Leak detection and repair, parts replacement, or gas refill based on diagnosis. Diagnosis begins with a brief interview with the client about when the problem started, how it manifests, and if anything unusual happened before (storm, equipment relocation, impact). It continues with a visual inspection for oil stains indicating leaks, visible mechanical damage, or accumulated dirt. Then, electrical measurements and refrigeration analysis with pressure gauges are performed. Once the cause is identified, a fixed quote for the repair is provided, compared with the cost of new equipment if the fault is major. We arrive with a complete set of instruments. Pressure gauges, contact and infrared thermometers, electronic gas leak detector, multimeter, and clamp meter for electrical measurements. We also bring brand-specific diagnostic software to read error codes stored on the board.

Professional diagnosis when the air conditioner isn't cooling properly. Gas leaks, compressor, electronics, and sensors. Repair or replacement as appropriate. Fault localisation using certified instruments before proposing a repair. Exhausted compressor in economic range equipment 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 equipment with a reasonable remaining lifespan. For basic equipment, we usually recommend replacement.

Failed electronic board due to overvoltage, humidity, or component aging. This is relatively common in areas with thunderstorms, like the interior of Vega Baja in August. The repair may involve replacing the entire board or, if identifiable, replacing specific capacitors or resistors. It depends heavily on the model and parts availability. For premium equipment from recognised brands (Mitsubishi, Daikin, LG) aged 10-12 years, repair is still usually worthwhile because the overall quality justifies extending the unit's lifespan. For basic equipment aged 7-8 years, replacement is almost always the sensible decision. Common components (remotes, capacitors, sensors) yes. Electronic boards and compressors are ordered and arrive in 2-7 days depending on brand and model.

The price for a gas refill in Parets del Vallès typically ranges between €126 and €1602. The final figure 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 maximum power, which puts 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 begin to appear, requiring the entire module to be replaced. The difference between repairing it or changing the unit depends on the cost of the part versus the price of an equivalent new unit. As a general rule, if the repair exceeds 60 percent of the cost of an equivalent new unit, it's not worth it. The reason is that repairing an expensive component leaves the rest of the unit at its actual age. Other components will start to fail soon. Replacing the compressor of a nine-year-old unit for a considerable amount, knowing that the electronics and fans are also ageing, is generally a poor investment.
