How Often Should You Service Your Extractor Fan? Advice from Bradford’s Specialist

Many homeowners in Bradford aren’t sure when their fans need attention — they usually only think about it once it starts getting noisy, losing power, or when condensation starts appearing again.

As your local extractor fan and ventilation specialist, I’m here to help make it clear. Regular servicing is the key to keeping your home free from damp, mould and stale air, and it doesn’t need to be complicated.

1) Why extractor fan servicing matters

Extractor fans work hard behind the scenes, keeping your home free from moisture and stale air. Over time, dust, grease and dirt can build up inside the unit. That build-up can make the fan noisy, slow it down, and even cause it to fail completely.

Servicing your extractor fan regularly helps it last longer, keeps it quiet, and makes sure it’s doing its job properly. It also improves indoor air quality — especially important in homes where windows stay shut most of the year.

2) Signs your fan needs a service

You don’t always need a professional to tell you when your fan is due a service. There are a few simple signs you can look out for:

• The fan is noisier than usual.
• You notice more condensation on mirrors or windows.
• It’s taking longer for steam to clear after a shower or when cooking.
• The grille or cover looks dusty or greasy.
• You can smell damp or stale air around the room.
• You hear rattling or vibration coming from the fan or motor. 

If you’ve noticed any of these, it’s a good idea to book a service before the issue turns into a bigger problem.

3) Recommended service intervals

How often you should service your fan depends on the type of system you’ve got and how often it’s used. Here’s a simple guide:

• Standard extractor fans (bathroom or kitchen): Every 6–12 months, depending on dirt build-up and moisture levels.
• PIV systems: Every 5 years, with periodic filter checks in between.
• MEV systems: Around every 12–18 months, or sooner if you notice airflow issues.
• MVHR systems: Annually, with filters cleaned or replaced every 12 months.

As a rule of thumb, I always tell customers — if it looks dirty or isn’t performing as it should, get it checked. Keeping on top of small maintenance jobs prevents costly breakdowns later.

4) What happens during a service

When I carry out a fan service, I make sure the system is running efficiently, quietly and safely. Depending on the system, that can include:

• Cleaning filters and grilles.
• Checking ducting for blockages or condensation.
• Making sure airflow is working as it should.
• Testing heaters or sensors (if fitted).
• Advising on filter changes or replacement parts if needed.

Every service is slightly different, but the goal is always the same — to keep your ventilation system running smoothly and your home’s air fresh and healthy.
