Did I really need freeon?
It's been a while since my last post. I had some trouble with my previous account (amaretto) since I changed email addresses and decided to just register a new one.
A couple of weeks ago, I made a call to an Air Conditioning service to inspect my vents and do maintenance work on my AC. $3000 later, my AC is working fine, but... no, I didn't have both units replaced, so, if you're scratching your heads and thinking that charge sounds a bit excessive, you're probably right.
When they came to service my AC, the charges immediately began to rake up. One of which was the addition of freon.
This came across to me as odd, since the repairman had specifically told me that I did not have a leak (and that because of that I would be able to afford other repairs... but that's another story).
I consulted a technician who told me that if the AC did not have a leak, which would be clearly indicated by ice formations, then I did not need freon because ACs were sealed units.
Can anyone verify this?
