When the temperature drops, that first heating bill can be a real shock. I get it—I’ve been there, staring at the number and wondering where all that money went. The good news is you don’t need to spend a dime on gadgets, space heaters, or fancy smart thermostats to start saving. In fact, most of the biggest savings come from changing a few habits and doing some basic maintenance you can handle this afternoon.

Start With Your Ceiling Fan (Yes, Really)
In most cases, Most people forget their ceiling fans exist once winter rolls around. But that little switch on the side is one of the easiest free fixes. Your fan should run clockwise at a low speed during the colder months, honestly.
In practice, Warm air naturally rises and gets trapped near the ceiling, leaving you cold on the couch. Running the fan clockwise at a low speed pushes that warm air back down the walls and into the living space without creating a wind-chill effect. It’s a subtle difference, but it can make a room feel a couple of degrees warmer without touching the thermostat.
Just make sure you flip the switch. If you stand under the fan and feel a breeze, it’s spinning the wrong way. When it’s running clockwise, you shouldn’t feel any direct airflow—just the air gently being pushed outward and down.
Give Your Thermostat a Schedule
I’m not going to tell you to freeze. But I will tell you that your house doesn’t need to be 72 degrees at 2 PM on a Tuesday when everyone is at work or school. The easiest money you’ll ever save is turning the heat down when you’re asleep or away, believe it or not.
Here’s the rule of thumb I use: 68°F when I’m awake and home, and about 60-62°F when I’m sleeping or out of the house. That’s a drop of 6-8 degrees for 8 hours a day. According to the U.S. Department of Energy, you can save about 1% on your heating bill for every degree you lower the thermostat for an 8-hour period. That’s roughly 10% a year if you do this consistently.
If you have a programmable thermostat, set it and forget it. If you have an old manual one, just make it part of your routine. Before you leave for work, turn it down. Before you get into bed, turn it down. It takes five seconds.
Unblock Your Radiators and Vents
This is the one that gets me. People spend money on new windows and insulation, but they’ve got a couch sitting directly on top of a floor vent. It doesn’t matter how efficient your furnace is if the heat can’t get into the room, believe it or not.
Walk around your house right now and check every single vent and radiator. Is there a rug on top of a floor register? Move it. Is a bookshelf pushed up against a baseboard heater? Slide it out a few inches. Are long curtains covering a radiator? Tuck them up on the windowsill or tie them back.
The goal is to create a clear path for the air to circulate. I also recommend checking that the dampers on your floor vents are open in the rooms you use most. If you have a guest room you never go into, close the vent and shut the door. Why pay to heat an empty room? Just make sure you don’t close off more than 20% of your home’s vents—that can cause pressure issues with your HVAC system.
Let the Sun Work for Free
The sun is the original solar heater, and it’s completely free. On sunny days, even in the dead of winter, the sun can add a surprising amount of heat to a room, in practice.
Open the curtains and blinds on all south-facing windows when the sun is shining. This lets the solar radiation in to warm up your floors, furniture, and walls. Those objects then release that heat slowly over the evening.
But here’s the flip side: as soon as the sun goes down, close them. A window is one of the weakest points in your home’s thermal envelope. Even a good double-pane window is much colder than a wall. By closing the curtains at dusk, you add a layer of insulation between the cold glass and your living space. If you have thick or thermal curtains, even better. This costs nothing and can easily make a room feel 2-3 degrees warmer at night.
Find and Plug the Drafts
You don’t need a professional energy audit to find the big leaks. You just need to use your hand. On a windy day, run your hand along the edges of your windows and exterior doors. You’ll feel the cold air rushing in, believe it or not.
The fix is usually free. That old towel you were about to throw away? Roll it up and stuff it at the bottom of the front door. That’s a draft stopper that costs you nothing. For window sashes, you can use a piece of old bubble wrap or even a rolled-up sock to jam into the gap.
Look for the usual suspects: the mail slot, the doggy door, the gap under the baseboards, and the opening where pipes come through the wall under the sink. For those small gaps, a little wad of newspaper or a strip of cloth can work wonders in a pinch. Old t-shirts and duct tape are commonly cited solutions, used more times than many care to admit. It looks a little rough, but it keeps the cold air out, and that’s what matters.
Zone Heat the Rooms You Actually Use
Instead of heating the whole house to the same temperature, think about where you actually spend your time. For me, that’s the living room in the evening and my bedroom at night, in practice.
Close the doors to rooms you aren’t using. This keeps the warm air contained in the rooms you are in. If you have a forced-air system, you can also close the vents in those unused rooms (just remember to keep at least 80% open as I mentioned earlier).
This strategy allows you to keep the thermostat a degree or two lower because the smaller space will feel warmer. You’re concentrating the heat rather than dispersing it. It’s a simple concept, but it works. My living room feels plenty cozy at 68°F when I’m in there with the door shut, even though the hallway is a few degrees cooler.
Wear Layers and Use What You Have
I know this sounds like common sense, but you’d be surprised how many people wear a t-shirt indoors in January and then complain about the heating bill. Before you bump the thermostat, bump up your clothing, in practice.
Put on a pair of wool socks. Throw on a hoodie or a fleece. If your feet are cold, you feel cold all over. I wear a pair of thick slippers around the house from November to March, and it genuinely allows me to keep the thermostat at 66°F instead of 68°F without feeling uncomfortable.
You also have a free heating device in your home: your oven. If you’re cooking dinner, leave the oven door open after you turn it off to let the residual heat escape into the kitchen. Same goes for running the dryer—the heat it generates warms up the laundry room. These aren't huge heat sources, but every little bit counts when you’re trying to avoid turning up the thermostat.
The Bottom Line
You don’t need to buy a single thing to cut your heating bill. The biggest savings come from simple behavior changes: turning the thermostat down when you’re asleep or away, keeping the heat in the rooms you use, and blocking the drafts that let it escape. Combined, these free habits can easily save you 10-20% on your winter utility costs. It takes a little effort and a change in mindset, but your bank account will thank you when spring rolls around, in practice.
Frequently Asked Questions
How much can I actually save by turning the thermostat down?
According to the U.S. Department of Energy, each degree you lower the thermostat for an eight-hour stretch saves roughly 1% on your heating bill. Doing that consistently works out to about 10% a year, and combining it with the other free habits in this article can push total winter savings to 10-20%.
Which way should my ceiling fan spin in winter?
It should run clockwise at a low speed. Warm air collects near the ceiling, and a clockwise spin pushes it back down along the walls without creating a breeze you can feel. If you stand underneath and notice airflow, the switch is set the wrong way.
Is it safe to close vents in rooms I don't use?
Yes, but only up to a point. Shutting the vent and door in an unused room keeps heat where you need it, but you should leave at least 80% of your home's vents open, since closing off more than 20% can create pressure problems for your HVAC system.
