Ducting

This information comes from years of experience troubleshooting HVAC systems in homes and businesses. If your equipment needs replacing every 7 to 10 years and your blower motor fails every two years, poor installation or unresolved issues are likely the root cause. Homes built before 1969 typically weren’t designed for central air conditioning, which requires moving more air at a higher velocity than heating. Redesigning ductwork can often cost more than new HVAC units.

Think of the furnace or air handler as the system's "heart," containing the control board and blower for heating and cooling. Ductwork acts as the "arms and legs" of the system; inadequate duct size can restrict airflow and stress the furnace. Poor circulatory design affects occupant comfort.

When technicians inquire about a home's old system, they are assess whether the ductwork meets client expectations, as it's often hidden. Adding an addition to a home without considering HVAC impacts—like cutting duct holes or blocking vents with flooring—can lead to significant problems.

Modern builders prioritize comfort and energy efficiency, using calculations from engineers for duct sizing and airflow. Most new homes include manual dampers for seasonal adjustments. Remember, air behaves like water—it can flow smoothly or create turbulence based on duct design. The goal is to circulate air effectively throughout the space.
