ChillFlex Pro AXP26U338CW

What is good

  • Rated for larger rooms (manufacturer claims up to 40 m2)
  • Premium build and finish options
  • Eco R290 refrigerant

What to watch

  • Single-hose, so the 30-40 m2 claim is optimistic in real heat
  • Up to 64 dB(A) at full speed
  • No Wi-Fi on this variant

Installation & the rules that apply

This is a portable monobloc. The most regulation-light option by far. No F-gas certified installer is needed because you never break into the refrigerant circuit, no planning permission or permit is triggered since nothing is fixed to the building, and a landlord usually cannot refuse it as there are no permanent alterations. The main constraints are the tenancy or building rules on window-kit appearance and noise nuisance to neighbours.
