## The honest read

Lake Sunapee Plumbing & Heating's New Hampshire plumber license, number MBE0003543, held by Lake Sunapee Plumbing & Heating, LLC, is active on the state registry.

A Reddit commenter in r/newhampshire said they had to call the company out for 3 visits when it put in a new fuel tank.

A 2013 customer said the company researched a furnace issue with the manufacturer instead of replacing an entire panel, and fixed it quickly and more economically. That 2013 customer said the company also answered a middle-of-the-night call for a water heater that went bad, and had a new one installed within two hours. A 2012 customer said they had the company do boiler preventive maintenance and improve the controls, and that the work was explained to them. A 2016 customer said they got a free estimate, the project was completed in a little over a day, and the final cost was within the estimate.

A 2017 customer said a trap came loose twice and flooded their bathroom, that it took 3 trips to get it secure, and that the office threatened small claims court over an $88 bill for the third visit. A 2016 customer accused owner Randy Wiley of underbidding, overcharging and leaving work incomplete, and said he sued them. A 2014 customer said a contracted mini split system took several more weeks to get working after the install.

**Strengths:**
- Furnace repair — a 2013 customer said it was fixed more economically
- Night water heater call — a 2013 customer had a new one within two hours
- Estimate held — a 2016 customer said final cost was within the estimate

- A loose trap — a 2017 customer said it flooded their bathroom twice
- A lawsuit — a 2016 customer said the owner sued them
- Mini split install — a 2014 customer said it took weeks more to work
