"Cheapest way is 1/50 HP ceiling fans put on low this will give up to 10,000 CFM movement. If the HVAC system has a ECM motor and on low low about 200 FPM will cost just $200 yr in power with high end UV light and electronic air cleaner."

Who among us tracks the accuracy of Manual J?

I have hour meters on maybe 20 systems now.    I like to see the run time when it's "4" degrees in Kansas City.  99% rate in KC is +4' degrees.  My goal at 4' is 100% run time.   I have a super sealed home 2,100 square feet  with a 2 ton ground type heat pump R-30 walls, R-60 attic, R-8 windows & doors with 98% run time @ "+ 4' ".  When the strip heat turned on, it smelled up the home with the dirt  off the 5 KW strip, heat…

This is using still and moving camera,   Then gets stitched with software.     Tell me what you think?   On the photo that move you slow it or speed it up or go all the way around.   
Google give big points with using it.   Some say more than video.

Eric,

My client has 2 very different ManJ reports from 2 HVAC distributors. What would you charge for a full design with including ducts? It will be about 8 zones with air source heat pump and 50% radiant.

Thanks,

BobZockoff
