It starts with calculating the thermal loads of the home, sizing the unit 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. The air-to-water heat pump, also known as aerothermal, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to air-condition the home, and at the same time 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 chalets and large homes. Its payback period compared to a traditional gas + air system is 8 to 12 years in the local climate.

The electrical check includes nominal compressor consumption on startup and during operation, insulation check of the wiring, condition of the start capacitors (which degrade from the seventh or eighth year), and thermostat verification. The final disinfection with a certified air conditioning product eliminates bacteria, fungi, and odours accumulated in the coil. This is what prevents the characteristic damp smell when you turn on the air conditioning after winter. The Mediterranean climate of the Costa Blanca is perfectly suited to 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 it's 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 heat 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. The recharge itself takes 30-45 minutes. But first, the leak must be located and repaired. Without repair, the refrigerant escapes just as quickly, and it's illegal.

5-7 years manufacturer's official warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour guarantee and recommended annual checks. Manufacturer's official warranty (5-7 years) plus our labour guarantee. Common components (remote controls, capacitors, sensors) yes. Electronic boards and compressors are ordered and typically arrive in 2-7 days depending on the brand and model.

The price for cleaning and maintenance in Cerdanyola (Mataró) is typically between €130 and €1296. The final figure depends on the property's condition, materials, and labour time.

As a general rule, if the repair cost exceeds 60 percent of the cost of an equivalent new unit, it's not worth it. The reason is that repairing an expensive component leaves the rest of the unit at its actual age. Other components will likely start failing soon. Replacing the compressor on a nine-year-old unit for a significant sum, knowing that the electronics and fans are also ageing, is generally a poor investment.
