We have relied on Dunn Oil / Maynard keeping us warm every fall and winter for years. Their service from providing Oil or emergency service is great!

We have used Dunn Oil for almost 20 years. Theyve always been quite responsive and accommodating.Today our behemoth of a furnace started making a funny noise.I called the company since its below freezing at the moment. Someone was there less than an hour later and replaced the bearings of the motor. Furnace is running again. Technician was super knowledgeable and very friendly. Truly great service!

Dunn Oil .. Your call back within minutes after we spoke today fixed my issue. It feels good knowing someone cares about their customers like you do.Thank you..

Ive been with Dunn Oil for all of my different properties throughout Stow, Maynard, Acton and Concord. Theyve done everything from new funaces, to new oil tanks and deliveries for me since the sixties. I trust them and my properties depend on them.

Ive been with Dunn oil for over 20 years now and they have always gone out of there way to help me.
