Airflow over the plastic vent surrounds causes a static electrical charge which attracts dust to it, over time these look like dirty rings, simply remove with the vacuum cleaner or a clean dry brush. Do not use a wet cloth or cleaning fluids. The dust is from within the house, it does not come from the vents.

During the heat of the night in summer when the system is cooling your house, the fan will run at full, you may hear it but it is not obtrusive. This can be adjusted to suit. While in filtering mode you will not know it is running. A lot depends on the building materials, the amount of insulation and the acoustics in the ceiling.

No brand of system can claim 100% removal of condensation. Occasionally on very cold mornings you may see condensation on some windows but nothing like you used to and the system will quickly clear it whereas without, the condensation could stay all day. This is mother nature throwing stones.

The system has been designed with very complex algorithms, these constantly talk to the sensors and decide which fan speed works best under the climatic conditions. This is why sometimes the fan speed may run at full and other times very slow, if you had it running too high for long period it would be detrimental to your indoor climate. It is very smart, just leave it and let it look after you. If you believe the fan speed needs to be adjusted, please ask our technicians, we are more than happy to discuss this with you.

New homes can worse than older homes as they now built air tight with little opportunity to breathe. In our experience the extraction ventilation such as bathroom, kitchen and service areas are grossly underrated and do not effectively remove moisture. Before long your new house will feel damp and stuffy, you may even see mould appearing. Ventilation systems are a must in new homes and all homes in our opinion.

Double glazing is like insulation, it helps to keep warmth in, it does not help to keep a house dry. With the absent of condensation on double glazed windows, don’t be fooled, this disguises the fact that your home could still be damp. Double glazing is still important but it is for a different application.

With the BDVair system using the techno advanced EC motor and BDVairs exclusive Integrated management software, the average daily cost to run is $0.08c that is around $30 per year! This has been certified by electronic engineers.

The system uses outside air taken from the ceiling cavity, in general the ceiling cavity will be warmer than outside air. In very cold winter conditions, when this temperature gets too low, the BDVair integrated management software kicks in and slows the fan speed so you do not get too much colder air. In certain circumstances it will automatically switch itself off and the restarts when climate conditions improve. You do not know that this is happening, its all about doing what is right for your home.
