comment Can the A/C temperature through a vent be significantly lower than in the air handler?
Assuming it's summer and the environment (i.e. your house, attic/crawlspace, etc) the ducts run through isn't colder, it's not plausible for air cooled by your evaporator coil to get even cooler as it travels to a vent. Most likely there are anomalies in how this is being measured. At the air handler, are you measuring temp after the coil? Are the air handler- and vent-site measurements being taken actually simultaneously, i.e. is it possible the system is changing states in between measurements, such as by turning on/off or changing load in the home?

I did this. It has been fine for about 3 years now. Thanks!

comment What is the best way to fill a hole in a concrete basement floor?
@Russell what looks corroded? There's corrosion on the pipe around the saddle, does that mean the contact between wire and pipe is poor?

comment How to properly seal/cover an unused chimney?
Update: we simply ignored this unused chimney for about a year. Then we decided to remove it completely. I hired roofers to remove the portion above the roof line and patch the roof. Then I removed it in the attic, two floor of living area, and basement. Lots of heavy lifting, but it enabled an improved layout of our kitchen/dining room!

comment Roof Decking: Plywood/OSB over skip sheathing (decking) or should I strip to the rafters?
I'm not an expert on this at all, but this article may be useful: askaroofer.com/skip-sheathing-roofing-in-roseville-95678. It suggests you should be fine to add OSB over the skip deck.

comment Do I need soffit vents and can I add them without taking the roof apart?
Is your "true attic area" actually connected to the soffits? I'm not sure if that's what you mean by "connected by about a foot depth of air space up the roof". Is that your rafter cavity? If so, then you could add soffit ventilation. As for whether you need it, your new metal roof may benefit from it if you get cold weather. Depends on how well your living space is insulated. If you have a cold winter and your space leaks warm moist air to the underside of a poorly-vented metal roof, moisture will condense on the cold metal - bad. If your insulation is really good that's not a concern.
