We arrive with a complete set of instruments. Manometers for pressure, contact and infrared thermometers, electronic gas leak detectors, multimeters, and clamp meters for electrical measurements. We also carry brand-specific diagnostic software to read error codes stored in the control board. Professional diagnosis when your air conditioning isn't cooling like before. Gas leaks, compressor issues, electronics, and sensors. Repair or replacement as appropriate. Locating and repairing leaks, replacing parts, or refilling gas based on the diagnosis.

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 analysis with manometers. Once the cause is identified, we provide a fixed quote for the repair, compared against the cost of a new unit if the fault is major. Between 30 minutes and 2 hours depending on complexity. A simple fault is identified quickly. Small leaks or electronic problems may take longer. Fault localisation using certified instruments before proposing a repair.

For premium units from recognised brands (Mitsubishi, Daikin, LG) that are 10-12 years old, repair is often still worthwhile because the overall quality justifies extending the unit's lifespan. For basic units that are 7-8 years old, replacement is almost always the more sensible decision. Failed electronic boards due to power surges, humidity, or component aging. This is relatively common in areas with thunderstorms, like the interior of Vega Baja in August. Repair may involve replacing the entire board or, if identifiable, 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 centre.

The cost of a gas refill in Santa Coloma de Gramenet typically ranges between €126 and €1602. The final amount depends on the condition of the unit, materials, and labour time. We always provide a fixed quote before starting. As a general rule, if the repair cost exceeds 60 percent of the price of an equivalent new unit, it is not cost-effective. The reason is that repairing an expensive component leaves the rest of the unit with its actual age. Other components will likely start failing soon. Replacing the compressor of a nine-year-old unit for a significant sum, knowing that the electronics and fans are also aging, is generally a poor investment. Both. We always repair if the repair makes economic sense. If it exceeds 60 percent of the price of a new unit, we will inform you and you can decide.
