Does Freon or refrigerant deteriorate over the years? My coworker told me that it does. I’ve never heard of that.

Does Freon or refrigerant deteriorate?

As a general rule no. If you have a good refrigeration man and he cares about your system and takes care to remove all moisture and air from it. Most refrigerants are very stable if there are no other elements in your system.

Compressor failure/burnout does cause it to deteriorate and need to be replaced. Any flame/arc around the refrigerant will change the properties of the freon and can cause it to become poisonous. Unless something like that has happened or water/air gotten in system, it should not need to be replaced. The intrusion of water into the system is over rated as installing even the smallest pickle dryer (size of thumb) will hold 100 drops of water, so any time you changed the dryer there should never be a problem with water. The newer refrigerants are a lot more sensitive than the R12 that I replaced more than 2,000 compressors and never worried about vacuum pumps etc. (This was before recovery was required.)
The old "Payne" central A/C unit that was attached to my house was 39 years old when I had it replaced with a new heat/AC system. I turned it off when the contractor pulled up in my driveway the morning they came to install the new system..... 39 years old, and it was still running, and still cooling the house with the original R22 refrigerant that was put in when it was new.
(in fact that old R22 unit blew colder air than my new AC with R-410a)

I heard that alot from customers during my years as a tech.The old "Payne" central A/C unit that was attached to my house was 39 years old when I had it replaced with a new heat/AC system.

Could have been subjective, but with the newer 410a systems, they ran at a higher evap temperature than older ones. R22 coils typically operated at around 40 deg (approx. 70 psi) at design conditions. The newer R410 units operated at 50 deg coils (approx. 140 psi). Being higher latent (i.e moisture) removal designs, the air temp off the coil was not as cold. It was dryer air (which added significant efficiency - which was how the companies met the ever higher SEER rating requirements), but it wasn't as "cold". And people noticed. Had lots of complaints form folks who shelled out big bucks for a new system and it didn't feel as cold. I told them to call the installing contractor and see what they could do.

Just wait new refrigerate is coming for comfort cooling Jan 1 2025. R -454B is what Bosch and some other manufacturers are going to use it for 410A alternative.
