Indoor Air Quality
Repair or replace a 6-year-old whole-home air quality setup in Halifax?
Asked by Ruby Nguyenin Halifax, Nova Scotia· 4/14/2026· 233 views
I'm in Halifax, Nova Scotia and dealing with a 6-year-old whole-home air quality setup in our small commercial unit. Over the last three days, it has been leaving the house dusty and humid even after service and we're now noticing the upstairs stays noticeably worse than the main floor.
One contractor quoted C$1,691 for repair, while another jumped straight to a C$10,827 replacement because of the age. The weather here has been dealing us swing-season humidity, so I do not want to wait too long, but I also do not want to approve the wrong scope.
If you were comparing bids on this, what would you want checked first? I especially want to know how much weight you would give to return leaks, filtration sizing, humidity readings, and fan run settings.

We had something similar and the turning point was asking each company for the actual readings in writing instead of a verbal explanation. We had a related issue with our whole-home air quality setup in Halifax. Once we forced every quote into the same format, the decision got much easier because the weak recommendations stood out immediately.

The price range alone does not tell you enough. Ask what was tested, what failed, and which assumptions are built into the quote. For a whole-home air quality setup that is leaving the house dusty and humid even after service, the first things I would ask for are return leaks, filtration sizing, humidity readings, and fan run settings. If the contractor is recommending bigger work, ask them to explain which measurement supports that recommendation and whether they ruled out airflow or controls first. In Halifax, Nova Scotia, pricing can move around, but the diagnostic process should still be clear.
