Kinky are you? Flex duct inspections

Kinky are you? Flex duct inspections Chelan Home Inspection Services

So kinky may be a relative term. One person’s kinkiness may be another person’s normal. I am not the one to judge.

But there are appropriate times for your kinkiness, kinky are you?

                                        

When I am doing a home inspection I try to get a feel for how the HVAC system is performing. Do I have areas in the home that seem to have little to no air flow at the register. I make a mental note so when I am doing the flex duct inspection that I can look for any issues that may explain the lack of performance at a register.

Here we have a kinky little detail.

                               

Duct installation should be performed in a manner to provide good air flow. Air is a fluid and as such is affected by friction, bends and restrictions like water.

The performance of your heating and cooling system will be greatly affected by a poor installation.

                                                         

The bend radius at the center line of ducts should be equal to or greater than one duct diameter. The duct should not bend across a sharp corner of building materials such as joists or truss supports. Sharper bends increase pressure drop significantly and reduce airflow.
If a flexible duct is not fully extended, the friction rate increases proportionally with the compression. Care needs to be taken to minimize sagging or snaking of the duct between supports and minimize pressure loss.

              

Your systems performance will be dictated by many things but your ducts have one of the greatest influences on the system.
