Repair Air Conditioners HAIER – Valais

2. Diagnosis Our technician carries out a thorough on-site assessment of your Haier system, inspecting critical components including the rotary inverter compressor, the internal condensate pump, the heat exchanger, and the inverter control board — a component particularly vulnerable to voltage surges during Swiss electrical storms. We use professional diagnostic tools to read error codes, measure refrigerant pressure (checking for R32 or R410A leaks that commonly cause insufficient heating or cooling), and evaluate airflow through the evaporator and axial fan on the outdoor unit.

3. Repair Once the fault is confirmed and you've approved the transparent, no-obligation quote, our technician proceeds with the repair using original or certified-compatible Haier spare parts. Whether it's recharging refrigerant to factory specifications, replacing a damaged inverter board, clearing a blocked condensate drain that is causing water ingress, or de-icing and freeing a seized outdoor fan, every intervention follows Haier's technical standards.

4. Guarantee All repairs carried out by Swissrepair come with a written warranty on both parts and labour. You receive a clear repair certificate documenting exactly what was done — full transparency in the Swiss tradition. Should the same fault recur within the warranty period, we return and resolve it at no additional cost.
