Annual Tune-Ups/Our Service Department

  • A properly tuned heating system can save you up to 10% in annual fuel usage.
  • The minimal cost of a tune-up is recouped by the efficiency gained in your heating system.
  • A regular tune-up aids in the longevity of your boiler or furnace.
  • Just like getting your car serviced, preventive maintenance helps extend the life of your equipment.
  • Our annual efficiency tune-up can help prevent a system breakdown that could result in a "No Heat" emergency service call.

If you have not had your annual tune-up please call our office today!

The TankSure® Program

Our TankSure® Program is a standard component of our Annual Tune-Up and Total Comfort Plan. This valuable program enables us to evaluate the safety and integrity of your oil tank. This is important for you and your investment in your home. At the time of your annual service our trained technicians will use ultrasonic testing technology to evaluate the thickness of your tank.

Heating oil tanks typically corrode from the inside out so your tank may look perfectly fine from the outside but could be wearing excessively thin. The annual ultrasonic testing process is designed to help replace your tank before it leaks. Qualifying customers will receive $1,000 toward a new tank when one is needed. In addition, you may be eligible for discounts on your homeowners’ insurance policy. Call to schedule your annual tune-up today!
