Boston Comfort Systems

Boston Comfort Systems, based in West Roxbury, works mostly same-day HVAC calls -- a frozen or leaking AC line, a furnace that won't light, a mini-split that needs service. In a 2026 review, one homeowner described searching all summer for an AC company with real availability, calling Boston Comfort Systems after competitors laughed off an urgent request, and getting the whole job done inside two weeks. The specifics that repeat across the record are speed and small, technical fixes done right: a capacitor replaced and the gas recharged on a lukewarm-blowing AC by 11am the same morning it was booked, in a 2025 review; a thermocouple swapped on a gas furnace, also in 2025; a frozen outdoor spigot and valve replaced in a tight water closet, in a 2026 review that names the technician, Vlad, directly. Scheduling draws specific praise too -- online same-day booking with a text notification and a photo of the technician before arrival, in a 2025 review. The record isn't clean, though. A 2025 review described being quoted roughly $10,000 for a full system replacement on an 8-year-old AC unit, only to have a family member with corporate HVAC experience question the diagnosis by phone. A 2024 review said a technician's diagnosis was so far off that a second company had to be called in for the same recurring issue, and a separate 2024 review said a repair made things worse with poor follow-up customer service. Two more reviews, from 2025 and 2024, described a repair estimate that was never delivered and a technician who struggled to communicate the problem clearly. Google shows 4.7 stars from 224 ratings, and the day-to-day record backs up fast turnarounds on straightforward jobs -- but the diagnosis complaints above are worth asking about directly, especially on a bigger-ticket repair-or-replace call.
