The heat pump water heater price difference was outrageous!
$4600 is high for the midwest, but I can see it. $7000 is highway robbery. And I seldom give contractors a hard time for pricing.
That's what having fear priced in looks like, or not wanting the job.
Most of California can basically swap a furnace for a heat pump, although the experience with single stage equipment may be mediocre (loud and lots of blowing air.)
Cold climates need to swap very carefully or experiences will suck, which will act like an anchor on demand.
I haven't been able to find the article again, but ~60% of US home natural gas use is in 8 cold climate states (CA and TX are another 20%, heavy on water heat usage.)
Cold climates MUST be solved for, and they are a b*tch on both contractor and homeowner fronts.
I was off a bit, 60% in the top 11 states, excluding CA and TX 48%.
Note use per capita for CA and TX about half the others.

This is part of integrated project design - have a plan so you can hold everyone accountable. A duct design is not totally sacred, there will be challenges in the real world not reflected here, but it helps guide the project and deliver better results.
This isn't needed on every job, but it should always be available if needed.
@RDCFineHomes@MontePaulsen@briansiana@UCSUSA Good question. Pragmatists and conservatives. This is adapted from Geoffrey Moore's "Crossing the Chasm". Everyone should read that book.
They require a "complete product" that is demonstrably better than current options. It needs to be easy to procure and readily available.
That's remarkable. It truly replaced an ICE vehicle.
@RDCFineHomes@MontePaulsen@briansiana@UCSUSA@EfficiencyLast For houses a broad solution is needed that can apply to most homes and require little to no thought from the owner. That's why we use high end communicating equipment. It looks like a furnace and the thermostat is familiar. It does the thinking for people.
I hope this finds you well in the current craziness.
You all have advanced HVAC systems that can help at least somewhat to reduce the risk of COVID19 (and sickness in general) as most of us are spending more time in our homes than usual.

I did a bunch of research and 3 things are clear:
1. Humidity - Maintain relative humidity between 30-50%. This keeps small droplets in our breath from shrinking to be super small where they are difficult to filter, and those levels also seem to inactivate viruses.

Want a universal path to solving for climate change?
Stop talking climate and start talking pollution. Pollution is a clear and present danger, we know how to solve it, and we get a fast feedback loop because it's easy to measure. The solutions are almost identical.
My buddy Doug Hunt of Palmers Heating and Cooling posted this. Let's just say he wouldn't agree politically with most in CA.
But there's common ground on pollution.
Conservation is inherently conservative. Teddy Roosevelt started the national parks, Nixon started the EPA.
Oh, and Reagan sold electrification in the 50s. I have one of the pictured medallions.
@lenox_matt It sure gets us into a lot of arguments though!
We need more Teslas - companies that make a new tech accessible to the masses.
Fingers crossed we're about to pull that off for residential HVAC. What's your focus?
@lenox_matt One last concept to wrap it up. There's a sweet spot where additional money spent or work done doesn't deliver substantially better results.
That's the Sweet Spot. It's what we try to figure out for every client and every home.
@lenox_matt We've consistently found that when it comes to solving persistent comfort, health, or moisture problems in a home, half measures lead to quarter results at best.
You have to hit a problem hard, but not spend so much money that it's a poor use of resources. Tough balance.
