Gymax

The only air conditioner in this family that also heats

Gymax appears in one family here: portable air conditioners.

What we found writing the review

4-in-1, uniquely in this family. Cool, heat, dehumidify and fan, across a 16–32 °C range — no other portable AC we reviewed publishes a heating mode.

The largest and heaviest unit compared. 16,000 BTU, up to 45 m² coverage, and 34 kg — more than double the capacity and roughly 50% heavier than the entry-priced units in this family.

Confirmed on one market only. At the time of checking, a live New-condition offer existed on Amazon.de alone, of six marketplaces checked — verify current availability before planning a purchase around it.
