hvacvent
I'm going to add some crown moulding to some bedrooms. I've got HVAC vents mounted near the top of the wall and the moulding will cover part of the vent.
I want to move the vents out of the way. I can't move them down and am thinking of moving them to the ceilings instead (there's an attic above them so I've got reasonable access). Is there any reason this is a bad plan? Do they work just as well in either location?
I'm really happy with my Honeywell wireless thermostat. Battery lasts a very long time and it works through 4 floors. A quick Google search shows several options below $100... Something like this for $65 perhaps? Not the one I have though and not sure if it includes the receiver.
Your inspector is correct. Air should enter at the soffit, and exit at either roof vents or a ridge vent. With the current setup air could be entering either the soffit vents or the roof vents, and exiting either the roof vents or the ridge vent. Since your soffits are covered with insulation (because there are no baffles), I'd guess that air is entering the roof vents and exiting the ridge vent. This means only the air near the top of the roof is cycling, which can lead to problems with the roof including a shortened roof life.
In my house there were originally roof vents in the roof above my garage. When they did a reroof they switched to a ridge vent, and as you can see they covered over the old roof vent openings.
On a side note: Inspectors are hired by you, and work for you. They have no reason to lie or mislead you, since they will not gain in any way from it. In fact, you can probably trust an inspector more than a random person on the internet. Seeing how you paid the inspector for advice, while I'm doing this for free.

I think part of this depends on where you live, and whether this is primarily a cooling or a heating issue. I'll assume we are talking the high velocity vents, which are easy enough to move around. (A check of your profile says San Jose, so I also assume this is a cooling issue.)
Wall mounted vents used for cooling will push cool air across the ceiling, mixing with the warmer air up there. The cool air will now gradually settle down, because cool air is denser than warm air. What you won't feel so much is moving air.
Ceiling mounted vents, because they push the air DOWN, not horizontally, will arguably create more drafts in the volume that you actually inhabit. This is something my wife would not want. So if you do put them in the ceiling, place them where you will not feel the drafts.
