Beware! Do not use Century Star Fuel Corp! Our boiler stopped working at 6 PM, and we called numerous times and did not hear anything back. Century Star didn't respond for over 12 hours. The temperature in our house was in the 40's. Finally, they sent a technician who reported that there was no oil in our tank. This was because the company failed to send a refill at the proper time, even though we had a contract for automatic delivery. Believe it or not, they said "Maybe" they would be able to fill our tank within 24 hours. Century Star can't be relied on in the winter! Don't use them!
