Indoor Air Quality Services in Greenville, SC

If your home smells musty, feels stale, or causes frequent sneezing or sinus irritation, your indoor air quality may be to blame. Pollutants like dust, pet dander, mold spores, and VOCs can circulate through your HVAC system – making your air less healthy and your home less comfortable.
At All Star HVAC and Home Service, we provide advanced air purification and filtration solutions that help Upstate homeowners breathe easier. Our Nu-Calgon iWave Air Scrubbers and REME-HALO systems eliminate airborne contaminants and odors, delivering cleaner, fresher air throughout your home.

Why Indoor Air Quality Matters

The EPA estimates that indoor air can be 2–5 times more polluted than outdoor air, especially in tightly sealed homes. In Greenville’s humid climate, this problem is compounded by excess moisture and airborne particles that cling to dust and ductwork.

Poor air quality can lead to:
  • Persistent musty or stale odors
  • Dust buildup around vents or furniture
  • Allergy flare-ups or worsening asthma symptoms
  • Dry throats or headaches from chemical irritants
  • Uneven humidity levels affecting comfort

If your home never smells “fresh,” or you notice musty odors coming from vents, your HVAC system may be circulating contaminated air – and it’s time to take action.

Our Indoor Air Quality Solutions

We deliver customized solutions that target the root cause of indoor air pollution, not just the symptoms.
  • Nu-Calgon iWave Air Scrubber Installation
    The Nu-Calgon iWave is a state-of-the-art air purification system that uses ionization to neutralize airborne particles, allergens, and bacteria. It’s a self-cleaning, low-maintenance system that installs directly inside your HVAC system - providing whole-home air purification without filters to replace.
    • Actively reduces mold spores, dust, smoke, and odors
    • Helps eliminate musty or stale air in living spaces
    • Improves air freshness and overall HVAC efficiency
  • REME-HALO Air Purifier Installation
    The REME-HALO uses advanced hydrogen peroxide plasma technology to kill up to 99% of airborne contaminants. It targets viruses, bacteria, and VOCs (volatile organic compounds) throughout your home, helping your air stay clean and crisp year-round.
    • Neutralizes germs and airborne chemicals
    • Reduces lingering cooking and pet odors
    • Promotes a healthier environment for allergy sufferers
  • Ductwork Cleaning, Sealing & Replacement
    Musty odors often come from your HVAC ductwork. Moisture, dust, and organic matter can collect inside ducts over time. We inspect, repair, and replace duct systems to restore clean airflow and remove odor-causing buildup at the source.
  • Humidity & Ventilation Balancing
    Balanced humidity is key to clean air. We offer whole-home dehumidifiers to control moisture and improve comfort, preventing mold and mildew from developing in hidden areas like crawlspaces or ductwork.

Frequently Asked Questions About Allergy Relief

Musty smells often come from moisture buildup or microbial growth inside ductwork or HVAC components. Cleaning, sealing, and purifying your duct system can eliminate the source of the odor and prevent it from returning.
