# JHC Service LLC **Trade:** HVAC / Heating & Cooling · **Address:** PO Box 388, Brewster, MA 02631 · **Phone:** (774) 275-7059 · **Website:** https://jhcservicellc.com · **Languages:** English **Rating: 3.7/5** (low confidence) — from 0 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 JHC Service LLC is a Brewster-based heating and cooling company serving Cape Cod. Its own site describes a family-owned and operated business that installs and services mini-split systems, boilers and oil tanks and offers 24-hour emergency service, with customers naming the owner as Jay or Jason. The company says the owner has worked in the industry since 2005 and that the business has served Cape Cod since 2013. The same page states that JHC Service was formerly Ivy's Heating & Cooling, so older references may appear under that earlier name. The third-party record is thin but strong. In June 2026 a Nextdoor neighbour wrote that they called Jason at JHC Service and that he came the same day and diagnosed a mini-split fault their previous installer had spent roughly ten billed hours failing to diagnose and never fixed; the neighbour said they were impressed and passed on his cell number. On credentials the company speaks for itself: it states it is a Certified Fujitsu Elite Contractor, a recognized Energy Kinetics/System 2000 dealer and installer, and a Certified Roth double-wall oil tank installer. Those are the company's own claims rather than registry-verified findings, so ask to see them. Worth asking about before booking: the customer record here rests on a single detailed account, so ask for references on work like yours, and ask which reviews sit under the former Ivy's Heating & Cooling name. The BuildZoom entries carrying the company name are generated directory listings, not customer accounts. **Strengths:** - Mini-split diagnosis — Nextdoor neighbour credits a same-day fault find - Owner on site — the neighbour dealt directly with the owner - Oil heat work — site lists boilers, tanks and burner service - Fujitsu Elite status — stated certification on the company's own site - Emergency service — 24-hour availability per its own site **Concerns:** - Thin third-party record — one Nextdoor account, from June 2026 - Recent rename — site says formerly Ivy's Heating & Cooling - Self-stated certifications — Fujitsu, Energy Kinetics and Roth claims are the company's own ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - The company describes itself as a Brewster-based heating and cooling business serving Cape Cod that installs and services mini-split systems, boilers and oil tanks and offers 24-hour emergency service. _(confidence: medium)_ - [Official Website](https://jhcservicellc.com) — “A Brewster-based heating and cooling company serving Cape Cod that installs and services mini-split systems, boilers and oil tanks and offer…” - Its site says the owner has been in the industry since 2005 and the company has served Cape Cod since 2013, and that JHC Service was formerly Ivy's Heating & Cooling. _(confidence: medium)_ - [Official Website](https://jhcservicellc.com) — “Company history (self-reported): The contact page says the owner has been working in the industry since 2005 and the company has been in bus…” - The site describes a family owned and operated company, with customer quotes naming the owner as Jay or Jason. _(confidence: medium)_ - [Official Website](https://jhcservicellc.com) — “Ownership (self-reported): Described on the site as a family owned and operated company; customer quotes name the owner as Jay/Jason.” - [Official Website](https://jhcservicellc.com) — “Stated ownership (self-reported): Family-owned” - A Nextdoor neighbour wrote in June 2026 that Jason at JHC Service came out the same day and diagnosed a mini-split fault a previous installer had billed around ten hours to chase and never fixed. _(confidence: medium)_ - [Nextdoor](https://nextdoor.com/p/K5T22LnmdsRj) — “Nextdoor (Centerville, MA) — Cal Jason at JHC Service.
