The air-to-water heat pump, also known as aerothermal heating, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to climatise the home. Simultaneously, it heats a domestic hot water tank of approximately 200 litres for showers and taps. It solves everything with a single unit, ideal for villas and large homes. Its payback compared to a traditional gas heating + air conditioning system is 8 to 12 years in the local climate. A complete aerothermal installation is a serious project. 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 domestic hot water tank and outdoor unit, and providing a fixed quote.

The electrical inspection includes the nominal consumption of the compressor during startup and operation, checking the insulation of the wiring, the condition of the start capacitors (which degrade from the seventh or eighth year), and verifying the thermostat. The final disinfection with a certified product for air conditioning eliminates bacteria, fungi, and odours accumulated in the coils. This is what prevents the characteristic musty smell when you turn on the air conditioning after winter. The real economic savings of maintenance are easy to calculate. A serious air conditioning breakdown in August, involving compressor replacement or a significant leak repair, costs several times more than annual maintenance over 5 consecutive years. Our own client data confirms that units with programmed maintenance last 40 percent longer than units 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 warranty (5-7 years) plus our labour coverage. 5-7 years manufacturer's warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual check-ups. Electronic board failure due to power surges, moisture, or component aging. This is relatively common in areas with thunderstorms, like the interior of Vega Baja in August. Repair may involve replacing the entire board or, if identifiable, replacing specific capacitors or resistors. It largely depends on the model and parts availability.

The price for split system installation in Vallbona typically ranges between €148 and €1224. The final amount 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 reply 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 onwards, board failures start to occur that require replacing the entire module. The difference between repairing it or replacing the unit depends on the cost of the part versus the price of a comparable new unit.
