Preferred Energy Group

Violette Mechanical was originally started in 1991 in East Windsor, Connecticut. We then expanded into a full service oil delivery & service company in 1996 as Ellington Oil Company and into a full service propane delivery & service company in 2008 as Preferred Propane. All 3 companies are together with the office location at 64 Windsor Avenue, Vernon, Connecticut 06066. Our business hours are M-F 8 AM-5 PM and Saturday by appointment. We have 24 hours emergency service for our customers.  We offer automatic and will-call delivery of home heating oil & propane as well as complete heating and air conditioning sales and service. Our service technicians install propane tanks for residential, commercial and agricultural customers. They are trained and licensed to service all gas appliances. We also have experienced technicians for oil burner, gas burner, and air conditioning service. We are a Mitsubishi “Diamond Contractor” which adds 2 additional years of product warranty to our customers.  Preferred Energy Group has developed as a one call source for all heating, air conditioning, ventilation, and fuel service needs including any size propane tank installation with the option of renting or ownership for both residential and commercial customers.  We strive hard to make sure we keep up with the latest in technology while maintaining home town qualities and personal service.
