If you can find someone that would be great. But I’ve 2 of those same units installed for clients, and they are designed to be easily serviced. So far as I recall, there’s good maintenance instructions in the installation instructions. Any competent installer should be able to help; doable as DIY.
It is the MVHR system that I’d like looked at by an expert - the airflows, duct condition, energy use…. @jeffcolley.bsky.social @wmaarch.bsky.social any idea who can service the Paul Novus?
One question: did you get the TFT controller installed originally? It’s a small digital control, wall mounted, brushed stainless surrounding a touch screen.
Yes.
Do you have filters installed at the registers in the kitchen, bathrooms and other extract locations?
