I spend more time in this thread than I can reasonably afford but it is my passion. I read all of the post about HVAC some I reply to and some I don’t. I don’t want to be classified as a know it all but I have come to the conclusion by reading these post that the average HI knows very little about what he is looking at. Some say well it is just a visual inspection and that is true but if one understands what he is looking at very easy to spot deficiency. You don’t need a bunch of tools you just need some knowledge.
I inspected a home this week that made me sick and I felt sorry for the sellers for being duped by some contractor that was grabbing the money and running. The duct work in the attic was just barely a month old revision from a downflow that had water in the ducts.I have the exact statement below in bold print that I copied and pasted directly from the report into this post. I don’t very often make this kind of call on a home but I was unable to keep from being very vocal. Read the statement and tell me if you would have the stones to make this kind of call.
C. There are supply air registers within the home with absolute no air flow as indicated with a
meter. In my opinion the updated supply air ducts meets no qualifications for residential
applications. The installer has used starting collars tapped onto the ridged trunk line with the
concept that static pressure will provide air flow. This does not happen with the size and or speed of
the blower. Static pressure duct systems are normally used in conjunction with high speed/volume
blowers in commercial applications. Recommend the installing contractor revise this duct system to
provide equal air distribution through out the home at his cost.
