Indoor Air Quality Testing Oklahoma City
You can't see it. But you can measure it.
You've been waking up with headaches. Brain fog that wasn't there before. Fatigue
that doesn't make sense. The doctor says your bloodwork is fine. But something's off — and it's worse at
home.
I'm Derrick Fredendall. I test the air you're breathing. Not a guess. Not a
sniff test. Actual measurements from certified lab analysis.
You're Here Because Something Doesn't Add Up
Click what applies to you:
What You're Actually Breathing
Indoor air can be 2-5 times more polluted than outdoor air. Most people spend 90% of their time indoors. Here's what testing can reveal:
Common Indoor Air Contaminants
VOCs (Volatile Organic Compounds)
Gaseous chemicals released from paint, flooring, furniture, cleaning products, and building materials. Off-gassing is highest in new construction. Causes headaches and respiratory irritation.
Particulate Matter (PM2.5/PM10)
Microscopic particles from dust, pet dander, cooking, and outdoor pollution. Particles under 2.5 microns are small enough to enter your bloodstream.
Mold Spores
Airborne reproductive particles from active mold growth. Even when you can't see mold, elevated spore counts indicate a problem somewhere in the building.
CO₂ (Carbon Dioxide)
Exhaled by occupants. High levels indicate poor ventilation and can cause fatigue, headaches, and difficulty concentrating. Common in tight new construction.
Why Oklahoma Homes Have Air Quality Issues
New Construction: Energy-efficient homes are sealed tight. Great for utility bills. Bad for air exchange. Off-gassing chemicals have nowhere to go.
Climate Swings: We go from 20°F to 80°F in a week. HVAC systems work overtime. Condensation forms where it shouldn't.
Storm Damage: Water intrusion after tornadoes and hail leads to hidden moisture problems that affect air quality for years.
Older Homes: Ductwork that hasn't been cleaned in decades. Hidden mold from decades of Oklahoma humidity.
Why testing matters: You can't fix what you can't measure. Data tells you what's elevated, what's normal, and whether your symptoms have an environmental explanation.

Your Testing: What to Expect
Here's exactly what happens from booking to results.
After scheduling, you'll receive confirmation with my contact info. Close windows and doors 12 hours before testing for accurate results.
I show up on time, listen to your concerns, and understand what symptoms you're experiencing and when they started.
Outdoor control sample first — this is the baseline. Then indoor samples in problem areas: bedrooms, living spaces, HVAC return.
Temperature and humidity throughout the home. CO₂ in occupied spaces. Visual check of HVAC and any obvious moisture sources.
Written report with lab results, interpretation, and recommendations. What's elevated, what's normal, what to do about it.
Why I Don't Sell Air Purifiers
Some air quality testers are also air purifier salespeople. Or HVAC cleaning companies. Or mold remediators. That creates a problem.
If the same person who tests your air also sells the solution, they have a financial incentive to find problems. And to recommend expensive fixes.
I don't sell air purifiers. I don't clean ducts. I don't do remediation.
I'm the measurement. Someone else is the fix.
- No pressure to find problems that aren't there
- No product sales or "whole house" systems
- No conflict of interest
- No "discovering" you need more testing

Air Quality Problems We See in Oklahoma City
The New Construction Headaches
A Norman couple moved into their new build and immediately started experiencing headaches and fatigue. Testing revealed VOC levels four times typical outdoor levels — off-gassing from paint, flooring, and cabinets.
The "Sick Building" Office
An Oklahoma City business had employees with ongoing respiratory complaints. Air testing found elevated mold spores and CO₂ levels indicating poor fresh air exchange.
The Post-Renovation Problems
A Moore family renovated their kitchen — new cabinets, flooring, and paint. Within weeks, their child developed persistent coughing. Testing confirmed elevated formaldehyde from pressed-wood cabinets.
The Mystery Fatigue
An Edmond homeowner had fatigue and brain fog for months. Normal bloodwork. Air testing revealed elevated mold spores — traced to a slow roof leak creating hidden growth.
