How to Use the Energy Savings Report Generator
Pick the province the building is in to load typical electricity and gas rate defaults, or enter custom rates from a recent utility bill for the most accurate result.
Choose the current fuel type, enter the annual energy use from a utility bill history, and check the existing efficiency. Gas, propane, and oil systems use GJ, while electric systems use kWh.
Select the replacement equipment type, its rated efficiency, and the installed cost, using only the extra cost over a like-for-like replacement if the old system has to be replaced anyway. Add any confirmed rebate amount.
Click Generate Savings Report to see annual cost for both systems, the yearly savings, and the payback period on the net installed cost.
Understanding HVAC Energy Savings Reports in Canada
An energy savings report answers the question every client asks before agreeing to a bigger equipment bill: how long until this pays for itself? Getting that answer right depends on using the right utility rates, the right efficiency figures, and being honest about what the payback calculation does and doesn't account for.
Why Utility Rates Vary So Much Across Canada
Residential electricity in Canada runs from about 8 cents per kWh in Quebec to over 20 cents in Alberta and Nova Scotia, according to Hydro-Québec's annual comparison of electricity prices, which uses a 1,000 kWh month and excludes tax. The provincial defaults in this tool come from that April 2025 edition. Natural gas rates carry their own regional and seasonal variation. Because these differences are large enough to swing a heat pump from clear savings to no savings at all, using the correct provincial rate, or better yet a rate pulled directly from the client's own utility bill, matters more here than in almost any other HVAC calculation.
Simple Payback vs. the Full Picture
This report calculates a simple payback period: the net cost of the new system, after any confirmed rebate, divided by the annual savings, using current rates held flat over time. If the existing equipment has to be replaced anyway, enter only the extra cost over a like-for-like replacement, since that is the money the savings actually need to earn back. The method leaves out financing costs, maintenance differences between systems, and any change in utility rates over the equipment's service life. Oil and propane prices in particular swing from month to month, so check the latest figures on Natural Resources Canada's fuel price pages and update the fuel price field before presenting a number.
Handling Rebates Correctly
Only include a rebate in the payback calculation once it's confirmed for the specific equipment and program the client is actually pursuing. Program rules and funding availability change frequently, and quoting an unconfirmed rebate as fact can create an awkward conversation later if the client doesn't qualify. Subtracting a confirmed rebate from the installed cost before running the calculation gives an accurate, defensible payback number.
Pairing This Report With the Emissions Picture
Cost and emissions savings don't always point the same direction, especially in provinces where the grid still carries a meaningful fossil fuel share. The carbon report generator in this category compares the two systems directly, and the carbon footprint calculator gives a wider view of a household's emissions. Showing a client both the cost case and the emissions case makes for a better proposal than assuming one of them decides the question.
A Realistic Starting Point
Getting accurate annual energy use and efficiency for the existing system matters more than almost any other input here. Pull real numbers from twelve months of utility bills where possible rather than a rough estimate, and adjust the existing efficiency field if the old furnace is well below the 85 percent default. Where no billing history exists yet, such as for a new build, estimate annual heating energy from the design heat loss and local heating degree days with the degree day energy calculator, and use that figure as the starting point.
Frequently Asked Questions
Payback period is calculated by dividing the cost the savings need to recover, after any confirmed rebate, by the projected annual energy cost savings. When the old equipment has to be replaced anyway, that cost is the extra spent over a like-for-like replacement, and when it doesn't, it is the full installed cost. A system that costs 4,000 dollars more than the baseline replacement but saves 800 dollars a year has a five-year simple payback, not accounting for financing costs, maintenance differences, or future utility rate changes.
Yes. In Hydro-Québec's April 2025 comparison, average residential electricity prices before tax ranged from about 8 cents per kWh in Montréal to about 23 cents per kWh in Calgary, with Halifax near 20 cents. Natural gas rates also vary by region and by season. These differences can significantly shift the payback period for the same equipment upgrade depending on where the building is located.
Yes, subtracting any confirmed rebate amount from the installed cost before calculating payback gives a more accurate picture, since rebates directly reduce the upfront cost the energy savings need to offset. Only include rebates that are confirmed and applicable to the specific equipment and program, since eligibility rules change frequently.
No. This report calculates a simple payback period using current utility rates held constant, which is a standard way to compare options but not a forecast. If the fuel being replaced gets more expensive faster than the fuel the new system uses, the payback period will improve, and if electricity prices climb faster, it will lengthen. Rate forecasts are inherently uncertain and outside the scope of this tool.
