A complete aerothermal installation is a serious project. It begins with calculating the thermal loads of the home, sizing the equipment 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 providing a fixed 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 climatise the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for use in showers and taps. It's an all-in-one solution, ideal for chalets and large homes. 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, requiring compressor replacement or significant leak repair, costs several times more than annual maintenance over 5 years. Our own customer data confirms that equipment with scheduled maintenance lasts 40 percent longer than equipment without any maintenance. The electrical check includes nominal compressor power consumption on start-up and at operating speed, insulation resistance check of the wiring, condition of the start-up capacitors (which degrade after the seventh or eighth year), and thermostat verification. Final disinfection with a certified air conditioning product eliminates bacteria, fungi, and odours accumulated in the coil. This prevents the characteristic musty 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 seem similar at first glance. The difference lies in the speed and manner of the failure. If the air conditioner has gradually lost efficiency over months, a slow refrigerant leak is the most likely cause, reducing the available amount in the circuit until it operates poorly. If the air conditioner was cooling normally and suddenly stopped providing cold from one day to the next, it's usually a large leak, compressor failure, or a problem with the electronic board. If it starts but shuts off 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 warranty (5-7 years) plus our labour coverage. 5-7 years manufacturer warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour coverage and recommended annual checks. Failed electronic board due to power surges, moisture, or component aging. This is relatively common in areas with thunderstorms like the Vega Baja inland in August. Repair may 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 El Guinardó 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. Burned-out compressor in budget-range equipment with 6-9 years of intensive use. This is the most expensive breakdown. Replacing the compressor costs a significant portion of a new unit and only makes sense for premium equipment 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 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, circuit board failures requiring replacement of the entire module start to appear. The difference between repairing it or replacing the unit depends on the cost of the part versus the price of an equivalent new unit.
