This is misinformation. I change anc modes using the air pod while connected to my non root android device. The anc works identically when connected to an Apple device

You needed to have configured it on Mac/iOS though.

You've kind of exposed me, I'm not in the US, my question was in the first person but it was more that I'm curious as to the causes of what the commenters report. You may be right about the area just being HCoL, though.
danielsju6 · 2 months ago
Not in a HCoL area, quite the opposite in fact. Rural Maine.

Heat pumps are still a luxury product here that you only see on new homes or well financed gut remodels, which I think is the problem. As market is largely price insensitive individuals here, there’s no downward pressure.

I live in Asia and I'm in charge of air conditioning at my company. A ductless A/c is approximately $1,200 installed. $20k? You should put a split unit in each room. If one breaks, go sleep in the other room. I have 6 of them installed in my apartment.
danielsju6 · 2 months ago
The $20k quote was for two ductless units, with two heads each, which would just cover the bedrooms in my home.

Quite the racket here in the US. They’re still a luxury product.

It's the opposite for me, much bigger ROI on the heatpump than solar. Rural property, 10 years old, ~3,500 sq ft + basement, in Canada where summer can be above 30C (86F) and winter below -30C (-20F). Electricity costs (Canadian) 7.6 ¢/kWh off-peak and 15.8 ¢/kWh on-peak here.

I spent C$40K (about US$30k) on a ground source aka 'geothermal' heat pump to replace furnace powered by propane tank. I kept propane for on-demand hot water and whole house generator. I have no options for utilities other than electricity.

A couple of years later I spent another C$40k for a 20kW rooftop solar system, with net metering and no battery. Net metering was critical for getting any return at all. A battery is next to useless here- I generate almost all of my solar electricity in May-Oct but use the majority of it in Nov-April. Net metering lets me 'store' excess from summer and use it in winter.

Annual costs:

Before:

    C$8,000+ propane (heating + hot water)
    C$2,500 electricity (cooling + misc)
    $10,500 total
With C$40k investment in geothermal heatpump:

    C$4,500 electricity (heating + cooling + misc)
    C$500 propane (hot water)
    C$5,000 total.
With heatpump and then C$40k investment in rooftop solar:

    C$2,000 electricity (heating + cooling + misc)
    C$500 propane (hot water)
    C$2,500 total.
So I'm seeing about C$8k/yr saving for C$80k investment. The heatpump saved me over $5k a year and the solar about $2,500 a year. The heatpump has pretty much paid for itself after 5 years, the solar will take at least 15 years (unless prices go way up) although should eventually see some return 15-20 years out.

In reality it might have cost even more than that to heat with propane. On the propane furnace we barely heated in winter, burned a lot of firewood to make part of the house livable. I'm trying estimate how much it would cost to heat the house to a comfortable 20C (68F) although the thermostat now with the heatpump is set to 22C (72F) in winter so there's an improvement in comfort as well as the ROI.

For me it helped with the ROI because I couldn't go any larger than a 6kw array due to roof shape/exposure. Only roof mounted solar is permitted in my community :/ So a ductless saved us energy in the summer months vs. window units, so I could bank more with net metering when the sun was shining.

This is talking about cold-climate heat pumps. A $200 window AC isn't going to heat your house when it's way below freezing outside.

$20k USD is insane though. I live in Ontario and we paid $12k CAD (pre-government subsidy) for a modern heat pump with a backup high efficiency furnace for when temperatures dip down to -40 or lower.

danielsju6 · 2 months ago
True. We have natural gas and an existing steam radiator setup though, for the two months a year window heat pumps can't keep up. The upfront investment alone would heat my house for 10-20 years.

Honestly, just piling more insulation in the attic and doing an energy audit will probably put the ROI out another 10+ years...

I'm hoping the newer window units that are being rolled out to the NYC market will be good enough to put downward pressure on the outrageous prices in the installation market. Or maybe I'll just dedicate a weekend to DIYing :P

Maybe I have scar tissue from COVID prices but $20k to install a ductless heat pump vs. a $200 to throw a window A/C in or $700 for a portable heat pump. While I get that these heat pumps are better for the environment and much more efficient it's a last mile issue. The installers charge an arm and a leg and I'm not hurting enough to self install. I'm hoping the window heat pumps that just run off mains will be available to more markets soon, I could buy one of those for every room in my house for less than the install on a single mini split.

Where it did make sense was when I was getting solar. It was only a few thousand since I already had the trades out and reducing the load was important for the ROI on the panels.

And what about the 100's of billions in fallout regarding this massive shift in US manufacturing?

Oh no, some billionaires will need smaller yachts.

It does though?, PVC is manufactured using this chemical and rail is an efficient means of transporting it, it is not much deeper than that.
danielsju6 · 3 years ago
From what I heard most countries don’t allow this chemical to be transported, only produced on site with much safer to transport precursors.

That's fairly common, most banks have "overdraft protection" that works exactly how you described.
danielsju6 · 3 years ago
Then they charge $30 to reject the transaction, another $30 when you go "odd and try to swipe again", then extra money because you didn't have the $30 to cover the fee in your account, then recursively until you're $1200 in the hole and they're refusing to cover it.
