The job outlook for HVAC technicians is strong in the federal data: BLS projects employment of HVACR mechanics and installers to grow 10.9% from 2025 to 2035 — much faster than the average for all occupations — with about 40,600 openings a year, many from replacing workers who retire or change occupations.
Below: what the projections say, whether the shortage story holds, how the trade handles recessions, and what will drive demand.
What does BLS project for HVAC jobs?
The headline projection: the Bureau of Labor Statistics expects employment of heating, air conditioning, and refrigeration mechanics and installers (SOC 49-9021) to grow 10.9% from 2025 to 2035, from 440.9k to 489.1k jobs — a count that includes the self-employed.
BLS's Occupational Outlook Handbook calls that "much faster than the average for all occupations"; the all-occupation benchmark is 3.5%.
On top of that growth, the occupation is projected to have about 40,600 openings a year, many from replacing workers who retire or change occupations — which is why annual hiring runs far ahead of the net growth in positions.
Date-stamp any outlook you read, because most pages online are stale.
These projections were released on August 27, 2026 and cover 2025 to 2035, superseding the older 2024–34 series; the May 2025 wage data, released May 15, 2026, likewise supersedes the widely quoted May 2024 figures.
A page citing the old series or the old medians is citing the previous release.
The base today: 409,670 wage-and-salary jobs in May 2025 — a payroll count that excludes the self-employed, which is why the projections show a larger 440.9k.
For orientation, the neighboring building trades project 6.8% growth over the same decade for plumbers, pipefitters, and steamfitters and 9.2% for electricians.
Our HVAC industry statistics page puts these projections next to the pay, geography and live hiring data for both trades.
Pay context for those jobs: the median wage was $29.33 an hour ($61,010 a year) in May 2025, the mean was $64,780, and the middle half of the occupation earned between $23.25 and $37.05 an hour.

Is there really an HVAC technician shortage?
Start with what the federal data does and does not measure: BLS publishes projections and openings, not a shortage statistic.
No federal number establishes a shortfall of HVAC technicians, and our research found none worth quoting — so treat any specific "X thousand techs short" figure as unsourced unless it names a methodology.
What the data does show is a hiring need that runs year after year: about 40,600 openings annually, many from replacing workers who retire or change occupations.
The replacement pressure has a real base.
In the 2025 household survey (a count that includes the self-employed), about 105,000 of 561,000 employed HVACR mechanics — 19% — were 55 or older.
A fifth of the workforce at or near the common retirement age is a genuine replacement task for the trade, whatever word you put on it.
The popular aging-workforce story, though, oversells it.
The median age of employed HVACR mechanics was 39.9 in 2025 — below the 42.1 median for all U.S. workers, and in line with electricians at 39.6.
The trade is not older than the workforce around it, and the "average tech is over 50" claims circulating online do not match the federal data.
One more structural piece: the trade recruits from a narrow slice of the labor pool.
Women were 2.7% of employed HVACR mechanics and installers in 2025, against 3.1% of plumbers, pipefitters, and steamfitters and 3.5% of electricians.
The honest verdict: tens of thousands of openings a year, a fifth of the current workforce in the 55-plus bracket, and a labor pool that recruits narrowly — but no federal shortage number.
"Shortage" is shorthand for the openings data, not a statistic of its own.
Is HVAC recession-proof?
Honesty first: no trade gets a recession guarantee.
BLS's projections are decade averages, not forecasts of the next downturn, and our research did not surface a federal statistic that measures how HVAC employment behaves in recessions — so this section sticks to what the numbers do support.
What the data supports is the demand mix: BLS attributes HVAC growth to construction and to retrofit and replacement work on existing systems, so a defined part of the trade's work is servicing and replacing equipment that already stands in occupied buildings.
The honest limit: part of the trade is tied to construction.
BLS names commercial and residential construction as growth drivers, and construction is the classic cyclical sector, so the new-construction slice of demand is the part that moves with the economy.
"Recession-resistant" is the defensible phrase; "recession-proof" is a slogan.
The service-and-replacement core is the part with the strongest claim to steady work in a downturn.
Is HVAC a dying trade?
The federal data points the opposite way.
HVAC is projected to be the fastest-growing of the big three building trades from 2025 to 2035 — 10.9%, against 6.8% for plumbers, pipefitters, and steamfitters and 9.2% for electricians — with employment rising from 440.9k to 489.1k jobs.
A dying trade does not post the fastest projected growth in its class.
The worry behind the question usually has two parts.
The first is automation: smarter diagnostics and computerized controls keep changing what technicians do, and whether AI will replace HVAC techs is a fair question to ask before training for any trade.
The visible reality of the job: the core work — installs, repairs, refrigerant handling — happens at the building, with tools in hand.
The second part is the technology transition itself, and it cuts toward more work, not less: the refrigerant rules now reshaping the equipment stock are a demand driver in their own right.
The next section takes the drivers in order.
What will drive HVAC demand: heat pumps, refrigerants, data centers
BLS names its drivers directly: commercial construction, including data centers, and residential building construction are expected to drive employment growth, along with more sophisticated climate-control systems and retrofit and replacement work.
Here is what each means for the outlook.
Data centers are the sharpest edge of the commercial story: server halls need cooling that never goes down, and BLS folds them into its commercial construction driver.
The niche has its own demands — redundancy, shift work, critical-facilities discipline — covered in our guide to data center HVAC work.
Heat pumps are the residential wildcard.
The installed base is real: in the Energy Information Administration's 2020 Residential Energy Consumption Survey, 16.13 million of 123.53 million U.S. homes — 13% — used a ducted heat pump as their main heating equipment, and another 1.06 million used a ductless mini-split, with 12.52 million of the ducted heat-pump homes in the South.
What BLS's driver list does not do is name heat pumps specifically — the residential driver is construction and replacement work generally.
And the federal policy tailwind has lapsed: the 25C Energy Efficient Home Improvement Credit, worth 30% of cost up to $2,000 per year for qualified heat pumps, applied only to improvements made through December 31, 2025 and is not available for 2026 installs — so discount any page still advertising it as a current incentive.
Refrigerants are the quiet driver, and the one already underway.
Since January 1, 2025, new residential and light-commercial AC and heat-pump systems may not be installed with refrigerant of GWP 700 or more (with an exception for systems whose specified components were all made before that date), and self-contained products face the same limit at manufacture.
The AIM Act's HFC phase-down keeps stepping the supply down: capped at 60% of baseline in 2024–2028, 30% in 2029–2033, 20% in 2034–2035 and 15% from 2036.
Existing systems stay serviceable for their whole useful life, so both sides — new low-GWP installs and the old stock's service calls — are work.
Our guide to the A2L refrigerant transition covers what changes for techs.
Which segments are growing fastest?
BLS projects the occupation as a whole and publishes no segment-level growth table for HVAC — so the honest answer maps the named drivers onto where the jobs and the pay actually sit.
By employer, this is contractor-land: building equipment contractors employed 305,330 of the occupation's 409,670 wage-and-salary workers in May 2025, and the next-largest industries BLS itemizes are merchant wholesalers of durable goods (12,190 jobs) and fuel dealers (8,480).
By demand driver, the growth segments BLS names are commercial construction — data centers included — residential construction, and retrofit and replacement work on existing systems.
The pay map shows where the niches are, with the caveat that high pay is not high volume.
The highest-paying industries for the occupation in May 2025 were computer systems design and related services (median $115,910), scheduled air transportation ($114,080) and natural gas distribution ($105,630) — small niches, not typical jobs.
Geographically, the most jobs were in Florida (39,160), California (35,130), Texas (34,730), New York (24,430) and Pennsylvania (15,880), and the largest metro job centers were New York-Newark-Jersey City (21,820), Dallas-Fort Worth (10,910), Los Angeles-Long Beach-Anaheim (10,720), Miami-Fort Lauderdale-West Palm Beach (9,140) and Washington-Arlington-Alexandria (8,730).
The highest-paying metros were different places again — Fairbanks-College ($93,820), Anchorage ($85,620), Napa ($84,570), San Jose-Sunnyvale-Santa Clara ($82,050) and Seattle-Tacoma-Bellevue ($80,100) by annual median — so weigh volume against pay for your own move.
Where does that leave a person deciding?
The demand data answers "is the trade growing" — it is, faster than the trades around it.
Whether it is the right trade for you is a separate question: our page on is HVAC a good career weighs the honest pros and cons, and our HVAC technician guide covers the role itself, day to day.
