For properties that are empty from October to March, the check also includes technical shutdown. We turn off the main water valves if there's no risk of frost, which is rare on the coast. We drain the water heater if the property is unused for more than three months. We empty the air conditioning condensate trays and leave them in the 'off' position. And we check the smoke and carbon monoxide detectors, if present. 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 condition the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for shower and tap use. It solves everything with a single unit, ideal for villas and large homes. Its payback compared to a traditional gas + air system is 8 to 12 years in the local climate. Yes, it's one of our main profiles. Communication via email and WhatsApp, before-and-after photos, and digital invoicing.

Additionally, a visual check of walls and ceilings for damp patches, new cracks, or signs of leaks that may have appeared during the low season. In coastal areas, a specific check of balconies and terraces for corrosion on railings, deterioration of exterior tiling, and the condition of drains to prevent flooding during heavy autumn rains. 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 energy 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 is between 3.5 and 4.5. This means it produces 3.5 to 4.5 kilowatts of heat for every kilowatt of electricity consumed. Yes, but we locate the leak first. Recharging without repairing is illegal and only a temporary fix. If there's a leak, we repair it first, then recharge.

Official manufacturer's warranty (5-7 years) plus our coverage on labour. 5-7 years official manufacturer warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual checks. We arrive with a complete set of instruments. Gauges for pressure, contact and infrared thermometers, electronic gas leak detector, multimeter, and clamp meter for electrical measurements. We also carry the specific diagnostic app for each brand to read error codes stored on the circuit board.

The price for split AC installation in Sant Martí de Provençals typically ranges between €148 and €1224. The final amount depends on the property's condition, materials, and work time. We always provide a fixed quote before starting. The cost of scheduled maintenance is always less than the accumulated cost of reactive emergencies. The data we have from our own clients confirms this year after year. Yes, we offer an annual contract with two scheduled visits plus urgent response for the rest of the year at a preferential rate.
