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 DHW tank and the outdoor unit, and a fixed price quote. 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, while simultaneously heating a domestic hot water tank of approximately 200 litres for showers and taps. It is all resolved in a single unit, ideal for chalets and large homes. Its payback compared to a traditional gas + air system is 8 to 12 years in the local climate.

The real economic savings from maintenance are easy to calculate. A serious air conditioning breakdown in August, involving compressor replacement or significant leak repair, costs several times the price of an annual maintenance service over 5 consecutive years. Our own customer data shows that units with scheduled maintenance last 40 percent longer than units without any maintenance. The electrical check includes nominal compressor consumption on start-up and running, insulation check of wiring, condition of start-up capacitors (which degrade from 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 is what prevents that characteristic damp smell when you turn on the air conditioning after winter. When an air conditioner stops cooling as effectively as before, there can be several causes that initially seem identical. The difference lies in the speed and nature of the failure. If the unit has gradually lost efficiency over months, it's most likely a slow gas leak that has reduced the available amount in the circuit, causing it to malfunction. If the unit was cooling normally and suddenly stopped providing cold air overnight, it's usually a large leak, compressor failure, or a problem with the electronic board. If it starts but stops after a few minutes with an error message on the remote, it could be the thermostat, temperature sensor, or a communication issue between units.

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. Failed electronic board due to power surges, humidity, or component aging. It is relatively common in areas with electrical storms like the Vega Baja interior in August. Repair may involve replacing the entire board or, if identifiable, replacing the specific capacitor or resistor. It depends heavily on the model and parts availability.

The price for split system installation in Centre (L'Hospitalet) typically ranges between €148 and €1224. The final figure depends on the property's condition, materials used, and labour time. We always provide a fixed quote before starting. Worn-out compressor in economy range units with 6-9 years of intensive use. This is the most expensive breakdown. Replacing the compressor costs a significant portion of a new unit's price and is only worthwhile for premium units with a reasonable remaining lifespan. For basic units, we usually recommend replacement. Older models without inverter technology start and stop abruptly at full power, which puts more stress on the compressor. Modern inverter models modulate smoothly and last longer. Their electronics are more sensitive, and from the seventh or eighth year, board failures requiring module replacement start to appear. The decision to repair or replace the unit depends on the cost of the part versus the price of an equivalent new unit.
