# Retrofit & Fan Array HVAC Systems

**Trade:** HVAC / Heating & Cooling · **Address:** 24 Gold St, Boston, MA 02127, USA · **Phone:** (617) 778-7126 · **Website:** https://baikalmechanical.com/ · **Languages:** English

**Rating: 3.2/5** (low confidence) — from 1 reviews across 3 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low.

## The honest read

Retrofit & Fan Array HVAC Systems is a Boston HVAC contractor with a single review on record. A 2024 review described a retrofit HVAC job on a fan array system that the customer said exceeded expectations.

With only one written review and no other independent verification available, there isn't enough here to characterize this company's typical work — ask for references from a completed job before booking.

**Strengths:**
- Positive retrofit job — exceeded expectations in a 2024 review
