Equipment rankings
Equipment ranked on certified performance
One federal dataset, one published method, and a list of the things these rankings deliberately do not measure.
Written by HYRE HVAC Research Desk Primary-source research, data analysis and fact checking
The short answer
Every ranking here is ordered on one certified rating from US EPA ENERGY STAR data, and nothing else. HyreHVAC collapsed 281,975 certified combinations to 8,465 distinct outdoor units.
There is no "best overall" pick, because we hold no sourced data on price, reliability or warranty. If a list cannot state what it is ordered on, it does not ship.
Which equipment rankings are there?
What rules does every list here follow?
Each table states its metric in its own heading — coefficient of performance at 5°F, capacity retained at 5°F, HSPF2, SEER2, CEER. A reader can re-run any of them against the federal file and get our numbers back.
A federal row is a certified combination, not a machine. 281,975 rows contain 1,394 model numbers sold under more than one brand — one is sold under 17. The collapse from rows to families is described on every page that uses it.
Efficiency ratings scale with capacity and differ systematically between ducted and ductless equipment. Ranking across those categories manufactures a result. Capacity bands are the ordinary 12,000 Btu/h ton increments, which is a classification rather than an estimate.
No sourced data exists for those on this site, so no score for them exists on these pages. This is the single largest difference between what is here and what is on the pages that outrank it.
The AHRI Directory is the industry’s certification register and it is publicly browsable, but its terms prohibit its contents being reproduced or entered into a database for derivative use, and AHRI’s licensing FAQ answers this exact use case with "No".
Public browsability is not permission. We link to it as your verification step and copy nothing from it.
Why are these lists narrower than other “best” lists?
Because they rank only what can be measured. The commercial ranking pages in this category almost all present a single ordered list of ten manufacturers with a numeric score beside each.
That format requires the writer to hold comparable data on price, reliability, warranty performance and dealer network for every brand. Nobody publishes that data.
Where the score comes from instead is usually an affiliate table, occasionally a survey of the writer’s own opinion.
HyreHVAC analysis: the certification data supports a narrower claim very well and a broad claim not at all.
It can tell you, exactly and reproducibly, which certified outdoor units hold the most heating capacity at 5°F and which carry the highest seasonal ratings in a given capacity band.
It cannot tell you which brand’s compressors last longest, and there is no public dataset that can. So these pages answer the first question in detail and decline the second in writing.
The practical consequence for a reader is that a name near the top of one of these tables is evidence about a laboratory rating, not a recommendation to buy.
What decides the outcome in a real house is the load calculation, the ductwork, the commissioning and the installer — none of which is a property of the box.
Questions
What are these rankings based on?
Why is there no single "best heat pump" list?
Do you use the AHRI Directory?
Does a top ranking mean I should buy that unit?

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 September 28, 2026, and they are what we have actually published rather than what we intend to.
- 13
- studies published
- 12
- federal sources read and cited
- 8
- 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. 8 of our 13 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.

A rating is not an installation
The certified numbers describe a market. Your design temperature, your ductwork and your installer decide the result in one building.
