Ductless Mini-Split Installation
Fast, careful help for Cambridge homeowners considering a ductless mini-split.
A lot of Cambridge’s housing is older Victorians, triple-decker conversions, and condos in buildings that heat with boilers and radiators — systems that were never built with the ductwork central air needs. Where ductwork does exist in Cambridge homes built before 1980, it’s frequently undersized, leaking, or uninsulated, which is part of why retrofitting central air into an older Cambridge property tends to run more expensive than starting from a ductless system in the first place.
A mini-split sidesteps the problem entirely: no duct runs, no chasing trunk lines through century-old floor plans and tight utility spaces.
Real installation constraints — wall thickness, where a line set can run, panel capacity in an older electrical system.
A site assessment before any quote.
Yes — it’s one of the most common reasons Cambridge homeowners choose ductless over central air. No ductwork retrofit required.
Not for a mini-split. It runs independently of your existing heating system; a small line set through an exterior wall is all that’s needed per zone.
