Excessive air in well pump water system?

I have a vacation home in the Catskills, NY with a very deep well 250" well. The system is a submersible well pump with a well tank with no bladder. Inside the house I have two air valves one locate just as the water line enters the house at the check valve before the tank and another valve located on the side of the tank.
The problem is when we use the system for 3-4 day we get excessive amounts of air it the system. When we open the faucet air jets out of the system for 30-45 seconds and we just leave the faqucets open until all of the air is gone. We have to do this for both the hot and cold water?
I once was going to put a valve cap over the air valve before the tank on the check valve but was told by a neighbor not to since this lets air back into the system so the well pump line does not freeze during the winter?
Any suggestion to how to get rid of the air?

The air valve on the side of the tank needs to be replaced.
Don't try to fix the old one. Its just better to get a new on.
Some times, if you try and fix the old one. It will start to leek water. Because there is a rubber seal inside that will break if it is taken apart.
Turn the power off to the well.
Drain all the pressure off, take the gage out(if it has one there) Drain all the water out before putting the new one in.
Unscrew the air valve out. Put the new one back, and turn it all back on.

No, Do not put a cap on the little air inlet on the check valve. It is there to break the vacuum, and drain the top joint of pipe, when the pump cuts off.
When the pump comes back on, it pushes that air back in to the tank. That is where the air cushion that gives you the pressure comes from.
