The outdoor unit heats or cools water circulating through radiators, underfloor heating, or fan coils to air condition the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for use in showers and taps. It handles everything with a single unit, ideal for villas and large homes. Its payback period compared to a traditional gas + air system is 8 to 12 years in the local climate.

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, equipment must have CE marking and comply with European efficiency directives. The F-Gas Regulation also applies, requiring registration of gas charges exceeding certain weight limits. Professional calculation considers all these factors and correctly sizes the equipment. The difference in quote between correctly and incorrectly sized equipment may seem significant at first. The final cost is borne by the end customer visiting 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 determines revenue, the right equipment is an investment, not an expense. Commercial units operate under much more demanding conditions than domestic ones: 12-14 hours daily in high season, variable thermal loads throughout the day, accumulated dirt from higher air flow. Without proper maintenance, a breakdown during peak season for a commercial premises costs not only the repair but also lost revenue due to hours or days of service interruption.

Official manufacturer warranty (5-7 years) plus our labour guarantee. 5-7 years official manufacturer warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day guarantee on labour and recommended annual servicing. Electronic board failure due to power surges, humidity, or component ageing. This is relatively common in areas with electrical storms, such as the interior of the 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.

The cost of split system installation in Collblanc typically ranges from €148 to €1224. The final price depends on the property's condition, materials used, and time required. We always provide a fixed quote before starting. A complete aerothermal installation is a significant project. It starts with calculating the home's thermal load, sizing the equipment according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the hot water tank and outdoor unit, and providing a fixed quote.
