💡 Brand context
Haier Smart Home is the largest home appliance manufacturer in the world by volume since 2012, according to Euromonitor. In air conditioning, it has been in Europe since 2001 and acquired GEA (General Electric's air conditioning business) in 2018, which strengthened its technological position. In Spain, the series FLEXIS It is the best-selling in the online channel and among distributors with competitive pricing. Haier operates here directly with national distribution and official technical service, something that not all Chinese manufacturers have consistently established.
Haier in the Spanish market: practical assessment
From our workshop, the impression of the Haier equipment we service in Madrid is this:
The positive: The FLEXIS series offers a real A++ efficiency with a purchase price significantly below the equivalent ranges of Daikin or Mitsubishi. The WiFi and the hOn app (Haier) work properly. The availability of spare parts has improved considerably since 2021; spare parts for current models are accessible within 24‑48 hours.
What you need to know: The documented average lifespan of Haier compressors in European installations is lower than that of premium Japanese brands. In apartments with very intensive use (summer 10+ h/day, winter also active), some technicians prefer to recommend brands with a better long-term track record. For moderate use or a second home, the FLEXIS offers a quality/price ratio that is hard to match.

Frequently Asked Questions about Haier
Para uso moderado‑normal (6‑8 h/día en temporada alta) las referencias son positivas. El compresor rotatif inverter que usa el FLEXIS es el mismo tipo que emplean marcas de mayor precio, y en los primeros 5‑7 años no presenta una tasa de averías apreciablemente superior. Donde se nota la diferencia es en uso muy intensivo (12+h/día todo el año): ahí, la construcción de los modelos premium japoneses aguanta mejor a largo plazo. Para el perfil de uso medio en Madrid (verano fuerte, invierno moderado), el FLEXIS es una opción sólida.
The hOn app (iOS and Android) works correctly for remote control. Integration with Google Home is available on current FLEXIS models and works for on/off and temperature change. Integration with Apple HomeKit is more limited. The historical weak point was 5 GHz connectivity (only 2.4 GHz): if your router only broadcasts at 5 GHz, you need to adjust the configuration.
Internal filters: clean them every 3-4 weeks during active use. Complete annual technical maintenance: cleaning of the evaporator, condenser, drainage pipe, and electrical inspection. Haier recommends annual preventive maintenance to maintain the optional extended warranty.
