We arrive with a full set of instruments. Gauges for pressure readings, contact and infrared thermometers, an electronic refrigerant leak detector, a multimeter, and a clamp meter for electrical measurements. We also use brand-specific diagnostic software to read error codes stored in the unit's main board. Leak detection and repair, part replacement, or refrigerant recharge based on the diagnosis. Professional diagnosis when your air conditioning isn't cooling as it should. We identify refrigerant leaks, compressor issues, electronic faults, and sensor problems. We then repair or replace parts as necessary.

The indoor fan is 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 room feels much less cool even if the unit is running. Failed electronic control board due to power surges, moisture, or component aging. This is relatively common in areas with electrical storms like the Vega Baja interior in August. Repair might involve replacing the entire board or, if a specific component is identifiable, replacing a particular capacitor or resistor. This depends heavily on the model and parts availability. An overworked compressor in basic models after 6-9 years of intensive use. This is the most expensive fault. Replacing the compressor costs a significant portion of a new unit's price and is only worth it for premium units with a reasonable residual lifespan. For basic units, we usually recommend replacement.

Common components (remote controls, capacitors, sensors) are usually stocked. Electronic boards and compressors are ordered and typically arrive within 2-7 days depending on the brand and model. We service Mitsubishi, Daikin, LG, Toshiba, Samsung, Panasonic, Fujitsu, Hitachi, Hisense, and others. For official warranty services, we direct customers to the brand's authorised service centre. For premium units from recognised brands (Mitsubishi, Daikin, LG) that are 10-12 years old, repair often still makes sense because their overall quality justifies extending their lifespan. For basic units that are 7-8 years old, replacement is almost always the more sensible decision.

The price for a refrigerant gas top-up in Sant Vicenç de Montalt generally ranges between €126 and €1602 as an indicative reference. The final amount depends on the property's condition, materials used, and the time required. We always confirm the price after reviewing photos or —if you prefer— after an on-site inspection, with no obligation. As a general rule, if the repair cost exceeds 60 percent of the price of an equivalent new unit, it's not cost-effective. This is because repairing an expensive component doesn't rejuvenate the rest of the unit, which remains at its actual age. Other components may fail soon after. Replacing a compressor on a nine-year-old unit for a significant sum, knowing that the electronics and fans are also aging, is generally a poor investment. Older models without inverter technology start and stop abruptly at full power, putting more strain on the compressor. Modern inverter models modulate power smoothly and last longer. Their electronics are more sensitive, and starting from the seventh or eighth year, board failures requiring replacement of the entire module can occur. The decision between repairing it or replacing the unit depends on the cost of the replacement part versus the price of a comparable new unit.
