What to do about a freon leak after having freon placed and inside furnace coils continue to freeze up?
ANSWER: Contact the manufacturer and inquire if they repair or replace the units with freon leaks. Also ask them if they can refer a repair shop near the town you live in. Quite simply, putting more freon in it will leak out and it will keep freezing up. Fix the leak. >>>> More times than not the leak is not in the coils. It could be any one of the 4 piping connections (2 on the furnace and 2 on the condenser) and if the installer did not use a single line set, any of those additional joints as well or somewhere else in the condenser. Coil leaks are rare for the most part. Usually the hardest part of leak repair is finding it.

What causes the AC compressor to continue running and the freon to continue to circulate after the fan inside the house clicks off?
Main components of AC are compressor & fan motor. The louvers are operated by fan motor which is powered separately. When the louver is off, it doesn't affect compressor work. - Be-Cool Expert possibly a stuck contacter in the outdoor unit. or your indoor fan is overheating and shutting o…ff could be many different things. Depends on what system you have. Some of the newer machines are controlled by integrated circuit boards. Its a possibility that your indoor blower could be tripped off on thermal overload but honestly I doubt it. Possible contact could be stuck on compressor. T stat could have a problem but would need to know if the compressor ever turns off after the "fan inside the house clicks off" ( Full Answer )

There are a couple of automotive A/C leak detection methods; sometimes you can find the leak by looking for oil and dirt residue on connections, hoses or on the compressor. Some shops like to charge the system up with R134a, use an electronic leak detector to locate the leak and if that doesn't pinp…oint it, add a florescent dye to the system which you can look for with a UV/black light when it leaks out. I personally would pull a vacuum, add about 4oz of R-22, pressure the system up with 200 PSI of dry nitrogen, then go over the hoses and external components with a soapy water solution, then check the evaporator and shaft seal on the compressor with an electronic leak detector. I always find my leak! ( Full Answer )
Why are the outside AC coils freezing and how do I CHECK for low levels of freon before calling a technician?
How do you know it's a blockage in the line, and not a leak causing me to have low freon levels? \nThanks.\n. \n Answer \n. \nYou probably Have a blockage in the line posssibly in the orifice expansion tube. Find an A/C Service tech ASAP. Do not continue to run more damage may occur.

Freon is a coolant/refrigerant used in A/C's or refrigerators to cool the air. It is illegal in some states so check before use. California mandates R-134a as a alternative.
It won't be cooling very lomg. Better yet check and clena the all the coils,
Yes it can cause you to become dizzy,light headed and sleepy from what i understand after talking to the EPA. We are having a problem with freon leaking into our home with small children present after faulty work on our central air system.
Out of the MANY different types of air conditioning and freon, I can safely say many of them use oils that are brightly colored. Green, fluorescent green to be clear. And I do mean a green that will startle you in any quantity. The oil usually has a near mineral oil smell. It is very thin as oils go…, and will spread out over a large area typically becoming so thin that color is hard to determine if an oily spot is found. These oily spots indicate a leak. Note: some appear yellowish but all that I have seen are very very noticeable. ( Full Answer )
You can save some of it by:\nClose condenser valve to evap coil - Use guages to prevent exceeded max pressure. Run compressor to store gas in condenser.\nCut off evap return line at compresser. Replace evap.
It a word, no. Without a leak, the freon level in your unit should stay the same for years and years.
An AC unit in our office leaked freon. In order to repair the unit, the mechnaic had to weld the unit to avoid continuous leaks going forward. The employees in the office were concerned the freon leak could be harmful to the office air/environment. Is this something we should be concerned about or o…nce cleaned up and repaired is there no longer an issue?. A: In terms of your immediate health, no. Freon is not dangerous other than that it can suffocate you like any other gas if it displaces the oxygen in the room. This would require a significant leak in a closed room with poor circulation. Since you're asking the question, I assume you survived.... In terms of the environment, some freons destroy the ozone layer and most freons are VERY potent greenhouse gases. So yes, they can create environmental problems, but no, they are not dangerous in a sense of being toxic. ( Full Answer )
As this is not a "Do-It-Yourself" kind of job, the best advice anyone can give to you is to call a licensed Heating and Ventilation engineer to advise you.
The two basic ways are:. 1. charge the system with refrigerant containing a tracer dye, then use an ultraviolet lamp to find the dye at the leak point.. 2. use an electronic leak detector, commonly called a 'sniffer' to find the leak.. Pressures in an air conditioner can be dangerous. Working on …the system requires specialized knowledge. Get some help from an experienced refrigeration tech. ( Full Answer )
Evaporator and suction line(the largest line) will ice up, house will get hot. pressures will be very lo
Freon leaks are not dangerous. To pose any health risks, the amountof Freon would have to be more than the amount of oxygen in theroom.
Refrigerant (freon) does not freeze, at least not at any temperatures one could comprehend let alone encounter here on earth. It is used in cooling/refrigeration systems for it`s favorable boiling temperatures. If that is what you are asking, the answer would depend on a few things, such as type of …refrigerant and the temperature and pressure of the vessel containing it. I`ll give an example using R-22 the most common refrigerant used for household cooling systems. At atmospheric pressure at sealevel (0psig/14.7psia). R-22 boils at -60*F, releasing liquid R-22 directly from it`s container would cool whatever surface it came into contact with to this temp and it would create a nasty burn type injury (frostbite) if that surface happens to be your skin. But, in a properly operating a/c system a typical low side pressure would be around 70psig, under this pressure the refrigerant boiling point is raised from from -60*F to +40*F, producing appx 50*F discharge air into the home. For a more detailed explanation see my answer to: How does air conditioning work? on this site. ( Full Answer )
You have a strange odor coming from your home AC unit you were told yesterday that the freon is leaking from the coils does this right?
You would not smell the refrigerant as it is odorless, you may however smell the oil that circulates along with it. But if the leak was that large where you could smell it, it most likely would have been one single event NOT a continuous one and the unit would be totally out of gas and non functiona…l.

Refrigerants do not freeze. They are used due to their favorably low boiling points, so I am going to assume that is what you are asking. The answer would be R-12 which boils at -21.6*F where R-11 boils at 74.7*F. These listed boiling points are at atmospheric pressure at sea level (0 psig/ 14.7 psi…a). ( Full Answer )

The coil you are referring to is the evaporator, it is inside the air-handler, which also contains the heater. The evaporator freezes up when the air conditionong system is low on refrigerant. What happens, is that since the refrigerant is low, it expands more than normal which cools the evaporator …more than it is designed to. As the air passes throught the evaporator, moisture in the air freezes on the cold evaporator fins. This will eventually turn into a block of ice, which will impede the air flow. Once the air flow is restricted, the air conditioner will not cool very efficently if at all. Remember that the air conditioner vapor system is a sealed system. The refrigerant will last forever unless it leaks out, so you need to find and repair the leak to stop it from re-occuring. Some companies will just recharge it, especially if it's a very small leak. That way, you'll have to call them again when it starts to freeze up. ( Full Answer )
It needs to be looked at by a pro, too many possible causes for this (usually simple ones) to diagnose accurately from here.
you need to be certified to purchase R12 Freon, i think they even took it off the market due to environment issues....
Freon could be leaking anywhere in the ac system. A colored dye canbe added to the system, then seen with a special light to find theleak.
remove freon,pressure up system with dry nitrogen to 250psi & go over it all with soap & water .
R22 (commonly referred to by the brand Freon) is not a toxic substance. Its main danger would be the potential for oxygen displacement just as any other gas that is heavier than air, causing symptoms of asphyxiation. Some people may be highly sensitive to environmental substances in general, and hav…e an asthmatic type response to R22. In the scope of a home system for example, unless the system is leaking the better portion of its charge in a matter of a day or two, there is no danger to the home or inhabitants. In rare cases, very rare, ammonia or an uncommon refrigerant could be used, but the majority of home A/C's for generations have been R22. ( Full Answer )
There are two ways to answer this questionTechnically : if the leak is into the system where the pressure is low ( low side ) , leaving it on will make the remaining refrigerant last longer , where as if it is on the part of the system where the pressure is high , it will escape faster , but on the …other hand the motor inside the sealed refrigerant compressor need some ways to cool itself since it generate heat , and this is accomplished with the cool refrigerant gazes coming back to it after the completion of the cooling process ... this is to say that if you have a leak on the low side of the system , and you make a choice to leave the appliance on , you will eventually burn the motor inside the compressor , so you are far better to have somebody fix the leak before you get more problems ... note that this is also true for a lot of refrigeration equipment using sealed compressors like your home central air conditioning system and many others ! Practically : Say you decide to stop it for a little while till you get somebody to fix it , it is good practice to keep the doors open to prevent the remaining humidity to turn into mushrooms and mold and contaminating the appliance with a smell that maybe there for a long time to come ... even after you put in back into operation . And this bring a new question into my mind : what good is it to have a refrigerator if it is stop ? ( Full Answer )
Freon-22 freezes at -256 degrees F. Liquid Freon-22 will freeze your skin on contact. The HVAC Veteran
If you are trying to check the freon level by looking at the slight glass then don't, reason is that its also called an idiot glass (no disrespect) but the glass can show clear and the a/c system can be both overcharged as well as undercharged..

The easiest way is to add freon and an oil with a dye additive and use a florescent light and yellow goggles to pinpoint the leak/leaks........
There are UV leak detection kits you can purchase at all most any automotive store which have UV dyes, lights and glasses that will help you locate a leak.
No, if you are losing refrigerant you will soon not have any A/C. Also the EPA states that this is hazardous to the environment. There are many products that you can purchase from UV to find the leak to products that have sealers in them. Its best to get the leak taking care of as soon as possible, …depending on how old your compressor is it can burn it up and that is very costly to replace. You can find more helpful tips on the website link below. ( Full Answer )
A leak is the only way to loose volume of the freon charge. Freon is in a sealed system and it does not get used up. If your system is tight the freon will last forever. However a restriction in the freon lines can cause the freon pressure on the low side to look like it is low but the freon is real…ly stacking up in the condensor. ( Full Answer )
Freon is odorless, but it is possible to smell the refrigerant oil that could also be leaking.
no. How could you have a leak without a leak? There's a hole in the system somewhere.
If the leak was large enough to displace all of the oxygen, you would die of suffocation.
Bottom line: Start by checking the ducts and turning up the thermostat a few degrees. If you still have problems call a pro. Reason: The most common cause of icing on the evaporator coils is insufficient air flow. Check to make sure the ducts are clear of any obstructions or debris, particularl…y the inlet duct. Also make sure that you have not closed too many of your outlet registers. If there is plenty of airflow but you are still getting icing, you are probably over-working the system. You may need to turn up your thermostat and deal with slightly warmer indoor temperatures until the weather cools off. One final possibility, some systems have a hot gas bypass valve to prevent icing and if it is not functioning properly, that could be the culprit. I mention this last because it is not very common in home air-conditioners. If yours has one and it isn't working that would require professional assistance to diagnose and repair. ( Full Answer )
The cooling coils are very small in domestic freazers. Yes it is possable to stop the leak however it may take more time, and labor cost to find the leak than it would to replace the unit outrite.
it will give you a head ache and get you high if you inhale right by the leak, but it wont seep through your vents and make you sleepy
It is advisable to call a technician to repair your air conditioning. He will solder the damaged pipe so that the freon wont leak anymore. Besides being dangerous, the lack of freon makes your air conditioner to work badly, and even stop refrigerating.
Freon is a nerve gas and will cause you to twitch over time. More immediate effects would be death by asphyxiation. Freon is heavier than air and if breathed it will settle in the bottom of your lungs and not come out. Have your Technician check your system and if he adds freon but does not fix the …leak fire him immediately and please contact the EPA for this is very dangerous and illegal. Not to mention the fact that it is a huge rip-off to the customer. ( Full Answer )
no the freon is strictly for making cold when the a/c is being used in the summertime and what makes the heater core works when heat is needed is the coolant
If you have the car running and freon 12 gets in the air cleaner mixes with r12 you have fosgene gas the same stuff used in world war 1 its a nerve gas be carful
definately, they are schrader valves just like in your tires. I've replaced many of them for leaking. Sometimes they are sold seperately, but other times they are made into the line.
No - actually, it'll have a more opposite effect. The superheat will be low, system pressure will be high, and the result will be insufficient cooling.
Well, it can be done, but it's a bit redundant to do it before you have the leak repaired. Recharging refrigerant in an HVAC system isn't cheap, so it would make sense that you'd want to ensure that you needed it done as little as possible. Also, if the technician recharging the refrigerant detects …the leak (which they probably will, as they'll do a performance system test with a pressure gauge when they come to service the system), they may refuse to charge the system, as the law prohibits them from doing anything which they know will release refrigerant into the atmosphere.

If the refrigerant has leaked out, then you can not do a homerepair. you need to replace all the pipework and get someone tocome in and re pressurise the system. This is a job for aprofessional.
