Connect your system to IoT platforms such as Ecoforest Smart to receive notifications of faults.<\/li>\n\n\n\n<li><b>Document each service<\/b>: Request detailed technical reports with pressure, temperature and consumption measurements.<\/li>\n\n\n\n<li><b>Combine with renewable energies<\/b>: Install <a href=\"https:\/\/ecoforest.com\/en\/bomba-de-calor\/\">photovoltaic panels<\/a> to reduce electricity costs by up to 70%.<\/li>\n\n\n\n<li><b>Demand certifications<\/b>: Only hire technicians with <b>RITE<\/b> and <b>Fluorinated Gas Handler<\/b> licences.<\/li>\n\n\n\n<li><b>Take advantage of subsidies<\/b>: In 2025, the <b>REPowerEU Plan<\/b> will cover up to 40% of the maintenance costs for hybrid systems.<\/li>\n<\/ol>\n\n<h2 class=\"wp-block-heading\" id=\"cundo-requieren-mantenimiento-profesional\">When do they require professional maintenance?<\/h2>\n\n<ul class=\"wp-block-list\">\n<li><b>Geothermal<\/b>: If the COP drops below 3.5 or there are fluctuations &gt;2\u00b0C in the indoor temperature.<\/li>\n\n\n\n<li><b>Aerothermal<\/b>: If the outdoor unit emits metallic noises or consumption increases &gt;20% without a change in
