## The honest read

Dan Dunn Plumbing & Heating carries a 5-star Google average from 95 ratings. The company says it is family-owned and has provided plumbing and heating services in the New Hampshire Seacoast area since 2000. Its New Hampshire HVAC licence, MBE1600922, held by Dan Dunn Plumbing & Heating, LLC, is active on the state registry.

A recent customer who manages property said they ran into an underground broken pipe at a condo they manage, and the company was able to step in and get the problem solved. A recent customer said Braden helped them twice and helped them make smarter decisions about their plumbing needs. A general contractor wrote recently that Dan's team always shows up on time and cleans up after themselves.

A 2026 customer said a technician spent a full two hours on annual maintenance of their tankless water heater, including a complete flush and testing, and referenced the Navien service manual for their exact model. A 2025 customer said the company came out the day they called in winter and replaced their boiler within the next few days. A 2025 customer with a mobile home said the company told them the gas water heater only needed its sediment drained and a new expansion tank, for under $400, after another plumber had quoted $5000. A 2025 customer said a replacement hot water heater was approved by the town inspector, and when a manufacturer defect caused a minor leak, the company handled the replacement.

A 2023 customer described a burst pipe at a vacant storefront in a retail plaza their family owns: Dan was the first of the plumbers they contacted to respond, at 6:30 am, and capped the pipe, and the repair was done within 36 hours of the break. A 2023 customer said that after their wall-unit boiler broke, a crew of three led by Brayden did the entire combi boiler job the next morning, laying thick paper down on the floor to the utility room.

**Strengths:**
- Emergency pipe capping — a 2023 customer said Dan responded first and capped the pipe
- Next-morning boiler job — a 2023 customer said a crew of three finished it that day
- Tankless heater maintenance — a 2026 customer described a two-hour flush and testing
- Cleanup after work — a recent general contractor said the team cleans up after themselves
