HVAC and Plumbing Services in Williston, VT

Williston has transformed in the past fifteen years from a quiet Vermont town into one of Chittenden County’s most active residential and commercial corridors. The Taft Corners development zone has added thousands of new homes, many built to modern energy codes with forced-air systems where a heat pump replacement makes immediate sense. Williston Village, by contrast, has a historic housing core where we’ve done everything from replacing cast-iron steam radiator boilers to installing ductless heat pumps in 1850s-era farmhouses.

Williston, Vermont - one of the fastest-growing communities in the state - is served by Langlois Plumbing, Heating & AC LLC with heat pump installation, high-efficiency boiler replacement, and licensed master plumbing services. Williston's rapid residential development includes a high proportion of newer homes ideally suited to heat pump primary heating systems. We are 18 miles from Williston and schedule same-day service for most requests.
