Harwich Port Heating & Cooling, LLC

Harwich Port Heating & Cooling is one of the larger home-services companies on the Cape — HVAC, plumbing, electrical and generators under one roof, working from Harwich Port across Cape Cod and into the South Shore. BBB records the business as started in 1978 with 80 employees, and its Massachusetts sheet metal licence, 720-SM-B, is verified active with the state registry in the company's own name. Google shows 4.8 stars from 796 ratings. Installation work draws the strongest accounts. A July 2026 reviewer described an A+ whole-house mini-split installation where their point person suggested the best locations and answered every question through the job; a July 2026 heat pump customer called the team exceptional from consultation to final installation; an August 2026 boiler installation was described as smooth, tidy and good-looking. Seasonal and emergency work is the other half. A December 2025 reviewer returning from travel to no heat on the coldest day of the year had two technicians there within two hours and the fault fixed in under thirty minutes. A January 2026 reviewer who called on a Saturday before a storm at 8 degrees had someone at the furnace that afternoon. A May 2026 reviewer opening a Chatham house for the season had a technician diagnosing the hot water inside an hour. A February 2026 reviewer needed a beach house winterized at short notice in deep snow and got it. The consistent weak point is reaching them, and it shows up even inside five-star reviews. A June 2026 reviewer happy with their AC, generator and maintenance still said getting call-backs has sometimes been difficult. A December 2025 reviewer called the answering service four times over two hours for emergency service — and then praised the technician who eventually came. A February 2026 caller at 6:30pm on a Saturday was told by the answering service that the 24-hour emergency line is for existing customers only, which they called false advertising. Three complaints go further. A July 2026 reviewer said they spent nearly $8,000 on new air conditioning that does not work, and that calls and texts go unanswered. A July 2026 reviewer said a technician left the outside circuit breaker off after a routine AC service, so they paid someone else to find out why the AC had stopped, and the company would not discuss the cost. A July 2026 long-standing customer lost their air conditioning after an extremely hot day, six weeks after the company had completed their annual maintenance. So: strong crews and strong installations, with a front office that struggles under load. Ask what the response commitment is in writing, confirm whether you count as an existing customer for the emergency line, and get any post-service fault looked at before the invoice is settled.
