I’m thrilled to announce @vayu.pro, my new heat pump installation company! 🧵
Incredible stuff, thanks to the leadership of @scottwiener.bsky.social, @buildingdecarb.org, @spur-urbanist.bsky.social, and so many others pushing this important legislation forward! Under the radar, "unsexy" policies like this meaningfully make electrification and heat pump adoption more possible
Cheers to the passage of CA #SB222 (now moves to the Assembly). The #HeatPumpAccessAct enables faster, easier, more affordable heat pump installations. Clean energy is cheap, resilient energy. Heat pumps are the future, 3-5x more efficient than natural gas or oil systems. bit.ly/4qNArSG

You hate to see it.
If you recently installed a furnace + 1-Way AC instead of a heat pump, why did you do it?

Ok, so there's a cool easter egg on our new heat pump group buy website.
It has something to do with this guy.

Benchmark futures ⬇️ 10% on Monday after ⬆️ 30% last week. There were real reasons for prices to be moving... but the sheer size of the swings reflected the clout of speculative traders

If your only criteria when evaluating HVAC bids is cost, you might be setting yourself up for a world of hurt down the line.

Getting a heat pump can be scary!
It's a big part of why we've built with a digital-first sales process. For most customers, we're able to accurately price projects without ever stepping foot in their house.
One less excuse to take a sick day home from work...

Most small HVAC business owners aren't laughing their way to the bank.
It takes a lot to run a business like this - tools, equipment, salaries, insurance policies. All of that adds up.
If you get sticker shock when you get a heat pump quote, many times it's simply the cost of doing business

I love when we get 5 star reviews on Google.
But sometimes a handwritten note from a @vayu.pro customer is even more rewarding!

Being small is an unfair advantage.
Every single call, text and email at @vayu.pro goes straight to my cell phone.
No call centers, no answering service.
In a world where most HVAC contractors never return your calls, it's a huge win.
(PS: Yes, I know, I'll charge my phone!)

I had to double take when I spotted this plaque:
“Medallion Home — Live Better Electrically.”
Turns out it was part of a major national campaign in the 1950s and early 60s to promote all-electric homes.

Electrifying doesn't have to be hard.
That's my dinner last night, being cooked on an induction wok sitting on top of my gas range.
Just 50 bucks from Costco!
And zero CO, CH4, NO2, N2O or CH2O (yes - your gas stove dumps all of those things into the air you breathe).

Out: bans on natural gas hookups or appliances
In: bans on central air conditioners that can't do heating

Energy efficiency and demand flexibility can avoid costly power grid buildout, but utilities rarely invest in them because utities profit by putting steel in the ground. This is a main barrier to lowering your power bills. Utility regulators have had decades to fix this but few have done anything.

CHANGE YOUR HVAC FILTERS, FOLKS!
I had a customer give me a call that their heat pump wasn't heating as well as it used to. We scrambled the team to get a technician out there to inspect the system.
When I called back to confirm the visit, everything was already fixed. It was just a dirty filter!
