Better Insulation: Improved insulation not only keeps out excessive outside heat or cold, but also maintains even temperatures between and across rooms.  With proper insulation your heating and cooling system will use less energy.

Tight Construction: Tighter house construction can reduce energy use and improve the comfort of your home by eliminating unwanted drafts.  Drafts are air leaks that carry heat into or out of your house through cracks and holes.  Air sealing is an important way to reduce energy bills.

Energy Efficient Windows: High-performance windows can reduce your heating and cooling energy use by reducing heat loss in the winter and heat gain in the summer.

Tightly Sealed Ducts: In typical homes, duct leakage rates are as high as 20-30%.  Much of this leakage is into unoccupied space such as an attic or basement.  This means money is being spent unnecessarily to heat or cool your home.  To reduce leaks, duct systems should be sealed and checked by a professional.

Energy Efficient Heating and Cooling System: An efficient and properly sized heating and cooling system can result in significant savings on energy bills.  Most homes have heating and cooling systems that met the minimum efficiency standards at the time the home was built.  Replacing old systems with high efficiency systems can save as much as 20% by comparison.
