We arrive with a full set of instruments. Gauges for pressures, contact and infrared thermometers, electronic gas leak detector, multimeter and clamp meter for electrical measurements. We also bring the specific diagnostic app for each brand to read error codes stored in the control board. Call us, message us on WhatsApp, or request your quote online – we'll reply in under 10 minutes during business hours. A complete aerothermal installation is a serious project. It starts with calculating the thermal loads of the home, sizing the unit according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the domestic hot water tank and the outdoor unit, and a fixed quote.

Control board failure due to power surge, moisture, or component aging. It's relatively common in areas with electrical storms like the interior of Vega Baja in August. The repair might involve replacing the entire board or, if identifiable, replacing a specific capacitor or resistor. It depends heavily on the model and parts availability. Indoor fan blocked by accumulated dirt or worn bearings. When the fan doesn't spin at the correct speed, air doesn't circulate properly over the coil, and the cooling sensation in the room is significantly reduced even if the unit is running. Refrigerant leak at the outdoor unit connection, especially in units over 5 years old. Salt spray and thermal expansion/contraction from summer/winter can loosen the fittings. A small leak gradually reduces the charge, and the unit cools less effectively each season. The repair involves detection with a professional gas detector, replacing the fitting or brazing the copper, vacuuming, and recharging.

For premium units from recognised brands (Mitsubishi, Daikin, LG) aged 10-12 years, repair is usually still worthwhile because the overall quality justifies extending its lifespan. For basic units aged 7-8 years, replacement is almost always the sensible decision. Standard components (remotes, capacitors, sensors) yes. Control boards and compressors are ordered and arrive in 2-7 days depending on the brand and model. Mitsubishi, Daikin, LG, Toshiba, Samsung, Panasonic, Fujitsu, Hitachi, Hisense, and others. For official warranty service, we direct you to the brand's authorised service centre.

The cost of split installation in Sant Just Desvern typically ranges from €148 to €1224. The final figure depends on the condition of the property, materials, and labour time. We always provide a fixed quote before starting. As a general rule, if the repair exceeds 60 percent of the cost of an equivalent new unit, it's not cost-effective. This is because repairing an expensive component leaves the rest of the unit at its current age. Other components will likely start failing soon. Replacing the compressor of a nine-year-old unit for a significant amount, knowing that the electronics and fans are also ageing, is generally a bad investment. Seized compressor in economy-range units with 6-9 years of intensive use. This is the most expensive breakdown. Replacing the compressor costs a considerable portion of a new unit's price and is only worthwhile for premium units with a reasonable remaining lifespan. For basic units, we generally recommend replacement.
