Then we replace the filter drier, then pull a good vacuum to remove all air from system, and then we recharge to system specs using either superheat, or charging cylinder, or scale. We think flare nuts need to be abandoned all the way, but today many commercial refrigeration applications still use them. Me and my partner are self taught, and have seen so many cheap systems in the field, so if we can repair a unit it's better than replacing it with a cheap one. Our business is pride services.
It Has another Problem if u Look at it Closely , Where the Refrigerant enters the Evaporator the Copper tubing is Bent Over Closing it Off Mostly. The Suction pressure is not high enough Because it Can't Get Enough Refrigerant.Leading to Coil Freeze ups and a Very Low Suction Pressure.and Some Real Weird Pressure Control Settings.Not a Pump Down System.
i would just tighten that nut as long as there was still pressure in the system, u could just recharge it and be outta there in minutes and hopefully not back for a long time. i dont know any customer of mine that would rather replace it than give the flare nut a quick tighten if that was an option!!!
@Goodrich90mxr Flare nuts on any application will leak over time due to vibration. Tightening it up will solve the problem for 3-6 months on many systems but then it becomes a nuisance call. I myself can think of plenty of customers who would have the job done the right way with replacement of the TXV for a sweat fit one.
That 90 or should i say 110 is a separate issue entirely though lol
@g156xb Lack of cooling, but without knowing or seeing things like that you would probably never notice the leak. The Refrigerant is usually odorless. You would have to only open that unit to see the problem right away, but you should go over the usual suspects first. Dirty Filters, electrical issues, dirty blowers etc... 85% of your problems in the field will be electrical related. 15% will be bad soldering or hardware issues that just need replacement.
What a load of crap the epa puts out. They are close to Co.'s like DuPont etc... What better way to make money than to tell the public that r-22 is bad for the ozone's so all the A/C units sold over the years that cost thousands of dollars HAVE to be replaced with newer ones that cost more than those thousands of dollars. Ill fix em, but I will never sell crap to people.
@im415again If you look at the details the EPA states the R410a is actually more directly harmful to the environment than R22. The "Total Whole Environmental Impact" claims since 410a systems use less electricity they pollute less. It is based on dirty production of electrical power, not the chemical composition of the refrigerant. Personally, I believe it is financially encouragement, not environmental.
@loix22 Pump down requires isolation valves and it's pumped to the condenser NOT the compressor. If you do a pump down that wouldn't resolve the issue even after leak has been repaired, reason being that during operation the refrigerant leaked out while it was damaged and you don't have a proper charge in the system. You MUST reclaim it, repair leaks, put nitrogen in and let sit for a while, vacuum system with micron gauge, use scale to put proper charge back into the system.
well that looks like a pretty easy job reclaim the gas in the reclaim bottle vacume the system replace the tx valve pressure test with nitrogen than vacume the system again and re charge the system about a 2 hour job depending on the size of the system
@tm030118 u would leave that coil? its a crime.....its molded n dirty and leaky... why bother....its hell changing txv in those tiny coils...wow your not a true mechanic
It never fails to amaze me here if they find a small leak on a roof mounted AC condensor, they just dump the gas, make the repair vacuum and re-fill.Sounds reasonable till you realize 500Kilos were dumped! And there are thousands of Grockles soaking up the sun on Eilat's beaches with a feckin BIG HOLE in the ozone layer above Eilat.I only scuba dive and early morning before some dick head purges another 500Kg freon.
Do your research. DuPont owns the patents for most of the refrigerants. And it because of those expiring patents, that we are forced to use a new DuPont patanted products that is worse than the original. Not to mention, freon doesn't harm the atmosphere near as much as mother Nature. The Global Warming fiasco is a hoax in case you missed current events.
well.. i want to take freon out of my fridge myself. but i lack information and equipment to do so. i dont want to pay someone to take it out for me. what can i do?
@W1LDWESLEY cut the lines, and don't let anyone see you... other then that if you are not a trained tech, there really isn't a simple explanation that you are going to get from youtube.

I have to wonder if the EPA could fine the original installer because his/her substandard work caused R-22 was discharged into the atmosphere.

@tm030118
Txv is just loose at the nut... but
Look at the Kinked Evaporator Pipe (above it ) at the Txv Outlet / Evaporator inlet.
feeding into the coil...that's the Real Problem. smashed over Pipe. that pipes supposed to be straight!
