What is a heat-and-cool air conditioner?
Quick answer: it's a portable unit with a heat pump — the same device that cools can also reverse the cycle and heat the room in winter, plugged into a normal socket.
Is it worth paying more for heating and cooling?
It's worth it if you want a single device all year and don't have efficient heating. If you only need to fight the summer heat, a cooling-only model is cheaper and enough.
Pros
Two uses in one device; fast zoned heating; portable between rooms.
Cons
More expensive; uses a fair amount of power in winter; doesn't replace central heating in a large home.
Best heat-and-cool models
| Model | BTU | Note | Where |

How much does it use in winter?
In heating mode, a portable unit sits around 1000–1500 W. It's handy for heating a room quickly, but for heavy use all winter the costs add up — an inverter heat pump is more efficient.
AC Rental Lisbon's recommendation
For a home in Lisbon, heat-and-cool makes sense mainly in flats without heating. If the goal is only summer, save money and choose cooling-only — or rent one during the heatwave.
