MVHR - Noisy Fan!

Followers

November 27, 2025Nov 27

Hi All

I have a Vent Axia Sentinel MVHR, it is only 2 years old but has a very noisy fan! I have managed to get a replacement fan from Vent Axia (see pic) but as over a year old they wouldn't repair it.

The noise is now driving me mad so want to get this replaced ASAP

Please see attached picture my install in the loft, do all 4 solid ducting inlet/outlets need to be removed? Could it this repair be done just by taking the side off?

I am hoping its pretty obvious which fan it is when i take the covers off etc..

I am electrician by trade, how long would this repair hope to take if all goes well? Would it matter if the house doesnt run for MVHR for a day or 2 if I have to do it in evenings?

Any advice/information on this would be very helpful

Kind Regards
