Every home audit and test, city by city

Pick the service, then your city. Each local page pulls together the numbers that change the job where you live: the climate, how old the houses are, what the province requires, what it costs, and who does the work.

An energy advisor’s kit on a front-hall bench: infrared camera, pressure gauge with tubing, tape measure, headlamp and a floor sketch

Energy: find where the heat and money go

Usually done during an EnerGuide evaluation by an NRCan-registered energy advisor.

Home energy audits

An EnerGuide evaluation by an NRCan-registered energy advisor: blower door test, full house inspection, an energy rating and a ranked upgrade list.

Varies by province

A red blower-door panel with a large fan fitted into the front doorway of a brick bungalow, a pressure gauge on a stool inside

Blower door testing

A calibrated fan depressurizes the house to measure air leakage and show where the leaks are.

Included in an EnerGuide evaluation

Hands holding an infrared camera aimed at a ceiling corner beside a frosty window; the screen shows a cold streak

Thermal imaging inspections

An infrared camera maps cold and warm surfaces to find missing insulation, thermal bridges and hidden moisture.

Usually included with an evaluation; confirm

A kitchen table with a house floor plan, a laser measure, a tape measure and a laptop showing the plan

Heat loss calculations

A room-by-room CSA F280 calculation of heat loss at the local design temperature: the right way to size a heat pump or furnace.

About $150–$400 standalone

A duct-testing fan on a basement floor connected by flexible duct to a furnace, a pressure gauge hanging from a joist

Duct leakage testing

Pressure-tests ductwork and measures airflow at each register to find where heated air disappears.

About $200–$450

A gloved hand inserting a combustion analyzer probe into a furnace flue pipe in a basement

Combustion safety testing

Checks that furnaces, water heaters and fireplaces vent safely, especially before a house is tightened.

Included with an evaluation when you have fuel-burning appliances

A heat recovery ventilator on a basement wall with four insulated ducts running up between the joists

Ventilation and humidity assessments

Measures air exchange and humidity and checks that bath and kitchen fans actually move air outside.

Included in an evaluation; HRV sizing may be extra

Loose-fill insulation between attic joists, a yellow ruler showing its depth and frost on the roofing nails above

Attic insulation inspections

Insulation depth and condition, air bypasses and ventilation, plus red flags like vermiculite before anyone disturbs it.

Included in an EnerGuide evaluation

Utility bills and a phone showing a monthly energy-use chart on a kitchen table

Energy bill analysis

Twelve months of electricity and gas use, weather-normalized and split into heating and baseload: the baseline every savings estimate needs.

Free to do yourself; part of an evaluation

Home health: test the air, water and materials

Specialty tests by certified professionals and accredited labs, and some you can do yourself.

A small digital radon monitor on a bookshelf in a finished basement family room

Radon testing

A long-term test (at least three months, in the heating season) measures radon against Canada's 200 Bq/m³ guideline.

$30–$60 for a DIY long-term kit

A carbon monoxide alarm on an upstairs hallway wall outside the bedrooms at night

Carbon monoxide testing

CO alarms in the right places, plus a check that fuel-burning appliances vent safely.

$40–$80 per alarm

A moisture meter pressed into water-stained basement drywall, an air-sampling pump on a tripod nearby

Mold and air quality testing

Air or surface sampling when you suspect hidden mold, paired with a hunt for the moisture that feeds it.

About $300–$600 for a sampling visit

A gloved hand holding a sealed sample bag above vermiculite insulation between attic joists

Asbestos and vermiculite testing

Lab analysis of samples from suspect insulation, tiles, plaster or duct wrap before renovation disturbs them.

About $50–$150 per lab sample

A gloved hand swabbing layers of cracked old paint on a wooden window sill

Lead paint testing

Swab kits screen painted surfaces; a lab or an X-ray reading confirms before renovation disturbs old paint.

$15–$40 for swab kits

Filling a water-sample bottle at a farmhouse kitchen tap with the aerator removed, snowy fields and a barn outside

Well water testing

Bacteria testing at least once a year and periodic chemistry for homes on private wells.

Varies by province

Commercial buildings

Engineering-grade audits for businesses, institutions and multi-unit buildings.

An auditor walking between rooftop heating and cooling units on a snowy commercial roof

Commercial energy audits

An engineering audit of an office, apartment, retail or industrial building, scoped to ASHRAE Standard 211 levels 1 to 3.
