If you're a typical Knox, IN resident your family spends over 90% of their time indoors either at home, school, or work.

IAQ Solutions:

  • Air Filters: Disposable air filters help reduce dust, pollen, pet dander, smoke, bacteria and more. Once installed, you only need to replace the filter every few months, depending on use and size. Upgrading your furnace filters to a high quality media filter will result in cleaner more dust free indoor environments.
  • Air Cleaners: Electronic air cleaners are a more advanced and effective solution than disposable air filters. Air Cleaners capture more airborne particles from the air passing through them and require minimal maintenance. No replacement filters are needed.
  • Air Purifiers and UV Systems: UV air purifiers work with your HVAC systems ductwork utilizing ultraviolet light to address surface contaminants such as mold and bacteria.
  • Humidifiers: Humidifiers help balance winter humidity levels in your home for optimum comfort. Evaporative humidifiers or steam humidifiers are great choices depending on the details of your application.
  • Dehumidifiers: For the summer season, or year round in commercial settings. Excess humidity promotes mold growth and condensation and dehumidifiers will remove moisture to help you maintain desired humidity levels.
  • Heat recovery ventilators (HRVs): HRV's provide fresh air as needed to the indoor environment while maintaining system efficiency particularly in newer and better insulated homes.
  • IAQ Controls: Advanced environment control systems monitor your IAQ and ensure HVAC operation parameters that maximize the quality delivered by your comfort system.
