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.

Haier in the Spanish market: practical assessment
From our workshop, the impression of the Haier equipment we service in Madrid is this:
Availability and lead time are confirmed for the specific reference and destination before accepting the order. Not all parts are in stock or have the same supply time.
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
For moderate-normal use (6-8 hours/day during peak season), the references are positive. The inverter rotary compressor used in the FLEXIS is the same type employed by higher-priced brands, and in the first 5-7 years, it does not show a significantly higher fault rate. The difference is noticeable in very intensive use (12+ hours/day all year round): there, the construction of premium Japanese models holds up better in the long term. For the average usage profile in Madrid (strong summer, moderate winter), the FLEXIS is a solid option.
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.
