Leak detection and repair, parts replacement, or gas recharge based on diagnosis. We arrive with a complete set of instruments. Gauges for pressure, contact and infrared thermometers, electronic gas leak detector, multimeter, and clamp meter for electrical measurements. We also carry brand-specific diagnostic software to read error codes stored on the board. Diagnosis begins with a brief interview with the client about when the problem started, how it manifests, and if anything unusual happened beforehand (storm, unit moved, impact). This is followed by a visual inspection for oil stains indicating leaks, visible mechanical damage, or accumulated dirt. Then, electrical measurements and refrigerant system analysis with gauges. Once the cause is identified, we provide a fixed quote for the repair, comparing it with the cost of a new unit if the fault is significant.

Professional diagnosis when your air conditioning doesn't cool like before. Gas leaks, compressor, electronics, and sensor issues. Repair or replacement as appropriate. When an air conditioner stops cooling as it should, there can be several causes that look similar at first glance. The difference lies in the speed and manner 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 amount in the system to the point of malfunction. If the unit was cooling normally and suddenly stopped providing cold air overnight, it's usually a major leak, compressor failure, or an electronic board issue. If it starts but stops after a few minutes with an error message on the remote, it could be the thermostat, temperature sensor, or a communication problem between units. Gas leak at the outdoor unit connection, especially in units over 5 years old. Salt air and seasonal temperature changes can loosen connections. A small leak progressively reduces the charge, causing the unit to cool poorly each season. Repair involves detection with a professional gas detector, replacing the connection or soldering the copper, vacuuming, and recharging.

Failed electronic boards due to power surges, moisture, or component aging. This is relatively common in areas prone to electrical storms, like inland Vega Baja in August. Repair can involve replacing the entire board or, if identifiable, replacing the specific capacitor or resistor. Much depends on the model and parts availability. For premium units from recognised brands (Mitsubishi, Daikin, LG) that are 10-12 years old, repair usually 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. Mitsubishi, Daikin, LG, Toshiba, Samsung, Panasonic, Fujitsu, Hitachi, Hisense, and others. For official warranty, we refer you to the brand's authorised service.

The price for a gas recharge in Vallcarca i els Penitents typically ranges from €126 to €160. The final amount depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. Older models without inverter technology start and stop abruptly at full power, which puts more strain 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 start to appear, requiring the entire module to be replaced. The difference between repairing it or replacing the unit depends on the cost of the part versus the price of a comparable new unit. Burned-out compressor in economy range units with 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 worthwhile for premium units with a reasonable residual lifespan. For basic units, we usually recommend replacement.
