    This is Split Type office air conditioner. Not a central one. Has its own indoor and out door unit.

    Sometimes the reffrigersnt can leak at the schreader valves, this is usually a slow leak. You can check with some soap moxed with water, if you see big bubbles there is a leak

SOURCE: Fair price to fix central air conditioner leak & refill with freon

I have heard that there is a spray you can use that will not damage your system and seals the leak when it comes in contact with oxygen

SOURCE: System pressure for puron read 280 and 135 for low

the system must be leak checked, refrigerant recovered, evacuated, a drier installed, and recharged to the correct subcooling, (I assume this is a carrier since you reference "puron")
the low side pressure seems to be in line the high side pressure would be low depending on operating conditons, these systems must be charged using superheat and subcooling methods, pressures are just a "starting point"

The leakage is probably from condensation and there should be some sort of drain for it. You should check to see if it is clogged or partially clogged. Also since you say it does it when it hasn't operated for a while you may want to check out where the lines pass through the wall and make sure that it is sealed up there so you don't get leakage from out side.

SOURCE: Leaking Haier Commercial Cool air conditioner.

there are 3 drain holes in the primary pan right underneath the evaporator that need to be clean with a pipe cleaner or a wire of somekind and there is also a secondary drain behind it that will work only if the unit is 100% level. To access the primary drain pan you have to take all the screws of the back cover 5 on each side and 3 in the center above the electric cord and behind the air filter and only then will you be able to see these very small holes. Use a flashlight to make sure. Have fun!Reply

GE Monogram built-in loses gas within 2 days

You need to find out where the leak is located to repair otherwise if you continue to charge with Freon the fridge is going to get moisture inside the sealed system. A lot of times the evaporator will leak causing moisture to be pulled in. The leak could also be in the condenser coils or the yoder loop.Can you charge it again and use soapy water to help you to locate the leak? Are you equipped to repair the refrigerator? Thanks John Tripp Sea Breeze

Anyone else have a Amana refrigerator AFD2535FES develop a refrigerant leak in the sealed cabinet?

You can seal off those lines going around the door that's called the Yoder Loop. but as far as the class action lawsuit or getting Amana or Whirlpool to pay for the anything good luck. There are very few success stories there.

Yamaha Motorcycl xt225 leaks gas through carburetor wont start

Check your oil it , may be full of gas. Your float needle is either stuck or your float is saturated and sunk. Take apart your carb and clean it. Place your float in gas to see if it sinks. Inspect your needle for tip damage or wear on the sides , if visible damage replace. Inspect the tank and carb bowl for rust or dirt this can make your needle stick. You have to add an in line fuel filter. Always turn your fuel off when not riding. If your spark plug is wet fouled with ethanol fuel , replace the plug with a fresh one.

The freezer is working ok but the refrigerator is not cold enough and there is water on the floor of the frig.

have your fridge checked out by an expert because you can have a gas leak that cause your fridge to be low on refrigerant. sometimes gas leaks are visible at the back but will have to be repaired by an expert.

Refrigerator stopped cooling & freezing

2 possibilities here, the defrost system has mailfunctioned, this is realitevitaly cheap to fix, 2 parts are most likely at fualt, The defrost timer or the defrost eliment, failing it is either of the previously mentioned you may have had a brazed joint failure and the gas has leaked, with domestic fridges if a gas leak has occured it is usualy cheaper to replace the entire unit.

Should it be a part of the defrost system how ever then it is best to have it repaired, to find out which you will need a fridge tech to come and see it in person!

There's no voltage to the clutch when actvated. The compressor looks to be original and have a feeling that it probably needs to be replaced.

No voltage to the compressor clutch is usually do to insufficient refrigerant gas in the system.
There is a low (refrigerant) pressure switch in series with the A/C clutch control - if the gas pressure is too low, it inhibits clutch control.

Get the system topped up with refrigerant and checked for leaks.
A UV visible dye can be included with the refrigerant top up - leaks are then visible using a 'black light' test unit.

Beverage air dd58 kegerator won't stay cold

The unit is probably low on gas again. If it lasts a month the leak may be difficult to find, as it may be a small leak. Those units don't hold a lot of gas. Have someone do a nitrogen leak check and fix the leak. If no leak is found, have them install a UV dye to help find the leak. :)

Air-con problem

if you are filling gas, then you could have a small leak that lasts for 5 months.

normally we do find leaks at the evaporator coils. you can test your charge if you know how and if it is low, then you really have a leak, if the gas is empty, then you have a big leak.

to find the leak, trace the refrigerant lines from the compressor to the hoses to the condenser, filter dryer and evaporator.

look for oil stains. refrigerant leak leaves an oil stain where the leak is.

but it would be a big job if you have a leak in the evaporator plus you will need a qualified tech to service your vehicle.

what you can do for now is buy those small charge of refrigerant and if you can charge your system then charge it but be very careful in handling refrigerant. they can be fatal.

i hope i was able to give you insights on what you're problem is.

tnx 4 using fixya,
