How does a PIV system actually work?proach to social media?
PIV units push filtered fresh air into your home from the loft or wall unit. This gently forces out stale, damp air through natural leakage points and extractor fans, dramatically reducing condensation and mould.
Will a PIV unit make my house colder?
No! Modern PIV systems use pre-heaters to ensure the incoming air stays warm and comfortable, especially in winter.
Is a PIV system noisy?
Not at all. Installed correctly, most people hardly notice the unit running—it operates silently in the background.
How long does installation take?
Most PIV installations are completed in just half a day with minimal disruption to your home.
Does a PIV system help with allergies?
Yes—because it filters incoming air and reduces indoor moisture, it can significantly lower allergens like dust mites and mould spores.
Asthma Symptoms Dramatically Improved
My son’s asthma was getting worse every winter. After the PIV system went in, his breathing is so much better, and we haven’t seen any mould reappear. The team were brilliant—friendly, tidy, and really cared about getting it right.
No More Condensation, Our Home Feels Brand
We used to wake up to dripping windows and a constant musty smell. Since OVM installed our PIV unit, we haven’t had any condensation at all. It's completely changed the feel of the house—fresh, dry, and comfortable!
