What Happens in a Home Energy Audit?

Step-by-step guide to understanding your home's energy needs—and how it unlocks CleanBC and utility rebates.

By Sam Menard · Updated July 2026 · 4 min read

Before you install a heat pump, solar panels, or insulation, a professional energy audit tells you exactly what your home needs. It's a detailed analysis that determines your eligibility for CleanBC, BC Hydro, and income-qualified rebates worth thousands.

Here's what actually happens during an energy audit and why it matters.

Why Get an Energy Audit?

An energy audit answers a critical question: Where is your home wasting energy?

Without this information, you might install a massive heat pump when weatherization would solve 60% of your heating problems for 20% of the cost. Or you might overspend on a solar system when your home still leaks air and heat.

The audit creates a roadmap. The federal Canada Greener Homes Grant is closed, so an audit is no longer needed for that grant. It's still the best way to decide what to do first. This is actually good news for planning—it forces you to think strategically instead of guessing.

The Energy Audit Process (Step-by-Step)

1

Initial walkthrough (15 minutes)

The auditor walks through your home, looking at:

  • Home age and construction type (what year built, materials)
  • Current heating/cooling systems (furnace, air conditioner, heat pump)
  • Insulation levels (attic, basement, walls)
  • Windows and doors (single-pane vs double-pane, condition)
  • Air leaks (cracks, gaps, poor seals)
2

Thermal camera scan (10 minutes)

Using an infrared camera, the auditor finds where heat escapes. Dark spots in winter = air leaks, poor insulation, or thermal bridges. This visual proof shows exactly where to focus retrofit efforts.

3

Blower door test (10 minutes)

A powerful fan temporarily covers your front door and depressurizes the home. This reveals air leaks that are impossible to spot by eye. The test measures how "tight" your home is—data that determines if you need major air sealing or just minor patches.

4

Energy bill review (5 minutes)

The auditor reviews your heating and electrical bills to estimate current energy consumption and costs. This becomes your baseline—later, you'll compare actual savings against this.

5

Report and recommendations (provided later)

You receive a detailed report showing:

  • Your home's current energy rating (EnerGuide score)
  • Where energy is lost (ranked by impact: air leaks, insulation gaps, inefficient heating)
  • Recommended upgrades in order of priority and ROI
  • Estimated costs for each upgrade
  • Estimated energy savings (in kWh and dollars)
  • Payback timeline for each measure
  • CleanBC and BC Hydro rebate eligibility and estimated amount

What the Report Tells You

A good audit report looks something like this:

What a good recommendations list looks like

A ranked list of upgrades, each with what it fixes, a rough cost range from local contractors, and which rebates it may qualify for. Air sealing and attic insulation often come near the top because they're cheap per unit of heat saved and they shrink the heat pump you need.

This tells you exactly what to do and in what order—avoiding expensive mistakes.

Cost & Time

Cost varies by region, home size and the type of assessment. Ask for the price up front.

Some programs have offered rebates toward an energy assessment. Check your utility and Better Homes BC for what's open now before you book.

Time required: 45 minutes in-home, then 1–2 weeks for the detailed report.

Who Should Conduct Your Audit?

Look for auditors certified by:

A contractor's free in-home estimate is useful, but it isn't the same as an independent assessment. Know which one you're getting.

Outside BC — including the US — the equivalent credentials are BPI Building Analyst and RESNET HERS Rater. See our full guide to assessment questions and certifications for the cross-region breakdown.

Next Steps After Your Audit

  1. Review the report and ask your auditor to explain any unclear sections
  2. Get quotes from installers for the top 2–3 recommendations
  3. Check CleanBC and BC Hydro eligibility—if you qualify (including income-qualified programs), apply before starting work
  4. Sequence your upgrades following the audit's priority order (not random guesses)
  5. Track your energy bills after each upgrade to confirm actual savings
