Great job Tim! The only thing that seems outta whack with the guided workflow would be that I feel it should guide you to capture indoor power measurements during that part of the test, especially in furnace country where often times that step requires removing a panel that shuts the unit down.
Great observation. I think thats because we dont actually turn power on and start testing until after the condenser workflow. Masters like yourself probably have their own flow. This is for newbies. I prefer their order myself.
Great Video !! Where you entered the line set length you put “23’ because I bought a 25’ line set and had 2’ left over”. Isn’t it asking for “equivalent” lineset length? Meaning you should add 6’ for the liquid line drier and some additional feet for however many elbows you had?
Tesp is surely way off, makes me wonder what mq is actually using it for, just to tell you if youre over your target it seems,which we can figure that out on our own. In your case here, you need to test your return static downstream of the filter, if you had, youd see your return static more like around .2 with that filter give or take a tiny bit. As for the supply, you didnt show what your system looks like but .04 doesnt seem correct either, can you not drill a hole immediately downstream of the coil? Even in the cabinet is a good spot rite after the coil, put plug in after and your setup to easily test in future without peeling back insulation on duct. You can even take out a screw in cabinet and use that hole then put screw back in. I use basketball pump needle in these cases and works very accurately. Im curious to know how your new results plotted on your fan curve would compare to the 660cfm mq has you at.
My TESP is so low because I desiged my ducts for 1000 CFN which is what my load calc told me. But my house ended up performing so well, I backed the blower down to 700 CFM. After this video, I closed off some dampers to balance flow room to room and my TESP is now 0.2". MQ will compare baselined TESP to further tests and alert you when it changes, even if the new TESP is still considered low.

Tim, this was an outstanding video. I too love the new workflows! #gamechanger
😊
Great video! Thanks for posting
Youre welcome
Great info. Done well. Thank you.
5" thick filter?! 👏
Great video.l have all of those tools. IT just takes a lot of time😊
Like anything if you set up the process and repeat it, it takes less time. I can do a full checkout in 20 minutes.

I've never done it that way. Do you have a link to a reference?
Equivalent length is only going to be a factor when sizing lines. Don't think mq cares about that for this purpose,
