What happens during a maintenance visit?
That depends on the installation type. Think filter checks, efficiency measurement, safety inspection and functional test. See our pages per type for details.
During a maintenance visit we check and clean your installation according to a fixed checklist — tailored to the system type. For AC: filters, refrigerant, drain pan, outdoor unit and functional test. For CV-ketel: safety, combustion, efficiency, water pressure and flue gas. For heat pump: pressure, filters, outdoor unit, performance and electrical connections. Afterwards you receive a report with findings and advice.
