Authors’ Introduction. Go to to listen to Junko’s unit introduction. The Issue. In this unit, a guy comes to a job interview with green hair . COFFE PEOPLE SNAP in YOKOHAMA: Junko Hata. Junko Hataのスナップ. ニックネーム: Junko Hata; 仕事: Elliot Avenue, owner; Photo by: Nik van der Giesen. You are now the proud owner of a STORK unit, carrier pilot of the JUNKO units will at least attempt to apologize if your STORK unit gets upset.

If refrigerant is missing, the air-conditioner leaks; if the leak is not fixed, it will continue to leak. A window unit is almost always a bad economic choice to attempt repairs on rather than replacement; since USA-based persons DO need a license to handle refrigerants, and anyone world-wide junki specialized equipment and one, hopes, enough training to use it correctlythe cost of service particularly with older, unjr expensive refrigerants is far above replacement, particularly when the power efficiency of a newer unit when running is factored into the equation.
The cost of having a qualified, equipped person or becoming that person find and repair the leak on a unit typically not made with ease of service and repair in mind will almost always exceed the cost of a new unit to replace it.
First, you’ll want to fix your Freon leak. After all, air conditioners are generally sealed units, with only jhnko wires entering the envelope that contains freon. However, they use a lot of aluminum, as it is junio superb themal conductor, and cheap. Accumulated junkl in the cooling coils and fins tends to hold water, a perfect storm for aluminum corrosion.
Good chance you have a pinhole in the condenser. Likely you have a foreign made pile of junko, so there is nothing in the unit designed to help you.
Every inch of tubing in the unit is welded, and there are no spare parts to be had for the mechanical package.
If you have an old school solid American unit, unid most likely takes the long-discontinued R12 or R22 Freon, so you are paying top dollar for old stocks. Contrary to what comic books say, a Freon accident will not turn you into Mr.
Cold is not like fire, you don’t instantly feel the pain, you can expose jun,o long enough to do damage before you realize it.
And there you are, using third party parts of dubious quality, since no manufacturer endorses even authorized repair of the Freon containing machinery – it is not economical even if they made it easy, which is why they don’t. If it’s you, you’re paying again to run an old inefficient unit. My friend just bought a private label no-brand junko unit that did BTU for 5 amps.
An older unit would be even worse. This is due to Federal laws requiring ever-increasing efficiency.

Then imagine what a quality unit would do. Even if you can get 5 more years out of your old unit, the new unit will pay for itself in electricity costs alone, to say nothing of all that other stuff.
You are supposed to be EPA certified to work with freon, so the following is only for educational purposes and some pertinent information may be missing. An air conditioner should be cooling the air by about 15 to 20 degrees Fahrenheit. To check that, hold a thermometer in front of the air conditioner where the air is comming out. It should be about 15 to 20 degrees cooler than the temperature of the air in the room more specifically, 15 to 20 degrees less than the air going into the air conditioner.
RA also called Puron is the standard as of A 5 ton AC unit has 10 to 20 pounds and a 3 ton AC unit has about 6 to 12 pounds of freon. What do I mean by tons? Tons are kind of like horse power.
Tons refers to the amount of ice that would be used to remove a similar amount of heat and for window AC units, it’s around 3 to 5 tons per hour. R22 systems use mineral oil for lubrication whereas RA uses a synthetic polyolester oil.
Mixing refrigerants is illegal in USA. The larger copper tube leading to the compressor is the low presure side and the smaller unirr is the high pressure side. Generally, about 1 or 2 pounds of refrigerant should be enough to top off one AC unit.
How do you measure that? One way is to put the canister of refrigerant on a bathroom scale juunko weigh it Measure the temperature to see if you need refrigerant. Check the make and model of the air conditioner to find out if you need R22 or RA. If you need R22 the cheapest option would be to replace the window unit.
Measure the size of the low pressure tube and order a self piercing valve. Order the refrigerant and any necessary hoses or connectors.
Turn on the AC unit max-high jubko add the refrigerant while it is running warning!!! Don’t forget the bathroom scale, to weigh the canister before and after.
The freon wasn’t beamed out by Geordi LaForge. For the vast majority of window unit air conditioners, you can buy a new one cheaper. And then the energy savings from the more-efficient new ones will pay you further dividends. In all my years I have seen but one window unit with a schrader valve on it.

I threw it away anyway, because: They’re sealed systems for a reason. If you’ve lost freon, it’s because you have a fracture in the tubing that will quickly leak out what you put in. Mazura – exactly, the Shrader valve is a designed in leak. Poor design as all the wall unit AC and refrigerators I ever worked on had exactly the same amount of freon they left the factory with, unless someone defrosted them with an icepick or did other system breaching damage.
Air unirr do not magically lose refrigerant. It’s a waste of money to try. Especially if you’re the guy who pays for the electricity.
Captain Kirk didn’t beam the Freon out. Refilling is dangerous Contrary to what comic books say, a Freon accident will not turn you into Mr. Who pays the electricity bill?
So fixing an old unit is a false economy. What you need to know: Most window units do not have a port installed so that you can add freon. You probably won’t need to add more oil.
What you need to do: Here’s a few youtube videos with some extra info: I own most of the equipment to do this with, but I never would then again I horde old window units in my basement, so that I can lend, abuse, or toss-and-replace them at will because “Most window units do not have a port installed so that you can add freon. Once a window unit leaks, it’s done IMO.
