A call to replace air conditioners with heat pumps in California
A call to replace air conditioners with heat pumps in California
Advocates want new building codes to include a heat-pump provision that could benefit consumers and the climate. But regulators have cooled on the proposal.
You're viewing a single thread.
What are the environmental impacts of manufacturing of replacement heat pump units to replace functioning A/C units vs keeping them?
This is about a regulation for new construction, so it's kind of a moot point.
The key question is going to be whether refrigerant in the old unit is properly disposed of. Likely a net benefit so long as it is.
If the existing A/C don't support heating, then presumably heat pumps are displacing far inferior gas or resistive electric units (or even wood burning heaters). Heat pumps absolutely destroy them in terms of efficiency, and it's hard to believe the embodied emissions plus ongoing emissions would be worse with a heat pump. And just as importantly, the fossil fuel industry needs to be made unprofitable as soon as possible, and anything that gets people off gas is therefore a good thing.
we need to mandate that any AC unit also be a heat pump to sell it here, it's like one valve difference just mandate it 5 years out. also ban gas lines to new buildings
Water heaters can work via the refrigeration cycle as well.
