Ductwork Challenges in Kaplan
Kaplan’s location in southern Vermilion Parish puts it squarely in the zone where Gulf Coast humidity and heat hit hardest. Your HVAC system runs the majority of the year, and the ductwork carrying conditioned air through your home takes that same punishment day after day.
Many homes in Kaplan were built in the 1960s through the 1980s, a period when ductwork installation standards were looser than they are today. Ducts were often undersized, connections were made with tape instead of mastic, and insulation was treated as optional. Homes from that era that still have their original duct systems are almost certainly losing a significant portion of their conditioned air.
Even newer homes aren’t immune. Flex duct installed in Kaplan attics during the building activity of the 2000s has now had 15 to 20 years of exposure to 140-degree attic temperatures, and the effects of that heat show up as sagging runs, brittle outer jackets, and loosened connections.
Signs Your Kaplan Home Has Duct Problems
You don’t need to climb into your attic to suspect duct issues. The symptoms show up in your living space.
Temperature differences between rooms are the most common indicator. If your living room cools to 72 degrees while your back bedroom sits at 78, the duct serving that bedroom may be disconnected, kinked, or undersized. Before assuming your AC unit is the problem, the ductwork deserves investigation.
High humidity indoors despite running the AC often points to duct leaks pulling in unconditioned attic air. Your AC system dehumidifies as it cools, but if leaks allow hot, humid attic air into the return side of your duct system, that moisture enters your home faster than the AC can remove it.
Dust at the registers is another telltale sign. When ducts have gaps or disconnected sections in the attic, the negative pressure on the return side pulls in fiberglass insulation particles, dust, and other debris. If you see dust puffing out when your system starts up, there’s likely a duct breach somewhere.
Our Approach to Duct Repair
We start with testing. A pressurized duct leakage test tells us exactly how much air your system is losing and gives us a baseline to measure improvement against. After testing, we visually inspect every accessible duct run, noting the condition of connections, insulation, and the duct material itself.
For systems that are structurally sound but leaky, mastic sealing at every joint recovers most of the lost performance. Mastic is a permanent sealant that doesn’t break down in attic heat like tape does.
For systems with damaged, sagging, or undersized ducts, we recommend partial or full replacement. We size new ductwork using Manual D calculations to match your equipment’s airflow requirements, and we fabricate metal duct components in our Abbeville sheet metal shop for runs where metal duct is the better choice.
Insulation Upgrades
Duct insulation in Kaplan’s climate isn’t a luxury. It’s a necessity. The temperature difference between conditioned air inside your ducts (55 to 60 degrees) and the attic surrounding them (140+ degrees in summer) is enormous. R-8 insulation is the Louisiana minimum for attic duct runs, but older homes frequently have R-4 or uninsulated ducts.
Upgrading duct insulation reduces the heat gain that warms your supply air and prevents condensation from forming on cold duct surfaces in the humid attic environment. Both improvements translate to lower energy bills and more consistent comfort.
