* The summarized savings information may not accurately reflect actual savings achieved by the homeowner if all proposed suggestions are implemented. For example, Central Air, Heating, Programmable Thermostats, Seal & Insulate, Water Heaters and Windows, when implemented together will have interactive effects on energy bills so the savings information may be overstated. The Home Depot suggests consulting a home energy consultant if you would like to develop a more accurate way to calculate overall savings for your home. Summarized totals for all results may vary due to rounding. Several outputs are not immediately displayed to the user on each calculator (e.g., CO2 savings is not displayed for dishwashers, Energy Savings is not displayed for Showerheads) but these values are included in the summarized totals.
