Leak on home A/C

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?

    I had a/c tech recharge my system to 75 psi and two weeks later it's at 52 psi and he said that he was not able to locate any oil stain? I'm afraid that I will be back at "0" in two more weeks. How do the soap and water work? When do you apply this solution?

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.

Hope this helps

    The soap solution works by adding 1tsb to 1 quart of water then mix it well in a spray bottle spray all areas and watch for bubbles to appear. Sometimes this will give you a false reading though if the air moving arond is strong enough to create the solution to sud.

1. use stop leak,(New heavy-duty stopleak product XL-4 ) because it is very difficult to find where is leaking.

2. connect to the low pressure fitting of the condenser and use the A/C gage meter to add ES-22a or R-22 until reach to 75 to 85 psi if the temperature is around 90 degree.

3. turn on the A/C and re-charge ES-22a or R-22.

4.If you do not know how to do it,hire a professional A/C man to do it.

Hello, I have a split level Samsung AC unit. Recently the outside unit formed ice on it, so i had a tech look at it and he said that it was freon low level prob, so we got the level back up and it ran for...


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.

My Weather King AC unit model number 13AJA48A01 is freezing over. What can I do to fix it.


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.

I have Fiait Uno. I have peculiear problem. Ac gas reduces in 3-4 months. But when checked there is no leakage. What I should do?


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.

AC ran for a couple of hours and started blowing


If it is icing over, it is low on freon. You might have a freon leak if the system is relatively new. It will take a licensed tech to check, fix leak and recharge.

Motor home AC not cooling


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.

2002 TRANE XE 1000 AC - small leak


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.

Central AC unit not cooling


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.

Carrier indoor coil replacement


yup, entire system needs to be drained, and leak needs to be repaired first before charging with freon.

after sealing the leak and test it is ok, evacuate the system for about 30 mins before charging it.

you may need a qualified tech to do that because you can not buy freon now a days.

you need to weld the leak also. you will need portable torch to weld copper pipes.

you will need vacuum pump to evacuate the system before charging with freon 22.

AC WON'T COOL


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.
