Included in the Security Plan is an Annual Burner Tune-up. This is scheduled by appointment and is a 23 point inspection and tune-up of your heating equipment. This could save you up to 10% on your heating costs by keeping your equipment in maximum operating efficiency.

Automatic Delivery
Using a Degree Day Monitoring System we can track your heating oil consumption based on the weather. We then automatically schedule oil deliveries when needed. We will charge your credit card upon delivery and save you 10 cents per gallon on our already low COD pricing.  

COD Delivery
COD delivery is for customers who prefer to monitor oil levels on their own. We ask that you call to schedule your delivery when your tank reads between ½ and ¼. Payment is due on the day of delivery.

24-Hour Full Service Contracts & Emergency Service
Preventative maintenance is extremely important to ensuring you stay warm and comfortable all winter long! We have experienced technicians on duty 24 hours a day, 7 days a week. Protect your heating system with our annual Security Plan, which includes a 23 point inspection and tune up of your heating equipment.

Tune Ups are available anytime during the year but we highly recommend scheduling your annual tune up during the summer so you can be sure your system will be running at peak efficiency during the heating season.
