I agree, in fact a couple things in the pitch don't add up.

> ... where the 80M single family homes in the US replace their furnaces with heat pumps.

Where did they get this statistic? I already have a heat pump and know many that do too. Are we included in this 80M estimate? What about those in the northern half of the US that also need back-up heat for when it is very cold? They aren't going to replace their furnaces with a heat pump. They might add one to their setup but replace, no.

> In addition the process of getting a heat pump is painful, including finding a trustworthy contractor, sorting out financing, and wading through rebates. And finally contractors struggle with installs because of the difficulty of properly sizing the system, and understanding if your duct work is compatible with a heat pump

I don't know the contractors they are talking about, but I literally had to say the words "heat pump" to my local Carrier installer and they did all the rest.

This heat pump is supposed to work to -15F and includes back-up resistive heat. Theoretically it can replace a heater and air conditioner anywhere. I know people north of Chicago that use a similar heat pump and resistive backup system and it's been fine to -30F keeping the house at 69F.

There's definitely a bias against them when natural gas is available. Until probably the past 3-4 years very few HVAC contractors in the midwest were familiar with heat pumps or had bad experiences 5-15 years back and recommended against them as it's "too cold" for them to work here.

My gas-powered water heater failed in my northern US location. I asked a friend who’s a plumbing engineer (!) who said to get a heat pump. I called the HVAC company which had installed the gas water heater and gas furnace some years before and asked for a heat pump water hearer, and they said oh yeah we sell one of those and people love it. I get the feeling that as you say 5-15 years ago it would have been a different story but now it’s routine.
Heat pump water heaters are great, also a much simpler install than an HVAC system.
Resistive heating is very extremely inefficient compared to gas though
Clarification: resistive heating is very near 100% efficient, meaning that all of the energy you pull ends up in the air or water it is meant for. Gas water heating is at the very best ~90-95% efficient (e.g., top-end condensing tankless water heaters), but often as low as 60%: plenty of heat going out the exhaust. You think resistive heating is inefficient because policy has made electricity much more expensive per kwh than gas/oil.
Only 17% of homes have heat pumps at the moment. 80M (though I believe its closer to 88M) homes in the US are single family detached homes.

What region are you in? Local contractor knowledge around heat pumps is quite regional.

Why would 13.6M homes with heat pumps need to replace their heat pump with a heat pump?

What percentage of that 80M single family homes have a climate that can run on heat pumps?
