The HVAC industry is short 110,000 technicians. Every one of them feels absent right now.

It's mid-June. Your phone is ringing. NOAA is forecasting a hotter-than-normal summer. The shipment data just turned positive for the third month running. Everything points to a busy season — except the one thing you need to deliver it: people.

The technician shortage isn't a new story. It's been building for a decade. This summer, it's the operational constraint that determines whether your business has a good year or a brutal one.

The Numbers

The industry is short an estimated 110,000 technicians nationwide, with the number of certified techs dropping 50% over the past decade. The BLS projects roughly 42,500 HVAC job openings per year — not from growth alone, but because 25,000 techs leave the workforce every year through retirement and burnout. Over 50% of working technicians are over 45. The pipeline behind them isn't large enough to absorb that retirement wave.

A2L has added a new layer on top. Every technician entering the field today needs documented training on mildly flammable refrigerant handling, safety protocols, and leak detection procedures that didn't exist three years ago. A tech who spent a decade on R-410A equipment isn't automatically qualified on A2L systems. That's a skills gap sitting inside the labor gap.

Why This Summer Is Different

The 2025 market correction gave contractors a cushion. Call volumes were down, crews weren't stretched, some shops quietly reduced headcount. That cushion is gone. Shipments have turned positive, HARDI distributor sales are up 4.5% in April, and NOAA is forecasting above-normal temperatures through September. If pent-up replacement demand starts converting this summer, you'll feel the capacity constraint immediately.

Emergency hiring in July costs more than planned hiring in April. Overtime during a heatwave costs more than a salaried technician in February. Every shop that ran lean through the correction is now competing for the same small pool of available techs.

The Capital Is Coming — But Not This Summer

This week brought major commitments to skilled trades training. Google announced $50 million to prepare more than 300,000 workers for trades including HVAC. Bloomberg Philanthropies launched a $90 million National Skilled Trades Initiative on June 8. BlackRock's $100 million Future Builders program opened a $25 million grant RFP this month. Combined with a $250 million Lowe's Foundation commitment in April, capital pledged to skilled trades development in 2026 alone has crossed $555 million.

None of that fills a shift this August. A student who enters an apprenticeship this fall won't be on a service truck until 2028. The commitments matter for the long-term structure of the workforce. They don't solve this season.

What You Can Do Right Now

Get A2L training current. A tech who isn't documented as A2L-trained is a tech you can't deploy on a full category of calls. ACCA and multiple manufacturer programs offer the training. Do it now, not after you lose a job.

Cross-train your installers for service. A technician who can flex between install and service gives you scheduling options a single-track crew doesn't. Build that flexibility before the heatwave hits.

Stop waiting to hire helpers. You don't need a fully certified tech to ride along and free up your senior technician for diagnostic work. A helper hired now is productive by July. One hired in July is still learning in September.

Look at your compensation. Experienced technicians are earning median wages closer to $90,000 in current market conditions. If you're pricing labor on 2023 rate cards, you're going to lose people to shops that aren't.

The Bottom Line

The shortage isn't coming. It's here. The contractors who didn't cut too deep into their bench during the 2025 correction are in a strong position. The ones who ran lean are going to spend the next three months making the most expensive hiring decisions of the year.

The industry's pipeline problem won't be solved by $555 million in philanthropic pledges — not this summer. It gets solved on the shop floor, one trained technician at a time, by contractors who treat workforce development as a capital investment rather than an HR expense.

The shops that figure that out first are the ones still growing in 2028.
