The outdoor unit heats or cools water that circulates 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 showers and taps. It resolves everything with a single unit, ideal for detached houses and large homes. Its amortisation compared to a traditional gas + air system is 8 to 12 years in the local climate.

For hospitality businesses, obtaining an operating license may require an air conditioning certificate issued by the installer. When we work with a new venue in the licensing process, we coordinate directly with the municipal technician to ensure all air conditioning 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 venues below this threshold, a certificate signed by an authorised installer is sufficient. In any case, the equipment must bear the CE mark and comply with European efficiency directives. The F-Gas Regulation also applies and mandates registration of refrigerant charges exceeding certain kilograms. Commercial equipment operates under much more demanding conditions than domestic units. 12-14 hours of daily operation in high season, variable thermal loads throughout the day, accumulated dirt from higher air flow. Without adequate maintenance, a breakdown during peak season for a commercial venue costs not only the repair but also lost revenue from hours or days of service interruption.

Official manufacturer warranty (5-7 years) plus our labour coverage. 5-7 years manufacturer warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual checks. Failed electronic boards due to power surges, moisture, or component aging. This is relatively common in areas with electrical storms, such as the interior of Vega Baja in August. Repair may involve replacing the entire board or, if identifiable, replacing the specific capacitor or resistor. It depends heavily on the model and parts availability.

The price for cleaning and maintenance in Cerdanyola del Vallès typically ranges from €130 to €1296. The final amount depends on the property's condition, materials, and working time. We always provide a fixed quote before starting. A complete aerothermal installation is a significant project. It begins with calculating the home's thermal loads, sizing the equipment according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the domestic hot water tank and outdoor unit, and a fixed quote.
