9 Cost-Effective Ways to Keep Your House Warm This Winter

Warm Up Your Space: 9 Practical Ways to Keep Cozy Without Using More Heat

Our homes are more than just structures—they function as interconnected systems. Each component works to enhance safety and comfort. The roof protects against rain and snow, the plumbing delivers clean water and removes waste, and the heating system—whether it’s a furnace, boiler, or heat pump—keeps us warm during the chilly winter months. However, these systems aren’t always cost-effective or energy-efficient.

January and February are the coldest months of the year for most of the U.S. However, Lifehacker experts say November to March, heating expenses can range between $601 and $1,851, depending on your heating system. If your home often feels colder than desired, these costs may rise even further as you crank up the thermostat or rely on space heaters. To combat the cold and manage heating bills, try these affordable (or even free) weatherproofing tips to keep your home cozy throughout winter.

If you’re tired of battling the cold and high heating bills, consider these simple, inexpensive (or even free) steps to weatherproof your home and stay comfortable this winter.

1. Install Duct Booster Fans

If your HVAC system struggles to push enough air through certain registers, duct booster fans can help. These fans are installed into your HVAC registers to improve airflow, making your heating (and cooling) system more effective. They’re easy to install and can make a noticeable difference, especially in rooms where airflow feels weak.

2. Reverse Ceiling Fans

Ceiling fans aren’t just for summer. Set them to run clockwise during the winter to pull cool air up and push warm air down. This simple adjustment helps redistribute the heat in your home, making it feel cozier and reducing heating costs.

3. Block Chimney Drafts

Fireplaces are cozy, but they can also let cold air seep into your home. Use a fireplace plug to seal the chimney and stop drafts. If a plug isn’t an option, a fireplace cover can also help block the cold air and keep your home warmer.

4. Rearrange Your Furniture

Make sure your furniture isn’t blocking vents, radiators, or wall units. Heat sources need at least 12 inches of clearance to circulate air effectively. By rearranging furniture to avoid obstructing heat flow, you can maximize the warmth in your home without spending a dime. If you can't move your furniture, or just prefer to stay as is, another option is to purchase a vent extender as seen below.

5. Use Area Rugs

Cold floors can make an entire room feel chilly, especially if they’re above uninsulated basements or crawl spaces. Adding area rugs not only keeps your feet warm but also reduces heat loss through the floor. Just be sure not to cover any heating registers.

6. Insulate Windows and Exterior Doors

Drafty windows and doors are major sources of heat loss. Replace worn-out weatherstripping around doors and windows, and use caulk to seal any gaps around window panes. For an extra layer of insulation, consider using window insulation kits, which are affordable and effective.

Doors: Install weatherstripping or a door sweep to seal gaps and prevent drafts. Door sweeps create a tight seal at the bottom of the door, while fabric door logs can provide a temporary solution. Check the caulking around doors and replace it if it’s degraded.
Windows: Use caulk to seal joints and gaps around windows, but avoid caulking moving parts or weep holes. Window insulation film is another effective option for reducing heat loss.

7. Hang Thermal Curtains

Thermal curtains are a great way to prevent heat loss through windows. On sunny days, open the curtains to let in natural warmth. When it gets chilly, close them to keep the heat inside. Thermal curtains are especially helpful at night when heat loss through windows is most noticeable.

8. Trim Landscaping for Sunlight

If trees or other landscaping block sunlight from reaching your home, consider trimming them back. While shade is helpful in the summer, it can make your home colder in the winter. Allowing more sunlight to reach your home can naturally increase its warmth.

9. Install Outlet Insulators

Electrical outlets and light switches can let in cold air if they’re not insulated properly. Installing foam outlet insulators behind the wall plates is a quick, cheap fix that can make a noticeable difference in reducing drafts.

By following these DIY weatherproofing tips, you can make your home warmer and more energy-efficient without spending a fortune. Stay cozy this winter and keep those heating bills under control!
