Several things on my mind...... I had several techs look at the
(paid for several opinions). This is on a system in operation for
12 years....seemed to be working fine and then blew a breaker one day.
CY: Blown breakers, any of several reasons.
First team of techs said it was leaking "like a sieve" from the flare
by the metering valve. When they checked the freon, it was only a
low. So one would think "leaking like a sieve" means freon should
CY: yes, you'd think so.
But they quoted 375 head pressure and 55 low pressurre.
CY: We don't know what the temperatures were at the time he checked,
or if he told you the truth. But, if we make some WAG, here, the freon
may be a bit low, and the outdoor unit is in desperate need of
Estimated cost to repair leak and clean both coils was 650 - to 850
CY: How much to just clean the outdoor unit?
Second tech comes in, measures charge, looks at leak (doesn't use a
says "you have a leak, you're a little low on freon.....I will
overcharge the system a
little to so it will work until you have a chance to talk to our
estimated 1200. to correct the leak, another $500 to clean the
Total of $1800. Clear message "Buy a new system" He was very
in saying.."overcharging will kill the compressor" and " you will
have water damage
on floor" (low freon will cause evap coil to freeze).
CY: Sounds like he's pushing a new system.
Another tech suggested using a can of HVAC-R stop leak.
Three weeks later, system is still cooling fine. I am looking to
verify loss of freon.
One way or another, it's important to get this situation resolved.
CY: I can undersand you wanting to get some real answers. Sounds like
every time you get another estimate, you get two more answers.
With a new Bryant A/C running anywhere from 5 to 10 K (actual
quotes)....... it would be
important to me to see exactly how much of a leak is there and IF it
can be stopped by
a can of HVAC-R sealer which was recently recommended. Also knowing
how much of
a charge remains would be helpful to be able to discuss "solutions"
intelligently. Do I
have 6 months to replace the system or 6 days. Also, did cleaning
the coils actually
make a major difference in operating efficiency.
CY: Yep, it sure is nice to be able to have some time to work. Dirty
coils really kill the efficiency of a unit. Did it help yours, to have
em cleaned? Depends how dirty, and how good was the cleaning they did.
The members on this forum are a fantastic source of information and
it easier to become "knowledgeable" to solve minor problems,
maintenance maintenance and to make intelligent choics"
CY: I've really learned a lot on alt home repair.
