HVAC cost methodology
The bar a price must clear before it appears on this site, and an honest note on where we stand.
Written by HYRE HVAC Research Desk Primary-source research, data analysis and fact checking
The short version
Our HVAC cost methodology sets one rule: a price appears only when at least 12 sourced, dated quotes back that exact cell, and we never scale a national figure down to a state or job.
As of October 26, 2026, no cost cell has cleared that bar. That is why HyreHVAC publishes no HVAC prices and our calculators ask you to type in your own figures.
What is a cost cell, and what must it have?
A cost cell is one price for one job in one place: for example, a like-for-like furnace replacement in one state.
Before we publish a figure in a cell, it needs at least 12 quotes or invoices for that job.
Each must be sourced and dated, so a reader could in principle check where it came from.
We never interpolate. A national average divided down to a state is not evidence about that state. A cell that falls short stays blank, and the page says why.
What does not count as evidence
They gather quotes from contractors who buy leads. Useful context, not audited job prices.
A guess dressed as data.
Prices move. A figure with no date cannot be checked.
We do not install equipment, so we have no job data of our own.
Where does the evidence stand?
| Item | Status on October 26, 2026 |
|---|---|
| Cost cells with 12 or more sourced, dated quotes | None |
| Prices published on HyreHVAC | None |
| Calculators with default dollar rates | None in new tools; you type your own figures |
| Federal 25C tax credit in our maths | Counted as nothing: it does not apply to systems placed in service after December 31, 2025 |
What do we publish instead?
We explain what drives the price of each job on our HVAC cost guides page.
Our calculators, such as the HVAC cost of ownership calculator and the HVAC quote checker, work from figures you enter from your own quotes.
Non-price numbers, such as equipment life and efficiency rules, come from named public sources and are dated.
How would this change?
When a cell reaches the bar, the page that covers it will show the figure, the number of quotes, the date range and the source types. If you have dated invoices you are willing to share, see corrections for how to reach us. We will not publish a figure from fewer.

HYRE HVAC Research Desk
Primary-source research, data analysis and fact checking
We are a research desk, not a sales floor. We read the federal microdata file, the statute or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify.
The counts below are generated from the published pages themselves, last counted October 26, 2026, and they are what we have actually published rather than what we intend to.
- 18
- studies published
- 15
- federal sources read and cited
- 15
- studies published with their full dataset as CSV
- 51
- jurisdictions reproduced against EIA’s own tables
How this desk works
- Primary sources only. Federal data comes from the agency that collects it, in the file that agency publishes. We do not cite an article that cites a source; we download the source and compute the figure ourselves.
- We validate against the agency before we publish. First, we use each federal microdata file to reproduce the agency’s own published tables. Our cooling research reproduces EIA’s state estimates and standard errors for all 51 jurisdictions. That check caught a variance formula that was off by a factor of four.
- Every estimate carries its uncertainty. These are survey figures, not counts. Standard errors are computed from the replicate weights the federal file supplies and printed beside the estimate. An estimate too imprecise to publish is reported as such rather than printed.
- Nothing is typed by hand. Prose, tables and charts all read from one dataset built by script, so a number in a sentence and the same number in the table below it cannot disagree.
- We publish the data, not just the conclusion. 15 of our 18 studies offer the full computed table as a CSV download on the page, so you can check the analysis or disagree with it. A study without a row-level dataset gets no download link and claims none in its structured data.
- We correct in public. Where we have published a figure wrongly we fix the figure, rewrite any analysis that rested on it rather than patching the number underneath it, and leave a dated correction note on the page.
- We do not install or sell HVAC equipment, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Data as of Sources checked October 26, 2026. Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
Sources & retrieval dates
HyreHVAC is a publisher. We do not install, repair or inspect HVAC equipment and hold no contractor licence. Nothing here replaces an on-site diagnosis by a licensed contractor. Sources are cited with the date they were checked.
