Firstly I have always known OSI to be great in delivery of oil , competitive prices and outstanding and friendly services. This past summer they came to the rescue when others would not for an air conditioning repair during a heatwave. during this past winter freeze Michael helped us get out of a frozen pipe situation that kept my business operating . Again OSI is a famiky run business that cares!!!!

Been a loyal customer for years and I do not believe we ever had an issue. However, what a horrible recent experience. I had called for a service for AC, after discussion they mentioned they needed a second cc on file because i did not have a cc for the AC, only heating. They even said "we will not send someone out until a cc is on file." I thought it was strange and I did not like the price or the policy, so i said something like "let me see in the am." I promptly then got another plumber to come by at a fraction of the cost. However, they apparently sent one of their plumbers immediately after (and without my permission or authorizations - and certainly without a CC on file) to do apparently redundant work. This is not my primary home so the tenant did not know it was not authorized. The

Long time customers for 2 generations. Always responsive for any servicing needs. Recently replaced 30+ year old boiler with a System 2000. OSI was able to rearrange their service schedule and two days later they were on site to replace our 3 zone system in a single day. I made the mistake of switching to a large company for a lower oil delivery price which also came along with poor servicing. The personalized and professional service of OSI cannot be beat.
