Our Story
The Tereshchuk family immigrated as Ukrainian refugees in 2001 searching for better career opportunities. The family had 16 members—two parents and fourteen children (not counting grandchildren), and came directly to Massachusetts where they’ve remained since.
Anatoliy Tereshchuk was an agriculture farmer, but graduated from Porter and Chester with an HVACR diploma. From there he did an apprenticeship and decided to open his own business.
Fedor, one of Anatoliy’s sons, had an opportunity to take over the business after some years. Fedor graduated from an HVAC program in 2008, and Delta HVACR has been serving the area for the last 15 years.
