Yes, it’s a similar situation in the US! Many folks (especially on the west coast, where summers have historically been mild) don’t have an AC, so big motivation to install a heat pump is to add AC! Unfortunately, plenty of one-way ACs are still being installed; each of those is a missed opportunity where a heat pump could have been put in and decarbonized heating at the same time
I'm in Texas, and my HVAC guys all switched to heat pumps on their own houses a few years ago. The main problem is that most of are on electric AC and gas/propane heat; so, the switch to heat pump usually means throwing out either a perfectly good AC or a perfectly good heater, and installing a heat pump which is, generally about 50% more expensive than either: it's just a lot for a homeowner to swallow. For new builds, the entrenched builders have backlogs of old equipment that they don't want to lose capital on. It's a tough cycle to break.
A shame, really, because they're so nice. And in the US you can even DIY the install! (It cost twice as much to get one in Ireland because I needed an F Gas certified tech).
Is aircon rare on the west coast? I recall basically everywhere having it when I grew up in Sacramento. But I do remember it being less common in San Diego...
Sacramento is not “on the coast”, more of Central Valley, so it does get hot.
Where I live in the “Peninsula” part of Bay Area, we may “want” rather than need A/C maybe 1 week a year. My heating is provided by a 15 year old forced air gas furnace, but I’m in no hurry to install a heatpump because of our ridiculous electrical costs - thanks PG&E.
Our current rates seem to already average at $.5/kwh, probably 5 times more than the rest of the country.
I would wager that adoption of heatpumps is related to cost of electricity vs gas
Nomenclature but I generally think of the west coast on the national scale, but you're correct. I mean, downtown LA is definitely the west coast but it can be much much hotter than Santa Monica, 15 miles away.
But you're right that expensive electricity kills the value proposition.
Is the problem up-front cost on the heat pump (vs pure AC)?
I have a friend remodeling a home in Seattle right now and they’re installing a heat pump in the extension/basement. Seems like a no-brainer given the relatively mild highs and lows. The original house had no AC and radiators of some sort (1920s build, maybe).
Seattle is a great place for a heat pump. Depending on where you are, and your tree cover, most summer days are fine with windows open, but heat waves are icky. Otoh, below freezing is pretty rare, so most of the time, you'll be in the efficiency zone; on the big snow days, it's useful to move snow away from your outside unit to keep it working as well as it can in those conditions. Wall mounted units, common with mini-splits, probably don't have to worry about that.
Utility natural gas is available in some places in the region, but not everywhere... Heating with propane would be pretty expensive, IMHO.
Yeah, they were fine without AC for years. But, with a kid on the way, they wanted more space, and liked their neighborhood enough to remodel vs move. Outside of the remodel, probably wouldn’t make sene to install AC/heat-pump, but once you’re spending hundreds of thousands, it’s a drop in the bucket and making a heatpump made sense.
I'd love AC, but I'd only need it for a couple weeks a year in the bay area.
And I have PG&E so the economics of a heat pump don't pencil out. Gas heating is still cheaper than a heat pump because electricity rates are out of control. (Gas isn't cheap either but still cheaper)
California is doing everything it can to eliminate natural gas heating except for make the alternatives more affordable. PG&E and Socal Edison are basically given a bank check to keep raising rates by the oversight board. (Doesn't help that they are also burning down cities)
