Home Improvement(dont trust the OT) Board.....A/C trouble

AC was serviced last year, found low 3 pounds of freon.
One year later it is 4 pounds low after it quit cooling well.
AC man says that a leak that slow is hard to get located and fixed, what does the OB say? Is that about right?

There is a dye that can be put into the system to find the leak. Could still be more difficult to find and fi than it is to juice it once a year though.

Probably the A coil. Basically they are pieces of crap that have copper tubing so thin you can almost see through it. If it has been leaking that long you should be able to see corrosion or the effects of the leak somewhere within the system. Most A coils have a 5 year warranty if it was a name brand unit.

Not sure, but I know a great AC man if you need a second opinion

It's probably leaking at the coils, that unit is most likely in your attic.

How much does it cost to replace a coil typically?

had one replaced about a year ago and it was about 2-2500 if i remember right. parts, labor

Damn, y'all smart.
It is the coil, 1465.00 to fix is the quote. It was corroded along with drip pan. Coil comes with pump for new freon, have to have r22 pump installed with new coil. The price includes that as well.
Unit was 11 years old, no warranty. Thanks for the replies.

1400 is a pretty good quote for replacing the coils. They are a pain in the arse to change

I thought it was fair, the are going to hopefully get it done Thursday

So until then is 1000 degrees in your house?

It's working fine. Just leaking thru pan into another catch pan. Freon charge has it nice and cold

Looks like some OBer's handled this with ease.

looked it up last night. i was charged 1800 for my replacement. you got a good deal.

I knew he got a good deal

I've been doing HVAC work for 36 years and have never heard of an evaporator coil that has a R22 pump on it, in it or any where near it. The fact is, there is no such of a damn thing as a R22 pump unless they are talking about the compressor... yes, I'm telling you that there is a large cloud of smoke being blown up your butt.
I would find a new A/C company ASAP.

I agree, I have never heard of an r22 pump.

ok,
I know nothing. Can you think of anything else that is specific to the type of freon that involves the coil. He specifically said that the new coil would have a pump/piston/thingamajig that needed to be converted to 22. I may have used the incorrect term.
Is there another part that would need to be freon type specific?
Thanks.
Remember, talk to me like a 7 year old.

I did a google search and came up with this:
An orifice (also referred to as a piston or flowrater) is installed in an evaporator coil when the coil is a different tonnage rating than the condenser or heat pump tonnage rating. Installation takes about 5 minutes, and consists of replacing orifice already inside coil. We have an online picture step-by-step guide which shows how to do this.
If you are installing a new evaporator coil and can not find manufacturer-specific information for your outdoor air conditioner or heat pump, use this chart as a reference to ensure a properly sized orifice is installed in your system.
R-22 R-410A
Tonnage Orifice Size Orifice Size
1.5 Ton 0.053 0.047
2 Ton 0.059 0.053
2.5 Ton 0.071 0.059
3 Ton 0.076 0.071
3.5 Ton 0.080 0.076
4 Ton 0.082 0.080
5 Ton 0.090 0.090
Now, I know for a fact he told me I was getting a 5 ton coil for a 5 ton compressor. He mentioned the two diff sizes needed because my system still runs 22. above it says that there are different orifice sizes for different refrigerants.
