The door closes well but leaves visible gaps between the door and frame, allowing air and noise to pass. This is the natural cycle of wood and can only be avoided by two things: either replacing it with a door made of MDF or multi-layer board which doesn't move, or learning to live with it and adjusting the hinges from time to time. The solar inverter (or microinverter) converts the direct current (DC) from the panels into alternating current (AC) for your home's electrical grid. Optimisers use MPPT tracking techniques to maximise the power of each panel individually, even when connected in series, and transmit data to a central inverter for installation analysis.

The electrical inspection includes the compressor's nominal starting and running current, checking cable insulation, the condition of starting capacitors (which degrade after seven or eight years), and verifying the thermostat. Final disinfection with a certified air conditioning product eliminates bacteria, fungi, and odours accumulated in the coil. This prevents the characteristic musty smell when you turn on the air conditioning after winter. The real economic savings from maintenance are easy to calculate. A serious air conditioning breakdown in August, involving compressor replacement or significant leak repair, costs several times more than annual maintenance over 5 consecutive years. Our client data confirms that equipment with scheduled maintenance lasts 40 percent longer than equipment without any maintenance. This is a very specific pattern for the area. Interior solid wood doors, especially those in 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 properly, rubbing against the top or side of the frame, and forcing it only worsens the hinge.

From €400 for an installed condensing boiler, depending on the brand, power, and necessary work. The replacement cost is usually recovered in 4-6 years through gas savings. Electric underfloor heating for a 90 m² home costs around €4,000 with thermostats per zone. We replace individual radiators for €80-180 each, depending on size and model. A programmable thermostat with installation costs €120-280 depending on the brand. Annual gas boiler maintenance costs between €90 and €130 with a certificate included. Simple repair (sensor, valve, pressure switch) costs €80-180 plus parts. Complete replacement of a natural gas boiler with a condensing model costs €1,400 including installation, depending on brand and power.

The price for insulation in Cervelló typically ranges between €208 and €2,970 as an indicative reference. The final amount depends on the property's condition, materials, and working time, and we always finalise it after seeing photos or —if you prefer— after a visit, with no obligation. If it becomes misaligned again within 30 days for the same reason, we will return at no extra cost.
