Common Signs You Need Air Duct Repairs
Even well-built duct systems wear down over time. Here’s how to tell if something’s off:
Uneven Room Temperatures
Hot and cold zones can mean certain ducts aren’t delivering air as they should. In older homes, duct damage or poor insulation can easily throw off comfort from floor to floor.
Noises Coming From Ducts or Vents
Popping or whistling sounds from your vents are often caused by shifting metal, loose connections, or high air pressure, often a symptom of duct damage or poor sealing.
Musty, Unpleasant Odors
A musty scent coming from your vents isn’t just unpleasant, it’s often a sign of moisture buildup inside the duct system. That damp, stale air can worsen after storms or during long stretches of AC use.
Dust Buildup Around Vents
Heavy dust near vents isn’t just a cleaning issue, as it’s often a symptom of duct leaks drawing in unfiltered air. This is common in homes with older ductwork or open crawlspaces.
Rising Energy Costs
If your utility bills are climbing but your comfort hasn’t improved, leaking ducts may be the cause. Escaping conditioned air forces your system to work harder, driving up monthly energy use.
Excess Humidity or Condensation Near Vents
Rust spots or wet marks near vents often mean your ducts aren’t sealed well. That trapped moisture can promote mold, rot insulation, and wear down the duct system from the inside out.
What Factors Influence the Cost of Air Duct Repairs?
Air duct repair costs can vary depending on your home’s design, materials, and the scope of damage.
Here’s what we evaluate:
Type of Ductwork Material
Different duct types require different repair approaches:
- Flexible Non-Metallic Ducts: Prone to tears and punctures
- Sheet Metal Ducts: Durable but may rust or corrode
- Fiberglass-Lined Ducts: Require special handling to avoid fiberglass exposure
- Aluminum Ducts: Lightweight but susceptible to crushing or disconnecting
Root Cause of the Problem
We pinpoint the underlying issue before starting any duct repair service:
- Broken or clogged vents
- Mold or mildew inside ducts
- Crushed or collapsed sections
- Loose or disconnected joints
- Pest infestations
- Visible holes, tears, or corrosion
- Tape degradation and unsealed gaps
- Moisture buildup from excessive condensation
Location of the Damaged Ducts
Accessibility can impact repair complexity:
- Inside wall cavities
- Under raised foundations or mobile homes
- Basements in historic districts or multi-zone systems
- Whole-home duct networks needing sectional repairs
Frequently Asked Questions
How do I know if my ductwork is losing air or leaking?
You might notice hot or cold spots, whistling noises, excessive dust, or rising utility bills. We use diagnostic tools to detect pressure loss and pinpoint leaks.
What repair options are available for leaking air ducts?
Repairs depend on what we find. In some cases, mastic or foil tape seals the leak. In others, we may recommend duct section replacements or Aeroseal to seal your system from the inside.
What role does insulation play once air ducts are sealed?
Sealing stops air leaks, but insulation helps maintain temperature and reduces condensation risks. We often rewrap or upgrade insulation during repair for added efficiency.
Can high humidity levels cause ductwork to deteriorate faster?
Yes. Persistent moisture from outdoor humidity and condensation inside the system can accelerate rust, corrosion, and mold growth, especially in older metal ducts.
Is Aeroseal a good option for duct sealing in older homes with limited crawlspace access?
For homes with crawlspaces or wall-embedded ductwork, Aeroseal offers a non-invasive way to restore efficiency. It’s ideal for many older homes.
