FAQs To Our Office in Leominster, Massachusetts


What can I do to save energy?

1. Turn off the furnace or boiler as summer approaches.
2. Set the thermostat back 5 to 10 degrees at bedtime or when you are away from home for an extended time.
3. Adjust humidity levels. The recommended range is 40% – 60%. Higher relative humidity levels allow people to feel more comfortable at lower temperatures.
4. Caulk and weatherstrip around doors and windows, and/or add insulation to the attic, wall, and floors.
5. Consult with your oil dealer about the possibility of lower temperature settings on the boiler or furnace controls.
6. Consider installing a storage tank or a stand-alone hot water heater if your boiler heats your domestic hot water with a tankless coil.
7. Gradually reduce the temperature in your home during the winter months. You'll soon find the lowest level that is comfortable for you.

How can I tell if my burner has been tested?

Look for a 1/4" hole in the smoke pipe near the boiler or furnace. The unit has not been tested unless there is a hole to insert the combustion testing equipment probes into. This hole must be between the furnace and draft diverter or damper.
