We arrive with a complete set of instruments. Manometers for pressures, contact and infrared thermometers, electronic gas leak detector, multimeter, and clamp meter for electrical measurements. We also bring the specific diagnostic application for each brand to read error codes stored on the board. Professional diagnosis when the air is not cooling as before. Gas leaks, compressor, electronics, and sensors. Repair or replacement depending on the case. Locating and repairing leaks, replacing parts, or recharging gas based on diagnosis.

Internal fan blocked by accumulated dirt or worn bearings. When the fan does not rotate at the correct speed, air does not circulate properly over the coil, and the cooling sensation in the room is much lower even if the unit is working. Diagnosis begins with a brief interview with the client about when the problem started, how it manifests, if anything extraordinary happened before (storm, unit moved, impact). It continues with a visual inspection for oil stains indicating leaks, visible mechanical damage, accumulated dirt. Then electrical measurements and refrigeration analysis with manometers. Once the cause is identified, a fixed quote for the repair is provided, compared with the cost of new equipment if the fault is significant. Gas leak at the outdoor unit connection, especially in units over 5 years old. Salt spray and thermal expansion from summer to winter loosen the connections. A small leak gradually reduces the charge, and the unit cools less effectively each season. Repair involves detection with a professional gas detector, replacing the fitting or re-soldering the copper, vacuuming, and a new charge.

For premium units from recognised brands (Mitsubishi, Daikin, LG) aged 10-12 years, repair usually still makes sense because the overall quality justifies extending the lifespan. For basic units aged 7-8 years, replacement is almost always the reasonable decision. Failed electronic board due to overvoltage, humidity, or component aging. This is relatively frequent in areas with thunderstorms, like the interior of Vega Baja in August. Repair may involve replacing the entire board or, if locatable, replacing a specific capacitor or resistor. It depends heavily on the model and parts availability. 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 gas recharging in Provençals del Poblenou typically ranges between €126 and €1602. The final amount depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. Both. We always repair if the repair makes economic sense. If it exceeds 60 percent of the price of new equipment, we will tell you and you decide. As a general rule, if the repair cost exceeds 60 percent of the cost of an equivalent new unit, it is not worth it. This is because repairing an expensive component leaves the rest of the unit at its actual age. Other components will start failing soon. Replacing the compressor of a nine-year-old unit for a significant amount, knowing that the electronics and fans are also aging, is generally a poor investment.
