Frequently Asked Questions — Troy

  • What is the most energy-efficient heating system for a home in Troy, MI?

    The most energy-efficient heating option for a Troy home depends on the home's age, insulation, existing ductwork, and whether it has access to natural gas. For gas-connected homes with existing ductwork, a high-efficiency gas furnace rated at 96–98% AFUE is typically the most cost-effective choice given Michigan's cold winters and relatively low natural gas prices. For homes looking for an all-electric option or a combined heating and cooling solution, a cold-climate heat pump or dual-fuel heat pump system can deliver excellent efficiency. Ductless mini splits are highly efficient for zoned applications or spaces without existing ductwork.
