Indoor air quality (IAQ) is often overlooked, but it has a huge impact on your family’s health, comfort, and even your HVAC system’s efficiency. In a city like Chicago, with long winters and hot, humid summers, indoor air can easily become polluted by dust, allergens, and contaminants.

At Shad Heating and Cooling, we help homeowners maintain clean, healthy air while keeping their heating and cooling systems running efficiently. In this post, we’ll cover practical tips to improve indoor air quality in Chicago homes and explain how your HVAC system plays a key role.

Why Indoor Air Quality Matters in Chicago

Chicago homes often face IAQ challenges:

• Dust and allergens from urban environments
• Mold and mildew from humidity and poor ventilation
• Pet dander and household chemicals
• Poorly maintained HVAC systems

Improving indoor air quality not only helps prevent allergies and respiratory issues but also protects your HVAC system from strain and damage.

Tip 1: Replace HVAC Filters Regularly

The simplest way to improve indoor air quality is with clean filters. Recommendations:

• Standard 1-inch filters: replace every 30–60 days
• Thick media filters: replace every 3–6 months
• Homes with pets or allergies: replace more frequently

Clean filters trap dust, pollen, and other particles before they circulate throughout your home.

Tip 2: Schedule Professional HVAC Maintenance

A professional maintenance visit does more than keep your system running—it improves indoor air quality:

• Cleans evaporator and condenser coils
• Checks ductwork for leaks or blockages
• Ensures proper airflow throughout the home
• Tests for carbon monoxide and other safety hazards

Routine maintenance keeps your HVAC system efficient and your air clean.

Tip 3: Consider Air Purifiers or UV Lights

Adding an air purifier or UV light to your HVAC system can remove bacteria, viruses, and fine particles from the air. Many Chicago homeowners find these devices helpful for:

• Allergy relief
• Reducing mold spores
• Improving overall indoor air quality

Tip 4: Control Humidity

Humidity impacts both comfort and air quality:

• Low humidity in winter can dry skin and irritate respiratory systems
• High humidity in summer promotes mold and dust mites

Use a humidifier in winter and a dehumidifier or AC system with humidity control in summer to maintain healthy levels.

Tip 5: Keep Your Home Clean and Ventilated

Small habits make a big difference:

• Vacuum and dust regularly
• Keep vents and registers unobstructed
• Open windows when outdoor air is clean
• Avoid smoking indoors

Good airflow, combined with a properly maintained HVAC system, improves air quality dramatically.
