Living in an older apartment doesn’t mean you have to settle for sky-high heating costs every winter. Drafty windows, outdated radiators, and single-pane glass can all drain warmth and money but a few renter-friendly tricks can make a real difference.
Many solutions cost less than $30 and don’t require your landlord’s permission. From simple insulation fixes to smart thermostat use, these steps help you stay cozy while cutting down on wasted energy.
1. Add removable window insulation film
Plastic window film creates an invisible barrier that traps warm air inside. It’s easy to apply with a hair dryer and peels off cleanly in spring, no tools required.
Even single-pane windows feel tighter and less drafty afterward. For renters on upper floors, sealing just the leakiest windows can noticeably cut heat loss and improve comfort.
2. Use thermal curtains or layered drapes
Heavy curtains help block cold air at night and retain heat during the day. Look for insulated or blackout panels that are easy to hang on tension rods.
Keep them open on sunny days to take advantage of free heat, then close them as soon as the sun sets. The extra layer helps stabilize indoor temperature and ease furnace workload.
3. Seal door gaps with draft stoppers
Cold air often sneaks in under doors, especially in hallways and shared entryways. A door sweep or weighted draft snake can stop those leaks immediately.
Choose models that screw into the door bottom or slide under without hardware so you can remove them easily when you move out.
4. Layer rugs over bare floors
Wood and tile floors lose heat faster than carpet, making feet cold and forcing you to raise the thermostat. Area rugs create instant insulation.
Thick rugs with pads underneath trap heat while cutting down on drafts from floorboards, especially useful in prewar buildings with high ceilings.
5. Switch ceiling fans to clockwise
Set ceiling fans to spin slowly clockwise during winter. This pushes warm air down from the ceiling and keeps it circulating around the room.
It’s an easy tweak that can make a noticeable difference in older units where radiators heat unevenly. Just remember to return the setting to counterclockwise in spring. For added insulation and sound control, consider installing acoustic ceiling tiles, which can help retain warmth while also improving room acoustics.
6. Bleed your radiator (with permission)
Trapped air bubbles prevent radiators from heating fully. If your building uses steam or hot-water radiators, bleeding them can restore warmth and balance the system.
Ask your landlord or super before doing it yourself, some buildings require maintenance to handle it safely. Once done, your unit will heat faster and more evenly.
7. Install a smart plug thermostat
If you can’t alter the building’s main thermostat, a plug-in smart thermostat for space heaters gives you programmable control. Some models connect through Wi-Fi for scheduling.
Use it to cut heat when you’re out and warm things up before you get home, helping reduce bills without sacrificing comfort. Always follow safety guidelines for space heaters.
8. Close off unused rooms
In large apartments, heating unused spaces wastes energy. Keep doors and vents shut in rooms you don’t use daily so your system can focus on occupied areas.
This simple change helps old radiators and baseboards heat more efficiently while keeping living spaces comfortable. Reopen doors occasionally to prevent musty air.
9. Cover radiators with reflective panels
Radiator heat often escapes into walls instead of rooms. Aluminum foil or reflective panels behind units push warmth back where it’s needed.
Precut panels are renter-safe and remove easily in spring. They’re especially effective on exterior walls where heat loss is greatest.
10. Adjust furniture placement
Don’t block radiators or vents with couches or curtains. Open airflow lets warm air circulate freely and prevents wasted energy.
Even shifting furniture a few inches away from walls can help distribute heat evenly and make older systems perform better.
11. Add temporary weatherstripping around windows
Peel-and-stick foam or rubber weatherstripping fills cracks and seals drafts without damaging paint. It’s removable and ideal for older sash windows.
Focus on the window edges that rattle or feel cold to the touch. You’ll notice immediate comfort gains, especially on windy days.
12. Use a humidifier to feel warmer
Dry winter air makes rooms feel colder than they are. Adding humidity helps the air retain warmth, letting you stay comfortable at lower thermostat settings
Small plug-in humidifiers or even bowls of water near heat sources can help. Just keep moisture moderate to avoid window condensation or mold.
13. Layer up smartly indoors
Before cranking up the heat, try adding soft fleece layers or thick socks. Extra clothing helps trap body heat so you can lower the thermostat a few degrees.
Even lowering it by two degrees can make a difference on monthly bills. A cozy robe or slippers can keep you comfortable without spending more on energy.
14. Ask your landlord about utility upgrades
Renters often overlook that property owners benefit from energy improvements too. Politely ask if weatherstripping, new thermostats, or radiator maintenance are possible.
Some cities offer rebates for landlords who upgrade insulation or heating systems, and your request might prompt useful building-wide improvements.
15. Switch to LED bulbs and efficient lighting
Older apartments often rely on incandescent or halogen bulbs that waste energy as heat. Replacing them with LEDs cuts electricity use by up to 80% and gives off less unwanted warmth, keeping your space more comfortable and balanced.
LEDs also last for years, which means fewer replacements and lower maintenance costs. Choose warm white tones for a cozy glow that complements winter evenings without straining your electric bill.
