If you can answer YES to any of these statements above, we have the answer for you at an extremely cost effective price.
How does it work?
lt ensures that old, contaminated, vapour laden air in your home is continuously diluted, displaced and replaced with good quality air. The result is improved indoor air quality and an environment in which condensation dampness cannot exist.
The old air exits through the thousands of air leakage points found in all homes. Indeed, positive input ventilation will even help to suppress unwanted infiltration (draughts).
The installation of a low energy Positive Input Ventilation unit will ensure the air in your home is completely replaced with better quality air around 20 times a day. This is the recommended rate to maintain good air quality.
How do I know if it will work?
We've installed a number of these systems. Not one customer has told us that it doesn't work well, infact the feedback has been incredibly positive. The only other consideration is that its strongly recommended that you have fans in your bathrooms and kitchens as this will help extract the excessive humidity that you have in these rooms (we can help with that as well).
Is it difficult and time consuming to install?
No! If you have a loft, we can install the system in less than half a day. If you don't have a loft, its a little bit more involved but can still be installed in most cases, in less than a day

We have standard charges of £580 plus VAT for a loft system and £640 plus VAT for a wall mounted system where there is no loft. This includes all labour & materials and is obviously subject to a site survey.
