| in the south, a lot of people opt for split Airconditioning instead of heatpumps. Cheaper and much easier to install/maintain |

| Do the places you are referring to not require heat? If so I don't see why having a separate heating and cooling system would be cheaper to maintain than a single system. Come to think of it I don't see why a heatpump would be more expensive to maintain than split AC. I guess there is some extra circuitry to make sure it doesn't ice up in the winter and maybe backup resistance heating builtin. |

| That's the same thing, no? |

| ▲ | gosub100 4 hours ago | parent | prev [-] | | I think they mean "air exchange" (split AC) vs "heat pump" (dig into the earth to draw/eliminate heat). Not saying that's the right definition though. I am guessing at an auto-correction of what they meant. | | |
| ▲ | ericd 3 hours ago | parent | next [-] | | Dug into the ground, we usually call a "ground source heat pump", or less accurately, "geothermal". The normal split systems are "air source heat pumps". AC is a heat pump without a reversing valve. | |
| ▲ | ane 3 hours ago | parent | prev [-] | | A heat pump is not necessarily dug into the earth. Rather, the flow of the heat pump is moving heat (thermal energy) from outdoors to indoors or the other way around in an air conditioner. Depending on the direction of the coolant flow, you get either a indoor heating or cooling unit. This is best demonstrated by going in front of the outdoor unit of a heat pump, when they are cooling, the outdoor unit generates heat because it's compressing gas, which then is then expanded when it reaches the indoor unit, generating cold. Exactly like a refridgerator. |

| Why would it be easier to install/maintain? It's basically the same machine. |

| Split units are heat pumps right? They heat and cool. What’s the catch? They don’t have a very high range of operation? |
