# RCL Plumbing, Heating, & Air Conditioning **Trade:** Plumbing · **Address:** 205 Onset Ave, Onset, MA 02558, USA · **Phone:** (774) 209-2085 · **Website:** https://www.rclplumbingheatingac.com/ · **Languages:** English **Rating: 4.1/5** (medium confidence) — from 75 reviews across 4 sources. 99% of sentiment-scored reviews read net-positive. Last 6 months: 1 reviews, 0 negative. ## The honest read RCL Plumbing, Heating & Air Conditioning works out of Onset, covering the Cape Cod and South Shore area for both plumbing and full HVAC systems — heating and cooling installs are clearly as central to the business as the plumbing in its name. Google shows 4.9 stars from 85 ratings, and the written record on file spans 2025 into 2026 with 75 reviews. One technician, Sergio, comes up again and again — one customer credits him with a third job at a newly bought old house, and another says he's fixed a leaking pipe and a boiler on separate visits. On the HVAC side, reviewers describe full system replacements handled start to finish: a 20-year-old central air unit replaced within two weeks of the first call, a 3.5-ton ductless split with five heads mapped and installed across two floors, an LP furnace and A/C combo installed in a Rhode Island condo, and a tankless water heater swap where the crew texted a photo of the installer ahead of time and walked the homeowner through the new setup afterward. Emergency calls get fast turnaround too — one review describes an A/C failure during a heat wave getting same-day triage and a full system quote by 6 a.m. the next morning. The one recurring theme worth flagging is price. One reviewer felt $600-plus for a two-hour drain-line clear with no parts replaced ran high, even while saying the technician himself was pleasant. Reviews otherwise consistently mention the crew explaining options and costs before starting, so getting a firm estimate up front on a straightforward diagnostic visit is worth doing. For anything from a stuck drain to a full heating and cooling system replacement, the reviews back a team that shows up, explains the work, and stands behind it. **Strengths:** - Repeat customer trust — same plumber returns for multiple jobs at one house - Full HVAC installs — heat pumps and ductless splits handled start to finish - Fast emergency response — same-day AC triage during a heat wave **Concerns:** - Diagnostic pricing — one review calls a $600+ drain-clear charge high ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Multiple reviews across 2025 credit the same plumber, Sergio, with repeat visits including pipe repairs and a boiler fix _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT20wMFZEUkZZbTFRZFVFeFVXdGxaRmxCVkUxSFpYYxAB!2m1!1s0x0:0x2ef22df4f43ddd13!3m1!1s2@1:CAIQACodChtycF9oOm00VDRFYm1QdUExUWtlZFlBVE1HZXc%7C%7C?hl=en) — “5★ Sergio, the plumber who came out to fix my boiler. did an excellent job.” - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2xFNGIwczFTalF6YzJoSFMwMWhabmxyVW5aS1NrRRAB!2m1!1s0x0:0x2ef22df4f43ddd13!3m1!1s2@1:CAIQACodChtycF9oOlE4b0s1SjQzc2hHS01hZnlrUnZKSkE%7C%7C?hl=en) — “5★ Sergio A. got here quicker than I expected and immediately got to work.
