Ductwork
Built to Match the System It Serves
Ductwork installation in Sherwood for new HVAC systems and retrofits where existing duct layout is causing efficiency loss
Poor ductwork is the single most common reason a correctly sized HVAC system underperforms—and in Central Arkansas's mixed housing stock, where homes range from postwar construction to recent builds with varying duct configurations, that problem shows up more often than most property owners expect. A Squared Heating and Air designs and installs ductwork for both new systems and retrofit applications across Sherwood, Conway, Russellville, and Pine Bluff. The process begins with a duct sizing calculation based on system load, not on the footprint of the existing duct layout, which means the installed ductwork is matched to the equipment rather than the other way around.
Duct sizing that doesn't align with system output creates static pressure problems—the system has to work harder to move the required airflow, which increases energy consumption and accelerates wear on blower motors and compressors. A Squared identifies duct loss during the load calculation phase, before installation begins, so that the new system isn't undersized to compensate for a duct layout that should have been corrected. Duct sealing is completed using mastic or appropriate tape at all joints, and supply and return plenum balancing is evaluated so that airflow distribution reflects actual room loads rather than what was convenient to route during the original construction.
Arrange a duct assessment to determine whether your current layout can support a new system or requires modification before installation.
What You Notice Once Ductwork Is Correctly Installed
Ductwork installation involves calculating required airflow for each zone, routing supply and return runs to minimize resistance, sealing all connections with mastic or rated tape, and verifying static pressure after installation to confirm the system is operating within the design range. Static pressure testing post-installation is not a formality—it confirms that the installed duct system actually delivers what the load calculation predicted, and it catches installation errors before they become long-term performance problems.
After a properly sized and sealed duct system is in place, rooms that previously ran several degrees off the thermostat setting begin to hold temperature consistently. You'll also notice that the system reaches set temperature faster and shuts off at normal intervals rather than running for extended periods trying to compensate for conditioned air that was escaping into unconditioned space through unsealed joints.
The scope of ductwork installation varies depending on whether the project involves a new construction layout, a full replacement of deteriorated existing ductwork, or a targeted retrofit to correct specific high-loss sections. A Squared Heating and Air works alongside heat pump installations and standalone duct projects, and the approach for each is determined by what the load calculation and static pressure testing actually show—not by a standard package applied regardless of building conditions.
Questions Before Starting Your Ductwork Project
Property owners in Sherwood and surrounding Central Arkansas communities often have specific questions about whether their existing ductwork can be salvaged or needs to be replaced before a new system goes in.
How is duct sizing determined for a new installation?
Duct sizing is calculated based on the total system load and the airflow required for each room or zone—this calculation accounts for the length of each duct run, the number of fittings, and the static pressure budget available to the system before blower capacity is exceeded.
What does static pressure testing show after installation is complete?
Post-installation static pressure testing measures actual resistance in the completed duct system and confirms that the installed layout matches the design parameters—if pressure readings fall outside acceptable range, specific sections are identified and corrected before the system is commissioned.
Why does duct sealing matter if the joints look tight?
Duct connections that appear visually secure can still leak at joints and seams, particularly in older Central Arkansas homes where flex duct connections have loosened over time—mastic or rated tape creates a durable seal that tape alone, especially standard duct tape, does not maintain under temperature cycling.
When does a new HVAC system require new ductwork?
A new system requires duct evaluation and often modification when existing ductwork is undersized for the new equipment's airflow requirements, when static pressure testing reveals excessive leakage, or when the current layout lacks adequate return air pathways for the system to operate efficiently.
What is plenum balancing and why does it affect comfort?
Supply and return plenum balancing adjusts how airflow is distributed across different zones of the building so that no single area receives a disproportionate share of conditioned air—without balancing, rooms farthest from the air handler often stay uncomfortable regardless of how well the equipment itself performs.
A Squared Heating and Air approaches ductwork as an integrated part of the overall HVAC system rather than a separate trade, which means duct decisions are informed by the same load data used to size the equipment.
