Frequently Asked Questions
What are the signs that my home has poor indoor air quality?
You might notice persistent allergy symptoms like sneezing or itchy eyes while inside, excessive dust buildup on furniture shortly after cleaning, lingering odors, or visible mold growth in damp areas. High humidity levels or a “stuffy” feeling in certain rooms can also indicate that your home’s air quality and ventilation need attention.
How does an HVAC system affect indoor air quality?
Your HVAC system is the lungs of your home; it circulates air through every room. If the system is dirty or lacks proper filtration, it can spread dust and allergens continuously. Conversely, a well-maintained system with upgraded filtration or purification add-ons can actively clean the air, removing pollutants and regulating humidity to create a healthier environment.
What is the difference between air filtration and air purification?
Air filtration involves trapping airborne particles (like dust and pollen) in a physical filter media, preventing them from circulating. Air purification goes a step further by actively neutralizing or killing contaminants, such as bacteria, viruses, and odors, often using UV light or ionization technology. We often recommend a combination of both for the best results.
