Call the energy advisor first
Some rebates want an advisor involved before any work starts. Ontario's assessment stream needs the pre-audit before any work, and a rebate can be lost if the work starts earlier.
Before work starts Where the advisor goes
- 1Energy advisor visitsTests the house. Writes the EnerGuide evaluation and, for a heat pump, the heat load calculation.
- 2You choose upgradesIn the right order: sealing and insulation can come before the heat pump.
After work starts
- 3InstallerQuotes and fits equipment sized to the calculation.
- 4Final checkSome programs also want a second evaluation when the work is done.
What an energy advisor does
A registered advisor is a third-party expert who does not sell equipment, so the advice is about your house, not a product. These are the standard services. Ask this company which ones it offers.
EnerGuide evaluation
Shows where your house is losing energy and which upgrades will make the biggest difference, so you spend money in the right order.
You get: an EnerGuide rating and a report to take to a rebate program.
Heat load calculation
Works out how much heating and cooling the house actually needs, room by room, so the heat pump is sized properly.
You get: a number any installer can quote against.
Airtightness testing
A blower door test pulls air through the house to measure how leaky it is.
You get: a before and after measure of how airtight the house is.
New builds
Advisors also deliver NRCan's ENERGY STAR for New Homes and R-2000 programs for new builds.
Why the visit matters
A heat load calculation done without visiting the house is an estimate. Equipment sized without one is often bigger than the house needs, which costs more up front and runs less efficiently.
Illustration only, not measured data.
The advisor starts outside and moves inside, then enters the data into energy software that calculates your rating (NRCan, read October 20, 2026).

Ontario Home Renovation Savings: assessment stream
The pre-audit comes before any work, and a post-audit finishes it by December 31, 2026. You need at least two qualified upgrades. A registered energy advisor at an authorized service organization does both audits.

What we checked
Listed by Natural Resources Canada: find service organizations for existing homes. This is the official list we use, not a paid placement.
We could not match this company to a rated Google Maps listing, so it is not in our city rankings.
Nobody pays to be listed and money never changes where a company ranks.
Registered energy advisors are independent businesses. Ask for the price of every visit up front, and whether their report counts for the rebate program you plan to use.
Questions people ask
Do I need an energy advisor?
Not for every project. Ontario's Home Renovation Savings assessment stream needs one: a registered energy advisor at an authorized service organization does the pre-audit and the post-audit. The attic-only stream does not need an assessment.
How is an advisor different from an installer?
An advisor tests and measures your home and does not sell equipment. An installer fits it. The advisor's numbers help the installer size it properly.
What does it cost?
NRCan says both evaluations together average $600 to $1,000, depending on the provider and province, and are usually paid after the service. Ask this company for its own price. NRCan, read October 17, 2026. The program also pays a $600 audit rebate in its assessment stream, so ask the advisor how that shows up for you.
Can I book one after the install?
For the assessment stream, no. The pre-audit has to come before any work starts, and the post-audit must be done by December 31, 2026.
How do I find a registered advisor?
Homeowners book through an NRCan licensed service organization, which sends a registered advisor. Ontario's assessment stream needs an advisor at an authorized service organization. NRCan lists them.
