But there's bargains to be had.
My ten-year-old Trane bellied up and washed ashore during hurricane Yikes.
My son has a neighbor (Guatemalan if that makes any difference) who
moonlights off the books. Being in the business, he found a two-year old
condensing unit, brought it over at 8:00 p.m., installed the unit (including
brazing a couple of joints), evacuated (I guess sort of) the system, and
recharged it. He was done by 10:00 p.m. and I was out $700.
Been working swell these two years.
It might pay to, um, "inquire" around. (I'm in Houston if you want my tech's
Man, at least this one, should always have one cup of coffee before posting
You can still buy replacement evap coils. It is the condenser units you
can not buy.
Sounds like the OP won the lottery if that is the only leak in the system.
I have experienced to evap coil failures on two 1995 systems about 2 years
Also replaced the evap coil in my 1996 Nissan twice now. I am of the
opinion that the evap coil making process has gone way downhill in the last

It could be something as simple as leaking valve cores in the
Schrader service valves. I've seen leaks develop years later
because the valve cores were not tightened at the factory or
the installation tech didn't tighten the cores enough when
reinstalling them. Tiny leaks can be handled by a product I've
had good luck with manufactured by Cliplight called SUPER SEAL HVACR.
It's a stop leak for AC systems.
Many techs don't know how to properly use them and like most folks
are afraid of something different. I most definitely don't push
sealers as a cure all and prefer brazing up a hole in a system but
some tiny leaks respond very well to the sealer I've used. I'm also
fond of UV florescent dye for finding tiny leaks. I've used it to
find pinhole sized leaks in many refrigeration and AC systems.
I can find most leaks with the Mark 1 Eyeball and E240/ns64 Ear. I
have not only the UV dye but ultrasonic leak detectors and sniffers.
Another item I use is dry nitrogen. I will break down an exasperating
system into zones, seal them off, pressurize them and look for a
pressure drop. When me and my buddy install an AC system in a house
that won't be occupied for a while, we don't install the condenser
but pressurize the line set connected to the evaporator with N2 and
leave it. If the pressure drops or vanishes a week later, we know a
carpenter put a nail through the line set.
The way I hear it:
Leaks big enough to find with "sniffers" and fluorescent/"UV" leak
detection are worth fixing in ways that target them - brazing or whatever
along those lines.
Leaks smaller than that appear to me to deserve Cliplight's "Super
Keep in mind that Cliplight sells not only "Super Seal", but also
dyes, dye injectors, lights, and kits for fluorescent/"UV" leak detection.
As a result, it appears to me that Cliplight has a reasonable rate of
marketing their "Super Seal" for usage when that is appropriate. That is
heavily-in-my-mind because they also sell means to find leaks worth fixing
more directly than with application of their "Super Seal".
And I have yet to hear of Cliplight selling braze, torches, torch
hoses, torch fuel or oxygen or tanks thereof, although they do sell the
most convenient and durable torch ignitor that I ever saw ("SparkKey" IIRC,
and I have one.) But as much as they sell leak detection dyes, lights,
and dye injectors as well as torch ignitors, I seem to think that they
want their customers to target leaks worth finding and brazing or otherwise
repairing without their "Super Seal" when such leaks are big enough to
be worth repairing more directly than with usage of their "Super Seal".
And that they promote usage of their "Super Seal" mainly to plug smaller
leaks that are too small to be worth individually both detecting and
repairing by leak-site-specific means.
