The air inside your St Louis home can be two to five times more polluted than outdoor air, according to the EPA. Missouri Furnace & Air Conditioning helps you breathe easier with comprehensive indoor air quality (IAQ) solutions tailored to your family's needs. From humidity control to air purification, we address the root causes of allergies, asthma, dust, mold, and chemical off-gassing.
Our IAQ services start with a free in-home assessment to measure humidity levels, detect volatile organic compounds (VOCs), and test airflow. Based on the results, we recommend solutions like whole-house humidifiers and dehumidifiers to maintain optimal 30-50% humidity—reducing mold growth and making your home feel more comfortable at lower thermostat settings. For airborne particles and germs, we install electronic air cleaners, UV germicidal lights, and HEPA filtration systems that capture 99.97% of pollutants.
We also specialize in ventilation solutions such as energy recovery ventilators (ERVs) that bring in fresh outdoor air without losing heating or cooling energy. If you notice stale odors, excessive dust, or worsening allergy symptoms, it's time to improve your indoor air quality. Our technicians will design a system that works seamlessly with your existing HVAC equipment, and we offer financing options to make clean air affordable.
