Does this duct system quote look high for Glasgow?
Asked by Aria Brooksin Glasgow, Scotland· 4/6/2026· 218 views
I'm in Glasgow, Scotland and dealing with a 16-year-old duct system in our older detached house. Over the past two weeks, it has been pushing weak airflow to the upstairs rooms and we're now noticing we are trying to decide this week and i do not want to sign off blindly.
One contractor quoted GBP 1,706 for repair, while another jumped straight to a GBP 9,051 replacement because of the age. The weather here has been dealing us cold overnight temperatures, 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 duct leakage, balancing, blower performance, and filter pressure drop.

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 duct system in Glasgow. Once we forced every quote into the same format, the decision got much easier because the weak recommendations stood out immediately.

From a contractor side, I would not approve a major repair or replacement without test results that line up with the symptoms. For a duct system that is pushing weak airflow to the upstairs rooms, the first things I would ask for are duct leakage, balancing, blower performance, and filter pressure drop. 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 Glasgow, Scotland, pricing can move around, but the diagnostic process should still be clear.

The recommendation should be tied to measurements, not just the age of the equipment. Age matters, but it is not a diagnosis on its own.

If this landed on my schedule, I would want to document the core readings first and then explain exactly why the repair does or does not make economic sense.

What helped us most was breaking the quote into labour, parts, warranty, and optional upgrades. The expensive bid looked very different once it was itemized. We had a related issue with our duct system in Glasgow. Once we forced every quote into the same format, the decision got much easier because the weak recommendations stood out immediately.

If you can, ask whether they checked airflow before recommending equipment. We nearly replaced a system when the bigger issue was elsewhere. We had a related issue with our duct system in Glasgow.
