Locating and repairing leaks, replacing parts, or recharging gas based on diagnosis. 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 brand-specific diagnostic software to read error codes stored on the circuit board. The 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). It continues with 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 new equipment if the fault is major.

Fault located with certified instruments before proposing a repair. When an air conditioner stops cooling as it used to, several causes are possible, and they may seem similar at first glance. The difference lies in the speed and manner of the failure. If the unit has gradually lost efficiency over months, it's likely a slow gas leak that has reduced the available amount in the circuit, causing it to work poorly. If the air conditioner was cooling normally and suddenly stopped providing cold air overnight, it's usually a large leak, compressor failure, or an electronic board issue. If it starts but stops after a few minutes with an error message on the remote, it could be the thermostat, temperature sensor, or a communication problem between units. Gas leak at the outdoor unit fitting, especially in equipment over 5 years old. Salt spray and thermal expansion/contraction cycles in summer and winter loosen the fittings. 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 pipe, vacuuming, and recharging.

Faulty electronic board due to power surge, moisture, or component aging. This is relatively common in areas with electrical storms, like the inland 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. For premium brands like Mitsubishi, Daikin, or LG that are 10-12 years old, repair often still makes sense because the overall quality justifies extending its lifespan. For basic models that are 7-8 years old, replacement is almost always the reasonable decision. Mitsubishi, Daikin, LG, Toshiba, Samsung, Panasonic, Fujitsu, Hitachi, Hisense, and others. For official warranty, we direct you to the brand's authorized service.

The cost for heat pump service in Vista Alegre (Mataró) typically ranges between €160 and €1440. The final amount 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 full 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, board failures start to appear, requiring the entire module to be replaced. The decision between repairing it or changing the unit depends on the cost of the part versus the price of a comparable new unit. Worn-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 is only worthwhile for premium equipment with a reasonable remaining lifespan. For basic units, we usually recommend replacement.
