6 Tips for Good Ductwork Design

To make sure your ductwork is properly designed,
start by involving a knowledgeable HVAC design
professional early in your renovation design
process. These are some of the ductwork design
tips by HVAC professionals.

1. CHOOSE THE BEST LOCATION FOR HVAC EQUIPMENT
AND DUCTS.
With proper planning, the HVAC equipment should
be centrally located in the space to allow for
the shortest possible duct runs. Ducts should be
located in internal walls and ceilings to
minimize the loss of conditioned air. Avoid
installing ducts in attics and unconditioned
crawl spaces for maximum efficiency.

2. A DETAILED LOAD CALCULATION.
Especially when your space has different rooms or
areas with varying heating and cooling
requirements, its important that the load
calculations be done individually for each room,
rather than only for the space as a whole.

3. CONSIDER YOUR EQUIPMENT TYPE AND SUPPORTING
SYSTEMS
Certain types of air conditioning systems, like
heat pumps, require larger ducts. If your system
includes air purifiers with activated charcoal
filters, these also affect air flow and may
require larger ducts and/or additional air
returns.

4. USE THE RIGHT MATERIALS, FITTINGS AND
SUPPORTS.

Ductwork materials can vary depending on the
requirements and the budget, but make sure your
installer uses the right materials for your
needs. Flexible ducts (often called flex) made
from reinforced plastic are easier and cheaper to
install, but not as strong and durable as sheet
metal.

If quiet operation and energy efficiency of your
inverter split air conditioner are very important
to you, you might want to go with duct board,
made from pressed fiberglass, which is more
expensive but very quiet and efficient.

5. CHOOSE THE RIGHT DUCT SIZE AND LAYOUT

your HVAC design professional can determine the
most efficient ductwork design layout and
calculate the correct duct size. To account for
all the necessary factors, many professionals use
a tool called ACCA Manual D.
