I’m thrilled to announce @vayu.pro, my new heat pump installation company! 🧵
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).

Getting rid of one-way ACs is a no brainer. Would you buy a car without a reverse gear?
Out: bans on natural gas hookups or appliances
In: bans on central air conditioners that can't do heating
Once again, California is testing it out first.

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!

Every time there is a major earthquake, gas lines erupt in flames. Deeply irresponsible by the city, county, and state to not take this opportunity to remove the risk of gas from neighborhoods.

Utility company Southern California Gas is using ratepayer funds to incentivize Los Angeles wildfire survivors to rebuild their homes with gas appliances. And the California Public Utilities Commissions is letting it happen. insideclimatenews.org/news/0312202... via @hilarybeaumont.bsky.social
LA Wildfire Survivors Want to Rebuild All-Electric, but a Utility Is Using Customer Funds to Incentivize Gas Appliances - Inside Climate News
California’s utility regulator said it would eliminate ratepayer-funded incentives for gas appliances in new construction, but created an exception that allows rebates for them in wildfire rebuilds.
