Servicing & Commissioning

Failure to professionally commission and balance an MVHR system can have detrimental effects on its performance and efficiency. Potential issues include condensation problems, increased operational costs, accelerated wear and tear, and non-compliance with building regulations. An unbalanced MVHR system compromises air quality, negating the system’s fundamental purpose. This underscores the critical role of accurate commissioning in ensuring proper ventilation system performance.

Commissioning should be scheduled when the system is fully installed, and the site is relatively clean and dust-free. The visit typically lasts 3-4 hours, depending on factors such as unit size and location. As your installation nears completion, contact our friendly after-sales team at mvhrenquiries@weare21degrees.co.uk to receive a pre-commissioning checklist. We offer nationwide commissioning services and will coordinate a mutually convenient appointment time. Prior to the visit, you will also receive a phone call from your commissioning engineer to address any questions or discuss additional requirements.

We recommend professional servicing by an industry expert annually to ensure effective operation and health benefits. However, if you prefer four-year servicing intervals, it’s your responsibility to perform the following yearly tasks of removing extract valves and cleaning behind them to remove wet dust and towel lint, regularly check and change filters (recommended every 6 months), ensure the condensate drain is clear and verify that intake and exhaust grills are clean and unblocked.

At a minimum, we strongly recommend servicing every four years to ensure ventilation rates are met. Your system’s efficiency and performance are essential for a healthy, comfortable living environment.
