The air-to-water heat pump, also called 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 showers and taps. It handles everything in 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. A complete aerothermal installation is a serious project. It starts 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 hot water tank and outdoor unit, and a fixed quote.

The electrical check includes the compressor's nominal consumption on start-up and running, checking the wiring insulation, the condition of the start capacitors (which degrade from the seventh or eighth year), and verifying the thermostat. 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 real economic savings from maintenance are easy to calculate. A serious air conditioning breakdown in August, involving compressor replacement or major leak repair, costs several times more than annual maintenance over 5 consecutive years. Data from our own clients confirm that equipment with scheduled maintenance lasts 40 percent longer than equipment without any maintenance. Yes, but we locate the leak first. Recharging without repairing is illegal and a temporary fix. If there's a leak, we repair it first, then recharge.

Official manufacturer's warranty (5-7 years) plus our labour coverage. 5-7 years manufacturer's official warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour coverage and recommended annual check-ups. Electronic board failure due to power surges, moisture, or component aging. It's relatively common in areas with electrical storms like the interior of Vega Baja in August. Repair can involve replacing the entire board or, if identifiable, replacing a specific capacitor or resistor. It depends heavily on the model and parts availability.

The price for split system installation in Provençals del Poblenou typically ranges between €148 and €1224. The final figure depends on the property's condition, materials, and labour time. We always provide a fixed quote before starting. Call us, message us on WhatsApp, or request your quote online — we'll respond in under 10 minutes during business hours. Older models without inverter technology start and stop abruptly at maximum power, which stresses the compressor more. Modern inverter models modulate smoothly and last longer. Their electronics are more sensitive, and from the seventh or eighth year, board failures start to appear, requiring the replacement of the entire module. The decision between repairing it or replacing the unit depends on the cost of the part versus the price of a comparable new unit.
