Langlois Plumbing, Heating & AC LLC says it has been in business for 32 years. Its website lists heat pump installation, central heat pump installation and ductless mini-split installation, and the service area it states covers Jericho, Burlington, Essex, South Burlington, Colchester, Winooski, Williston, Milton and Richmond. It holds a 4.7-star Google rating from 32 ratings and an A+ grade from the Better Business Bureau. A 2023 customer said Jaime Langlois came after one call when their NTI boiler burned out, then obtained the new equipment and finished the installation and testing in less than 10 days. That 2023 customer added that his price was considerably less than the two other quotes. A 2025 customer said Jamie and his crew installed two mini splits and a heat pump water heater in their home, with the cleanup done neatly. A 2025 customer said Jaime climbed down into the crawlspace under their house to trace a sewage smell, figured out the tub drain had no p-trap and fixed the problem right away. A 2024 customer said Jamie came right over and hooked up a new refrigerator after a big box store installation team shut off their water and refused to connect it. In a 2022 review, a customer said Jamie installed a new on-demand water heater to replace a 25-year-old tank and was on time and prepared. A 2022 customer wrote that after a new boiler unit was hooked up, VSG came out 3 times because the boiler would not stay on and was throwing codes. That 2022 customer said that when contacted he either responded with attitude or did not respond.
The best plumbing company in vt. U won't regret having this company do your work. Extremely clean and professional.
Jamie and his crew installed 2 mini splits and a heat pump water heater in our home. Our experience with them was great. Everything from communication and work to follow through and cleanup was done very neatly and professionally and i would highly recommend Langlois plumbing for any plumbing job.
The entire appointment went smoothly. He explained what went wrong and how to prevent a failure of that type of spigot.
We had a weird sewage smell that kept creeping into our bathroom. Jaime didn't hesitate to climb down into the nasty crawlspace under our house to investigate. He figured out our tub drain didn't have a p-trap. He fixed the problem right away. The whole visit was quick and easy and the problem remains solved. Great work!
We used Jamie for the plumbing on a major renovation to our house. When our hot water heater stopped working three years later, I called Jamie. He came to our house that day and was able to diagnose the problem right away. He contacted the manufacturer and confirmed that it was a defective control panel. I really appreciate his knowledge and personal service. He is prompt and responsive and I would happily work with him again.
