Michigan utility customers may be eligible for a free furnace or boiler tune-up through a statewide energy efficiency program. Tune-ups ensure heating systems are running cleanly and efficiently, saving residents money and eliminating health and safety risks.

Blue Terra Energy is conducting the free tune-ups, normally priced at $100, for natural gas utility customers in the western Upper Peninsula. Residents must be Semco Energy Gas Company customers to qualify. Customers can call (906) 487-5342 to schedule.

The free furnace and boiler tune-ups are funded by revenue collected from a small surcharge Michigan utility customers currently pay on their monthly bills. In addition to a free tune-up, customers may also be eligible to receive a new programmable thermostat and/or new carbon monoxide detector, free of charge.
