Wondering how to keep your heat recovery system in top shape? It is a great question. Proper maintenance is key to maximising the efficiency of your ventilation system, and the good news is it is not complicated — regular cleaning, plus replacing the filters on schedule, does the job.
Despite the importance of ventilation, nearly half of all homeowners neglect to maintain their ventilation systems. We are here to provide the info you need — and if you are left with any questions, don't hesitate to contact us.
So, why bother maintaining your ventilation system?
Think of it like this: your system works hard to exhaust stale air and bring in fresh air from outside. But over time, dust and dirt build up on grilles, filters and valves, contaminating the air that circulates back into your home.
Mechanical parts and ducts can also get clogged with dust, bacteria and even vermin, affecting both air quality and system performance. Keeping your system clean and your filters fresh ensures healthier indoor air and maintains efficiency and longevity.
What maintenance can I handle myself? Here is a simple guide:
- Remove the ventilation grilles from the wall or ceiling and give them a good clean with a brush or vacuum. A damp cloth helps remove stubborn dirt.
- If you have valves, make sure they stay in their optimal position for proper system operation. Mark the position with a waterproof pen before cleaning them with soapy water or a damp cloth.
- For heat recovery systems (MVHR), replace the filters at least every six months — and sooner if they are getting dirty quickly or you suffer from allergies. Note that MVHR filters are designed to be replaced, not cleaned: vacuuming or washing damages the media and reduces their efficiency, so swap them rather than trying to clean them. See how often to change your MVHR filters for more.
That's it. With a little regular attention you can keep your ventilation system running smoothly and your indoor air fresh and clean.
