Terms of Use

What using RetrofitROI means

RetrofitROI's tools and written content are provided for personal, educational use to help you reason through a home-energy purchase decision. Using a tool does not create a contract, a quote, a financing offer, or a relationship with any contractor, lender, or utility. Nothing on the site is an offer to sell, finance, or install anything.

No warranty on results

Results are calculated from the inputs you provide using the formulas described on the methodology page. RetrofitROI does not guarantee that a result matches what you will actually pay, save, or qualify for, and is not liable for a decision made in reliance on a result from the site. Verify anything consequential, such as a contractor's actual quote, a lender's actual rate, or a program's actual eligibility rules, against the party providing it before acting on it.

Not financial, tax, or professional advice

RetrofitROI is not a financial advisor, a tax preparer, an engineer, or a contractor, and nothing on the site should be treated as personalized financial, tax, legal, or engineering advice. Where a decision has tax, legal, or safety consequences, consult a licensed professional in that area.

Acceptable use

You may not use automated tools to scrape or systematically extract site content beyond ordinary personal browsing, misrepresent a RetrofitROI result as a quote, an approval, or a professional assessment, or use the site in a way that disrupts its availability for other users.

Changes to the site and these terms

RetrofitROI may update its tools, methodology, or these terms as its sources and product scope evolve. A material change to a calculation method is reflected in that tool's stated methodology version. Continuing to use the site after a change means you accept the updated terms. Questions about these terms can be sent through the contact page.
