WESTFIELD, Mass (WWLP) - State Line Propane and Oil cut the ceremonial ribbon for their show room and service center in Westfield Friday. The family own and operated business has been serving customers in Connecticut and Massachusetts from their location in Granby, Connecticut since 1999, but now they have a location in western Massachusetts. Final weekend of The Big E’s record-breaking run "We want to have a presence in Massachusetts so people in the Massachusetts area can use us and use our services for propane, oil, HVAC and fireplaces at their houses" said State Line Propane and Oil owner, Brian Guarco. In the showroom, customers will be able to see the items before they make the purchase. The location has grills, boilers, hot air furnaces, fireplace inserts, and more. Guarco said his staff looks to meet and exceed customer expectations with their service.
