Gas leaks, compressor issues, electronics, and sensors. Repair or replacement as appropriate.

Commercial installations above a certain power rating (typically 70 kW thermal) require industrial registration and a project signed by an engineer. For medium-sized premises below this threshold, a certificate signed by an authorised installer is sufficient. In any case, the equipment must have CE marking and comply with European efficiency directives. The F-Gas regulation also applies and mandates the registration of gas charges when they exceed certain kilograms. For the hospitality sector, obtaining a business license may require a climate control certificate issued by the installer. When we work with a new establishment undergoing the licensing process, we coordinate directly with the municipal technician to ensure the climate control paperwork is ready before the final inspection. Professional calculations consider all these factors and correctly size the equipment. The difference in quotes between correctly and incorrectly sized equipment might seem significant initially. The final cost is borne by the customer who visits the shop or restaurant. A poorly air-conditioned space loses customers in summer when the heat becomes unbearable. For hospitality businesses, where customer comfort directly impacts revenue, the right equipment is an investment, not an expense.

Failed electronic boards due to power surges, humidity, or component ageing. 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. 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 price for split system installation in Cervelló typically ranges from €148 to €1224 as an indicative reference. The final figure depends on the property's condition, materials, and labour time, and we always finalise it after seeing photos or — if you prefer — after a site visit, with no obligation. Older models without inverter technology start and stop abruptly at maximum power, which puts more stress on the compressor. Modern inverter models modulate smoothly and last longer. Their electronics are more sensitive, and after seven or eight years, board failures start to appear, requiring the entire module to be replaced. The difference between repairing it and changing the unit depends on the cost of the part versus the price of a comparable new unit. Worn-out compressors in economy range equipment with 6-9 years of intensive use. This is the most expensive fault. Replacing the compressor costs a considerable 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.
