Billerica, once the village of Shawshin
Billerica grew from the Praying Indian village of Shawshin, settled by families from Cambridge and Charlestown by 1652, incorporating in 1655 on the same day as Chelmsford and Groton, named for Billericay, England. An HVAC project in Billerica should account for systems installed across distinct eras since the town's 1655 incorporation.
