Questions, corrections, and feedback are welcome, especially anything that makes the estimates more accurate or the explanations clearer.
Write to [email protected]. If your question is about a specific estimate, use the "Copy result link" button on the calculator and include that link: it contains your inputs, so we can see exactly what you calculated.
What we can and cannot help with
We can explain how the calculator works, fix errors, and improve the guides. We cannot recommend a specific brand or model, quote installation work, or advise on electrical and gas code questions: those belong with a licensed local professional.
