It begins with calculating the thermal loads of the property, sizing the equipment according to actual 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 air-to-water heat pump, also called aerothermal, goes one step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to air-condition 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 chalets and large homes. Its payback period compared to a traditional gas + air system is 8 to 12 years in the local climate.

This is a very specific pattern in the area. Interior solid wood doors, especially those in 1980s-1990s blocks, swell and contract with seasonal humidity changes. In summer, when there is high humidity and high temperature, the wood absorbs water from the air and expands. The door stops closing properly, rubs against the top frame or the side, and forcing it closed only worsens the hinge. In winter, when humidity drops and dry westerly winds come in, the wood contracts. The door closes well but there is a visible gap between the door and frame, allowing air and noise to pass through. This is the natural cycle of wood and can only be avoided in two ways: either replace it with an MDF or multi-layered door that does not move, or learn to live with it and adjust the hinges as needed. Traditional knob hinges, those found on old construction doors, are not adjustable. If the door rubs, wood must be planed down or hinges replaced with modern adjustable models. Planing wood is the usual solution when the problem is seasonal. We remove 1-2 mm from the rubbing area, seal the cut, and the door closes again.

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 fittings are of better quality but also require maintenance. Lubricating the hinges and adjusting the closing points every 2-3 years significantly extends their lifespan and prevents air from entering in winter or them becoming too difficult to open. 30 days on the repair.
