Why Indoor Air Quality Matters
- Respiratory issues
- Allergies and asthma symptoms
- Fatigue and headaches
- Long-term health concerns
Common Causes of Poor IAQ
- Inadequate ventilation
- Dust, pollen, and allergens
- High or low humidity levels
- Mold and mildew growth
- Outdoor pollutants entering the building
- Outdoor pollutants entering the building
- Chemical pollutants (VOCs) from cleaning products, paints, and materials
Common Causes of Poor IAQ
Several factors can reduce indoor air quality, including:
- Inadequate ventilation
- Dust, pollen, and allergens
- High or low humidity levels
- Mold and mildew growth
- Outdoor pollutants entering the building
- Outdoor pollutants entering the building
- Chemical pollutants (VOCs) from cleaning products, paints, and materials
How to Improve Indoor Air Quality
1
Maintain Your HVAC System
Regular maintenance helps prevent the buildup and circulation of pollutants.
- Change air filters regularlyÂ
- Clean ductwork as neededÂ
- Schedule professional HVAC inspectionsÂ

4
Improve Ventilation with an ERV
An Energy Recovery Ventilator (ERV) brings in fresh air while maintaining energy efficiency.
- Replaces stale indoor air with filtered outdoor airÂ
- Balances temperature and humidityÂ
- Ideal for tightly sealed, energy-efficient homes
5
Control Indoor Humidity
Balanced humidity improves comfort and prevents contaminants.
- Use dehumidifiers in humid conditionsÂ
- Use humidifiers in dry environments
- Helps prevent mold and bacteria growth
6
uv lights
- Uses ultraviolet (UV) light to improve air quality inside HVAC systems
- Targets and neutralizes airborne bacteria, viruses, and mold
- Helps prevent microbial growth on coils and other internal components
- Works continuously as air circulates through the system
- Contributes to cleaner, healthier indoor air
7
Install an Air Purifier
Simple habits can make a big difference:
- Use low-VOC products
- Keep your space clean and dust-free
- Address mold or moisture issues quickly
