Meet Jamie Langlois - Vermont Master Plumber and Certified HVAC Installer

Jamie Langlois grew up in Vermont and has been working in plumbing and HVAC since his apprenticeship years in the early 2000s. He obtained his Vermont Master Plumber license after completing the required apprenticeship hours and passing the state licensing examination – the highest level of plumbing credential issued in Vermont. He pursued HVAC certifications alongside the plumbing work because the two trades overlap in ways that matter to homeowners: boilers connect HVAC and plumbing, water heaters sit at both, and the person who knows both systems is more valuable than two separate contractors who don’t talk to each other.

The decision to focus on Mitsubishi and Daikin came from watching early cold-climate heat pump installations in Vermont – some by contractors who installed systems that weren’t rated for Vermont temperatures and left customers with underperforming systems. Jamie took the Mitsubishi Diamond Elite training program specifically to understand the systems well enough to install them correctly and to offer customers the extended warranty that certified installation unlocks.

Jamie Langlois is the owner and lead technician at Langlois Plumbing, Heating & AC LLC. Credentials include: Vermont Master Plumber license, Mitsubishi Diamond Elite installer certification, Daikin dealer certification, EPA 608 Universal refrigerant handling certification, and propane and natural gas certification. Jamie has been installing heating, cooling, and plumbing systems in Chittenden County, Vermont since 2010.

What Jamie Believes About This Work

The biggest mistake a homeowner can make isn’t choosing the wrong system – it’s hiring an uncertified contractor who installs a good system incorrectly. A Mitsubishi heat pump installed by a non-certified contractor doesn’t qualify for the 12-year warranty. A heat pump sized with a rule of thumb instead of a Manual J may be undersized for Vermont’s design temperatures. The credentials matter – not as trophies, but as verification that the work was done to a standard that protects the homeowner’s investment.

I also believe in being honest when something isn’t worth doing. If your existing boiler can run three more years, I’ll tell you that rather than recommending an immediate replacement. That approach costs me a job sometimes. It means customers call me back in three years when they do need the replacement, and they tell their neighbors. That’s a better business model than one that prioritizes the close over the honest recommendation.
