Full Residential IAQ HVAC Inspection by NADCA Certified Professional
Before we can provide any quotes or perform work on your home’s ductwork or ventilation system, a certified inspection must be completed by Mitchell Stonebarger—the founder of HYPER and the trusted name in indoor air quality across the Midwest. In the humid Midwest climate, 99.9% of ductwork is contaminated with mold, and most HVAC systems contain fiberglass insulation inside the air handler and ductwork. Over time, this insulation breaks down, releasing fiberglass particles into your air—often mistaken for dust. Some homes may even contain asbestos-lined ductwork, especially those built before the 1980s, which requires specialized handling. ⚠️ Important: Excessive dust in the home is rarely caused by buildup alone—it’s often due to leaks and cracks in your ductwork. These allow contaminated air from crawlspaces, attics, wall cavities, and slabs to mix with your indoor air. That’s why sealing the ductwork is just as criticalas cleaning it. 🚫 Never trust discount “coupon” companies offering $49–$199 air duct cleanings with no inspection, no certification, and shady upselling practices. These shortcuts can damage your system and do more harm than good.What You’ll Get With Your $225 Inspection (Per System):
✅ Air Quality Analysis
We use advanced diagnostic tools to measure:
This data is analyzed by our proprietary software, helping determine whether cleaning or restoration is necessary.
We seal off the vents and use specialized equipment to test for air leaks—the most common cause of dusty homes, allergy symptoms, and temperature imbalances. You’ll also receive internal photos showing the condition of your ductwork and whether cleaning, sealing, or encapsulation is needed.
We thoroughly examine your air handler and duct system for mold, soot, fiberglass, and even asbestos—all of which can drastically impact your health and air quality.
Why It Matters
According to This Old House, the average cost of air duct cleaning can range greatly. But without a proper inspection, you risk overpaying for unnecessary services or, worse, allowing uncertified contractors to damage your system. That’s why we follow strict NADCA and IICRC standards—giving you real answers, not guesswork.
