MVHR Servicing

A heat recovery system recovers heat and energy otherwise lost from your property. It can recover up to 90% of normally wasted heat and reduce your heating requirements by up to 25%. It also improves your indoor air quality by providing an air change with fresh filtered air. Manufacturers state that a service should be completed on an annual basis in order to comply with their warranty terms and to prevent fan failure. Filters should be checked and changed more frequently to ensure that the filters are not so dirty that they are blocking the airflow or allowing dirt to pass through.

Why is it important to have my MVHR system serviced annually?

Servicing a Mechanical Ventilation with Heat Recovery (MVHR) system is crucial for several reasons.

Book a Service

1. Ensures Optimal Performance

  • Regular servicing keeps the system running efficiently, ensuring proper ventilation and heat recovery.
  • Helps maintain energy efficiency, reducing energy consumption and lowering utility bills.

2. Preserves Indoor Air Quality

  • Filters in MVHR systems capture dust, pollen, and other pollutants. Over time, they clog and need cleaning or replacement to prevent poor air circulation.
  • A neglected system can reintroduce allergens and pollutants into the air, affecting occupants' health.

3. Prevents System Damage

  • Dust and debris buildup in ducts, fans, or heat exchangers can strain the system, potentially leading to breakdowns or reduced lifespan.
  • Servicing identifies early signs of wear or damage, preventing costly repairs.

4. Reduces Noise Levels

  • A poorly maintained MVHR system can become noisy due to clogged filters or mechanical issues.
  • Regular servicing ensures quiet and smooth operation.

5. Meets Warranty Requirements

  • Many MVHR manufacturers require routine servicing to keep warranties valid.
  • Lack of maintenance could void the warranty, leaving you liable for repairs.

6. Promotes Energy Savings

  • Heat recovery efficiency decreases when the system isn't maintained, leading to higher energy usage.
  • Cleaning and servicing ensure maximum heat recovery performance.
