Why can I hear noises from the DVS system Air
Handling Unit during the day and / or night?
It is possible that in the dead of night you may
be able to hear a very faint ‘hum’ from your DVS
system from certain rooms in your house. It is
also possible that you may hear it operating
during the day when the system is in boost
or bypass mode. If the DVS system is making
‘clunking’ or ‘clicking’ noises or is very noisy
it may indicate that an Air Handling Unit is
damaged or worn. Please contact us on 0800
DVS DVS (0800 387 387).
Why do I seem to get cooking and other smells
coming back into the house?
Venting extract fans to the outside is good
practice and the presence of smells is not due to
the operation of the DVS reclaim. If extract fans
or rangehoods are vented into the roof cavity,
please arrange a tradesperson to direct these
outside.
