Does this replacement cooling system quote look high for Newcastle?
Asked by Leo Bennettin Newcastle, England· 3/20/2026· 1013 views
I'm in Newcastle, England and dealing with a 17-year-old replacement cooling system in our single-family home. Over the last three days, it has been coming in with very different tonnage and pricing and we're now noticing the upstairs stays noticeably worse than the main floor.
One contractor quoted GBP 445 for repair, while another jumped straight to a GBP 16,954 replacement because of the age. The weather here has been dealing us damp shoulder-season weather, 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 load calculation, duct condition, insulation assumptions, and line-set reuse.

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

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. For a replacement cooling system that is coming in with very different tonnage and pricing, the first things I would ask for are load calculation, duct condition, insulation assumptions, and line-set reuse. 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 Newcastle, England, pricing can move around, but the diagnostic process should still be clear.

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

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.

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

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

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 replacement cooling system in Newcastle.
