Sally I typically work on commercial and residential ac systems up to
30 years old that have never leaked a measuarable amount of freon.

Ask your friends and neighbors how often they replace their coils.

They SHOULD last 20 years, but do they always?
No.
Carrier had a rash of bad coils in the 90's. I'm replacing one today, only
9 years old.
Your tech should be able to narrow things down for you as to roughly, if
not specifically, where the leak is.
He should be able to ascertain whether or not the coil is dirty by
measuring the air flow across it.
As for the cost to replace it, it's fairly labour intensive if done
correctly, and coils aren't cheap.
Go with someone you trust, not necessarily the cheapest guy.

They only last 5-7 years when they were incorrectly installed in the first
place. And without seeing the installation, there is no way I can even guess
as to what a reasonable cost is.

The part will cost him about $300.

The labor will likely take less than a full day.

The AC trade considers $1500/day profit reasonable. They whine about how
much it costs to run a pickup truck and pay some high-school graduate ...
as if you didn't need transportation to get to your $20/hour job.

This is what you get by allowing politicians to license tradesmen and
legalize the restraint of trade.

Poor Richard. It sounds like you got fucked real hard by a serviceman
because you were too stupid to change your own dirty filter. Life must
suck to be you.

Sally, I have seen many many many coils now lasting only 2, 3 , 5
years and then leaking. Sad but true. Ive replaced 3 so far this week.
If your system is 30 years old you probably dont know what a leaky
coil is. The older ones were made differently. Check out the weight of
the older ones versus the new ones and you will understand. Your coil
could very well be leaking. It could also be several other things.
Electronic leak checking just isnt hard. If you dont like the opinion
you got, get another.
Now, how about posting that pic of your tits.
Bubba
