SolvedDuctless Mini-Split
What would you ask before approving ductless mini-split work in Montreal?
Asked by Avery Fosterin Montreal, Quebec· 4/16/2026· 227 views
I'm in Montreal, Quebec and dealing with a 10-year-old mini-split in our single-family home. Over the last month, it has been cooling one room well but leaving the others behind and we're now noticing the system sounds normal at startup but never quite settles into a steady cycle.
One contractor quoted C$1,225 for repair, while another jumped straight to a C$18,304 replacement because of the age. The weather here has been dealing us cold snaps followed by mild afternoons, 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 indoor head placement, line-set performance, fan speed, and zoning settings.

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 mini-split in Montreal. 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 mini-split that is cooling one room well but leaving the others behind, the first things I would ask for are indoor head placement, line-set performance, fan speed, and zoning 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 Montreal, Quebec, 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.

From a contractor side, I would not approve a major repair or replacement without test results that line up with the symptoms. For a mini-split that is cooling one room well but leaving the others behind, the first things I would ask for are indoor head placement, line-set performance, fan speed, and zoning settings.

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

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 mini-split in Montreal.
