A heat pump isn't more efficient than an air conditioner at cooling, because they're the same thing except a heat pump has a reversing valve.
For heating, running your air condition with a reversing valve so it cools outside and heats inside is often more efficient than a furnace, so that is nice... But irrelevant if we're talking about it being too hot.
- tharkun__ 2y agoAnd how does any of this apply to my comment? I said nothing about any of that. I was commenting on the use of the word "air conditioning" for heating. Which is technically true but not used in that way by like literally anybody. In any regular use of the word AC it implies cooling. Again, to be clear, yes the phrase is usable both ways. No regular person will use it that way. Get used to it instead of making technically correct points that don't help anyone.
