See your cost breakdown
The Home Diagnostic gives you a detailed breakdown of your energy use and costs. You’ll find out how much you spend on heating, laundry, lighting and so on.
Simulate the impact of changes you might make
How much money could you save by turning down the temperature in your house a degree or two? What difference will doing laundry in cold water make? Will buying a solar pool cover really save you money? The Home Diagnostic What If? tool gives you answers.
How do you do the Home Diagnostic?
To do the Home Diagnostic, you answer a set of up to 127 questions. To give you the most precise results possible, the tool analyzes your answers taking into account the amount of electricity you actually use in a year.
How’s it different from Dare to Compare?
Dare to Compare asks only 11 questions, and its purpose is to compare your overall electricity use with that of similar households. The Home Diagnostic does a much more detailed analysis. Both services are free.
Conditions for obtaining a home diagnostic
If you’re a residential customer who pays Rate D or DT, you can do the Home Diagnostic, no matter whether you’re a homeowner or a tenant.* You can analyze your principal residence, secondary residence or cottage. The rate you pay is indicated on your bill.
You have to meet the following conditions in order to obtain an accurate, useful analysis:
- The electricity bill must be in your name, your contract must be current and you must live at that service address
- You must pay Rate D or DT
- Your consumption history must include an analysis period of at least 350 days of occupancy
- The history has to comprise at least five billing periods with actual meter readings
- No more than one bill can be based on an estimate (E)
- If there is an estimate, it can’t be for the first or last period analyzed
- Your building must be exclusively residential
*The Home Diagnostic service is not available to Nunavik customers because of major differences in building types. Customers of municipal utilities cannot use the service, because Hydro‑Québec doesn’t have access to their electricity use data.
