Guide: Who to Call, Leaky Windows and Whether a Heat Pump Pays (Winter 2026)

Short answer: Start with an EnerGuide home evaluation from a service organization registered with Natural Resources Canada. A registered energy advisor tests your home's airtightness with a blower door, checks insulation, windows, doors and heating, then gives you a rating and an upgrade report. The job is measuring, not selling, so you get a to-do list before any contractor quotes.

A client texted me this week with winter on their mind. Everyday bills keep climbing, and they were wondering about their windows and doors: who could test the house without trying to sell them something, which windows and doors are actually leaking heat, and whether a heat pump would be wise. Their last line was "where would I start?" It's a great question, and the honest answer can save a lot of money, so here is the full version, with every program checked on its official page on November 6, 2026.

Who can test my home's energy use without trying to sell me something?

The neutral option in Canada is an EnerGuide home evaluation. It's done by an energy advisor registered with Natural Resources Canada who works for a registered "service organization" that you book directly (NRCan, EnerGuide home evaluations). The advisor goes from basement to attic and records:

• how airtight the house is, using a blower door test
• insulation levels in the walls, ceilings and basement
• the number, type and location of every window and exterior door
• the size and efficiency of your furnace, air conditioner and water heater, plus ventilation

That data goes into NRCan's energy modelling software. You get an EnerGuide rating for the home and a report showing which upgrades would help most.

How do I find a registered energy advisor near Calgary?

Use NRCan's Find service organizations for existing homes page. Type the first three characters of your postal code (most Calgary codes start with T2 or T3), call two or three of the organizations listed, and ask for their price and their earliest opening. The same page lets you check that a company you've already booked is really registered.

NRCan is clear about one red flag: registered service organizations don't sell door to door or through unsolicited calls or emails. If someone knocks offering a "free government energy audit," say no thanks and book one yourself.

One tip from me: when you call, ask whether the company also sells or installs windows, insulation or heating. Some do. That doesn't make the report wrong, but you'll want the report in hand before anyone gives you a quote.

What does an EnerGuide evaluation cost?

NRCan says the cost varies by provider and province, and that a pre-retrofit plus post-retrofit evaluation together run $600 to $1,000 on average, typically paid after each evaluation is completed (NRCan). That figure covers both visits. If you only want the first one, ask for that price.

On the day, clear a path to the attic hatch and the furnace room, empty the ashes from any wood fireplace, and don't run the furnace, hot water, dishwasher or washer during the blower door test. The fan can interfere with gas appliances, so the advisor turns them down while the test runs.

How can I tell which windows and doors are leaking heat?

Windows, doors and skylights can account for up to 35% of a home's total heat loss, according to NRCan's Keeping the Heat In guide. But a drafty window doesn't always need replacing, so it pays to find the leaks first.

• During the blower door test. The fan pulls air out of the house, so outside air rushes in through every gap. That's when leaks around sashes, door frames and thresholds are easiest to find. NRCan notes that an infrared (thermal) scan done during a blower door test is a powerful way to spot air leaks and missing insulation. It isn't on the standard EnerGuide checklist, so ask the service organization if the advisor offers it.
• Do it yourself on a cold day. NRCan's guide suggests holding two or three lit incense sticks near suspect spots. Strong leaks blow the smoke away and make the tips glow; slower ones pull the smoke toward the gap.
• Where to look: around window sashes and casings, door thresholds and frames, electrical outlets and switches, exhaust fans and vents, ceiling light fixtures, corners where walls meet, and baseboards.

Should I repair or replace my windows?

NRCan lists several steps short of full replacement: servicing latches and cranks, caulking and weatherstripping, adding glazing or storm windows, or putting new sashes and glass into frames that are still sound. Sometimes full replacement with ENERGY STAR certified windows is the right call. Your EnerGuide report will show where windows rank against everything else in the house. That stops you from spending window money when the real problem is the attic.

What should I fix first before spending big?

My order, based on NRCan's guidance and what I see in Calgary homes every week:

1. Seal the air leaks. NRCan says most houses benefit from air leakage control. Weatherstripping on doors and opening windows, caulking around trim, and gaskets behind outlet covers on outside walls are weekend jobs.
2. Top up the attic. A poorly insulated attic is one of NRCan's typical retrofit opportunities, and it's worth checking early in any older home.
3. Basement and walls, ideally when you're finishing or renovating anyway.
4. Windows and doors that the report or the thermal scan says are really losing heat.
5. Heating equipment last. NRCan points out that once the building envelope is upgraded, a smaller heating system may do the job. That's a good reason to fix the shell before you size a new furnace or heat pump.

Moisture matters too. As you tighten a house, ventilation matters more, so ask your advisor about it.

Is a heat pump worth it in Calgary?

It can be, but in a house already heated with natural gas, it's a closer call than the ads suggest.

Do heat pumps work in Calgary's cold?

NRCan says cold-climate air-source heat pumps can operate when it's as cold as -30°C, with supplemental heat needed below that (NRCan, Heat pumps). Most other air-source units have a minimum operating temperature, which NRCan puts between -15°C and -25°C for newer models. Efficiency also falls as it gets colder. NRCan's heat pump guide puts a typical coefficient of performance (units of heat per unit of electricity) at 2.0 to 5.4 at 8°C but only 1.1 to 3.7 at -8°C (NRCan, Heating and cooling with a heat pump). Air-source heat pumps last about 15 to 20 years.

What is a hybrid or dual-fuel setup?

In a hybrid system, the heat pump handles mild weather and your gas furnace takes over when it gets colder. NRCan describes it as a good option when a heat pump replaces a central air conditioner. The system switches at a set "balance point," either the temperature where the heat pump can't keep up or where gas becomes the cheaper fuel. For many Calgary homes with a working furnace and an old A/C unit, this is the setup worth pricing.

Will a heat pump lower my bills in Alberta?

Here are the energy-only default rates Alberta's Utilities Consumer Advocate lists for November 2026 (UCA default rates):

Delivery, admin and other charges are extra on both bills and aren't included. Gas rates change monthly.

On energy charges alone, electricity costs roughly 18 times as much as gas for the same amount of energy. A heat pump would need to move about 17 units of heat per unit of electricity to match a 95%-efficient gas furnace, and NRCan's range at -8°C tops out at 3.7. The federal rebate page says it plainly: for homes heating with natural gas, switching to a heat pump may not lower heating bills (Government of Canada).

So when does a heat pump make sense here?

• Your air conditioner is dying or you want cooling. A heat pump gives you A/C plus some efficient shoulder-season heat.
• Your furnace is near the end of its life and you're pricing replacements anyway.
• You heat with electric baseboards, an electric furnace or propane. The federal announcement cites average savings of more than $1,400 a year for households heating with oil, propane or electric resistance (Government of Canada, Oct 8, 2026).
• You value lower emissions and are fine with a payback that depends on future rates.

Ask your energy advisor to model the heat pump option for your house. That's a far better guide than a sales quote's savings estimate.

What rebates and financing can Calgary homeowners get right now?

I checked each program on its official page on November 6, 2026. These change often, so confirm before you sign anything.

Utility rebates: I couldn't confirm any current gas or electric utility rebate for Calgary homes on an official page, so ask your energy retailer and your advisor what is running when you book.

Do energy upgrades help when you sell a Calgary home?

In my experience, buyers ask about utility bills, especially in older homes and in winter. A recent EnerGuide report and a folder of receipts for the attic insulation, windows or furnace give them something concrete instead of a guess. Keep those invoices anyway. NRCan says programs with a post-retrofit check may ask for them.

One thing to know if you ever use CEIP: the City says the financing stays with the property. When you sell, you pay off the balance with no penalty, or you disclose it and the buyer takes it over. The City also tells buyers to check for a CEIP loan before making an offer.

Frequently asked questions

How much does an EnerGuide home evaluation cost in Calgary?

Natural Resources Canada says the price depends on the service organization and the province, and that a pre-retrofit plus post-retrofit evaluation together cost between $600 and $1,000 on average, typically paid after each evaluation is completed. Ask the service organization for its price before you book.

Does an EnerGuide evaluation include thermal imaging?

Not necessarily. The standard EnerGuide evaluation measures airtightness with a blower door test plus insulation, windows, doors and mechanical equipment. If you want an infrared scan to pinpoint leaks, ask the service organization whether the advisor offers one during the blower door test and what it costs.

Do I need an energy audit to get the new federal heat pump rebate?

No. The Government of Canada says the National Heat Pump Rebate needs no energy audit before or after installation. Applications open through an online portal in early 2027, and eligible heat pumps installed from November 1, 2026 can count retroactively.

Can a heat pump heat a Calgary house in a cold snap?

Cold-climate air-source heat pumps can operate at outdoor temperatures as cold as -30°C, according to Natural Resources Canada, but their efficiency drops as it gets colder and a backup heat source is still needed below that. In a hybrid setup, the backup can be your existing gas furnace.

Is the Canada Greener Homes Grant still available?

No. The Canada Greener Homes Grant is closed: December 31, 2025 was the final day to upload documents. The Canada Greener Homes Loan is also closed because its funding is fully committed.

Is Calgary's Clean Energy Improvement Program open?

Not right now. As of November 6, 2026, the City of Calgary says Residential CEIP intake is closed until winter 2026/2027. When it is open, it is financing repaid through your property tax bill, not a rebate.
