Yes! Heat pumps do both heating and air conditioning from one system! It’s a common misconception that they only heat - they do cooling too!

020

But you’re also paying for the health safety inspection, the food safety trainings, the proper refrigeration of the ingredients, and a whole load of other things. Plus, you know that restaurant will be there tomorrow so you can keep getting tacos for years to come.

000

When you think about the cost of a qualified, licensed contractor, it’s just like the restaurant. Sure, you’re paying for the taco.

100

Working with an unlicensed contractor is a lot like buying street food. It’s cheaper than the nice restaurant, sometimes it’s really good, but sometimes it tastes better going in than coming out.

This plate of tacos cost me $4 And it might give me diarrhea…

Replace central air with central heat pump!

Thank you to Matthew at Laminar Collective for showing me around their test lab! Cool stuff brewing from our friends on the other coast to help us get more heat pumps in more homes!

Caption this (Seriously though, Sara and I had an awesome time at the US Heat Pump Summit, I'll pull together a bigger brain dump soon)

Every message like this is one less gas appliance polluting for the next two decades. This is how we electrify - one house at a time. Grateful for the partnership with the awesome team at @volthub.bsky.social for their support in the California Heat Pump Group Buy!

Rebate programs come and go & a big one in the LA area just came back. In <1 week more than half the funds have already been claimed! So we sent out a frantic email monday night helping all of our @vayu.pro LA customers jump on it. If you want a heat pump in LA, this might be your moment!

It's by far the majority of the HVAC market in the US! While it's a bummer we can't serve every single person with this, we're going for the 80/20 rule

We've been getting a ton of demand in San Diego so I think it's quite likely!

Shreyas Sudhakar @shreyassudhakar.com · 02/09/2026

there's a ton of local AC to Heat Pump ordinances coming around which I'm really excited about!

130

Will I see you at the Heat Pump Summit? I'm excited to join some really smart people (Eric at Amply, Piers at SeeAir) in a panel about tech-enabled heat pump business models. Some secret sauce might come out, so you'll have to join us in person to get the scoop! PS: use code SS26 to save on tix!

We're not the best fit for every project, but it's still so gratifying to get feedback like this from @vayu.pro customers!

Because speed and scale alone is where you start hearing people say that "solar salesmen are sleazeballs" and "I paid $30k for solar and half of the micro inverters fried 2 months in and they won't return my calls" (7/7)

Once we've really nailed that (I think we're getting super close), we'll pour gas on the fire. But only then, and if our outcomes or quality ever stop dropping we'll take a beat before we keep going. (6/almost done)

100

I've actually installed fewer heat pumps in the last two years than I did my first two years. And it's a good thing! We've been diving deep into what makes a quality system and a quality customer outcome. Each of our installs is better than the last one, and we're learning so much. (5/a bunch)

The ugly truth is that we can't simply focus on the number of systems installed. Solar 1.0 is a great example of this. They focused on speed and scale over customer outcomes, and yelp reviews tell the story better than I could. (4/many)

100

And it's true! At the rate I've been averaging, it'll take me 60,000 years to replace every single gas furnace in SF. And probably a few hundred million more to replace all of them in California. (3/many)

The other day one of my teammates was on a sales call and got asked how many heat pumps I've installed. They were honest and said <100. The customer balked - that's not a lot at all. (2/many)

100

Shreyas Sudhakar @shreyassudhakar.com · 26/08/2026

We talk a lot about speed and scale when it comes to solar, batteries, and heat pumps. And it's warranted! We need to decarbonize fast, and there's a lot of work to do. There's >1.5 million gas furnaces in the SF Bay Area alone that we need to replace with heat pumps. (1/many) 🧵

120

This is a huge win!! Kudos to everyone that has been pushing this bill forward, it has been a long time in the making

Shreyas Sudhakar @shreyassudhakar.com · 24/08/2026

Ah misread. Your air handler for hvac is going to be pulling much more airflow than a water heater, return ducts are generally at a light negative pressure, I’d wager you’d be better served pulling ambient air for intake from elsewhere

000

Shreyas Sudhakar @shreyassudhakar.com · 24/08/2026

If it’s winter and you’re trying to heat your house, you’re dumping a bit of extra cold air in the intake that now has to be heated more than ambient air

111

That’s one of the reasons we think the group buy mechanism really works for heat pumps! When it’s on your mind, you can get the decision off your mind quickly and make the right choice rather than the desperate one.

020

The shirts turned out great! But we would definitely have been in better shape, paid less, and been way less stressed if we’d planned ahead.

100

Sort of like when your AC dies mid-summer. You'll take the first guy who shows up. No time to be picky.

100

Needed last-minute shirts for our team. Somehow ended up at an arcade in SF that doubles as a screen-printing shop 😅

Shreyas Sudhakar @shreyassudhakar.com · 15/08/2026

You said it better than I could have, Jeff! Thank you!!

We still have a long way to go, but we're making our little dent in getting 6 million heat pumps installed in California, the right way. And having so much fun along the way! (6/6)

152

The stats are pretty brutal. 80% of new HVAC businesses fail in the first year. We made it over the first hurdle! It's been so rewarding to see this blossom from a napkin sketch to where we are today. (5/6)

- Our work has been picked up in so many cool publications: Wired, Canary Media, The Washington Post, The SF Chronicle, Inside Climate News, and many more - Our customers have been our biggest champions and sing our praises to their friends and family. I'm eternally grateful (4/6)

A New Way to Buy and Sell Heat Pumps

Had a great time chatting with ACHRnews about our group buy model! We talked about how we vet our licensed contractor partners, why we focus on ducted replacements, and how planned heat pump upgrades save homeowners money vs. emergency swap-ins. www.achrnews.com/articles/166...

achrnews.com

A new group buying model is helping HVAC contractors generate heat pump leads more efficiently, while offering homeowners lower prices and a simpler buying experience.

153

Then (to my understanding) they pay Costco a referral fee if they get a customer through Costco. And usually that fee gets baked into your price. Often the most expensive (and also often lowest quality) hvac installations are if you get them through Costco, Home Depot, or other big box stores(2/2)

Technically they do, but it’s actually an awful way to get a heat pump right now (unlike everything else at Costco!) They have a partnership with the brand Lennox, where local hvac companies that sell Lennox equipment can market their stuff at Costco. (1/2)

Just California for now! Maybe one day!!
