Northpoint Mechanical, LLC describes itself on the BBB as providing plumbing, heating and cooling services. A 2022 customer said Dave, the owner, came to replace a broken oil fired water heater and started the work 3 days after giving the price. That customer asked him to inspect a 28-year-old hot air heating system while there; it was leaking, and so was the interior 275 gal oil tank, and the 2022 customer said the price to replace it all was much less than expected. A 2025 customer wrote that they responded within a day, quickly diagnosed problems, and helped with a water softener, filter, new fixtures, new propane lines and furnace cleaning, all reasonably priced. A 2022 customer said David did a boiler repair. A 2022 customer said David came out the same day to install a faucet. A 2024 customer said Dave solved their plumbing problem in less than 5 minutes and did not charge for the visit. A 2019 customer said David re-installed a mixing valve in their bathroom. A 2020 customer said they never heard from the company after the plumber came for a shower stall job, and wrote that the job seemed too small for its tilers. David M Lovlien, Sr holds New Hampshire hvac licence GFE0905420, which is active on the state registry. The company's own New Hampshire hvac licence, MBE1801079, is expired on the state registry.
