Why bother with it now?

Heating oil is usually less expensive in the summer months so now is a great time to fill up the tanks and save some money. 
When the cold weather sets in and demand for heating oil rises, so do the prices.

When heating season starts, the companies who clean and service heating systems also get busy. 
If you wait until November to call, chances are you will be waiting for quite some time, or may even have to pay a fee for emergency service. 
If you call to schedule your service and cleaning for your heating system now, you will be ready for heating season without having to worry if your system is functional and safe.
