10 Energy-Saving HVAC Tips for Southwest Chicago Homeowners

Your HVAC system accounts for nearly half of your home's energy use. In Southwest Chicago, where we face humid summers and cold winters, that number can climb even higher. Here are 10 practical ways to reduce your energy bills while staying comfortable year-round.

1. Replace Your Air Filter Regularly

A clogged filter forces your system to work harder, increasing energy use by up to 15%. Check your filter monthly and replace it every 1-3 months depending on usage, pets, and allergies.

2. Install a Programmable or Smart Thermostat

Modern thermostats can reduce heating and cooling costs by 10-20% through automated scheduling. Set temperatures back when you're sleeping or away from home.

Recommended setpoints:

• Summer: 78°F when home, 82-85°F when away
• Winter: 68°F when home, 62-65°F when away or sleeping

3. Schedule Annual HVAC Maintenance

Professional tune-ups keep your system running efficiently. During a maintenance visit, technicians clean coils, check refrigerant levels, and ensure proper airflow—all of which improve efficiency.

4. Seal Air Leaks Around Windows and Doors

Air leaks force your HVAC system to work overtime. Use weatherstripping and caulk to seal gaps around windows, doors, and anywhere pipes or wires enter your home.

5. Improve Attic Insulation

Many Burbank and Oak Lawn homes built in the 1950s-1970s have inadequate attic insulation. Upgrading to R-38 or R-49 insulation can reduce heating and cooling costs by 20-30%.

6. Use Ceiling Fans Strategically

Ceiling fans create a wind-chill effect in summer, allowing you to raise your thermostat by 4°F without losing comfort. In winter, run fans clockwise on low speed to push warm air down from the ceiling.

7. Close Vents in Unused Rooms

If you have rooms you rarely use, close the vents and doors to avoid conditioning empty spaces. However, don't close more than 20% of your vents, as this can cause pressure imbalances.

8. Upgrade to a High-Efficiency HVAC System

If your system is 12-15 years old, upgrading to a high-efficiency model can reduce energy use by 20-40%. Look for ENERGY STAR certified equipment with:

• AC: SEER rating of 16+
• Furnace: AFUE rating of 95%+

9. Manage Indoor Humidity

Humid air feels warmer, making you set the thermostat lower. In summer, use a dehumidifier or ensure your AC is properly sized. In winter, add a humidifier to maintain 30-40% humidity, allowing you to feel comfortable at lower temperatures.

10. Keep Outdoor Units Clear

Ensure your outdoor AC unit has at least 2 feet of clearance on all sides. Remove leaves, grass clippings, and debris regularly to maintain proper airflow.

Local Considerations for Burbank & Oak Lawn

Many homes in Southwest Chicago have:

• Short supply runs and restrictive returns
• Original or partially updated ductwork
• Finished basements that affect airflow

These factors can reduce efficiency. A professional duct assessment and balancing can make a significant difference in both comfort and energy costs.
