Keeping Your Mechanical Fan or MVHR Clean: A Guide

Wondering how to keep your heat recovery system in top shape? It's a great question! Proper maintenance is key to maximising the efficiency of your ventilation system. The good news is, it's not too complicated – just regular cleaning will do the trick.

Despite the importance of ventilation, nearly half of all homeowners neglect to clean their ventilation systems. But fear not! We're here to provide you with all the info you need. And if you're left with any questions afterward, don't hesitate to contact us – we're always happy to help.

So, why bother cleaning your ventilation system?

Well, 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. Not ideal, right?

Not only that, but mechanical parts and ducts can also get clogged with dust, bacteria, and even vermin, affecting both air quality and system performance. By keeping your system clean, you're not only ensuring healthier indoor air but also maintaining its efficiency and longevity.

Now, you might be wondering, what maintenance can I handle myself? Here's a simple guide:

  1. Start by removing the ventilation grilles from the wall or ceiling and give them a good clean with a brush or vacuum. A damp cloth can help remove any stubborn dirt.
  2. If you have valves, make sure they stay in their optimal position for proper system operation. You can mark this position with a waterproof pen before cleaning them with soapy water or a damp cloth.
  3. For heat recovery systems (MVHR), remember to replace the filters at least every six months. Give them a gentle vacuum once in a while, but don't overdo it – once they're too dirty, it's time to swap them out. And if you notice them getting dirty sooner or you're experiencing allergies, don't hesitate to replace them sooner.

That's it! With just a little TLC, you can keep your ventilation system running smoothly and your indoor air fresh and clean.
