Crowley’s Older Homes and Their Duct Systems
Crowley has a lot of character in its housing stock. The homes along North Parkerson Avenue, around the historic downtown district, and through the established neighborhoods near Crowley High School were built in an era when ductwork design didn’t receive the engineering attention it gets today. Many of these systems were installed when central air was first added to homes that originally relied on window units or no cooling at all.
Those early duct installations were often improvised. Contractors worked with the space they had, running ducts through interior walls, above dropped ceilings, or through crawlspaces that were never intended for HVAC distribution. The result is duct systems with sharp turns, inconsistent sizing, and joints that have been leaking conditioned air for decades.
What Poor Ductwork Does to Your Energy Bills
When 20 to 30 percent of your conditioned air leaks into unconditioned spaces before reaching your rooms, your HVAC equipment has to run longer to compensate. In Acadia Parish, where the cooling season stretches from early spring into late fall, those extra run hours translate directly into higher electricity bills.
But the financial hit goes beyond just wasted energy. Your equipment wears out faster when it runs more cycles. Compressors, blower motors, and capacitors all have finite lifespans measured in operating hours. A duct system that forces your AC to run 30 percent longer effectively ages your equipment 30 percent faster.
Duct Leakage Testing and Sealing
We don’t guess at whether your ducts are leaking. Our technicians use calibrated duct leakage testing equipment that pressurizes your system and measures exactly how much air escapes. This pinpoints the severity of the problem and tells us where to focus repair efforts.
Mastic sealing is the professional standard for duct joints. Unlike duct tape (which dries out and peels within a couple of years in a hot attic), mastic is a thick paste that cures to a permanent flexible seal. We apply it to every accessible joint, seam, and connection point. For larger gaps, we bridge the opening with fiberglass mesh tape before applying mastic over it.
After sealing, we retest to confirm the improvement. In homes with significant duct leakage, the before-and-after difference in measured air loss is dramatic, and homeowners notice the change in their comfort and their energy bills.
Duct Insulation in Acadia Parish
If your ductwork runs through the attic (as it does in most Crowley homes with slab foundations), insulation is critical. Summer attic temperatures in Acadia Parish routinely exceed 140 degrees. Uninsulated or poorly insulated ducts allow that extreme heat to transfer into the conditioned air flowing inside, which means warmer air at your registers and longer system run times.
Louisiana requires R-8 minimum insulation on attic duct runs. Homes built before that standard was enforced often have R-4 or even bare metal ductwork in the attic. Upgrading the insulation on your existing ducts is one of the most cost-effective improvements you can make to your HVAC system’s efficiency.
We also check for condensation damage. When cold duct surfaces meet hot, humid attic air without adequate insulation between them, water condenses on the duct exterior. That moisture drips onto ceiling drywall, soaks into attic insulation, and can promote mold growth.
Custom Fabrication for Crowley Homes
When repair or sealing isn’t enough and your ductwork needs replacement, we build custom metal duct components in our Abbeville sheet metal shop. Metal duct outlasts flex duct, handles airflow more efficiently, and holds up to the extreme temperature swings in Louisiana attics. Every piece is sized and shaped for your home’s specific layout using Manual D calculations that match duct dimensions to your equipment’s airflow requirements.
Get Your Ducts Evaluated
If your Crowley home has rooms that stay warm no matter what you set the thermostat to, or if dust seems to blow from your vents when the system kicks on, your ductwork is worth investigating. Call F & R Air Conditioning at (337) 893-5646 to schedule a duct evaluation.
