It should not take more than 15 min to 30 min to replace a wax ring so the work order is accurate especially if they caulked the base for a more finished look. If it is an apartment complex, they did the work, because without a new wax ring your stool will leak through the floor and down into what ever is below. We are not talking about clean fresh water, we are talking about what you are flushing . It will damage the wood and weaken and rot the framing etc... so they wouldn't cheat you on that one, it would be way more costly to them if they did.
I don't know when you are hearing air brakes. When you flush it, or when the tank is filling up? If it's when the tank is filling up it could be several things. Air as I mentioned early if it is air in the line it will eventually fix itself, or the pipes that the water flows through are different sizes and the pressure is very strong by the time it reaches your toilet line which is usually 3/8 inch if the copper pipe is 1/2 in and flows into the smaller one and the water pressure in your apartment is relatively strong it will cause that sound, and even seem to shake the toilet a little. Which may have caused the wax ring to unseat itself to begin with, hard to say without seeing it for myself. You can check and make sure the shut off valve is fully opened, then turn the water on in your kitchen then turn it on in a few more places like the tub and shower, wait a few sec and while everything is running flush the toilet, the water pressure should be lessened by the running water and so you won't hear the air brakes or at least the sound will be reduced. If that is the case then, really you just have real good water pressure. Which is better than barely having water pressure. Or if that test fails to give you an answer, it might be the type of float in the tank. It could be the needle and seat that move up and down inside the floation device are crusted in lime deposits , and a new float will fix the problem anyway hope that helped.

Wow, that's a lot of information. Thank you so very much. I really appreciate this and will try running the water. The air sound is every couple of hours or so.
