For hospitality businesses, obtaining a business operating license may require a climate control certificate issued by the installer. When we work with a new establishment during the licensing process, we coordinate directly with the municipal inspector to ensure the climate control paperwork is ready before the final inspection. Commercial installations above a certain power threshold (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 all cases, equipment must have CE marking and comply with European efficiency directives. The F-Gas Regulation also applies, requiring registration of refrigerant charges exceeding certain weights. Professional calculations consider all these factors and correctly size the equipment. The difference in quote between correctly and incorrectly sized equipment might seem significant at first. The true cost is ultimately borne by the customer who visits the shop or restaurant. A poorly air-conditioned premises loses customers in the summer when the heat becomes unbearable. For hospitality, where customer comfort directly impacts revenue, the right equipment is an investment, not an expense.

Electronic board failure due to power surges, humidity, or component aging. This is relatively common in areas with electrical storms, such as the inland Vega Baja in August. Repair might 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 Sarrià typically ranges between €148 and €1224. 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, putting more strain 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 begin to appear, requiring replacement of the entire module. The decision to repair or replace the unit depends on the cost of the part versus the price of a new equivalent unit. Compressor failure in economy-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 units with a reasonable residual lifespan. For basic units, we usually recommend replacement.
