Upfront cost is a major part of the ROI equation. Rebates, grants, and incentives can reduce net cost and shorten payback, but only if they are actually available to you.
Installed cost can vary by equipment choice, ductwork needs, and regional labour rates. If you only have a rough estimate, try a range to see how payback changes.
Checklist:
- Confirm which rebates you qualify for
- Use net cost after rebates
- Include any required upgrades
Keeping costs realistic improves the usefulness of the calculator output.
