Taking a whole-house approach to energy efficiency will help you get the most out of your monthly bill and keep your home at its peak comfort level. These free and low-cost improvements can reduce your energy consumption and your payments, especially in the cold winter months. 

Low-cost home improvements

Low-cost home improvements

  • Install high-performance showerheads and faucet aerators in all sinks. You can efficiently heat water and maintain water pressure.

  • Service natural gas appliance and equipment annually. NW Natural Preferred Contractors can do this for you.

  • Cover hot water pipes with insulation. Do the same with the first six feet of cold water pipes, too.

  • Maintain caulking and weather stripping. Fix when you see cracks, and use around windows and doors.

  • Fix dripping faucets. Any plumbing issues should be addressed immediately.

Keep furnace filters clean.

  • A dirty filter slows air flow, makes the system work harder and wastes energy.
  • Recommendation: Change your furnace filter at least four times during the fall/winter season.

Adjust vents.

  • Make your adjustments based on the season and room location.
  • For example, heat rises, so upstairs rooms need less of it.
  • Recommendation: Don't close more than one or two vents in an average-sized house. 
  • Restricting airflow can shorten the life of your furnace.

Limit use of ventilation fans.

  • Use kitchen, bath and other fans only as needed, especially in winter.
  • Recommendation: Never keep fans on for more than an hour. They can blow away a houseful of warm air.

Wash dishes and clothes with full loads only.

  • Recommendation: Scrape food residue off plates instead of using water to rinse.
  • Wash clothes with cold water.

Use draperies, awnings, blinds or shutters on all windows.

  • It slows the loss of heat through the glass.
  • Recommendation: In winter, keep window coverings open on sunny days and closed at night to insulate against cold outside temperatures.

Close dampers when not using your fireplace or woodstove.

  • Recommendation: Wait until the fire is completely out, which could take several hours.
