It starts with calculating the thermal loads of the home, 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 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 climate control the home, and at the same time heats a domestic hot water tank of approximately 200 litres for showers and taps. It solves everything in a single unit, ideal for detached houses and large homes. Its payback period compared to a traditional gas + air system is 8 to 12 years in the local climate.

A popular improvement today is combining a motorised blind with a roll-up mosquito net integrated into the same box. This allows both the blind and the mosquito net to operate independently, both hidden when not in use. It's the standard solution in modern new builds. For renovations of existing homes, it requires replacing the entire box with a new, deeper one that houses both systems. Motorisation requires electrical power to the upper box. If the box wall already has an electrical cable nearby (typically from the nearest room power outlet), installation is straightforward. If not, the cable must be routed via an external conduit or a hidden channel. The complete motorisation operation takes 2-3 hours per blind when power is nearby. For all blinds in an entire house, we can do it in 1-2 days. The strap replacement itself is a 30-45 minute operation per blind when the box is accessible. The real complexity lies in locating the internal break, opening the box without damaging it, removing the axle, taking out the old strap, feeding the new one through the slats and the winder. Reassembling the entire unit without misaligning the slats. For someone who has never done it, a blind can take three hours and end up worse than before. For technicians who do it daily, it's a 30-minute job with a clean result.

If the blind slats are cracked, discoloured, and brittle (typical for blinds more than 25-30 years old exposed to the sun), repairing them point by point becomes economically senseless. Replacing the entire blind with a modern model costs two to three times more than just changing the strap. In return, it gives you another 25-30 years of trouble-free operation. Modern slats are injected and filled with polyurethane, much more insulating than old hollow ones, thus improving thermal insulation. And you can order integrated motorisation from the factory. Official manufacturer's warranty (5-7 years) plus our coverage on labour. For more modern windows with tilt-and-turn profiles and thermal break, the hardware is of better quality but also requires maintenance. Lubricating the hinges and adjusting the closing points every 2-3 years significantly prolongs their lifespan and prevents air from entering in winter or them becoming too difficult to open.

The price of insulation in El Carmel usually ranges between €208 and €2970. The final figure depends on the condition of the property, the materials, and the labour time.

If it becomes misaligned again within 30 days for the same reason, we will return at no extra cost.
