Modern airtight homes rely heavily on efficient ventilation to maintain comfort and indoor air quality, making regular servicing of an Mechanical Ventilation with Heat Recovery system essential. MVHR technology is designed to continuously extract stale air from wet rooms such as kitchens and bathrooms while delivering filtered fresh air into living MVHR service spaces. At the same time, it captures heat from outgoing air and transfers it to incoming air, reducing energy waste and supporting a stable indoor climate throughout the seasons
Over time, even the most advanced systems require attention to ensure they continue performing at their best. Dust, debris, and airborne pollutants gradually collect within filters and ductwork. If left unchecked, these accumulations restrict airflow and reduce the system’s efficiency. Professional MVHR service addresses this issue by inspecting and replacing filters where necessary, restoring balanced ventilation and protecting the overall health of the system
A thorough service appointment typically includes detailed examination of the heat exchanger core. This component plays a critical role in recovering warmth from extracted air, and any buildup of dirt can limit its ability to transfer heat effectively. Cleaning and inspecting the heat exchanger helps maintain energy efficiency and prevents unnecessary strain on the fans and motors. Technicians also evaluate the condition of internal components, ensuring that moving parts operate smoothly and quietly
Airflow balancing is another vital element of MVHR maintenance. Each room in a property requires a specific ventilation rate to prevent condensation and maintain comfort. During servicing, airflow measurements are taken and adjusted if required. Proper calibration ensures that fresh air supply and stale air extraction remain in harmony, supporting consistent performance across the entire building. This step is particularly important in modern homes built to high insulation standards where natural air leakage is minimal
In addition to mechanical checks, professional service includes inspection of condensate drains and duct connections. Blocked drains can lead to moisture buildup, while loose or damaged ductwork may result in energy loss or reduced air quality. Addressing these issues early helps prevent costly repairs and extends the lifespan of the system. Electrical components and control panels are also tested to confirm safe operation and correct programming
Routine servicing delivers measurable benefits beyond system longevity. Clean filters and properly balanced airflow contribute to healthier indoor air by reducing allergens, pollutants, and excess humidity. Improved heat recovery efficiency lowers heating demand during colder months, supporting reduced energy consumption and environmental impact. In the long term, consistent maintenance preserves the original performance standards set during installation
Homeowners are generally encouraged to schedule professional MVHR service annually, although filter checks may be needed more frequently depending on occupancy levels and external air conditions. Properties in areas with high pollution or construction activity may require additional attention. Establishing a maintenance routine ensures that minor issues are identified before they develop into larger concerns
Investing in regular MVHR servicing protects both comfort and efficiency. By keeping components clean, airflow balanced, and controls properly calibrated, homeowners can rely on steady ventilation and energy savings year round. In well insulated buildings where ventilation plays a critical role in maintaining a healthy environment, dependable MVHR maintenance remains an indispensable part of responsible property care
