It's a 12 year old modern 5 bedroom home. 4 Bedrooms and 2 bathrooms are on the top level accessible via ceiling space, so no, I don't really think it's a difficult installation.
I am going to query cleanaire on it.
Upstairs sounds straightforward then. Is the difficulty getting it downstairs?
I am unsure to be honest. It's a pretty standard 2 story house, there isn't much between the floors you could duct I'd imagine. There is $800 labour in my quote. The rest is parts.
