Locating and repairing leaks, replacing parts, or recharging gas based on diagnosis. Professional diagnosis when your air conditioning doesn't cool as it used to. Gas leaks, compressor issues, electronic faults, and sensor problems. Repair or replacement as appropriate. Diagnosis begins with a brief interview with the client about when the problem started, how it manifests, and if there was anything unusual 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, you'll receive a fixed quote for the repair, compared against the cost of new equipment if the fault is significant.

Compressor failure in budget-range units after 6-9 years of intensive use. This is the most expensive repair. Replacing the compressor costs a significant portion of a new unit's price and is only worthwhile for premium equipment with reasonable remaining lifespan. For basic units, we usually recommend replacement. Gas leak in the outdoor unit fitting, especially common in units over 5 years old. Salt air and seasonal temperature changes (summer-winter) can loosen fittings. A small leak gradually reduces the charge, causing the unit to cool less effectively each season. Repair involves detection with a professional gas detector, replacing the fitting or re-soldering the copper pipe, vacuuming, and a new charge. When an air conditioner stops cooling as it used to, there can be several causes that appear similar at first glance. The difference lies in the speed and nature of the failure. If the unit has gradually lost efficiency over months, it's most likely a slow gas leak that has progressively reduced the available refrigerant in the circuit, causing it to malfunction. If the unit was cooling normally and suddenly stopped producing cold overnight, it's usually a large leak, compressor failure, or a problem with the electronic board. If it starts but stops after a few minutes with an error message on the remote, it could be a thermostat, temperature sensor, or a communication issue between units.

For premium units from recognised brands (Mitsubishi, Daikin, LG) aged 10-12 years, repair is usually still worthwhile because the overall quality justifies extending their lifespan. For basic units aged 7-8 years, replacement is almost always the sensible decision. We arrive with a complete 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 apps to read error codes stored in the control board. Common components (remote controls, capacitors, sensors) yes. Electronic boards and compressors are ordered and arrive in 2-7 days depending on the brand and model.

The cost for gas recharging in Pubilla Cases generally 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. Older models without inverter technology start and stop abruptly at full power, putting 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 onwards, board failures requiring the entire module to be replaced begin to appear. The decision to repair or replace the unit depends on the cost of the part versus the price of an equivalent new unit. 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.
