Methodology

How we rank programs

Each state's rankings weigh accreditation and state approval, alignment with that state's licensing pathway, total cost and resulting debt load, program length, schedule flexibility, EPA 608 preparation, and documented employer connections. Where a school publishes completion rates, placement rates, or graduate earnings, that transparency counts in its favour, because a program willing to show its outcomes is giving you something to check.

Union apprenticeships are included and ranked against the same criteria. They pay you to train, they charge no tuition, and they cannot pay us anything for placement. Leaving a free competitor off a ranking is how you spot a list built for schools rather than students, so ours are on it.

Where the figures come from

Licensing requirements, fees, experience rules, and renewal cycles come from the issuing authority's own published pages, cited on each state guide. Where two official sources disagree, or where a figure comes from a secondary source, the state page says so in plain language rather than picking a winner quietly.

Wage figures are the state median for HVAC mechanics and installers, occupation 49-9021, from the US Bureau of Labor Statistics OEWS May 2024 release. For Nevada, Utah, and South Carolina our current figure comes from an industry compilation of that release rather than the release itself, and those three pages label the figure an estimate rather than attributing it to BLS.

School costs and program lengths are drafted from published school and board sources. Every school entry carries its verification status. Content drafted but not yet checked against a primary source by a human is marked DRAFT.

What the payback calculator computes

One piece of arithmetic: the program cost divided by monthly gross pay at the figure in the pay field, giving the number of months of gross earnings equal to the cost. Nothing else. It does not model tax, take-home pay, living costs, financial aid, wage growth, overtime, or the probability of finishing the program, all of which change the real answer. It is a framing device, not a forecast.

Cost and length are pre-filled from the program's listing, and the note under the cost field states the basis: a published program total, a published annual figure multiplied by the program length, or no published total at all. Where a school publishes only a per-credit rate or no figure, the calculator asks you for the number rather than inventing one, because a total assembled from a per-credit rate and a guessed credit count would look precise and be wrong.

The pay field defaults to your state's median for experienced technicians, which is higher than entry pay. That default makes payback look faster than a first year actually is, so the field is editable and the page says to adjust it down. Every figure the calculator produces is gross, before tax.

What the state comparison does

It displays fields from two state guides side by side: license name, issuing body, experience requirement, fee summary, renewal cycle, and median wage. It performs no computation and reaches no conclusion about which state is better, because that depends on where you live and what you want to build. Fee entries are summaries; the full guides carry complete cost detail.

What we will not build

We do not offer a reciprocity checker, even though it is the most requested tool in this category. Reciprocity agreements change without notice, several boards decide case by case, and a wrong "yes, your license transfers" is the most expensive error a site like this could hand someone. Until that answer can be backed by board-confirmed data for every pair of states, the honest version is to read both states' pages and call the receiving board.

Independence

We may be compensated when someone submits an inquiry through a form on this site. Compensation does not affect rankings, and no school can pay for placement, position, or a badge. The apprenticeships we rank cannot compensate us at all, which is part of why they are included. If we ever accept direct placement money, this page will say so before the rankings change.

Requirements and prices change constantly. If you find something here that is out of date or wrong, the contact address in our Terms reaches a person.
