Daylight savings time ticks to its conclusion on Sunday, heralding months of shorter, colder days.

In that span, common issues like air leaks, old light bulbs and inefficient water heating can cost homeowners and businesses more than $1,000.

To winterize your home and cut your high energy bills, Puget Sound Energy suggests as follows:

• Replace old insulation: Filling, patching or caulking holes in floors and ceilings linked to unheated spaces can save 15 percent on heating costs. These updates may seem trivial but they can make or break your comfort during the winter. Learn about PSE’s weatherization rebates at www.pse.com/rebates/insulation.

• Update outdoor lighting with LEDs: Shorter days can make it difficult to see walking paths at home, making accidents more likely. Now is the time to check all outdoor lighting, as extreme temperatures can shorten the life of bulbs. Where you can, replace old bulbs with LEDs, which last up to 25 years longer, use at least 80 percent less energy and can save cut your energy bill.
