Leak detection and repair, parts replacement, or gas recharge based on diagnosis. We arrive with a full set of instruments. Gauges for pressure, contact and infrared thermometers, electronic gas leak detector, multimeter, and clamp meter for electrical measurements. We also bring brand-specific diagnostic tools to read error codes stored in the control board.

Professional diagnosis when your air conditioning isn't cooling as well as it used to. Gas leaks, compressor issues, electronics, and sensors. Repair or replacement as needed. Fault location with certified instruments before proposing repairs. When an air conditioning unit stops cooling effectively, there can be several causes that look similar at first glance. The difference lies in the speed and nature of the failure. If the unit has gradually lost efficiency over months, it's most likely a slow gas leak that has reduced the available refrigerant to the point of poor performance. If it was cooling normally and suddenly stopped providing cold air overnight, it's usually a major leak, compressor failure, or a problem with the electronic control board. If it starts but stops after a few minutes with an error message on the remote, it could be the thermostat, a temperature sensor, or a communication issue between units.

Failed electronic control boards due to power surges, humidity, or component aging. This is relatively common in areas with electrical storms, like the interior of Vega Baja in August. Repairs may involve replacing the entire board or, if identifiable, replacing a specific capacitor or resistor. It largely depends on the model and parts availability. For premium units from well-known brands (Mitsubishi, Daikin, LG) that are 10-12 years old, repairs are often still worthwhile as their overall quality justifies extending their useful life. For basic models 7-8 years old, replacement is almost always the reasonable decision. Mitsubishi, Daikin, LG, Toshiba, Samsung, Panasonic, Fujitsu, Hitachi, Hisense, and others. For official warranty service, we refer you to the brand's authorised service centre.

The cost for cleaning and maintenance in Sant Oleguer typically ranges from €130 to €1296. The final price depends on the property's condition, materials used, and working time. We always provide a fixed quote before starting. Older models without inverter technology start and stop abruptly at full power, putting more stress on the compressor. Modern inverter models modulate smoothly and last longer. Their electronics are more sensitive, and from the seventh or eighth year onwards, board failures requiring module replacement begin to appear. The decision between repairing it or replacing the unit depends on the cost of the part versus the price of a new equivalent unit. Burned-out compressors in economy-range units with 6-9 years of intensive use. This is the most expensive failure. Replacing the compressor costs a significant portion of a new unit's price and is only economically viable for premium units with a reasonable remaining lifespan. For basic units, we usually recommend replacement.
