If you have too much air you must have the extra check and Schrader valve. It maybe in the well below the well seal. Some people do it that way. Either way an AVC will solve the air problem.

I have read that the combination bleeder/snifter in the pipes themselves suck in air for this kind of configuration; not down at the pump itself.
So, based on what I've read and Craigpump's comments, I don't think this statement holds water - "the only way air could enter the system is through the pump intake."
Correct.It is my understanding that a Schrader valve is one that looks like a bicycle pump valve.
Bladder tanks have them but so too do snifters.Everything I've read says that Schrader valves go with bladder tanks.
Hydro-pneumatic tanks like yours require airmakers which in turn require a checkvalve above the static water height. These are often near the tank but sometimes they are at the top inside the casing.I have also read on this forum in the training blogs that one guy said that having a check valve above ground was a bad idea.
Yes, you are wrong and you have much more reading/learning to do.And yes I coud be totally wrong. Maybe we need others to chime in and answer this question.
Correct.

We don't need any others to chime in here. Valveman is an expert in the field and others have chimed in with their expert advice. You just need to start digesting it.
There is no snifter.
In some areas it is not uncommon to install 2 bleeders in the drop pipe so that a measured amount of water can drain out. The air in this section of pipe will charge the tank every time the pump cycles. A float-style air volume control valve screws into the mid-section of the tank, and allows excessive air to escape when needed.
I don't think I have a check valve there either.
I think the only check valve I have is at the pump itself.

...Sorry for the rant. It's just I get soooo tired of dishonest people.
I don't want to get mired down in semantics about whether or not there is a snifter. A snifter valve may take many forms. Essentially, it is a one-way valve that lets in air but seals on pressure. If there are two bleeders in the drop pipe, the top one acts as a snifter.
Regardless, of what physical form this valve is in, a topside checkvalve closes, the bleeder opens, a vacuum is formed, and air is sucked through the snifter into the pipe when gravity causes the water column to fall. Then, when the pump starts, the bleeder and the snifter both close, the air gets compressed, the checkvalve opens, and the slug of air goes into the tank.
Bottom line... the AVC is not working.
I also want to understand the architecture of it
and whether my Well guy was trying to rip me off.
There is no sure way to know the answer as your well guy might simply not have experience with all of the possible configurations.
I would also like to know the architecture of your system. But without pulling it up and seeing if and where the bleeder/bleeders/drilled hole, or leak is, we are just guessing. The only thing we know for sure is that you are getting air in the lines, so your AVC must not be working.
Yes that is the check valve under the pressure switch. And your Schrader/snifter/ or hole in the pipe that lets in the air, must be on the pump side of that check valve.

I really do understand what you are going through. Where I live in this small town, my choices are even more limited. Dare to challenge the wisdom of the Pros without scruples, and you quickly gain a bad reputation, the result of which they won't serve you even if you beg. I've been forced to either DIY or do without.
This is awkward, but...
