I have a sentinel kinetic V fitted in my loft, the system is 10 years old. This month it has started purging at around 8.30pm and this goes on for around 5 hours. It is extremely loud and can be heard on the ground floor. I have previously read about changing the settings, but I have noticed that the screen on the front of the unit is blank. It lights up when buttons are pressed, but there is no visible text. Does anyone have any ideas as to how I can sort this? We have resorted to turning off the unit at night now due to how loud it is. Thanks in advance!

Thanks for the replies, I don't believe there is a distribution box, everything is run off the ducting coming from the unit. The Y connector is feeds off the first runs going to different rooms. It looks horrendous in comparison to other setups i've seen on here. If I get no where with the builders I think I may have a go at a refit myself...

Thanks for the tips, the ducting used has the concertina effect on the inside. The guy rebalanced the air-flow but it made little difference. I clean the filters every 6 months, but I haven't checked the inlet and outlet for blockages though.

Hi Everyone, We moved in to our house in 2011. The property is a 3 bed new build with a Vent Axia sentinel kinetic V unit installed in the loft. Our house has always been extremely hot in the summer, but I always put it down to good insulation. I appreciate these units are not 'aircon' but it always feels very stuffy with no airflow. Early last month I was talking to a neighbour about how hot the houses are, and he brought up the MVHR unit. He mentioned that his had been getting poor airflow and he had someone out to look at it. He said this improved things with the heat, so I decided to follow his course of action and had a company come out and 'service' it. The results from the service were pretty shocking. The guy measured out house and said that our unit should be performing at an input and output of 35 litres of air per second. From his device he stated it was performing at 12... Even on the boost function he could only get it up to 17, which is still over 50% less than what it should be. The guy said that it had been installed poorly, with flexi ducting being used rather than rigid ducting. 4 inch flexi ducting had been fitted to the larger ducting to supply the individual rooms. He said that ultimately it would need a refit if I wanted it to improve at a cost of up to a few thousand pounds.. I immediately contacted NHBC to see if the unit was covered under the warranty, but they advised it isn't. I have also contacted the builders (Hillreed/now Persimmon) to see if they can help at all. My question is that based on the above, and if I don't get anywhere with Hillreed, how hard would it be to do myself? From looking at it, I think I could quite easily replace the ducting in the loft and also ducting the supplies the first floor rooms. Would this make a significant difference? I'm guessing ground floor rooms would involve taking up floor boards on the first floor? I can add some pics to show you how it looks at the moment if needs be. Thanks in advance, Tom
