Getting optimal performance depends on more than just choosing the right equipment.

  • Consult with experts: Ask an energy advisor or contractor how an ENERGY STAR® certified natural gas furnace could transform your home.
  • Get a heat load calculation: Ask the builder to confirm that the heating contractor calculates the heat requirements to ensure your gas furnace is sized properly.
  • Ask about duct design: Have your builder show you a layout of where the equipment and ductwork will be installed. Confirm that the duct connections including vents and registers are going to be well-sealed.
  • Don’t forget about commissioning: Commissioning is a critical quality assurance step that should not be overlooked to verify and document that the engineered performance has been achieved.
  • Maintain your equipment: Similar to servicing a vehicle, preventive maintenance is a good investment to minimize future problems. Arrange for annual servicing. Clean and replace air filters regularly. Consult the owner’s manual for details.
