Kellogg Heating & Cooling

Kellogg Heating & Cooling runs HVAC calls out of Allston, covering Brighton, Brookline, Cambridge, Somerville, and the Back Bay, by its own account. Every one of its 40 Google ratings is five stars, and two independent directories that track the same business separately show a similarly perfect average — one counts 43 reviews, another 54. The last six months brought eleven reviews and zero complaints, and the same story keeps repeating: fast turnarounds on the calls that can't wait. A compressor got swapped in minutes during a 90-degree stretch, a failing thermostat was replaced with a modern model during a heating diagnosis, and an AC problem traced one day was fixed the next. A two-zone mini-split installed in March came in at the price quoted, with the crew finishing the whole job in a single day and leaving the rooms cleaner than they found them. One thing worth flagging before taking the full review count at face value: a handful of the older five-star reviews on the same Google listing name other companies outright — a commercial HVAC installer, a different heating outfit, even a plumber — which points to some cross-posted or misattributed reviews sitting alongside the real ones. None of that turns up in anything from the last six months, so it's a reason to weigh the recent handful more than the headline number of 40. For an Allston or Brighton household dealing with an aging mini-split, a dead compressor mid-heatwave, or a heating system overdue for a smart thermostat, this looks like a shop whose actual customers keep calling back for exactly that kind of job. Worth asking directly who's on the truck, given the mix-up in some of the older reviews.
