4 to 5 Million A/Cs a Year, and Each One Locks Out a Heat Pump

Straight-cool air conditioners still make up more than half of U.S. shipments. That is 4 to 5 million units a year, or one every 6 to 8 seconds. Each one keeps that home from using heat pump heat for 10 to 20 years. The crossover in the headlines? It was mostly the R-410A destock, not homeowners — and now that the destock is over, straight-cool is back on top.

The Number That Should Bother Every Contractor

About 4 to 5 million straight-cool a/cs ship in the U.S. each year. That works out to one unit sold every 6 to 8 seconds. Every one blocks heat pump heating in that house for 10 to 20 years.

Here is what stings. Heat pumps outsold a/cs from September 2025 to January 2026. That was the crossover. Then it stalled. The heat pump share of shipments has flattened: 45.7% in the first eight months of 2025 and 45.5% over the same months this year. Straight-cool units still take more than half of everything that ships.

So what ended it? The article reports the crossover was mostly the R-410A destock, not homeowners switching. My read: once you see what actually moved the numbers, your replacement calls look different.

The Crossover Was a Warehouse Story

The 2025 drop came from distributors clearing R-410A stock, not from homeowners changing their minds. Distributors loaded up on R-410A units in 2024, cleared that stock in 2025 and quit reordering. Straight-cool shipments from July to December 2025 came in near 1.6 million, against about 2.5 million in a normal second half.

In September, Dave Gitlin, the CEO of Carrier, told investors the company was "no longer dealing with the destocking that affected results last year".

The heat pump tax credit from the federal government also ran out at the end of 2025, which likely moved some heat pump sales earlier.

The destock is finished, and straight-cool is back on top. My read: the real question is what decides whether a house gets a heat pump when the old unit fails.

The Vote Happens in the Basement

A furnace usually outlives the a/c, so the a/c tends to fail first, often while the furnace still has years left. Each dead a/c hands a vote to the homeowner and the contractor.

That vote is the whole game. My read: it is the moment your business either shows the choice or hides it.

When the entire system is due, the article says to pair the new furnace and a heat pump and offer at least one variable-speed, communicating model. Comfort beats single- or two-stage by a wide margin, and with the right products the price gap is narrower than it once was.

The hybrid also removes the objection the article calls the final excuse for a straight-cool a/c: that a heat pump cannot heat the house. With the furnace still in place, the heat pump does not need to carry the whole load.

My read: the money gap between the two quotes is smaller than many contractors assume.

The Price Gap Is Smaller Than You Think

Wholesale cost for the same model in a heat pump version runs roughly $300 to $1,000 more, covering the indoor and outdoor units. The install is not much harder. On a furnace that is dual-fuel ready and paired with the right thermostat, the thermostat handles the control wiring and the extra work often takes under an hour.

Yearly running costs come within $100 to $200 of gas-only, either way, as fuel prices shift. The homeowner can go with whichever fuel is cheaper in a given year. With propane or oil, hybrids almost always save money, sometimes a lot.

Comfort is not a theory. Steve Rogers, who works at The Energy Conservatory, cut his Minnesota home's heating gas use by 62% with a single-stage heat pump. Nate Adams, who wrote the article, has seen upwards of 80% for his own Cleveland clients when the heat pump carries the house as often as it can. Jim Bergmann of measureQuick put a hybrid in his own home and said: "I'll never go back to straight cooling again, ever."

There is one more angle, and your clients have heard the headlines about electric rates.

The Grid Math That Helps You Sell

RMI, once called Rocky Mountain Institute, reported in October 2026 that a blend of hybrid and all-electric homes could get roughly 65% more heat pumps onto today's winter grid than all-electric homes alone. It also found that this could cut household electric rates by roughly 13% on average from where they would otherwise land. Timing explains it. A hybrid can move to the furnace during the coldest hours, when demand on the grid peaks.

Programs can help here. Clay McCombe, who works with Power Ahead Colorado and was named an ACHR NEWS Top 40 Under 40 honoree this year, says most heat pump rebates in that program have gone to hybrid systems so far. When Vancouver, B.C. began requiring heat pumps in place of a/cs for existing homes starting in 2023, distributors there came to like it: carrying one product instead of two opened up warehouse space.

So the sale is on your schedule board now. My read: the question is whether your team is set up to ask for it.

What This Means for an Owner Who Sells

This part is my opinion, not the article's.

Picture an unnamed home services company with four trucks. A homeowner calls in July because the a/c died. Today the tech quotes a straight-cool replacement because it is quick and already on the truck. Under the hybrid approach, the tech quotes the heat pump version and leaves the furnace in place. The equipment line rises $300 to $1,000, the install often adds under an hour, and the homeowner gets quieter, steadier winter heat. My read: the average ticket goes up, the complaint that the new system feels just like the old one goes away, and your company becomes the one that explained the choice.

That case teaches the lesson. The choice gets made at the changeout, by the person standing there when the old unit quits.

How to Use This Week

1. Review recent replacement quotes. Sort them into straight replacement and upgrade presented. The second pile is your scoreboard.

1. Build one hybrid quote template. Same model, two lines: straight-cool, and the heat pump version with the furnace staying. Use the real gap, not a guess.

1. Train one sentence, not a pitch. The tech's job is to put two numbers in front of the homeowner and let them choose. A short script for a home services call: tell the homeowner the a/c is done and the furnace has years left; then offer the same system as before or the heat pump version with the furnace as backup. Ask if they want both priced.

1. Check whether hybrids qualify for rebates where you work. When local programs allow hybrids to qualify, contractors take advantage. Call your distributor and ask which local programs pay on a hybrid, then put that answer in the quote.

1. Add the ask to the phone script. Have the estimator ask one question before sending the estimate: whether the customer wants the upgrade option included so they can compare.

1. Track two numbers. How many replacements you quoted, and how many had an upgrade on the paper. That is the scoreboard that matters here.

Mistakes to Avoid

• Don't lead with electrification or policy. Most contractors the author knows don't care about it. Lead with comfort, keeping the furnace, and the built-in backup.
• Don't quote a whole new system when the furnace is fine. The whole advantage is that no working equipment gets thrown out.
• Don't assume the gap is huge. It is often smaller than the customer expects. My read: that is the point.
• Don't let fast win by default. The quickest replacement is another a/c, and that is exactly how a number goes flat.
