The Waterbury, Connecticut company holds 5 stars from 126 ratings on Google, 5.0 from 11 ratings on both Angi and HomeAdvisor, and an A+ from BBB, and says it has been in business 14 years. The state registry lists Connecticut hvac licence HTG.0409691-S1 as active, held by Eliezer G Chernin. An August 2025 restaurant customer said Eli replaced an entire walk-in cooler unit within 3 days and came by every day to put gas into the old one so the food would not be lost. An August 2025 general manager said Eli and his son repaired a walk-in cooler storing $100K worth of product the same day. A December 2024 restaurant customer said other repair guys called for a new compressor, and Chernin repaired the walk-in refrigerator without one. A September 2023 customer said the company was one of the only ones in the area certified to work with R290 and came out three times to replace a youth football program's commercial refrigerator compressor. On the residential side, a September 2025 homeowner had two units installed, one in the basement and one in the attic, in a single day. A December 2024 customer with a sparking gas boiler said Eli fixed the four problems a simple repair turned up that same day, at a reasonable price. A May 2026 customer said Eli and Joseph came out the same day for a spring a/c tune up. A July 2026 5-star Google review said the price was considerably higher than expected, because of the cost of freon. **Strengths:** - Walk-in cooler repair — 2024–2025 restaurant customers had coolers repaired or replaced - Same-day service — a 2025 manager's $100K cooler was repaired that day - Two-unit installs — a 2025 homeowner had both done in a single day **Concerns:** - Freon cost — a 2026 customer found the price considerably higher than expected ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - 5 stars from 126 ratings on Google _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=Chernin%20HVAC%20%26%20Refrigeration%20L.L.C.&query_place_id=ChIJUTlhMNHB54kR-o1UVpJVSks) — “Google: 5★ from 126 ratings” - 5.0 stars from 11 ratings on Angi and on HomeAdvisor _(confidence: high)_ - [Angi](https://www.angi.com/companylist/us/ct/waterbury/chernin-hvac-refrigeration-llc-reviews-1.htm) — “Angi: 5.0★ from 11 ratings” - [HomeAdvisor](https://www.homeadvisor.com/rated.AnaffordableHVACservice.125378553.html) — “HomeAdvisor: 5.0★ from 11 ratings” - Connecticut hvac licence HTG.0409691-S1, active, held by Eliezer G Chernin _(confidence: high)_ - [State License Registry](https://www.elicense.ct.gov/Lookup/LicenseLookup.aspx) — “CT hvac license HTG.0409691-S1 registry-verified active — registry holder of record: ELIEZER G CHERNIN” - Customers describe walk-in cooler and commercial refrigerator repairs and replacements _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2tKRVJqY3haMnR5ZDBrM1luSk1WR3BTWlhKM1dsRRAB!2m1!1s0x0:0x4b4a559256548dfa!3m1!1s2@1:CAIQACodChtycF9oOkJERjcxZ2tyd0k3YnJMVGpSZXJ3WlE%7C%7C?hl=en-US) — “5★ Eli and his crew helped get my restaurant out of a jam.
