We bought a new house this year and it had oil heat. We decided to try out the company that inspected the heater and that was a horrible mistake. The earliest appointment was a week out, so we had not oil in our tank that entire time. They lost our records twice, they hung up on my 6month pregnant girlfriend, and when we called back the next day, after it had snowed to confirm delivery, they said they would make it to our house in the next few days when weather permitted. They're in the business of providing heat during adverse weather! They even didn't bother to call us to let us know we didn't need to stay home from work.
