In winter, when humidity drops and the dry westerly wind blows, the wood contracts. The door closes well but there's a visible gap between the door and the frame, allowing air and noise to pass through. This is the natural cycle of wood and can only be prevented by two things: either replacing it with an MDF or multi-layered door that doesn't move, or learning to live with it and making occasional hinge adjustments. The air-to-water heat pump, also known as aerothermal heating, goes a 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 resolves everything with a single unit, ideal for chalets and large homes. Its payback compared to a traditional gas + air system is 8 to 12 years in the local climate. A complete aerothermal installation is a serious project. It begins with calculating the thermal loads of the home, sizing the unit 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.

We identify the real cause (dampness, settling, worn hardware) before acting. Traditional knob hinges, found on old construction doors, are not adjustable. If the door rubs, you need to plane wood off or replace the hinges with modern adjustable models. Planing off 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. This is a very specific pattern in the area. Solid wood interior doors, especially those in apartment blocks from the 80s-90s, swell and contract with seasonal humidity changes. In summer, when humidity and temperature are high, the wood absorbs moisture from the air and expands. The door no longer closes well, rubs against the top or side frame, and forcing it only damages the hinge.

For more modern windows with tilt-and-turn profiles and thermal breaks, the hardware is of better quality but also requires maintenance. Lubricating the hinges and adjusting the locking points every 2-3 years considerably extends their lifespan and prevents air from entering in winter or making them too difficult to open.
