Air Duct Services: Sanitization & Duct Replacement
Your ductwork is the hidden circulatory system of your home. When it is clean, sealed, and properly sized, it delivers cool, comfortable air to every room and keeps your energy bills in check. When it is dirty, leaky, or undersized, it can spread odors, harbor mold, drive up costs, and leave some rooms hot while others stay freezing. At Metro Air, a family-owned company serving Pinellas County since 1973, we offer two specialized duct services that go beyond a standard AC repair: air duct sanitization and full duct replacement.
We are a Trane Comfort Specialist, fully licensed in Florida (CMC1250444), and we hold an A+ rating with the BBB. From our shop in Largo, we serve homeowners across all of Pinellas County with honest recommendations and clean, careful workmanship.
Our Air Duct Services
- Air duct sanitization — We fog your duct system with an EPA-registered product that is safe for your family and pets, neutralizing the mold, mildew, and musty odors that thrive in humid Florida attics. It is a fast, effective way to refresh the air your system circulates.
- Duct replacement — Old, leaky, or undersized ducts quietly waste the air you pay to cool. We design and install new, properly sealed and correctly sized ductwork to restore airflow, improve indoor air quality, and lower your monthly bills.
Air Duct Sanitization for Florida Homes
Florida humidity does not stop at your front door. Warm, damp air gets into attic ductwork and creates the perfect environment for mold, mildew, and bacteria to grow on duct surfaces. Once that happens, every time your system runs it can push those spores and that telltale musty smell throughout your living space.
Our sanitization process uses a fogging treatment with an EPA-registered antimicrobial chosen because it is safe to use around children and pets. It coats the interior of the duct system to kill mold and mildew at the source and eliminate lingering odors — not just mask them. If anyone in your household deals with allergies, asthma, or unexplained stuffiness, cleaner ducts can make a noticeable difference in how your home feels.
Duct Replacement for Better Comfort & Lower Bills
Even a brand-new, high-efficiency air conditioner cannot perform well through bad ductwork. Many Pinellas County homes still run on original ducts that have developed leaks at the seams, sagging flex runs, crushed sections, or undersized layouts that choke airflow. Industry studies estimate that leaky ducts can waste 20 to 30 percent of the air your system moves — air you are paying to cool, escaping into the attic.
When we replace your ducts, we size and seal the new system to match your home and your equipment. The result is more even temperatures room to room, cleaner indoor air, quieter operation, and lower utility bills. It is one of the most overlooked upgrades a homeowner can make, and it often pays for itself in comfort and efficiency.
Signs You May Need Duct Service
Ductwork problems tend to hide in the attic, so the warning signs usually show up inside your home instead. Call us if you notice any of the following:
- Uneven temperatures — some rooms never cool down while others feel like a refrigerator.
- Excessive dust — you dust constantly and it keeps coming back, suggesting leaks pulling attic debris into the airflow.
- Musty or stale smells — a damp, moldy odor when the AC kicks on points to contamination inside the ducts.
- Rising energy bills — a system that runs longer and costs more without any change in your habits.
- Weak airflow — vents that barely push air, even when the blower is running on high.
Frequently Asked Questions
Is air duct sanitization safe for my kids and pets?
Yes. We use an EPA-registered product specifically chosen because it is safe for families and pets when applied properly. Our technicians fog the duct system and let it do its work so your home is comfortable to return to.
How do I know if I need duct cleaning or full duct replacement?
Sanitization is the right fix when your ducts are structurally sound but harboring mold, mildew, or odors. Replacement makes sense when ducts are leaking, undersized, crushed, or simply worn out and dragging down your comfort and efficiency. We will inspect your system and give you an honest recommendation — no pressure.
Will new ductwork really lower my energy bills?
It can. Leaky and undersized ducts let cooled air escape into the attic and force your system to run longer. Properly sealed, correctly sized ducts deliver more of the air you pay for into your rooms, which improves comfort and typically reduces cooling costs.
