Your air ducts are the circulatory system of your home’s HVAC. When they leak, sag, disconnect, or deteriorate, your AC works harder, your energy bills climb, and some rooms never get comfortable no matter how low you set the thermostat. Semper Fidelis AC provides professional ductwork inspection, sealing, repair, and replacement throughout Naples and all of Southwest Florida.
Signs You May Have a Ductwork Problem
- Rooms that are consistently warmer or cooler than the rest of the house
- High energy bills that don’t match your usage habits
- Weak or no airflow from certain vents
- Excessive dust buildup on vents and surfaces
- Musty or stale odors coming from the vents
- AC system running constantly without reaching set temperature
- Visible gaps, disconnections, or damage in accessible ductwork
Ductwork Services We Provide
Duct Inspection and Testing
We perform a thorough visual inspection of all accessible ductwork and use pressure testing equipment to measure duct leakage. This gives us a precise picture of where your system is losing conditioned air and what it’s costing you. Every inspection includes a detailed report with findings and recommended repairs.
Duct Sealing
We seal duct leaks using mastic sealant and metal tape — the industry-standard materials recommended by ENERGY STAR. We never use standard duct tape, which degrades quickly in Florida’s heat and humidity. Proper duct sealing can reduce energy bills by 20 to 30% and dramatically improve comfort in rooms that previously received inadequate airflow.
Duct Repair
Disconnected sections, crushed flex duct, and deteriorated insulation are common in Southwest Florida homes, especially in attics where heat and humidity accelerate wear. We repair damaged sections, reconnect disconnected runs, and replace deteriorated insulation to restore proper airflow and efficiency.
Duct Replacement
When ductwork is beyond repair — due to age, pest damage, mold, or poor original installation — full replacement is the most cost-effective solution. We design and install new duct systems to ACCA Manual D standards, properly sized for your home’s layout and your HVAC system’s airflow requirements.
New Duct Installation
For home additions, garage conversions, or homes converting from window units to central air, we design and install complete duct systems from scratch. Every new installation is sized and balanced for optimal comfort and efficiency throughout the entire home.
Why Ductwork Fails Faster in Southwest Florida
Florida’s climate is uniquely harsh on ductwork. Attic temperatures in Southwest Florida can exceed 150°F in the summer, which degrades flex duct insulation and causes the inner liner to crack and separate over time. High humidity promotes mold growth inside ducts, especially when there are leaks that allow unconditioned attic air to enter the system. Pest activity — particularly from rodents and insects — is also a common cause of duct damage in Florida homes. We address all of these issues and use materials rated for Florida’s climate in every installation.
Frequently Asked Questions About Ductwork
How do I know if my ducts are leaking?
The most reliable way to know is a professional duct leakage test. However, common signs include high energy bills, uneven temperatures between rooms, and excessive dust. If your AC runs constantly without reaching the set temperature, duct leakage is one of the first things we check.
How long does ductwork last in Florida?
Flex duct in Florida attics typically lasts 15 to 25 years, but can degrade faster in extreme heat or high humidity. Metal ductwork lasts longer but is susceptible to rust and disconnection over time. If your home is more than 20 years old and has never had a duct inspection, it’s worth having one done.
Can duct sealing really lower my energy bill?
Yes. The U.S. Department of Energy estimates that leaky ducts waste 20 to 30% of conditioned air before it reaches the living space. In a home where the AC runs 10 to 12 months per year, that waste adds up significantly. Most customers see a noticeable reduction in their FPL bill within the first month after duct sealing.
