It begins with calculating the thermal loads of the home, 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 a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to regulate the home's climate, and at the same time heats a domestic hot water tank of approximately 200 litres for showers and taps. It solves everything with 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 area's climate.

Traditional knob hinges, those found on old built-in doors, are not adjustable. If the door rubs, you need to plane the wood or replace the hinges with modern adjustable models. Planing the 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 properly again. This is a very specific pattern in the area. Solid wood interior doors, especially those in blocks from the 80s-90s, swell and contract with seasonal changes in humidity. In summer, when humidity and temperature are high, the wood absorbs water from the air and expands. The door stops closing properly, rubs against the top or side frame, and forcing it closed only worsens the hinge. In winter, when humidity drops and dry westerly winds blow, 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 with MDF or multi-layered doors that do not have this movement, or learn to live with it and adjust the hinges as needed.

5-7 years official manufacturer's warranty depending on brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day coverage on labour and recommended annual inspections. 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 hinges and adjusting closing points every 2-3 years significantly extends their lifespan and prevents air ingress in winter or them being too difficult to open.
