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 showers and taps. It resolves everything in a single unit, ideal for chalets and large homes. Its payback compared to a traditional gas + air system is 8 to 12 years in the local climate.

The electrical inspection includes nominal compressor consumption on start-up and running, wiring insulation check, condition of start-up capacitors (which degrade from the seventh or eighth year), and thermostat verification. Final disinfection with a certified product for air conditioning eliminates accumulated bacteria, fungi, and odours in the coil. This is what prevents the characteristic musty smell when you turn on the air conditioning after winter. The real economic savings from maintenance are easily calculated. A serious air conditioning breakdown in August, involving compressor replacement or significant leak repair, costs several times the price of annual maintenance over 5 consecutive years. The data from our regular clients confirms that equipment with scheduled maintenance lasts 40 percent longer than equipment with no maintenance at all. The Mediterranean climate of the Costa Blanca is perfectly suited for a modern heat pump. Mild winters, with minimum temperatures between 8 and 16 degrees. Hot summers, but not extreme on the coast. Heat pumps extract energy from the outside air even when temperatures are 4-5 degrees. They use this energy to produce heating in winter, cooling in summer, and domestic hot water. Their efficiency is measured by the COP (Coefficient of Performance), which for a modern pump in this climate is between 3.5 and 4.5. This means it produces 3.5 to 4.5 kilowatts of heat for every kilowatt of electricity consumed.

Official manufacturer's warranty (5-7 years) plus our labour coverage. 5-7 years official manufacturer warranty depending on brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual inspections. For more modern windows with tilt-and-turn profiles and thermal breaks, the hardware is of better quality but also requires maintenance. Lubricating hinges and adjusting locking points every 2-3 years significantly extends their useful life and prevents air ingress in winter or makes them difficult to open.

The price for insulation in El Besòs i el Maresme typically ranges between €208 and €2970. 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 unit 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.
