A short, single-speaker YouTube video (shorts) explains that a refrigerator functions as a heat pump—removing heat from its interior and releasing it outside (or into the room)—and uses that analogy to say many home HVAC units are heat pumps that move heat out of the home. The tone is conversational and aimed at homeowners.
I've actually gotten this question a few times, and everyone has a heat pump in their house. It's called a refrigerator. When you put stuff in the fridge, it takes the heat out and puts it in the home. Well, your unit works the same way for a heat pump. It takes the heat out of the home and puts that outside where no one cares about it. So if you have H VAC system in your home, it's a good chance you have a heat pump.
