Nobody opens the winter energy bill and says, “Wow, what a bargain.” If you want to lower your heating bill, you don’t need a new furnace or a second mortgage. You need a few small fixes and a little follow-through.
Here are ten that actually work. Most cost almost nothing. Several take less than ten minutes.
1. Turn the thermostat down a few degrees
This is the biggest lever you have. The U.S. Department of Energy suggests setting your thermostat around 68°F when you’re home and awake. It also says turning it back 7 to 10 degrees for about eight hours a day can save up to roughly 10 percent a year.
Do it while you sleep or while you’re at work. Your blankets are already free.
2. Install a programmable or smart thermostat
Nobody remembers to adjust the thermostat every single day. A programmable model does it for you. Set a schedule once and let it run.
3. Change your furnace filter
A clogged filter makes your system work harder to push air through. Check it monthly during heating season. Replace it when it looks gray and fuzzy, or follow the schedule on the package.
4. Seal the drafts
Air leaks are sneaky. Light a stick of incense and hold it near window frames, outside doors, and electrical outlets on exterior walls. If the smoke wiggles sideways, you’ve found a leak.
Fix the leaks with:
- Weatherstripping around doors and movable window parts
- Caulk around window frames and where pipes enter the house
- A door sweep on the bottom of exterior doors
- Foam gaskets behind outlet covers on exterior walls
A tube of caulk costs a few dollars. Your heat stays inside where it belongs.
5. Let the sun do some work
Open the curtains on south-facing windows during the day. Free solar heat is still free. Close them at dusk to hold the warmth in.
Heavier or thermal-lined curtains help a lot on cold nights. Cheap window insulation film kits work too, and they’re easy to put up.
6. Reverse your ceiling fans
Warm air rises and gets stuck near the ceiling. Most ceiling fans have a small switch on the motor housing. Set the fan to spin clockwise on low speed. That gently pushes warm air back down without creating a breeze.
7. Don’t heat rooms nobody uses
Close the vents and doors in guest rooms and storage areas. Just don’t shut off too many vents at once. Some systems don’t like it, and it can cause problems. When in doubt, check your manual or ask an HVAC pro.
8. Move the furniture
Is a couch sitting on top of a heat register? Is a curtain hanging over a baseboard heater? Move them. Blocked vents waste heat and make your system work harder.
9. Check the water heater
Most households can set the water heater to 120°F and be fine. Lower temperatures use less energy. Wrap an older tank in an insulating blanket if the manufacturer allows it.
10. Close the fireplace damper
If you have a fireplace you rarely use, the damper is a big open hole to the outdoors. Close it when you’re not burning a fire. If you do light one, open it fully first.
Don’t forget the layers
Okay, this one isn’t a repair. But a sweater, warm socks, and a throw blanket let you drop the thermostat without feeling it. It’s the cheapest upgrade on this list.
Where to start
If you only do three things, do these:
- Lower the thermostat at night and when you’re away.
- Replace the furnace filter.
- Seal the biggest drafts around doors and windows.
Those three alone can make a noticeable dent in your bill. Then work through the rest as time allows.
Ready for a deeper dive? Many utility companies offer free or low-cost home energy audits. Check your provider’s website. It’s a smart way to find the leaks you can’t see.
Stay warm, and keep that money in your wallet.
