Women in HVAC: How Many Technicians Are Women, and Who Works in the Trade (2026)

How many women in HVAC jobs are there?

About 15,100 in 2025, or 2.7% of the 561,000 people the Bureau of Labor Statistics counted as HVAC mechanics and installers. Because the count rests on a survey sample, the 90% confidence range runs from roughly 8,100 to 22,200.

What the 2.7% measures: The share of employed people whose main job is coded as heating, air conditioning, and refrigeration mechanics and installers (Census code 7315, SOC 49-9021) in the BLS Current Population Survey, a monthly household survey. It counts people, not jobs, includes the self-employed, and says nothing about license holders, apprentices in school, or office staff at HVAC companies (BLS definitions).

Women were 2.7% of employed HVAC mechanics and installers in 2025, against 47.1% of all employed people, according to BLS CPS table 11 for 2025. BLS publishes the share, not the count; multiplying 561,000 employed by 2.7% gives about 15,100 women. The 2011 equivalent is about 2,700 women out of 338,000.

The single-year figure is less precise than it looks. Using the BLS method for approximate standard errors (BLS, July 2026) with parameters borrowed from the installation, maintenance, and repair occupation group, the 2025 share has a standard error of about 0.75 points and a 90% confidence interval of 1.5% to 3.9%.

For an HVAC owner, this means a crew of 37 technicians would include one woman at the 2025 national rate; most small shops employ none, and a woman technician on staff is unusual enough that recruiting pages and trade groups notice.

Is the share of women rising, or is it survey noise?

Rising, slowly. A straight line fitted through 15 years of published shares climbs 0.11 points a year, from 0.97% in 2011 to 2.51% in 2025, and the 2011 to 2025 change of 1.9 points passes a 95% significance test. Single-year moves, such as 2024 to 2025, do not.

The fitted slope of 0.11 percentage points a year has a t statistic of 5.0 and accounts for 66% of the variance in the annual shares (R squared 0.66). The published share was 2.0% or below in every year from 2011 to 2021 and has been 2.3% or above in each year since 2022.

Comparing 2011 with 2025, two samples far enough apart to be independent under BLS guidance (more than 17 months), the 1.9-point increase divided by its combined standard error gives a z score of 2.17, above the 1.96 needed for 95% confidence.

Averaging three years at each end smooths the noise: the pooled share was 1.2% in 2011 to 2013 and 2.7% in 2023 to 2025, and the average implied number of women rose from about 4,300 a year to 14,200, a 3.3-fold increase while total HVAC employment grew 50.8%. Women still accounted for only 5.5% of the trade's employment growth between those periods.

HVAC ranks sixth from the bottom of 24 large trades for women

Pooled over 2023 to 2025, HVAC's 2.7% women's share sits in a cluster with power-line installers, plumbers and electricians, below carpenters and well below painters and building inspectors.

Electricians had a pooled 2023 to 2025 women's share of 3.1% and plumbers, pipefitters, and steamfitters 2.8%. Their fitted 2011 to 2025 increases were 0.084 and 0.111 points a year, close to HVAC's 0.11. None of the three building trades is pulling away from the others.

For owners, this means the HVAC trade is not losing women to electrical or plumbing work at a measurable rate; all three draw on the same small pool, and the shortage of technicians described in our HVAC technician shortage report is not being closed by any one group.

Hispanic workers account for about four in ten of the trade's added workers

The Hispanic or Latino share of HVAC mechanics and installers rose from 16.9% in 2011 to 26.7% in 2025, twice as fast as the all-worker share. The Black share rose from 5.8% to 10.4%. The Asian share is too small to read year by year.

Between the 2011 to 2013 and 2023 to 2025 averages, HVAC employment grew by about 180,000 people (from 354,000 to 534,000). Implied Hispanic or Latino HVAC workers grew by about 74,800 (from 59,000 to 133,900), which is 41.6% of the growth. Implied Black workers accounted for 15.2% of the growth.

The fitted rise in the Hispanic or Latino share of HVAC workers was 0.69 points a year from 2011 to 2025, against 0.34 points a year for all employed people, a ratio of 2.0. The Black share of HVAC workers rose a fitted 0.3 points a year. The White share, published only from 2017, fell from 90.6% in 2017 to 80.9% in 2025.

The Asian share of HVAC workers ranged from 0.7% (2023) to 4.4% (2025); the implied number of Asian HVAC workers is small, so these swings mostly reflect the sample. Pooled, it was 2.5% in 2011 to 2013 and 2.9% in 2023 to 2025, against 7.5% of all workers in 2025.

For an HVAC owner, the line that matters is that more than a quarter of the national technician workforce in 2025, 26.7%, was Hispanic or Latino, above the 20.0% share among all workers.

Is the HVAC workforce getting older? Not since 2021

The median HVAC mechanic or installer was 39.9 years old in 2025, 2.2 years younger than the median US worker (42.1). The median peaked at 41.9 in 2021 and has fallen since; across 2011 to 2025 there is no statistically clear trend.

The fitted change in HVAC median age from 2011 to 2025 is minus 0.06 years a year, with a t statistic of about minus 1.1, which is indistinguishable from no change. Electricians got younger, from a median of 41.5 in 2011 to 39.6 in 2025; plumbers went from 41.4 to 40.2.

In 2025, 40.3% of HVAC workers were under 35 and 18.7% were 55 or older. That gives 2.15 workers under 35 for every worker 55 and over, against 1.48 across all employed people. The ratio was at its low of 1.46 in 2021, when 22.5% of HVAC workers were 55 or older.

The 25 to 34 age group held 28.3% of HVAC workers in 2025, compared with 22.2% of all workers. For owners, the technician bench is younger than the US workforce; the aging story in HVAC is mostly about owners and senior staff, which technician-level data cannot show.

Numbers that circulate about HVAC workers, checked against BLS

Several widely repeated figures do not match the BLS household survey for the same period, mostly because they come from member surveys of owners or carry no table reference.

• A 2021 Philadelphia Inquirer article attributes an average HVAC worker age of 55 and a 9% female share to ACCA. BLS CPS for 2021 shows a median age of 41.9 and a women's share of 1.5%. We found no ACCA table behind either number.
• A 2020 ACHR News article cites BLS for women at 2 percent of HVAC employees. BLS CPS showed 1.5% for 2020 and 2019, within sampling error of that figure.
• HARDI reports that 53 percent of respondents to its 2024 contractor survey were nearing retirement age; 61 percent of respondents were owners or executives, so the survey describes owners, not technicians. HARDI's separate BLS-attributed figure, that 44% of HVACR installers and technicians are under 35, matches the CPS 2024 value of 44.4%.
• A StartBusinessByState tabulation of Census American Community Survey microdata puts women at 2.0% of HVAC workers in 2024, against 3.0% in the CPS for the same year. The two surveys use different samples and both carry sampling error; the gap is plausible for an occupation this small.

How the Current Population Survey counts an HVAC technician

The CPS asks households about each person's main job. That makes it the only federal series with 15 consistent years of gender, race, Hispanic origin and age for this occupation, at the cost of sampling error and occasional coding breaks.

The CPS counted 561,000 employed HVAC mechanics and installers in 2025. The Occupational Outlook Handbook lists 440,900 jobs for the same occupation in 2025, a gap of 120,100. The two are different measures: the handbook counts jobs, while the CPS counts people, by main job, from a household survey (BLS OOH).

• January 2011: occupations moved to the 2010 Census classification; BLS did not revise earlier years, which is why this series starts in 2011.
• January 2020: occupations moved to the 2018 Census classification. The HVAC title stayed the same, but the plumber line dropped pipelayers, so plumber figures before and after 2020 are not strictly comparable.
• 2025: an 11-month average, because October 2025 data were not collected during the federal government shutdown.
• BLS does not show a percentage when the base is under 50,000 people, which is why some small trades are missing from the ranking.

Summary

• Women were 2.7% of US HVAC mechanics and installers in 2025 (BLS CPS), about 15,100 of 561,000 people.
• The 2025 share has a 90% confidence interval of 1.5% to 3.9%, so single-year moves should not be read as trends.
• Over 15 years the share rose a fitted 0.11 points a year; the 2011 to 2025 change of 1.9 points is significant at 95% (z score 2.17).
• HVAC ranks sixth lowest of 24 large construction and repair trades for women, pooled 2023 to 2025, close to electricians (3.1%) and plumbers (2.8%).
• The Hispanic or Latino share rose from 16.9% (2011) to 26.7% (2025), and Hispanic workers accounted for 41.6% of the trade's employment growth.
• The median HVAC worker was 39.9 in 2025, below the all-worker 42.1, with 2.15 workers under 35 for every worker 55 and over.
• The workforce is not measurably aging: the median peaked at 41.9 in 2021, and the 2011 to 2025 fitted change is not statistically different from zero.

Data quality and exclusions

• 15 annual table 11 files and 15 table 11b files parsed; 0 HVAC cells were suppressed (BLS dash) in any year, so no year was dropped from the women's share series.
• The White column is not published in table 11 for 2011 to 2016 (6 years); those cells are left blank, not filled.
• 2011 to 2014 table 11 values were parsed from HTML (thousands separators removed); 2015 to 2025 from XLSX.
• Before 2020 BLS published 'Pipelayers, plumbers, pipefitters, and steamfitters' as one line; we used it as the plumber series for 2011 to 2019 and flag the break.
• Trade ranking: of the detailed construction and installation, maintenance, and repair lines in the 2025 table, we kept 24 with 100,000+ employed and a published share in all three years, excluding supervisor, 'other' and 'miscellaneous' lines.
• No values were imputed. Where BLS shows a dash (base under 50,000) the cell stays empty.

Methodology

Selection: we used the BLS Current Population Survey annual-average tables 11 (sex, race, Hispanic origin) and 11b (age) for every year from 2011, the first year of the 2010 occupation classification, to 2025, the latest release. Each year was downloaded from BLS (2011 to 2014 table 11 as HTML; all other files as XLSX) and parsed by script.

Inclusion: the occupation line 'Heating, air conditioning, and refrigeration mechanics and installers' in every year, with electricians, plumbers (pipelayers included before 2020) and all employed people for comparison. For the trade ranking we kept detailed construction and installation, maintenance, and repair occupations with at least 100,000 employed in 2025 and a published women's share in 2023, 2024 and 2025.

Conflicting numbers: where trade press or association material disagrees with the CPS, we report both and explain the difference in measure; we do not average sources.

Derived metrics: implied counts multiply the published employment level by the published share. Trends are ordinary least squares fits on 15 annual values. Standard errors follow BLS instructions (July 2026) for borrowing generalized variance parameters, using the PF-13 parameters for the installation, maintenance, and repair group and the CPS civilian noninstitutional population. Pooled shares weight each year by its employment.

Limitations: CPS estimates for an occupation of about half a million people carry sampling error; 2025 is an 11-month average; occupational coding changed in 2020; shares describe employed people, not license holders or business owners.
