initial symptom is freezing pipe leading to outside unit.
gauged pressure and was at 75 which is good.
register is blowing around 60 deg. but was told pipe freezing means coils is freezing too.
i have a attic trane system and was quoted $700(that was the cheapest i found) to just clean it since they said the unit was upside down/hard to get to.
id rather brake it and then have it replaced before i just dished the $$ out.
i just need detailed info on what needs to be done from A to Z
i know i need to properly dispose of r22 in system and then remove coil but do i just cut the lines and then do new welds/solders?
proceed to cleaning with what?
put back together and just use torch to solder llines back?
vacuum system?
then what?
is there a particular sequence for charging? and on high or low side?
thanksin advance for your help

You cannot handle refrigerant at all without being EPA certified. Then you have to properly recover the refrigerant before proceeding. It's over $12,000 fine and up to 5 years in the pen for letting refrigerant into the atmosphere knowingly.
I would get a 2nd opinion of the problem. How old is the system? $700 bucks is about right to remove the coil for cleaning but if it's an older system the $700 bucks may be better spent on a new one.

There is a good chance you would be able to clean the coil without removing it. All it may take is a brush and a vacuum.
Get out your tools and a trouble light and start taking panels off to get at the coil.
Let us know what you find.

the system is a trane and is 10 years old. judging from the original owners, id have to say the coils never been cleaned.
i didnt realize the penalties so i will have a pro do the pro work and i do what i am allowed.
as far as the unit it is a 10 year old trane and i think its a XE series but i will look when i get home.
i will also start off by tearing all the panel off to see if i can get to it w/out taking the coil out.
can i rig something with the panels next time so i dont have to take it all apart next time?
i dont think it has a panel for each side. it looks like a whole case but ill double check when i go home today.
thanks for all the feedback and might anyone have a layuot of the XE series units? id like to see the unit from the inside on paper.

If this is the unit you have in your attic in a horizontal configuration, the coil will be in the ductwork.
You will need a good selection of tools and maybe a set of tin snips if they didn't care about servicing when installed.
Mind you, maybe you will get lucky and have a cased coil which only has a few screws to remove.
