Where our data comes from

Every listing in this directory comes from a public record, and each school page links to the record it came from. We have not visited these schools and we do not rate them.

Right now the directory holds 1,479 program entries at 935 schools (1,021 from federal education data, 458 from the workforce training finder).

Sources

• NCES IPEDS Completions (2023-24, and 2022-23 for schools missing from the newer file). A school is listed when it reported conferring at least one award in HVAC and refrigeration maintenance technology (CIP code 47.0201). Source: nces.ed.gov/ipeds.
• NCES IPEDS Institutional Characteristics, 2024 directory. School name, address, phone, website. Schools no longer marked active are dropped.
• NCES IPEDS 2023-24 price data. Program-level tuition, fees, books, and length are only available for schools that report by program (mostly short career schools). For other schools we show nothing, or the school-wide in-state undergraduate tuition clearly labelled as school-wide.
• CareerOneStop Local Training Finder (U.S. Department of Labor). Adds training providers that the Workforce Innovation and Opportunity Act (WIOA) eligible-provider system lists but that were not in the IPEDS files.

What this data does not tell you

• The data lags. A school can have started, paused, or closed a program since the data year.
• A school appears because it reported awards, not because we checked that it is enrolling now.
• Short, non-federal-aid programs and many employer or union apprenticeships are not in federal education data and may be missing.
• We do not show accreditation, job placement, or earnings. Ask each school, and check accreditors such as HVAC Excellence or PAHRA directly.

Corrections

If you run a school and see an error, use the school page.
