"Diefenbach's Have Been Servicing Me for Many Years. Great Service! They Always Come Right Away When I Call. "
"We have lived in Otisco for 32 years and this is the only company I will use for my heating oil. When we first moved out here we were not familiar with the process and in the dead of winter during a storm we ran out of oil in the middle of the night. We had a 4 mo old. Ron senior drove his truck to my home at 6 Am and put enough oil in our tank to warm my house until the roads were cleared to get the oil truck up here. Trusting caring company. I highly recommend them "
