MVHR systems provide continuous fresh air and energy savings, but they require regular maintenance to function effectively. A poorly maintained system can lead to reduced airflow, poor heat recovery, and increased running costs. Homeowners often overlook simple maintenance tasks that can extend the life of their MVHR unit and improve indoor air quality.
MVHR systems provide continuous fresh air and energy savings, but they require regular maintenance to function effectively. A poorly maintained system can lead to reduced airflow, poor heat recovery, and increased running costs. Homeowners often overlook simple maintenance tasks that can extend the life of their MVHR unit and improve indoor air quality.
As UK homes become more insulated and airtight, maintaining healthy indoor air quality is crucial. A well-maintained MVHR system can recover up to 95% of heat, reducing heating costs while preventing condensation and dampness. However, without regular servicing, homeowners may experience:
A family in Oxford noticed their energy bills rising and stale air lingering despite having an MVHR system. Upon inspection, their filters were completely blocked, and airflow had reduced by 40%. After a full system clean and filter replacement, efficiency improved, and heating costs dropped by 25%.
A well-maintained MVHR system can last 20–25 years, while a neglected system may need replacing in 10–12 years, leading to unnecessary expenses. Regular maintenance can also reduce heating bills by up to 30%.
