MacFarlane Dunn Oil Company

MacFarlane Dunn Oil Company has kept homes warm across Maynard and surrounding Middlesex County for decades, earning a 3.5-star rating from 13 verified customer reviews. Operating from their Maynard headquarters, the company delivers heating oil and services equipment throughout Stow, Acton, and Concord. Their physical location and phone line handle customer inquiries Monday through Friday, 8 AM to 4 PM.

Several long-term customers specifically mention furnace repair capabilities beyond simple fuel delivery. Reviewers describe experiences with motor bearing replacements, same-day emergency calls during freezing weather, and equipment replacements handled with what one customer called "heartfelt admiration" during a difficult personal situation. The company has installed new furnaces and oil tanks for properties spanning multiple generations.

Customer experiences reveal a mixed track record. While multiple reviewers praise responsive same-day service and knowledgeable technicians who arrive within an hour of calling, others cite pricing concerns and delivery timeline frustrations. One reviewer noted a billing discrepancy involving tank volume charges that took nearly two weeks to resolve. The company appears to have undergone ownership transitions, with one customer reporting service from an affiliated company after placing an order.
