Low-load homes can be pretty tricky to figure out, especially when it comes to equipment sizing and duct design.

Simply put, we have less room for error and must be very precise in our load calculations and equipment selections. There are fewer places to hide when we design ductwork for low-load homes, so we need to be diligent and refer to ACCA Manual T for best results.

Ed Janowiak recently joined me on the HVAC School podcast to talk all about Manual T and why it matters, especially in low-load homes. You can listen to that podcast on our website at https://buff.ly/3QUCKSb or on your preferred podcast app.
