Direct answer
If something on this site is wrong, tell us and we will fix it. Substantive corrections are disclosed on the page itself, with a dated note saying what was wrong and what it now says. We do not quietly edit an error out of existence. Typographical fixes are made silently; anything that changes the meaning of a claim is not.
How to report an error
Use the contact page. The most useful report includes:
- The page address and, if you can, the sentence or figure in question.
- What you believe is wrong about it.
- Any source that shows the correct position, if you have one. This is genuinely helpful but not required.
You do not need credentials to report an error and we do not weight reports by who sent them. A homeowner noticing that a number contradicts another page is doing exactly the job this policy exists for. If you work in the trade and something we wrote is wrong in a way only a technician would catch, that is the most valuable report we can receive, since nobody here has field experience.
What happens next
- We check it against the source. Every claim on the site is tied to a named source with a date, so the first step is opening that source and reading the passage again. If the source has changed since we cited it, that is itself the finding.
- We decide what kind of error it is. The categories are below, and the category determines how the fix is handled.
- We fix it, and we fix it everywhere. Figures on this site are reused across pages. A correction to a cost figure is applied to the cost guide, the calculator, the facts reference, and anywhere else it appears, in the same edit.
- We reply. If you left a way to reach you, we will tell you what we found, including when we conclude the original was right. Disagreement is a legitimate outcome and we will explain the reasoning rather than just declining.
We aim to acknowledge reports promptly and to correct clear factual errors quickly. A report that requires re-tracing a source lineage takes longer, because doing it properly takes longer.
How corrections are marked
| Kind of change | How it is handled |
|---|---|
| Typographical and formatting | Spelling, punctuation, a broken link, a table that renders badly. Fixed silently. The meaning does not change, so a note would be noise. |
| Substantive correction | A wrong figure, a misattributed source, a misstated position, a date error, or anything that changes what a reader would conclude. Fixed and disclosed with a dated correction note on the page saying what was wrong and what it now says. The note stays permanently. |
| Clarification | The original was accurate but could be read the wrong way. Rewritten, with a dated note explaining what was clarified where the ambiguity was material. |
| Update | The facts changed rather than us being wrong: a source published new figures, an enforcement action concluded, an agency revised its guidance. The page is updated and its last-updated date changes. This is not a correction and is not labeled as one. |
| Retraction | A claim we should not have published at all. The claim is removed and a note explains what was removed and why. We do not delete the page to make the problem disappear. |
The commitment
A substantive correction is disclosed, not silently edited. That is the whole point of this page and it is worth stating without hedging.
The reasoning is simple. This site asks you to trust its figures on the strength of its sourcing. A publication that fixes errors invisibly is asking for that trust while removing the only evidence you could use to calibrate it. Every visible correction on this site tells you something true about how carefully the rest was done, which is why we would rather carry the notes than look flawless.
The same logic governs dates. We do not refresh a “last reviewed” date to make a page look current; that date changes only when someone actually reopened the sources. That rule is set out in full in the editorial policy.
Corrections we have made
None yet. This site published on August 15, 2026, and any corrections issued after that date will be noted on the pages they affect.
What is not a correction
Two things we get asked about and treat differently.
Disagreement with our conclusions. Our editorial position is that most homes do not need routine duct cleaning, and we reach it from U.S. Environmental Protection Agency (EPA) guidance rather than from a preference. If you think the reasoning is wrong, we will engage with that, and if the argument holds we will change the page and say why. But a conclusion you dislike is not automatically an error, and we will not soften a sourced position because someone in the industry objects to it.
Requests to remove accurate reporting. The enforcement record we cite comes from attorney general filings, court complaints, and published investigations. We will correct any detail we have got wrong about any case, immediately. We will not remove accurate, sourced descriptions of documented proceedings.
