1. When you call the service company, you should always ask for the name of the individual who will be coming to your home to service your oil burner and for a cost estimate. Typically, there is a charge for a service call plus a fee for the parts needed. 2. You should always perform a license search to confirm that the person holds a valid oil burner certificate of competency. To do this, please follow these steps:

  1. Go to the Department of Public Safety website at www.mass.gov/dps
  2. On the right hand side under "Online Services", click on "License Search"
  3. Click on "DPS License Lookup"
  4. Make sure the search term is set to "Name" and enter the persons name into the search term space. A person holding a valid oil burner certificate of competency will have a "BU" indication under license type.

2. When the technician arrives, ask for proper identification.

3. A good technician will always ask questions of the home owner to assist in narrowing down the problem area. Typical questions include the following:

a. Has this happened before or is this the first time?

b. How was the unit running before it broke?

c. Was the unit making any odd noises or emitting unusual odors?

Has there been a recent power outage?

Have there been any recent changes to your heating system or its operation?

Have you hit any reset buttons or shut anything off?

Have you done on your own to attempt to resolve the problem?

4. If you agreed to the quote you should not be charged with an assistant without prior notice. If the labor necessary requires more than one person, you should be informed of this and have the ability to agree or disagree with the new quote. You should always stay with the technician while he is performing the labor to watch and ask questions.

5. The technician should check the position of switches and valves as well as the furnace for a buildup of oil inside the furnace before immediately hitting the reset button.

Finally, you should always feel free to ask the technician what the cause of the problem was; how he came to that conclusion; and what was done to correct the problem.
