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 use in showers and taps. It resolves everything in a single unit, ideal for chalets and large homes. Amortisation compared to a traditional gas + air system is between 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 working with a new premises undergoing the licensing process, we coordinate directly with the municipal technician to ensure the 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 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 kilogram limits. Commercial equipment operates under much more demanding conditions than domestic units. 12-14 hours of daily operation during peak season, variable thermal loads throughout the day, accumulated dirt from higher air flow. Without proper maintenance, a breakdown during the peak season for a commercial premises costs not only the repair but also lost revenue from hours or days without service.

Manufacturer's official warranty (5-7 years) plus our labour coverage. 5-7 years manufacturer's warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour coverage and recommended annual check-ups. Electronic board failure due to power surges, humidity, or component aging. This is relatively frequent in areas with electrical storms, like the interior of Vega Baja in August. Repair may involve replacing the entire board or, if identifiable, replacing a specific capacitor or resistor. Much depends on the model and parts availability.

The price for split system installation in Cerdanyola (Mataró) typically ranges between €148 and €1224. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. A complete aerothermal installation is a serious 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 DHW tank and outdoor unit, and providing a fixed quote.
