Indoor Air Quality

The Air Inside Your Home May Be More Polluted Than Outside

Studies show indoor air can be 2–5x more polluted than outdoor air. Dust, allergens, mold spores, VOCs, and bacteria circulate through your HVAC system every time it runs. CoolAir HQ can help.

What Is Indoor Air Quality (IAQ)?

IAQ refers to the quality of air inside your home or building. Poor IAQ causes headaches, allergies, fatigue, and long-term health issues — especially for children, the elderly, and anyone with asthma or respiratory conditions.

Your HVAC system is the lungs of your home. If it's not clean, neither is the air you're breathing. A proper IAQ solution works with your existing system to filter, purify, and balance your indoor air.

Removes allergens, dust mites, and pet dander
Kills bacteria, viruses, and mold spores
Eliminates odors and chemical off-gassing
Balances humidity to prevent mold growth
Protects your HVAC system from buildup

Air Purifiers UV Systems Filtration

🔬

Air Purifiers

Whole-home air purifiers remove up to 99.97% of airborne particles including dust, pollen, mold spores, bacteria, and viruses. Works with your existing HVAC system.

☀️

UV Light Systems

UV germicidal lights installed in your air handler kill bacteria, mold, and viruses before they circulate through your home. Particularly effective in humid climates.

💧

Humidifiers & Dehumidifiers

Too dry causes static and respiratory irritation. Too humid breeds mold. We install whole-home humidity control systems that automatically maintain the ideal level.

🌀

Advanced Filtration

MERV 13+ filtration systems catch particles that standard filters miss. We upgrade your filter system without restricting airflow or stressing your equipment.

🧹

Duct Cleaning

Dirty ducts distribute dust, debris, and allergens every time your system runs. Professional duct cleaning removes years of buildup for dramatically cleaner air.

📊

Air Quality Testing

Not sure what's in your air? We test for common pollutants, allergens, and humidity levels — then recommend the right solution for your specific situation.
