My home AC was low on freon. I had a cert. tech charge the system back up to where it should be, but he never checked for leaks. 4 weeks later, same problem. I used soapy water to locate the leak myself, which is on a copper pipe just outside the condensor coils. My question is, is it ok to solder up the leak without removing the freon from the system, or would this be dangerous?

Re: Leak on home A/C
You need to have the system evacuated to fix this leak. First thing is for safty reasons, for your protection and refrigerant release. second is to make sure no contaminates are released inside your system. The tech should recover the refrigerant fix the leak, then purge with nitrogen, then pull a deep vaccum to 500 microns and it should hold for 20 mins. then he should recharge the system with refrigerant.

Yes it is! These are sealed systems, so if the tech made no effort in locating your leak, it will continue to loose freon. We are required by the E.P A. law, to make every effort we can to locate the freon leak. We can get away the first time, but always check for any signs of leakage. How much freon did he add? Should say on the service order as we charge by the lb. Look on the data plate on the outdoor unit to see what it holds, and compare how much was added. The compressor is working overtime trying to keep up. I would schedule a leak check to take care of the problem. They will not let us keep coming out to add freon with out finding the leak, its changed so much do to our o-zone layer. Please rate me on my help to you.

Hello my name is Heath it will be my pleasure to assist you. First be sure that the blower is working next make sure the filter is not plugged. If these two things are okay then you probably have a low freon charge in the system. Which also means you have a leak so I would have the system leak checked and repaired before having someone just dump freon into the unit as its just going to leak back out.
if compressor is comin on an you r sure then you are low on freon,there is not a port to put freon in you would have purchase a tap valve on the bigger line then apply freon to it ,thats located inside of the system
the freon system is a sealed system. If the "Gas" keeps depleating, there has to be a leak. no question. If a tech is searching for a leak, request that he use dye in the system. This will show any leak in the system.
The only service ports that you are likely to find would be on the unit itself on the roof. I would imagine you'll probably have to open an axcess panel on the unit to get to these.
As far as what kind of refrigerant is in these usually that same axcess plate will tell you. I couldn't tell you right off hand but usually its r-410a or r-407c. Occasionally you'll find one with r-22 but again it's up to the manufacturer.
But before you decide to try adding refrigerant keep in mind that legally this should only be done by a qualified service person. Not to mention that there could be a host of electrical or mechanical causes for this. Adding freon is not always, and most typically never is, the problem.
Yes this could be caused by low freon but again, if that's the case then it is most likely leaking and will need to have the leak repaired. This could also be caused by, but not limited to: - a bad thermostat - a bad relay - a bad compressor - a malfunctioning expansion valve
In summary I would highly recommend not trying to do this one yourself without the proper tools. You may very well end up causing more damage than you solve.
that is no longer considered a small leak. having to add freon every 5 years is a small leak. you have a massive leak and it needs to be repaired or replaced imediately. you could be charged for freon release by the epa. check the coils and every joint and valve for oil drops or seepage or actual air leaks. for something that bad, you could use soapy water (dish soap) on the joints. where it bubbles is your leak. do not use soapy water on the evaporator (cold) coil. regardless, you need it repaired or replaced and it turned off until you can do so. it's either pay the epa $32,500, or get a new ac.
If you have access to your piping system you may use a soap bubbles to test the pipe connection. the leak gas will blow the bubbles if there is leaking. But if your system is out off freon gas, you can not use this method. just try it check the connection first put the bubbles around it.
Sounds like you have a freon leak or your compressor has stopped working. You will probably need a service tech. If it is out of freon, don't let them just add more freon, make them find and repair the leak first. Good Luck.
