Dave the Plumber LLC.

Heating-system troubleshooting and household plumbing both feature in customers’ accounts of Dave the Plumber LLC. The business describes itself as a family-owned, owner-operated Salem, New Hampshire contractor with 25 years in business, serving homes and businesses across New England. It emphasizes heat pumps and ductless mini-splits and says it is an authorized GREE Select Dealer. Google shows a 4.8-star average from 20 ratings. The detailed installation stories are dated. In a May 2025 review, a customer described a failing heating system and said Dave prioritized the replacement so the household would have heat and hot water during cold weather. The customer said he set up a temporary water heater and priced the installation below higher estimates. Another homeowner, writing in January 2025, described a combined boiler and water heater that struggled to meet demand in a 5,000-square-foot house. That customer said Dave stabilized the immediate heating problem, helped develop a longer-term solution and subsequently returned for annual service and other repairs. Ductless and heat-pump work also gets specific praise. A June 2023 reviewer described a ductless installation for the entire home and said Dave was on time and easy to contact during the process. In a November 2022 review, a Massachusetts homeowner described replacing central air with a heat-pump system, with explanations of each stage and respect for the customer’s night-shift schedule. The same reviewer later hired him to replace toilets and a bathroom sink and install shower grab bars. An April 2023 customer separately described toilet and vanity installation and new hardware in an existing bathtub. Repair accounts include an April 2023 review describing a same-day response to nine pipe breaks in a crawl space. A March 2026 reviewer praised neat plumbing work, communication and suggestions for the project. A May 2026 Reddit commenter recommends Dave the Plumber out of Salem after a positive experience. One July 2023 Google reviewer describes an unresolved garbage-disposal problem after paying $300. The customer says the plumber promised to return, missed the return date and did not respond for months, leaving them to hire another plumber. That complaint concerns both the unsuccessful repair and the promised follow-up.
