Energy Efficiency


Your house may be costing you more money than it should due to inefficient energy use. Commonly, energy you pay for in the form of heat or air conditioning escapes through leaking windows and doors, insufficient attic insulation and leaking ducts. The first step to making your home more energy efficient is getting a home energy audit, where certified technicians using sophisticated equipment check your home for common sources of energy loss. They will prepare a detailed report outlining areas that could be improved and how much the work will cost. The best part is this service is completely free. It’s a great way to save on your utility bills and reduce your carbon footprint.

The best way to save money on utility bills at home is to get an energy audit by a BPI accredited professional. You can start by visiting Long Island Green Homes, a non-profit collaborative established to assist homeowners in making their homes more energy efficient.

  • Give your fridge a check-up: defrost, check seals, clean coils

  • At night, use air conditioners in bedrooms only (or use fans)
  • Close window shades on hot and sunny days
  • Improve airflow by making sure that heating return vents are clear of furniture and rugs
  • Replace your screens with storm windows in the fall to provide an extra barrier to the cold air.

  • Seal and insulate your heating ducts to improve the efficiency of your heating system by up to 20 percent
  • Replace conventional bulbs with ENERGY STAR qualified CFLs or LEDs.
  • Use task lights, dim room lights, turn outdoor lights off when not needed
  • Do laundry and dishes at night or in the morning, skip the dryer cycle. Hang your clothes outside when it's warm and experience that fresh-air scent!
