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.
Because it costs about $5 more to put in a valve which lets them work both ways, and people don’t really know that this is a possibility, so they don’t ask for it.
Most modern ones are. But the old models don’t have a reverse cycle built into them. Also, for efficient heating in low temperatures you might want a different gas. Maybe not as relevant in California, but normally you wouldn’t be able to use your AC as a heat pump in below 0 celcius.
Wait arent air conditioners heat pumps???
