It starts with calculating the property's thermal loads, sizing the equipment according to real needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the domestic hot water tank and outdoor unit, and a fixed quote.

The real economic savings from maintenance are easy to calculate. A serious air conditioning breakdown in August, with compressor replacement or major leak repair, costs several times what annual maintenance costs for 5 consecutive years. Our own client data confirms that equipment with scheduled maintenance lasts 40 percent longer than equipment without any maintenance. Electrical inspection includes nominal compressor consumption at start-up and during operation, wiring insulation check, condition of starting capacitors (which degrade after the seventh or eighth year), and thermostat verification. Final disinfection with a certified climate control product eliminates bacteria, fungi, and odours accumulated in the coil. This is what prevents the characteristic damp smell when you start the air conditioning after winter. The Mediterranean climate of the Costa Blanca perfectly suits a modern heat pump. Mild winters, between 8 and 16 degrees minimum. 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 it to produce heating in winter, cooling in summer, and domestic hot water. Their performance 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.

Official manufacturer's warranty (5-7 years) plus our labour coverage. 5-7 years official manufacturer's warranty depending on brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour coverage and recommended annual inspections. For more modern windows with tilt-and-turn profiles and thermal break, the hardware is of better quality but also requires maintenance. Lubricating hinges and adjusting closing points every 2-3 years significantly prolongs their lifespan and prevents air ingress in winter or difficulty opening.

The price of insulation in Castelldefels usually ranges between 208 and 2970 euros. The final figure depends on the property's condition, materials, and work time.
