When energy prices rise, so do the number of ads for energy-saving products and services. Some of these ads are for gadgets and gimmicks that can’t deliver big energy savings. Look carefully at the claims and check for independent information about product performance. Don’t fall for unsolicited or high-pressure sales pitches from contractors or door-to-door salespeople. Make sure to ask friends and neighbors for their recommendations. Check out contractors with former customers and the Better Business Bureau. You can also check with the state or local consumer protection office and the state licensing agency (or home improvement commission). If you sign a contract in your home or somewhere other than a company’s permanent place of business, the FTC’s “Cooling-Off Rule” gives you three business days to cancel.
