Indoor Air Quality Tips for Cold Southwest Connecticut Months

During the cold winter months in Southwest Connecticut, homeowners naturally keep windows closed and rely on heating systems, which can inadvertently reduce indoor air quality. Dry air, dust, and allergens can accumulate, leading to uncomfortable living conditions and potential health issues.

Aire Serv of Southwest Connecticut shares practical indoor air quality tips to maintain a healthy, comfortable home this January and throughout winter.

1. Change or Clean HVAC Filters Regularly

Your HVAC filter is the first line of defense against airborne particles:

  • Replace filters every 30–60 days: Especially if you have pets or allergies.
  • Choose high-efficiency filters: HEPA or MERV-rated filters capture smaller dust and allergen particles.
  • Inspect frequently: Winter use can clog filters faster due to continuous heating cycles.

Clean filters improve airflow and reduce the accumulation of dust and debris indoors.

2. Monitor and Adjust Humidity Levels

Winter air tends to be dry, which can irritate skin, eyes, and respiratory passages:

  • Use a humidifier: Aim for indoor humidity between 40–50% for comfort and health.
  • Check HVAC system compatibility: Some systems have built-in humidifiers or can be retrofitted.
  • Avoid excessive humidity: Too much moisture can encourage mold growth in attics, basements, and ducts.

Proper humidity enhances comfort while protecting your HVAC system.

3. Ensure Proper Ventilation

Even closed homes need fresh air circulation:

  • Open windows briefly when possible: Allow quick exchanges of fresh air without significant heat loss.
  • Use exhaust fans: Kitchens and bathrooms should vent outside to remove moisture and odors.
  • Consider an energy recovery ventilator (ERV): Provides fresh air while maintaining indoor temperature.

Balanced ventilation keeps indoor air cleaner and healthier throughout winter.

4. Clean Ductwork and HVAC Components

Dust and debris in ducts reduce air quality:

  • Professional duct cleaning: Removes accumulated dust, allergens, and debris.
  • Inspect vents and registers: Ensure they are clean and unobstructed for efficient airflow.
  • Check for leaks: Sealed ducts prevent unfiltered air from entering living spaces.

Clean and well-maintained ducts improve efficiency and the quality of the air you breathe.

5. Consider Air Purifiers or Filters

Supplemental air purification can help during long winters:

  • Standalone HEPA purifiers: Target high-use areas like bedrooms or living rooms.
  • Whole-home systems: Integrated with your HVAC system to improve overall air quality.
  • Regular maintenance: Replace filters and clean units to maintain effectiveness.

Using air purifiers complements your HVAC system for healthier indoor air.
