Finding a Refrigerant Leak & Suprise!

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.

@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

@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.

@tm030118 you would seriously repair that instead of claiming big money to change that evap coil?

@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.

why is it said that it was an easy leak fix?

@tm030118 a vacuum alone takes more than 2 hrs...if you use a micron gauge and get <500mics
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
Yea, You are Right on the Money With that.

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

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!
