Top 5 Signs Your MVHR System Needs Maintenance in Basingstoke

Top 5 Signs Your MVHR System Needs Maintenance

1. Reduced Airflow or Weak Ventilation
   • If you notice weak airflow from vents, your MVHR system may have blocked filters, duct obstructions, or a failing fan motor.
   • Solution: Clean or replace filters every 3–6 months and check for airflow blockages.
2. Unusual Noises from the System
   • Humming, rattling, or whistling sounds indicate potential loose components, motor wear, or airflow restrictions.
   • Solution: Have a professional inspect the system to tighten components and clear obstructions.
3. Increase in Energy Bills
   • A sudden spike in energy usage may mean your heat exchanger is clogged or airflow is restricted, causing the system to work harder.
   • Solution: Ensure filters, vents, and the heat exchanger are clean to maintain efficiency.
4. Condensation or Mould Growth in Your Home
   • If condensation appears on windows or mould develops on walls, your MVHR system may not be effectively controlling humidity.
   • Solution: Check airflow balance settings and inspect ducting for leaks or blockages.
5. Unpleasant Odours or Stale Air
   • Musty or stale smells indicate clogged filters, bacterial buildup, or poor air circulation.
   • Solution: Replace filters and schedule professional cleaning every 2–3 years.

Long-Term Cost & Energy Savings

Regular maintenance ensures your MVHR system remains energy-efficient, potentially saving homeowners £250–£500 per year in reduced heating costs. A neglected system, however, can lead to higher energy bills and costly repairs over time.

‍

Maintenance & Best Practices

• Replace filters at least every 6 months to prevent airflow blockages.
• Inspect and clean ducting every 2–3 years to remove dust buildup.
• Monitor system noise levels and airflow balance to detect early warning signs.
• Book professional servicing every 2–5 years to maintain long-term efficiency.
