Window Film Kit
Eliminate the chill that occurs right next to your large picture window without tethering yourself to a space heater? It's possible! A kit like this one (which covers five 3-foot by 5-foot windows) makes it easy: Just tape, cover with film, and heat with a hairdryer. The plastic shrinks to an airtight lining over the window, sparing you from heat loss and general draftiness. Plus, the Duck Brand estimates that sealing and insulating your whole home can save homeowners up to $190 in home energy costs. While window panes are just one location for heat loss, this under-$10 solution is a great place to start. Available on Amazon; $6.79.

For extra efficiency, the auto-off feature powers the pad down after 10 hours so that you don't waste any energy. Available on Amazon; $69.99.

Eve Door & Window Sensor
By mid-winter, a buttoned-up house gets stuffy and stale, so it makes sense to take advantage of fair weather days to crack a window and let in the fresh air. But if you're running the heat when you open your windows, you're letting energy—and money—escape. A door and window sensor, like this one from Eve, will notify you when your doors or windows have been left ajar and allow you to pause your heating system from an app on your phone until you have a chance to close them again and eliminate the draft. Available on Amazon; $39.95.

Unfortunately, it’s a common problem, but there’s a cheap and easy, inexpensive fix—Socket Sealers. Available on Amazon; $6.99 per 24-pack.
