We arrive with a complete set of instruments. Manometers for pressure, 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. Leak detection and repair, parts replacement, or gas refilling based on diagnosis. Professional diagnosis when the air is not cooling as it used to. Gas leaks, compressor, electronics, and sensors. Repair or replacement as appropriate.

The diagnosis begins with a brief interview with the client about when the problem started, how it manifests, if anything unusual happened before (storm, moving the unit, impact). It continues with a visual inspection looking for oil stains that indicate leaks, visible mechanical damage, or accumulated dirt. Then, electrical measurements and refrigerant analysis with manometers. Once the cause is identified, a fixed repair quote is provided, compared against the cost of new equipment if the fault is major. Indoor fan blocked by accumulated dirt or worn bearings. When the fan doesn't spin at the correct speed, air doesn't circulate properly over the coil, and the cooling sensation in the room is much weaker even if the unit is running. Burned-out compressor in budget-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 only makes sense for premium equipment with a reasonable remaining lifespan. For basic units, we usually recommend replacement.

For premium units from recognised brands (Mitsubishi, Daikin, LG) that are 10-12 years old, repair often still makes sense because the overall quality justifies extending their lifespan. For basic units 7-8 years old, replacement is almost always the reasonable decision. Failed electronic board due to power surges, humidity, or component aging. It's relatively common in areas with electrical storms like inland Vega Baja in August. The repair might involve replacing the entire board or, if the specific component can be identified, replacing the faulty capacitor or resistor. It highly depends on the model and parts availability. Common components (remotes, capacitors, sensors) yes. Electronic boards and compressors are ordered and arrive in 2-7 days depending on the brand and model.

The price for gas refilling in Sant Boi de Llobregat typically ranges between €126 and €1602. The final amount depends on the property's condition, materials used, and labour time. We always provide a fixed quote before starting. Both. We repair as long as 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'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 failing soon. Replacing the compressor of a nine-year-old unit for a considerable amount, knowing that the electronics and fans are also aging, is generally a poor investment.
