Do You Have Mold and Mildew In Your Ducts?
Here in Wilmington, we’ve got a lot going for us—beaches, seafood, and warm coastal breezes. But all that humidity? That’s the trade-off. At One Hour Magic, we get a steady stream of calls about musty smells, stuffy air, and strange allergy flare-ups. And one of the most common culprits behind those issues? Mold and mildew in AC ducts.
So let’s answer the question: How common is mold and mildew in AC ducts in Wilmington? In short—very. The combination of high humidity, warm air, and long AC run times creates the perfect storm for mold to show up and stick around.
Why It’s So Common Here
Wilmington sits on the coast, and our climate stays humid nearly year-round. Even when temperatures dip, moisture doesn’t always drop with it. That constant humidity puts pressure on HVAC systems to pull double duty—not just cooling the air but removing moisture too.
Inside your ductwork, condensation forms when warm, damp air meets cold duct surfaces. Add a little dust, and you’ve got a mold buffet. And because ducts are tucked away behind walls and ceilings, the problem can grow without being seen.
What Mold and Mildew in Ducts Can Do
The trouble with mold isn’t just the smell—it’s how it affects your air and your health.
Here’s what we’ve seen mold do to homes across Wilmington:
- Trigger allergies and asthma in both kids and adults
- Create persistent musty odors that don’t go away no matter how many candles you burn
- Circulate spores through the entire home every time the fan kicks on
- Reduce airflow by coating the inside of ductwork with grime
- Damage insulation and ducts if moisture sits for too long
The worst part? Most homeowners don’t know they have a problem until it spreads.
How We Spot Mold and Mildew in Your HVAC System
At One Hour Magic, we don’t play guessing games. When you call us out for a duct issue, we go through a process that’s designed to find the cause—not just patch the symptom.
Step 1: We Ask Questions
We listen first. Have you noticed a smell? Are family members sneezing more often? Has your power bill crept up without reason?
Step 2: We Inspect the Ducts
We inspect your ductwork using lights and cameras. We look for discoloration, moisture buildup, and dust clusters that often act as mold beds.
Step 3: We Check the Indoor Unit
We check the evaporator coil, drain pan, and drain line—three places where mold commonly grows in AC systems in Wilmington.
Step 4: We Measure Humidity
If your home’s humidity is regularly above 55%, your ducts are more likely to be mold-friendly. We check readings around the house to find hot spots.
When to Call Us for Help
You don’t need to see green fuzz to call for backup. Mold and mildew like to stay hidden, but the signs usually appear in other ways.
Give us a call if:
- You smell a musty or sour odor every time the AC turns on
- Your family deals with frequent sneezing, coughing, or headaches
- Your duct vents have visible spots or dust buildup
- You see moisture around the vents or ceiling stains near ductwork
- You haven’t had your ducts inspected or cleaned in years
We’ve worked in homes all across Wilmington—from new construction to century-old cottages. Mold doesn’t discriminate.
How We Fix the Problem
We don’t just clean and run. Our job is to break the cycle so the mold doesn’t come back two months later. Here’s how we do it:
Step 1: Remove the Mold
We use industry-approved vacuums and antimicrobial treatments to clear out spores, dust, and debris from inside your ducts. It’s safe, clean, and thorough.
Step 2: Fix the Source of Moisture
Whether it’s a clogged drain line, dirty evaporator coil, or uninsulated duct leaking in the attic, we find the root of the moisture and fix it.
Step 3: Seal Leaks and Gaps
We seal up any places where outside air is getting into your duct system—especially in crawl spaces and attics. This keeps moisture from creeping back in.
Step 4: Test and Balance Your System
We make sure your AC system is drying the air properly and running at the right pressure. If something’s off, it won’t take long for the problem to come back.
FAQs
Is mold in my AC ducts dangerous?
It can be. Some molds cause allergy symptoms, and prolonged exposure can make people sick—especially children or anyone with a respiratory condition.
Can I clean my ducts myself?
Not really. Surface cleaning won’t reach deep into the ductwork, and using household cleaners inside vents can make things worse. We use professional tools for a reason.
How often should ducts be cleaned in Wilmington?
If you’ve had mold issues, every 3–5 years is smart. Otherwise, have them inspected yearly as part of a full AC tune-up.
Will a dehumidifier help?
Yes. A whole-house dehumidifier can lower moisture levels and stop mold from growing inside your ducts and air handler.
What if I have mold but can’t smell it?
That happens. Not all mold has a strong odor. If you’re experiencing unexplained symptoms or have moisture issues, it’s worth checking anyway.
