The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to air condition the home. Simultaneously, it heats a domestic hot water tank of approximately 200 litres for showers and taps. It handles everything with a single unit, ideal for villas and large homes. Amortisation compared to a traditional gas + air system takes 8 to 12 years in the local climate. 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 domestic hot water tank and the outdoor unit, and providing a fixed quote.

The electrical inspection includes the compressor's nominal power consumption on start-up and at operating speed, checking the wiring insulation, the condition of the start-up capacitors (which degrade from the seventh or eighth year onwards), and verifying the thermostat. The final disinfection with a certified air conditioning product eliminates bacteria, fungi, and odours accumulated in the coil. This prevents the characteristic damp smell when you switch on the air conditioning after winter. 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 Celsius. 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 provide 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 ranges between 3.5 and 4.5. This means it produces 3.5 to 4.5 kilowatts of heat for every kilowatt of electricity consumed. Diagnosis begins with a brief interview with the client about when the problem started, how it manifests, and if anything unusual happened beforehand (storm, moving the unit, impact). This is followed by a visual inspection for oil stains indicating leaks, visible mechanical damage, and accumulated dirt. Then, electrical measurements and refrigerant analysis using pressure gauges. Once the cause is identified, a fixed quote for the repair is provided, compared with the cost of a new unit if the damage is extensive.

5-7 years official manufacturer warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day cover on labour and recommended annual check-ups. Official manufacturer warranty (5-7 years) plus our labour guarantee. We arrive with a comprehensive set of instruments. Pressure gauges, contact and infrared thermometers, electronic gas leak detector, multimeter, and clamp meter for electrical measurements. We also bring brand-specific diagnostic software to read error codes stored in the control board.

The price for cleaning and maintenance in Coll i Pujol typically ranges between €130 and €1296. The final amount depends on the property's condition, materials used, and time spent. We always provide a fixed quote before starting. As a general rule, if the repair cost exceeds 60 percent of the price of an equivalent new unit, it's not economically viable. This is because repairing an expensive component leaves the rest of the unit at its actual age. Other components will likely fail soon afterwards. Replacing the compressor of a nine-year-old unit for a significant sum, knowing that the electronics and fans are also ageing, is generally a poor investment. Both. We repair whenever the repair makes economic sense. If it exceeds 60 percent of the price of a new unit, we will inform you, and you can decide.
