My previous fuel oil company had me wait two days for a service call when I had no heat. I called OSI to see when they could come, and they came that day. They came two hours later to check over my unit, fix the issue and sign me up. Service like this can’t be measured!

My entire family has been using OSI for over 25 years. They are the best and most reliable in the business. Like clockwork, before every major snowstorm, their trucks are out making sure customers are filled for heating. They are trustworthy and accessible, and service techs are knowledgeable. Don’t waste your time or money with anyone else.
