The outdoor unit heats or cools water circulating through radiators, underfloor heating, or fan coils to air condition the home, and simultaneously heats an approximately 200-litre domestic hot water tank for showers and taps. It solves everything with a single unit, ideal for chalets and large homes. Payback compared to a traditional gas + air system is 8 to 12 years in the local climate. A complete aerothermal installation is a serious project. It starts with calculating the home's thermal loads, sizing the unit based on actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the DHW tank and outdoor unit, and a fixed quote.

The electrical check includes nominal compressor consumption at startup and running, insulation check of the wiring, condition of the start capacitors (which degrade after 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 prevents the characteristic musty smell when you turn on the air conditioning after winter. The Mediterranean climate of the Costa Blanca perfectly suits 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 it 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. Between 30 minutes and 2 hours depending on complexity. A simple fault is identified quickly. Small leaks or electronic issues may require more time.

5-7 years from the manufacturer depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual checks. Official manufacturer warranty (5-7 years) plus our coverage on labour. For premium equipment from recognised brands (Mitsubishi, Daikin, LG) that are 10-12 years old, repair often still makes sense because the overall quality justifies extending its useful life. For basic equipment that is 7-8 years old, replacement is almost always the sensible decision.

The price for cleaning and maintenance in Barcelona typically ranges between €130 and €1296. The final amount depends on the property's condition, materials, and working time. We always provide a fixed quote before starting. Both. We always repair if the repair makes economic sense. If it exceeds 60 percent of the price of new equipment, we'll tell you, and you can decide. 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 equipment at its actual age. Other components will start to fail soon. Replacing the compressor of a nine-year-old unit for a significant amount, knowing that the electronics and fans are also aging, is generally a bad investment.
