Duct Cleaning
Anyone dealt with a duct system pushing weak airflow to the upstairs rooms in Glasgow?
Asked by Benjamin Diazin Glasgow, Scotland· 4/10/2026· 1671 views
I'm in Glasgow, Scotland and dealing with a 15-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 1,725 for repair, while another jumped straight to a GBP 16,542 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.

Before signing anything, I would ask the technician to show the readings and explain which number actually supports the recommendation. 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.

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.

From a contractor side, I would not approve a major repair or replacement without test results that line up with the symptoms.

The price range alone does not tell you enough. Ask what was tested, what failed, and which assumptions are built into the quote.

We used the directory reviews to filter out firms that were vague about what they had actually tested. That saved us a lot of time. 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.

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.

I would compare how clearly each contractor explains the diagnosis, not just the price. The clearer company ended up being the better hire for us.

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.
