1. Let the Sun Do the Work

Even on very cold days, Chicago receives bright winter sunlight.

• Open your curtains during the day, especially on south-facing windows
• Allow natural light to warm your apartment
• Close curtains at night to keep the warmth inside

For even better insulation, consider thermal curtains. You can browse options here:

• Home Depot
• Target

2. Seal Drafts Around Windows and Doors

Older Chicago buildings often have drafty windows and doors where warm air escapes and cold air creeps in.

Heat loss commonly occurs around:

• Window frames
• Door frames
• Sliding balcony doors

Easy and affordable fixes include:

• Weather stripping
• Window insulation film
• Door draft stoppers

Here are direct links to helpful products:

• 3M Window Insulation Kit
• Door draft stopper
• Weather stripping kit

If a draft persists even after sealing, let your property manager know so it can be inspected.

3. Use Rugs to Warm Up Floors

Hardwood and tile floors become very cold in the winter. Placing area rugs helps reduce heat loss and makes walking around far more comfortable.

4. Keep Vents and Radiators Clear

If you have forced-air heat, check that vents are not blocked by furniture or curtains.

If your building uses radiators, which is common in older Chicago units, make sure nothing is placed on top of the radiator and that there is space around it so warm air can circulate efficiently.

Good airflow improves heating performance and overall comfort.

5. Reverse Your Ceiling Fans

Most ceiling fans include a small switch that changes their direction.

In winter, set your ceiling fan to spin clockwise at a low speed. This gently pushes warm air downward without creating a breeze.

6. Use a Programmable Thermostat Wisely

A programmable or smart thermostat can help reduce heating costs while maintaining comfort.

Try setting:

• Lower temperatures while you sleep
  
• Lower temperatures while you are away
  
• A warm-up schedule before you wake or return home

7. Close Doors to Unused Rooms

Closing off unused spaces helps concentrate warmth in the rooms you use most often. This helps your heating system work more efficiently and improves comfort.

8. Maintain Healthy Humidity Levels

Chicago winters are extremely dry. Keeping indoor humidity at a healthy level increases comfort and helps retain heat.

Ways to add humidity include:

• Using a humidifier
• Placing a bowl of water near a radiator

Weather.com provides useful guidance on ideal indoor humidity levels.

9. Know Chicago’s Heating Requirements

Chicago has specific heating minimums that landlords must follow:

• At least 68°F from 8:30 AM to 10:30 PM
• At least 66°F from 10:30 PM to 8:30 AM

You can view the official Chicago Heat Ordinance here.

If your apartment feels colder than these temperatures, contact your property manager right away.
