A new electrical installation during a full renovation or new construction is more than just wiring walls. It's a project that starts with calculating expected loads: how many appliances, their power ratings, special circuits for air conditioning or induction cooktops. Then it moves to sizing the electrical panel and cables, followed by the physical wiring. It concludes with legalisation before the electricity distributor. We arrive with a full set of instruments: pressure gauges, contact and infrared thermometers, electronic gas leak detectors, multimeters, and clamp meters for electrical measurements. We also carry brand-specific diagnostic applications 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, equipment 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 pressure 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 damage is extensive.

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 less, even if the unit is running. Gas leak at the outdoor unit's connection, especially in units over 5 years old. Salt spray and seasonal temperature changes loosen the connections. A small leak progressively reduces the charge, and the unit cools less effectively each season. Repair involves detection with a professional gas detector, replacing the connection or re-soldering the copper, vacuuming, and recharging. Burned-out compressor in budget-range units with 6-9 years of intensive use. This is the most expensive failure. Replacing the compressor costs a significant portion of a new unit's price and is usually only worthwhile for premium units with a reasonable remaining lifespan. For basic units, we normally recommend replacement.

For premium units from recognised brands (Mitsubishi, Daikin, LG) aged 10-12 years, repair is often still worthwhile because the overall quality justifies extending their lifespan. For basic units aged 7-8 years, replacement is almost always the reasonable decision. Official manufacturer's warranty on materials (3-10 years depending on manufacturer) and our 30-day warranty on labour. The certificate legalises the installation. Mitsubishi, Daikin, LG, Toshiba, Samsung, Panasonic, Fujitsu, Hitachi, Hisense, and others. For official warranty claims, we refer you to the brand's authorised service centre.

The price for gas charging in Vista Alegre (Mataró) 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. As a general rule, if the repair exceeds 60 percent of the cost of an equivalent new unit, it's not cost-effective. This is because repairing an expensive component leaves the rest of the unit at its actual age. Other components will likely start failing soon. Replacing the compressor in a nine-year-old unit for a considerable amount, knowing that the electronics and fans are also aging, is generally a poor investment.
