Ductwork Service for Sunset Homes
Sunset is a small community, and homeowners here don’t always have convenient access to HVAC contractors who specialize in ductwork. Many local companies handle equipment installation and repair but overlook the duct system that connects everything together. That’s a missed opportunity, because ductwork problems are responsible for a surprising share of comfort complaints and high energy bills.
F & R Air Conditioning travels to Sunset regularly for HVAC service calls, and ductwork evaluation is a standard part of what we offer. We’ve seen enough duct systems in St. Landry Parish homes to know that the combination of older construction and Louisiana’s extreme climate creates conditions where duct problems are common.
Why Ducts Fail in This Climate
Louisiana’s cooling season runs roughly eight to nine months. During that time, your ducts cycle between carrying 55-degree air and baking in an attic that exceeds 140 degrees. That constant temperature stress breaks down connections, degrades insulation, and causes materials to expand and contract in ways they weren’t always designed to handle.
Flex duct is particularly vulnerable. The tape or clamp connections at joints loosen as the duct material expands and contracts daily. The outer jacket becomes brittle with heat exposure. Support straps compress the insulation, reducing its R-value at those points. Over 10 to 15 years, a flex duct system that was adequately installed can deteriorate to the point where it’s losing 25 to 30 percent of conditioned air.
Metal duct holds up better physically, but connections still develop leaks. Sheet metal screws leave small holes that add up across a system. Joints sealed with old-style tape have long since opened. Even a metal duct system benefits from professional sealing every couple of decades.
What a Duct Evaluation Includes
When we evaluate ductwork in a Sunset home, we combine testing with visual inspection to get the full picture.
The pressurized duct leakage test measures total air loss across your system. We seal off your registers, pressurize the ducts through the air handler, and measure escaping air. This gives us an exact number, not an estimate, that tells us how much conditioned air never reaches your rooms.
The visual inspection covers every accessible duct run. We check for disconnected or damaged sections, sagging flex duct, crushed runs, inadequate insulation, moisture damage, and signs of pest intrusion. In Sunset homes with crawlspace ductwork, we also look for moisture-related damage on the duct exterior and hangers.
Repair, Seal, or Replace
Based on what the testing and inspection reveal, we recommend the most appropriate solution.
For duct systems that are properly sized and routed but have leaky connections, mastic sealing recovers most of the lost efficiency. Mastic bonds permanently and doesn’t degrade in attic heat the way tape does.
When insulation has deteriorated below the R-8 minimum required for Louisiana attic duct runs, we upgrade it. Proper insulation prevents heat gain from the attic and stops condensation from forming on cold duct surfaces.
If the ductwork is beyond repair, whether due to extensive damage, incorrect sizing, or advanced deterioration, we design and install a replacement system. We fabricate custom metal duct components in our sheet metal shop and size everything to match your equipment using Manual D calculations.
