The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to climatise the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for use in showers and taps. It solves everything with a single unit, ideal for chalets and large homes. Amortisation 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, 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. Professional calculation considers all these factors and correctly sizes the equipment. The price difference between a well-sized and a poorly-sized unit may seem significant at first. The final cost is ultimately paid 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 the hospitality sector, where customer comfort directly determines turnover, the right equipment is an investment, not an expense. Commercial units operate under much more demanding conditions than domestic ones. 12-14 hours of daily operation during peak season, variable thermal loads throughout the day, accumulated dirt from higher airflow. Without proper maintenance, a breakdown during high season in a commercial premises costs not only the repair but also lost revenue from hours or days of service interruption.

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 coverage on labour and recommended annual check-ups. Electronic board failure due to power surges, humidity, or component ageing.

The price for split system installation in Sant Gervasi - la Bonanova typically ranges between €148 and €1,224. The final figure depends on the property's condition, materials used, and time taken. 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 the outdoor unit, and providing a fixed quote.
