If you’ve got a Mechanical Extract Ventilation (MEV) system fitted in your Bradford home, you’ve already got one of the most effective and energy-efficient ways to keep fresh air flowing through your property. MEV systems are designed to quietly extract stale, humid air from multiple rooms and keep condensation and mould at bay — all while running almost silently in the background.
Like any ventilation system, though, your MEV unit needs a bit of attention now and again to keep it performing at its best. As your local extractor and ventilation specialist in Bradford, I carry out MEV servicing and maintenance to make sure your system continues to do its job properly.
Back to top1) What is an MEV system?
An MEV (Mechanical Extract Ventilation) system continuously extracts stale, moist air from rooms like bathrooms, kitchens and utilities using a central fan unit. It’s connected to multiple vents around the home via ducting, pulling out unwanted air and maintaining balanced pressure throughout the property.
Unlike standard extractor fans, MEV systems are always on — running quietly and efficiently to stop condensation, damp, and musty smells from building up. This makes them ideal for modern, airtight homes or properties where traditional fans just don’t do enough.
Back to top2) How do I know if I have an MEV system?
If you’re unsure whether your home has an MEV system fitted, there are a few telltale signs to look for. You’ll usually find a central extraction unit in your loft or a cupboard, with multiple ducts connected to it leading off to different rooms. The unit might have a manufacturer label on the casing — common names include Nuaire, Vent-Axia, or EnviroVent.
If you can find a model number on the unit, a quick online search will tell you whether it’s an MEV system or an MVHR system. If you’re planning to have it serviced, it’s always helpful to let your electrician know the exact make and model before the visit — that way there’s no confusion on pricing or parts when we carry out the work.
Back to top3) Why servicing your MEV system matters
Over time, dust and debris can build up in the ductwork and within the fan housing. This can cause your MEV system to work harder, making it less efficient and noisier than usual. If left too long, it can also reduce airflow and allow humidity to rise — leading to the very problems the system was installed to prevent, like damp and black mould.
Regular servicing ensures your MEV system keeps doing its job efficiently, quietly, and safely. It helps maintain healthy air quality and prevents unnecessary wear on the fan and components.
Back to top4) What’s included in an MEV service
When I service an MEV system, my goal is to make sure it’s clean, efficient, and providing proper airflow throughout your home. Here’s what’s typically included:
- Fan housing and impeller cleaning – Removing dust, lint, and debris to keep the fan running freely.
- Ducting inspection – Checking for blockages or damage that could affect airflow.
- Grille and vent cleaning – Making sure outlets aren’t blocked or restricted.
- Airflow test – Ensuring each room is getting the right extraction rate and balanced airflow.
For systems with adjustable speed controls or humidity sensors, I’ll also make sure they’re operating correctly so the fan only runs as needed, saving energy and noise.
Back to top5) How often should you service your MEV system?
For most homes, I recommend servicing your MEV system every 12 to 18 months. If you live in a larger household, or if you’ve noticed a change in how your ventilation feels — for example, more condensation or unusual noise — it’s a good idea to get it checked sooner.
Keeping up with regular servicing helps your system last longer and keeps it working quietly and efficiently, just as it should.
