Duggan Oil Company delivers heating oil and propane out of Holbrook, and its two Google reviews on file both single out the same thing: speed. In a 2025 review, a customer of more than 30 years praised speedy, professional service from the technicians and office staff; in a 2023 review, another customer called the oil service excellent and always prompt. The company says it's family owned and run, with more than 40 years in the fuel-oil business. Alongside automatic delivery, it offers oil burner service, air conditioning service, and heating system installations, with free estimates on new installs. On Google, it holds a 4.8-star average from 6 ratings. Its BBB profile carries an A+ letter grade, though the business is not BBB-accredited. For Holbrook and the surrounding South Shore, this is a family-run delivery operation that's kept a clean, if thin, public reputation over decades in the same town.
