What we like about KESSER Split 12000 BTU

  • Excellent cooling speed, managing to cool spaces like an 18-square-meter bedroom in about 20 minutes
  • High value for money with great energy efficiency ratings (A++ for cooling and A+ or A++ for heating)
  • Convenient smart control options via Wi-Fi and a smartphone app from anywhere
  • Comprehensive complete kit packaging that includes standard mounting materials and copper pipes
  • Quiet indoor operation, specifically praised when utilizing the dedicated silent sleep mode
  • Versatile year-round performance offering reliable cooling, efficient heating, and integrated dehumidification

What we don't like about KESSER Split 12000 BTU

  • Initial installation can be complex for inexperienced users, often making professional setup advisable
  • The outdoor unit operation can be noticeably louder or have slightly jerkier start-and-stop transitions compared to premium brands
  • Potential risk of individual Wi-Fi, Bluetooth, or technical module defects over extended long-term use
  • Conflicting or inconsistent manufacturer specifications regarding the exact energy efficiency (SCOP) values

Verdict

The KESSER Split 12000 BTU (3,400 Watts) air conditioner features an energy-efficient DC Full-Inverter compressor pre-charged with eco-friendly R32 refrigerant, delivering a strong airflow of 550 m³/h with an A++ cooling and A+ heating efficiency rating. This versatile system includes integrated WiFi/App functionality, an illuminated LCD remote control, a 24-hour timer, and a protective Golden-Fin anti-bacterial coating on both the indoor and outdoor units to prevent residue build-up. Main advantages include its quick-connect installation technology, ultra-quiet operation at low decibels, and multi-functional capability as an air cooler, heater, and dehumidifier. However, potential drawbacks include strict EU regulations requiring documented professional certification prior to purchase, and users may occasionally experience brief operational delays or the necessity of installing a dedicated electrical line to prevent blown fuses during high load spikes.
