The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to climate control the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for showers and taps. It solves heating, cooling, and hot water needs with a single unit, ideal for chalets and large homes. Amortization compared to a traditional gas + air system takes 8 to 12 years in this area's climate. A complete aerothermal installation is a serious 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.

The electrical check includes the compressor's nominal power consumption during start-up and operation, checking cable insulation, the condition of start capacitors (which degrade after their seventh or eighth year), and verifying the thermostat. The final disinfection with a certified air conditioning product eliminates bacteria, fungi, and odours accumulated in the coil. This is what prevents the characteristic musty smell when you turn 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. 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 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 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. The diagnosis begins with a brief interview with the client about when the problem started, how it manifests, and if anything unusual happened beforehand (storm, unit relocation, impact). It continues with a visual inspection looking for oil stains indicating leaks, visible mechanical damage, or accumulated dirt. Then, electrical measurements are taken, and a refrigerant system analysis is performed using pressure gauges. Once the cause is identified, a fixed quote for the repair is provided, compared against the cost of a new unit if the fault is major.

5-7 years official manufacturer warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day warranty on labour and recommended annual check-ups. Official manufacturer warranty (5-7 years) plus our labour warranty. We arrive with a complete 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 applications to read error codes stored on the control board.

The price for split system installation in Pubilla Cases typically ranges between €148 and €1224. The final amount depends on the property's condition, materials used, and labour time. 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 cost-effective. This is because repairing an expensive component leaves the rest of the unit at its original age. Other components are likely to fail soon. 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 a repair makes economic sense. If it exceeds 60 percent of the price of a new unit, we will inform you, and you can decide.
