Hisense Group It is one of the largest electronics groups in China, based in Qingdao. In Spain, it has been selling televisions since 2012 and has progressively expanded its range of air conditioning products. Although the initial perception was that of a low-cost brand, the models from the ExpertPlus and Expert ranges starting in 2020 have significantly improved in efficiency and reliability, and their A++ rating is genuine (verified by European certification bodies). Hisense has been the official sponsor of the FIFA World Cup since 2018, reflecting its current positioning as an emerging global brand.
Hisense in 2025: practical evaluation from the workshop
The perception of Hisense among installers in Madrid has changed in the last 4-5 years. The equipment we see in the workshop from the 2018-2020 generation had more variability in quality: PCBs that were somewhat more fragile in humid conditions, terminal connectors prone to oxidation. The models from the 2021 generation onwards (ExpertPlus, Expert PRO) have significantly improved in component durability, and the availability of official spare parts has improved with the opening of the logistics warehouse in Spain.
In summary: Hisense from the current generation is a good option for a tight budget, although it still doesn't match the average longevity of Japanese brands under intensive use. For rental apartments, students, or second homes, its price/efficiency ratio is very competitive.

Frequently Asked Questions about Hisense in Madrid
The most basic APC models do not have integrated WiFi or a PCB connector for an external module. The latest generation APC models (from 2022) do include the WiFi module from the factory. Check the exact model: if "WiFi" or "WF" appears in the model name on the box or sticker, it has it integrated. If not, it is not compatible with an added module.
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.
Internal filters: clean every 2-4 weeks during intensive use. Complete technical maintenance annually: cleaning of evaporator and condenser, drainage inspection, and electrical check. With regular maintenance, the lifespan is significantly extended and faults caused by accumulated dirt (the most common cause in mid-priced equipment) are avoided.
