You may have heard that indoor air is two to five times more polluted than outdoor air, but what exactly is causing the contamination? Many invisible particles and gases can impact your comfort, health, and HVAC system.
Common Indoor Air Pollutants
- Pollen
- Dust and Dust Mites
- Pet Dander
- Mold Spores
- Volatile Organic Compounds (VOCs)- such as paint fumes and harsh cleaners
- Cooking Fumes and Smoke
- Bacteria and Viruses
How Pollutants Affect Your HVAC System & Health
Even one of these contaminants can cause health issues and reduce the efficiency and lifespan of your HVAC system. Here’s how:
- Clog filters – Restrict airflow and reduce energy efficiency
- Humidity imbalances – Cause discomfort and promote mold growth
- Overworked equipment – Shorten your system’s life expectancy
- Pollutant buildup in ductwork– Spread contaminants throughout your home or business
How to Improve Indoor Air Quality
The good news? You can make simple, effective upgrades to create a healthier, more comfortable indoor environment while also protecting your HVAC system.
Before making changes, we recommend an indoor air quality test to identify any urgent issues such as mold growth, that may need immediate attention.
Once you’ve assessed your air quality, consider these solutions:
High-Quality Air Filters – Choose filters with a higher MERV rating to capture more particles
HVAC-Integrated UV Lights – Kill bacteria, mold, and viruses within your system.
Duct Sealing & Cleaning – Prevent pollutants from circulating through your space.
Whole-Building Air Purifiers – Enhance filtration and remove airborne contaminants.
Ventilation Upgrades – Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs) bring in fresh air while maintaining efficiency.
Humidifiers & Dehumidifiers – Maintain optimal humidity levels (30–50%) for comfort and health.
