Heat pump installation has to become more affordable to make adoption more compelling in the US, but in the meantime, there are ways to mitigate that cost.
Researchers at the US Department of Energy’s National Renewable Energy Laboratory (NREL) just published a paper in the journal Joule titled, “Heat pumps for all? Distributions of the costs and benefits of residential air-source heat pumps in the United States.”
The study quantifies the costs and benefits of air-source heat pumps across the US. The researchers based their conclusions on simulations of 550,000 statistically representative households. It considers climate, heating sources, and types of homes, as well as the performance of different heat pumps and whether insulation was upgraded.
Their analysis revealed a majority of Americans – 62% to 95% of households, depending upon heat pump efficiency – using a heat pump would see a drop in their energy bills. And if the home was weatherized, the range bumped up to 82% to 97%.
Nationally, heat pumps would cut home energy use by 31% to 47%, depending on their efficiency level, and 41% to 52% when combined with weatherization. (The big difference between energy savings and energy cost savings is that natural gas prices are much lower than electricity prices on a BTU basis in many parts of the US.)
The study found that heating fuel type and whether the house had air conditioning significantly impacted savings. For the 49 million homes that use electricity, fuel oil, or propane for heat and have AC, 92-100% of homes would see energy bill savings, with median savings of $300-650 a year depending on heat pump efficiency. They found that savings were most significant in colder climates.
But here lies the rub: Heat pumps may only be financially feasible for a smaller portion of households due to high installation costs. (The American Society of Home Inspectors says that the average heat pump installation cost is $5,500.) Plus, the researchers noted that installers without heat pump experience may charge higher prices.
The NREL’s Eric Wilson, lead author of the study, said it showed that there are millions of households “for whom the technology is still pretty expensive, and we need work to bring down the cost of installing heat pumps.”
But there are ways to mitigate that installation cost until installation prices drop.
There are Inflation Reduction Act rebates and tax credits to be had right now for heat pumps, as nonprofit Rewiring America explains:
For low-income households (under 80% of area median income), the Electrification Rebates cover 100% of your heat pump costs up to $8,000. For moderate-income households (between 80% and 150% of area median income), the Electrification Rebates cover 50% of your heat pump costs up to $8,000.
Plus, households get a 30% tax credit for heat pumps and heat pump water heaters, capped at $2,000 per year, and that can be combined with rebates.
And co-author Prateek Munankarmi said that homeowners could “save thousands of dollars on average” by installing a smaller heat pump if they first improve their houses’ energy efficiency, and there are good rebates and tax credits for weatherization, too.

VinFast delivered its first VF9 vehicles to customers in Los Angeles yesterday, kicking off US deliveries of the new 3-row electric SUV.
VinFast is a relatively new EV brand, founded in Vietnam in 2017, under the umbrella of massive Vietnamese conglomerate Vingroup. It started delivering cars to the US in 2023 with its VF8 mid-size SUV.
The VF9 is its three-row large SUV, which has been delivering in Vietnam since the 2023 model year, and also in some other Southeast Asian and a few European markets. But now it’s ready to start delivering the VF9 here in the US, and it started last night in Los Angeles.
VinFast held a small event at its US headquarters in Los Angeles to deliver the first 8 VF9s to the US market, and invited us out to the event and to have a quick look at the car.
VinFast told us that it currently has 36 dealerships in 15 states, with 13 company owned stores in California. So deliveries won’t just start right away in California, but other territories as well. However, VinFast couldn’t provide us an estimate of what the delay before delivery would be if ordering a vehicle today.
VinFast trim levels
The VF9 comes in two trim levels, Eco and Plus. The Eco model starts at $69,800 with the Plus version $4k more at $73,800. First deliveries will start with the Plus model, with the Eco coming a few months later.
But despite those somewhat high starting prices, VinFast is also offering a limited-time promotion for the first 100 vehicle deliveries to lease the Plus for $529/mo with $2,000 down. And since the VF8 has seen some really great lease deals, we could imagine the VF9 might get the same treatment after deliveries start happening in earnest.
The trim levels don’t differ significantly in drive capabilities, with the same battery and motor between the two. See the full spec sheet here.
The main differences are in a bunch of additional interior comforts on the Plus, like ventilated massaging seats, 2nd row seat heaters, seat and steering wheel position memory, rear LCD display, panoramic roof and a subwoofer. The Plus also has fog lights and cornering lights.
However, the Plus also has lower range at 291 miles instead of 330 miles, primarily due to larger 21in wheels compared to the base 20in wheels. Wheels can make a huge difference in aerodynamic efficiency, especially with different wheel cover designs.
The Plus is also about 100lbs heavier than the Eco, and can come in a 6-seat “captain’s chair” configuration, whereas the Eco only comes in a 7-seat layout.
Extremely quick first drive
We got a chance to drive the VF9 very briefly, but given that it was in the middle of LA rush hour traffic and only a few miles, this barely even qualifies for “first drive” status.
However, the vehicle felt quite spacious inside – as one would expect from a large SUV. We only sat in the seats for a few minutes, but the seat material was passably comfortable (not like the outstandingly comfortable EX90). The third row has a huge amount of headroom, but little legroom – you’re basically sitting on the floor back there, and it takes some work to get out of it, too.
The drive software does seem to have matured compared to the previous VF8 version I drove. That VF8 had horrendous throttle lag, especially when starting from 0mph, but I didn’t experience that quite so much here in the VF9. It felt better. They’re making progress.
The throttle pedal is a little weirdly jumpy though in sport mode, so despite that I set almost all EVs to sport mode and just leave it there, this might be a car that I’d drive in standard or eco more often. And hope that Vinfast continues to tweak the drive software to make it feel a little more refined. But that said, again, I’d like a chance to test this more and get a feel for it.
Power was good though not amazing, it’s a large car after all so comfort is going to be more of a premium than speed.
I like VinFast’s user interface well enough – it’s pretty well laid out, it doesn’t suffer from the lag that some other UIs do, and you can always escape to CarPlay or Android Auto if that’s your preference. Though the gathered media did experience some random faults on the 3 early-production press cars we had access to for the night, like a faulty anti-window-pinch sensor and rear hatch closure sensor.
All in all, after the relatively poor overall reviews for the VF8 and a middling experience myself when I drove one, I came away pleasantly surprised by the VF9, with a vehicle that was nicer than I expected on this very short drive. I’m still not a large SUV guy and would love to see some of VinFast’s smaller vehicles here (the VF7 is coming to the US, but I’d like to see the even-smaller ones), but as long as the arrow keeps going in the right direction and VinFast keeps improving, there could be a nice future here for Vietnam.
And that’s the thing… I really want VinFast to succeed. I like the idea of having another country join the international stage of auto manufacturing, and it would be great for Vietnam to gain some chops in the realm of complex manufacturing. The country already does well in textiles and electronics… but cars are a whole different thing. This drive was too short to draw many conclusions, but VinFast does seem to be improving from the short experience we had.

Crude oil futures edged slightly lower on Tuesday, after rallying about 3% in the prior session on fears that the war between Ukraine and Russia is escalating.
President Joe Biden has authorized Ukraine to use long-range missiles to hit targets in Russia in a major departure from Washington’s previous position, according to media reports.
China’s Xiaomi has reported a 30.5% growth in third-quarter revenue for its EV business, with the company also bumping up its yearly delivery target for the SU7 series EVs to 130,000 units.
Back in May, Xiaomi – the world’s third-largest smartphone maker – had said that it planned to build 100,000 EVs by the end of the year, with the company well on its way to achieving that goal. CEO Lei Jun said on his social media account that the company was bumping up its previous target of 120,000 of its first EV as “demand surges,” reports Reuters.
Last December, Xiaomi debuted its first vehicle, the SU7, which officially launched in March, offering three versions – Standard, Pro, and Max, with the Standard starting at $30,761 – strategically about $4,000 cheaper than the price of Tesla’s Model 3 in China. A souped-up hypercar version, the Ultra, has also since been unveiled.

Since its launch, the SU7 has been a hit in China and is set to easily surpass production goals of 100,000 units one month early. To boost that momentum, Xiaomi now expects to complete the construction of an expansion of its EV factory in mid-2025, which should ramp up its numbers even more – at least, that’s the aim.
In the third quarter of this year, Xiaomi has said that it delivered 39,790 units of the SU7, for a total sales figure from its March launch to the end of September to 67,157 units.
Huatai Securities has forecast Xiaomi will deliver 400,000 EVs in 2025, with its EV business accounting for about a fifth of its revenue compared with 8% this year, Reuters reports.
Of course, analysts have predicted the company would lose money on its SU7, to the tune of around $10,000 a vehicle, but the smartphone maker has a tidy cash reserve of $15 billion to help it weather the storm.

While facing plenty of competition in China from the likes of BYD, the company has, for one, tremendous brand appeal to the Chinese consumer, who are already familiar with its products and user interfaces. In addition to an alluring price point, the SU7 is a connected car that syncs with other devices. Compared to other EV makers, Xiaomi, too, has an edge on software and a jumpstart on autonomous driving, which it has been testing on roads for a few years.
The company says it plans to invest $10 billion over the next 10 years in building its EV empire, reports have said. By the end of the year, the company expects to expand to 22 sales stores, 135 service centers, and 53 delivery hubs in 59 cities.
