You will have to get freon from a supplier such as Aireco, or R.E. Michaels. In order to buy it, you have to be CFC certified. If you want to fix the hole, you will have to be very careful, and cut the fins away from the hole in the coil. Then you will have to get a torch (map gas, acetelyne, etc) and solder it closed. Do not use plumbers solder, use a high silver content such as a brazing rod. Then after you seal the hole, you can hook an air compressor up to it, and pump about 100 to 150psi in to leak check your repair. If all holds well, you should be able to charge it. You may be able to find some R22 on ebay. I sell it on there sometimes. There are a lot of suppliers. Hope that helps

Portable haier air conditioner drainage. Cannot find drain hole and unable to tilt ac. Water is building up in the bottom of unit.


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.

Like I said, just a thought.

Thanks for your question @ FixYa.com

Looking for the drain holes in the trunk of the car, both sides are holding water


if you can not find the drain holes which are fairly small drill as 3/8" hole in the lowest point and push in a rod about the same size and draw the rod back towards the rear of the vehicle. That way the tires will not throw any road debries up inside the hole and the hole is large enough at all time to drain. At Zeibart years back that was done to all rear quarter panels and rocker panels for better drainage

We have a hotpoint RLA 34 ( MICROBAN ) FRIDGE . water keeps seeping into the bottom , under the crisper box tried turnining temp down , made sure it's level , no blocked drainage hole . door shuts tight...


You said no blocked drainage hole, where was the drainage hole that you checked located? Did you pour water down this drain, and furthermore did you check that the water you poured into the drain flowed into the condensate pan on the outside of the fridge? Unless you have a problem with an ice maker leaking water, it sounds very much like you do have a blocked drainage hole, otherwise known as a defrost drain. the drain system begins underneath the evaporator coil inside the freezer, this is where the water that is collected in the defrost cycle flows into a drain tube that leads the water down to the condensate pan. The best and safest way to clear out this drain is to blow it out with compressed air, after you remove any and all ice at the beginning of the drainage system, in other words, the hole located underneath the evaporator coil.

Hi,
You just drilled through one of the refrigerant coils....the freon is escaping...
This is not repairable so you will have to scrape the refrigerator now and buy a new one...

Sorry...wish I could give you better news...

I have 2 Gibson AC's that are thru mounted that have worked well over the years with some water issues. WE have cleaned them without removing them from the windows with good success each year. Now, both of...


DONT DRILL A HOLE! It is to easy to drill through a refrigerant line and that's big problems. Water in the bottom of the unit is normal and there is usually a water slinger on the outside fan that blows the water on the condenser coil. Its good that you have checked the slope on the unit. It seems odd that both units started doing this at the same time. The water flows whereever it can from the front of the unit to the back. Probably the units are quite dirty and need cleaned. The dirt in the corners of the pans where the coils set can stop the flow of water through the pan.

In drilling out a clogged drain hole, I accidentally drilled into one of the aluminum coil tubes. The puncture is very snall, but nevertheless the gas escaped.What have I got to do to fix this/ Thanks


In my opinion it is better to get an a.c technician to repair the tube, and then they have to vacuum it to see if there is not another leak. Then they will add freon again.

Punctured a hole in air condtioner..HELP


The only sure way to repair the unit is to replace the condensor coil. Pressures are too great for a patch job.

AC accumulating water, not draining properly????


For some reason, newer AC window units no longer are made with a fluid drain. I think the intent is for the unit to be mounted at a sufficient angle (it MUST be angled back so the fluid drains toward the back of the unit) that the rear (outside) fan kicks the water over the condenser coil and gets rid of it that way, it also increases cooling ability slightly in this manner by misting the condenser coil. I would suggest increasing the angle of the back tilt by adding a 2x4 maybe under the unit to allow it to tilt? Alternately, you can drill a hole in the rear corner of the unit to drain fluid, but this is not recommended for several reasons...

1) It will usually cause rust to start at the drill hole.
2) you could accidentally puncture the coil system while drilling
3) the manufacturer did not make a hole, because one was not intended.

Is there a drainage plug or hose on the air conditioner? It's leaking.


To increase the efficiency of the air conditioner's cooling to meet US energy requirements, most manufacturers eliminated the traditional drain plug. Instead, they switched to a design that used the extracted moisture from the room to help evaporatively cool the condenser.

To do this, the traditional fan blade was replaced with a 'sling blade' which was a fan blade with a rim or ring around it. The drain plug or drain hole in the bottom of the pan was eliminated and replaced with overflow notches in the back edge. Along with a solid piece drain pan, this provided a pool of water for the edge of the sling blade to dip into and pick up water to 'sling' or spray around the compartment to create evaporative cooling. The overflow notches established the maximum depth of the water pool and are also the lowest place when installed properly.

Although this is more efficient, this has caused 2 problems: increased noise as the water is slung around and water spray from the side air vents.

Persons have drilled holes through the pan or back edge as drains. This is not recommended as it negatively effects the colling ability of the unit and could lead to a voided warranty or premature failure.

Instead, insure that there is adequate pitch with the installation and make sure the overflow notches are kept clear.

If you 'need' a drain hose, my suggestion would be to drill into drain pan's back edge or the rear potions of the sides. The hole should be at the same level as the overflow notches. Once the drain hose is installed, block/cover the overflow notches to redirect the excess water to the drain hose instead.
