When upgrading your HVAC system, the focus is often on the new equipment—furnaces, air conditioners, or heat pumps. However, one crucial component that can make or break a system is often overlooked: ductwork.
An inadequate ductwork installation causes your system to work harder to properly cool/heat your home. This results in increased wear and tear on your system, potentially shortening its lifespan.
Air Quality Issues
Leaky ducts can allow dust, dirt and other contaminants to enter your home’s air supply. The ramifications of this are often poor indoor air quality and, in some cases, potential health issues.
The Importance of Manual D Calculations
So, how do you avoid over/under-sizing ductwork? Proper Manual D calculations.
Manual D is a method used to properly size and design ductwork for HVAC systems. This calculation considers factors such as the size of your home, the layout of your ductwork (current and/or future) as well as the capacity of your HVAC equipment,
Conducting a Manual D calculation ensures your ductwork is properly sized and designed to deliver the right amount of airflow to each area of your home.
Choosing a Qualified Contractor
A qualified contractor will conduct a Manual D calculation to ensure your ductwork is properly sized and designed for optimal performance.
We strongly advise against working with contractors who outsource the Manual D and/or Manual J process. Outsourcing these When these calculations risks miscommunication or lack of understanding between the contractor and the third party. This often results in poorly designed ductwork.
A reputable HVAC contractor should explain their system design/installation process and answer any questions you may have.
Properly designed and installed ductwork is essential for the efficient operation of your HVAC system. Understanding the role of ductwork and the importance of Manual D calculations, can help you avoid costly mistakes and ensure that your new HVAC system provides reliable comfort and energy efficiency for years to come.
