How do I know my MVHR system works?
It’s a commonly asked question. The electrician has done his job if the light comes on. The plumber has done his if the water flows. However how do you know if your ventilation contractor has completed his job correctly? You can’t see air like you can light or water. In a bid to answer this question we suggest turning off the MVHR unit temporarily. Assuming the house is built to a relatively air tight level air quality should deteriorate quickly and air quality will suffer. You will find yourself wanting to turn it back on before too long. This simple experiment should demonstrate the effectiveness of your MVHR system.
