Model AW08ECB7 Samsung air conditioner. In attempting to drill a hole in the frame to allow the water to drain, I punctured the refrigerant line and all the coolant blew out. Can it be repair or do I have an eighty pound paper weight now?

Re: Leak repair Samsung window air conditioner
Modern window units intentionally do not allow the water to drain directly, they want the fan blade to sling the water on to the condensor (the coil that is outside) to aid in cooling actually helps the unit cool better in high outside temps, it also evaporates it this way, depending on where the hole was drilled it may be able to be repaired, if it was just a copper tube it will be less expensive than replacing the whole coil. Since its a relative inexpensive unit anyway the labor and freon may be more than its worth. Lesson learned dont drill a hole in the base it lowers it's efficiency and can lead to a punctured freon line.

If you look inside the exterior part you should see a copper tube(part of the refrigeration tubing) that rests horizontally under this water. The water cools the freon inside that copper tube. That's why some models don't have a drain there.
Put in a new piece of tubeing.First cut out hole, swag !a new piece of tubeing on both ends to fit over existing tube after claning and fluxing both ends of all four connecting pieces. Then silver solder all. Refill unit with the correct freon. Ifyournot familuarwith HVAC unitsI would suggest gtting profesonial helpl .
Here is a thought, received by me from a AC mechanic recently. Window ACs no longer actually drain concensate. Rather, the water is caught in a pan with the idea it will evaporate back into the outside air. The reason for this is the dripping water frequently resulted in the growth of algae below the unit resulting is unsightly stains and sometimes, slippery conditions. Evidently, there were a lot of complaints about being 'dripped on' also. So, AC manufacturers don't put drain holes in the bottom any more. If the pan over fills, it will spill out of many makes. If you want yours to drain, put a hole in the bottom.
Hi, On many of the newer air conditioners they intentionally keep some water in there so that it splashes onto the condenser coil and helps to cool it....while this may work well it also creates more noise....so I often recommend to drill a drain hole in the back corner...jus drill down from the top...drilling up from the bottom is a great way to drill right through the coil....
On most new units, the water left in the tray is picked
up by the fan motor blade which kind of cools the unit down.
On some models there is a round hole on the bottom left hand corner on the back of the unit. Really hard to
get a fitting between condensor coil and frame,but it
can be done. However the manufactuer will usually state if a drain has to be run if it is needed
sounds like your condensate drain is stopping up or not draining properly. I would check and make sure the unit's drain is open and water is draining.
Also it's possible that the AC itself needs to be tilted (just slightly back in order for the water to drain better. Sometimes people will make sure the unit is installed perfectly level for cosmetic purposes not realizing that the water needs to drain out the back of the AC.
when the freon is released from the unit,you have to repair the leak,pull a vacumm to rid any moisture in system then refill with freon,if you dont have the equipment,it would be cheaper to just replace the unit
The likely reasons for a leaking AC are...
1) Improperly installed. A window air conditioner must be slightly lower at the rear than the front. This allows the water being removed from the room to drain to the back of the machine. A difference of one inch is sufficient. This is always the first thing to check. Many are improperly installed in the haste to get relief from the heat. If installed too low at front the water will flow into the room rather than outside. If installed too low at rear, water can roll out front edges before has chance to exit towards rear drain.
Icing up. Water being de-humidified can turn to ice if there are problems with the cooling system. There are many reasons for an air conditioner to produce ice. Remove front grille while machine is operating. If ice is present on the cooling coil you will probably need service. For more information see our other article:Why window Air Conditioners Ice up.
Air leakage around air conditioner. If warm air is able to enter around the air conditioner it will encounter cooler, dryer air. When they meet condensation will occur. If water leaking from front of air conditioner inspect to see if dripping from body of machine, or water droplets clinging to front area. To test, operate machine for 30 minutes and then use flashlight to check under front edge of base. Small water droplets here indicate an air leakage problem. Add foam insulation to stop warm air from infiltrating.
Drain hole blocked. Rear of air conditioner base has a drain hole or groove to allow water to escape. If becomes blocked water can back up. To test, operate machine for 30 minutes and then inspect if draining properly. If appears blocked use a small piece of wood to open drain hole at rear of metal base. CAUTION: Never be tempted to drill holes into the air conditioner body to relieve water pooling. Severe damage can result.
Internal drains blocked. There are small passageways that allow water to drain from front of air conditioner to the rear. If they become blocked water will pool at front of machine and overflow onto floor. If this happens the air conditioner will require removal from window and servicing.
Outside temperature too cold. This occurs at end of cooling season. If outside temperatures drops below 60 degrees Fahrenheit at night the cooling coil may ice up. If no leakage at bedtime but water in front of machine in morning, suspect this problem. If this problem suspected turn off machine before bedtime and restart as day warms. Alternately, operate machine at night with selector switch in ‘fan only’ position. This will circulate room air during night but not allow cooling.
