Third-party reviews

Based on ratings from across the web.
Reviews last updated: August 2026 · How we calculate this

What we like about Suntec 17353 Coolfixx 3.5

  • Powerful 12,000 BTU cooling capacity suitable for medium to large rooms up to 60 m²
  • Versatile 4-in-1 functionality that cools, heats, dehumidifies, and ventilates
  • Convenient smart ecosystem integration with Wi-Fi control via a smartphone app and a remote control
  • Eco-friendly operation utilizing sustainable R290 refrigerant
  • Solid build quality and good overall value for the price ratio

What we don't like about Suntec 17353 Coolfixx 3.5

  • High operational noise levels reaching up to 65 dB, which users report can disrupt sleep or watching television
  • Noticeably louder operation specifically when using the heating function
  • Bulky and heavy footprint weighing approximately 32 kg, making it hard to move between floors
  • Mixed user feedback regarding long-term durability and the product's lifespan
  • Requires proper management of the heavy exhaust hose and window sealing kit to remain efficient

Verdict

The Suntec 17353 Coolfixx 3.5 Eco R290 is a versatile 4-in-1 portable air conditioner designed for rooms up to 60 m² (130 m³), featuring an energy efficiency class A rating, a robust cooling capacity of 12,000 BTU/h (1,540W power consumption), a heating output of 9,500 BTU/h, a dehumidification rate of 1.1 liters per hour, and 3 ventilation settings driving up to 400 m³/h of air circulation. Key performance pros include its eco-friendly R290 refrigerant, a precise manual temperature range of 16–31 °C, full smart integration via the Suntec Wellness app alongside a standard remote control, and a functional 1–24 hour timer combined with a darkened sleep mode. However, notable drawbacks include its substantial weight of 32 kg, a relatively high full-load operating noise level of up to 65 dB, and the mandatory requirement of routing a bulky exhaust hose to an external window for proper cooling functionality.
