My husband and I have worked with Ralph. Mann and their Office Manager Wendy for 46 years. Ralph Mann has always served us promptly and efficiently-several times wading through snow drifts to make sure we had enough oil
We love Wendy! Talking to her is like talking to a friend. She makes sure we understand what we need, when service will arrive and the name of the technician. True professionalism all around!

The day the snowstorm came our furnace stopped working at
6:00 p.m. I placed an emergency call to Ralph Mann and a technician immediately called me back. He told us what to do but unfortunately it didn't work. He couldn't come out due to the storm. So at 7:30 a.m. I received a call from Wendy who is a top notch employee at Ralph Mann that the technicians were on their way and they were here within 15 minutes. They figured out what was wrong and got the furnace up and running. I would suggest that anyone looking for a great oil company to call Ralph Mann. They have always had our backs. Nancy and Joe.
