Hi Home Repair Gurus..

Is it normal for an brand new AC unit (installed in a newly built home) to
require replacing about half the freeon (say about 2 pounds worth) after
about 6 years..

My AC recently stopped blowing cool air (even though the fan is on), even
after replacing the filter, and the AC tech said that there was some freezing
that had occurred due to a lack of freon, and that it had to be replaced..

Thanks



This is Turtle.

if half the freon was missing from the system in 6 years of operation. well
you have a leak that let it out over that 6 years and you need to have the
leak found and repaired. If you go for just refilling it and let it go. well
you just became what is called a cash cow in the HVAC business for you will
always want the serviuce man back to refill it every years or two.

Also if you think you should change your freon in your system every so often,
well it is recommended to change the freon out in your hvac system every 164
years.

And not a day longer.

BTW, it's possible that the refrigerant leaked out over a 2 day period, we
don't know now do we?

i have a Son in law that was working for Dupont at the time and he and I was
talking to one of there chemical engineers at a social gathering and he was
telling the R-22 did show some signs of some break down on or about 164 years.
They have ways of projecting time of freon break down and r-22 does break down a
little at 164 years. He did say that if it would be the case. You should change
out the R-22 every 164 years in any equipment that you may have.

So we should recommend changing the Freon 22 out every 164 years !
