What does freon in ac unit smell like?
There is no smell, unless somebody has used something like 22a freon which is actually propane and may have a sulphur smell

Freon is a brand name coined by Dupont. Most residential ac's use R-22 currently. Cost to the consumer is going to be around $39.80/lb. Capacity is going to vary by size of unit and different condenser/coil combinations. The average, if there is one, would be around 4 lbs. Another answer $40 a… pound plus $95 per hour labor. I called the best known heating and air company in town and they said $49 per lb. Another place said $44. I started calling some of the smaller guys and finally got answers around $35. My advice is make sure you call at least 4 places before hiring anyone. Another answer The cost of r-22 is going up every day, so every time you have your system recharged it will cost you more than the last time. June 3, 2009 Tulsa, OK -------- I paid $35 for a pound of R-22 today. Another answer Freon prices vary. A few factors involved in charging an a/c unit are the factory charge, linset length, and indoor coil size. It is a complex process which if completed properly will extend the life of the equipment. More important than price is the knowledge and ability to perform the function properly and finding and fixing the reason that is causing your a/c to leak. Instead of shopping for price, you should shop for personal recommendations from satisfied customers. Another answer In whittier, CA they charge anyone 15 dollars a pound for R22. (Certified tech with epa card.) Freon is R12. Do you really need Freon R12? If you need R22, which is not Freon, it's $45 a pound. (MORE)
When you put freon in the thing that looks like a radiator it leaks it out before it gets to the ac unit also the compressor does not kick in any answers?
Answer . \nYou arein over your head. Take it to a professional. You have neither the knowledge or tools to repair.
Answer . \nmy first response is why?...if you are not a trained technician, refrigerant gas can be potentially a dangerous substance. it is under high pressure and can cause burns!!..if the unit is not cooling properly, you have to figure out why. is the filter and or coil dirty? is the unit t…oo small?..is the thermostat not working properly? these and other questions must be answered before you delve into the refrigerant gas!!...hope this helps!!. Answer . you have to install a inline valve on the line it will install without loss of\nfreon then you can pump the freon out. (MORE)
Is it possible to replace the input valve on an AC unit where you put in the freon without having to replace the whole AC unit?
Answer . \nI dont understand what you mean by "the whole unit". There are many parts, including the service port, that are replaceable, but you still need to evacuate the refrigerant to change any one of them
Answer . 6 Cyl - Under the Air Filter Assembly. 4 Cyl - Looking at the engine, it is located on the left side behind the engine. Be aware that this location may require your hands/arms to be dangerously close to the belt pulleys when hooking up. It is a good idea to hook up connection with engin…e off, then start engine and charge A/C. When charge is complete, turn off engine then disconnect. Safety First! Good luck, I hope this info helps!

I have a three ton unit and when the AC guy came out and did a reading on my unit with a Yellow Jacket Manifold and it said something like 65 on the blue and 305 on the red gauge. I don't know what it means, but you probably can talk to a pro at home depot to find out more. Btw, I am by no means a p…rofessional and the only reason I wanted to know is so if they have to come out again and they check it, I can show them the previous reading, and they will know if it has a leak. One more thing. Another interesting step the AC man did was check the temperature of the air at the intake vent and at a regular vent that blows out air. The easiest way you can do this is by getting a cooking thermometer for a couple of dollars that goes to like 40 degrees and goes up to 100+ degrees. If the temperature is 20 degree drop from intake vent to blowing vent, your AC is working as it is intended. So before you call the AC man like I did, it is a good little test to do and it is better than paying the AC man $300 to tell you nothing is wrong. Another Opinion... A homeowner is not equipped to check the refrigerant levels in a residential unit. It is illegal and dangerous if you don't know what you are doing. Refrigerant is under pressure and if you are not careful, you can burn yourself to the point of frost bite in less than a couple of seconds and it could blow in your eyes causing instant blindness. Secondly, the pressures are not constant. They vary based on the ambient temperature. It takes a skilled tech to know how to properly assess the refrigerant level and determine if a machine is working properly. As a home owner, the best thing that you can do before calling on an expensive technician is to make sure your air filter is clean...restricted air flow will actually freeze up your system! The second thing is to be sure that your coils are clean on the condenser (outside unit.) If you are ambitious, you may be able to check the inside coils and blower blades to be sure they are clean. (BE SURE THE POWER SUPPLY IS OFF.) Finally, check the obvious...batteries in the thermostat and power to your system- did a breaker pop...if so, there may be a reason and this may be enough of a reason to call on your local technician. As for temperature drop, a good system should be able to cool the air about 20 degrees F. Measure this at the return going back to the air handler and again at a supply duct. (MORE)
Answer . \nBy buying an AC charge hose and a can or 2 of R134a freon (depending on how much your car needs) Attach hose to the low pressure side & charge system. Do not overcharge, or you may destroy the AC system.
Answer If the system is over 5 years old and especially if its using a fixed orifice on the cooling coil designed for R-22 refrigerant,, Then within 95% probability,,, ( NOPE ) If the system was bought in past couple of years, ( and this means INSIDE & OUTSIDE components ) it will specifically tell… you if you have such a capability to do the swap over plainly in your mfg. manual and most often will also state that both refrigerant types are acceptable for this system properly retrofitted. The Inside split system cooling coil is sized much different for these two refrigerants as that the normal pressures they operate at are extremely different. NEVER mix different type refrigerants in the field. Use one or the other, but never blended. There are R-22 replacement refrigerants available that will work without a retrofit. Still though, you will have to have the proper equipment to remove all the old refrigerant from you system and recover it properly so that it can be taken and checked into a E.P.A. Recycling Approved Center. There are safe replacement specifically designed and on the market to keep them in operation for awhile. The newer R410A refrigerant is a good one and has some very very good qualities. It is also much safer for our environment than R-22. So it is a nice thing in my opinion. And R-22 is being phased out as you'll notice its price climbing much higher as it gets closer to that phase out date. Much the same as R-12 was done. (MORE)
What could a noxious chemical odor coming from a turned-off convector AC heat unit be if it's not natural gas but smells like the self-cleaning oven smell?
Answer . \nHi:\n. \nWow,,,, this question kinda leaves me hangin on details I need , But! ( it is a bonefide good one ) and I think it\ndeserves at least an attempt on my part ( even though ) \nI am bit uneasy because of the lack of details I have been presented.\n. \nAnswer simplified,,,, it'…s probably a step down control transformer or pull in coil of some sort.\nThey give off a really pungit chemical odor when partially shorted or overloaded.\nAnother possibility is,,, A run capacitor or start capacitor on a fan motor or such.\nAnd yet another possiblility is, some modification that has been made through either a clean up process or repair or paint and or lubrication that has gone awry.\n. \nYou should have a real pro. come and check this baby out\nmy friend. It's probably not that big of a deal and a good\nhonest service tech. with good test equipment and skills can probably put your concerns at ease really quick!\nDon't USE it till you KNOW though.\n. \nHope this helps you out: \n. \n. \nJimiwane (MORE)
Odorless. What you are smelling is antifreeze, leaking from the heater core in your car. I DISAGREE: Freon smells a bit like ether and should not be inhaled. Freon is a gas that does not have a color or smell, however, you should NOT breathe it. More Information on Freon Below: (It CAN hav…e an Odor, and is Dangerous in enclosed spaces!) http://www.ehow.com/list_7631527_symptoms-freon-leak.html http://www.dhs.wisconsin.gov/eh/chemfs/fs/Freons.htm http://www.epa.gov/chemfact/f_freon.txt (MORE)
Answer by feather . your freon is measured with gauges hooked up to low side of air condition unit the low side is the cold side high side is the condenser side WATCHOUT high pressure every unit has atag on it and let you know how many ounces to be put in low charge is bad but over charge is also… bad (MORE)
Answer I f u know where to hook it up to which is my problem with the 2001 I can't find the ports to charge mine BUT I believe like other cars I have done IT shold be that u first turn your car on, put the ac on high and the ref. to the port which 9 out of 10 times is blue in coler and check the ma…nufacterer for directions on which way to hold can after u have turned the valve on, keep putting it in till it starts getting cold the compressor will only take so much till its full and it wouldn't go in anymore and don't forget your ac has fuses and relays that can also keep it from working. On the 2001 its a 7.5 amp fuse located under the drvers side dash board. HOPE THIS HELPS!!! Relays under the hood with the other fuses. -------- The charge port is located in front of the passenger side tire under the wheel well. Just turn the wheel all the way to the right and loosen the wheel well and you will see the port there on top of the dryer. (MORE)
It requires special equipment, and legally, a license to handle refrigerants. I'm not being mean. If you are talking about a window AC, you simply can't without having brazing equipment and the skill to use it, plus about $3000 of other equipment to recycle the refrigerant. For a central unit,… if you are low on freon, you have a leak, and that must be fixed. Simply adding freon to a damaged system will accomplish nothing. On cost alone, depending on how much you value AC, you are much better off having AC guys come out. (MORE)
Your heater core has a leak, have the station pressure test your cooling system if it does not hold pressure you a leak in system
Freon, DuPont R22 (Dichlorodifluoromethane) is described in the MSDS as having a "slight ethereal" odor. I cannot say that I have noticed any odor from any systems that I have accidentally dumped. Then, again, I don't stick around to sniff it and I have never dumped a system in an enclosed space. … If you have ever smelled chloroform, it is also described as having an "ethereal" odor. It is best not to sniff that either. (MORE)
Answer . unless you are quialfied to do this, call a repair man, the GAS in a/c units are under HIGH pressure, 350 lbs or more. and you have to have a set of gauges to set it right, theres a high side and a low side,
To know when an air conditioning unit (non-window unit) needs to be charged (needs freon), it will not cool properly or you can test it with the appropriate gauges (see related link below).
What would cause a new 6 month old central ac unit to blow air that smells like sour milk after the unit has been off for a while?
Six months for a central ac is not considered new anymore, far from it. Your supposed to change the filter at least once a month... or your condensation pipe is clogged up.
Freon is odorless because it is a combination of gas and oil.However, many believe it can be detected by a sweet smellingfragrant in the air.
If it has been retro fitted for R-134a with a high effcondenser and a new receiver drier it will take 25 1/2 oz of R-134a, like I said if it has had the retrofit done! If not go some where that can still put in R-12 and avoid black death to your system. Do not even try putting R-134a into a system t…hat has not been retrofitted the compressor is not compatible with R-134a and it will fail! Also it helps to know that when switching to R-134a in that car you will loose around 10% cooling, this can be tweaked by someone who knows what they are doing though.. Also please see my site: http://www.LimuTodd.Originallimu.com (MORE)
It a word, no. Without a leak, the freon level in your unit should stay the same for years and years.
Open the hood, and between the engine and the radiator at the lower point will be a metallic hose with a black dust cap on it, that's the low pressure valve. you should attached the refrigerant in there.
When replacing a compressor in a home AC unit is it standard to replace the freon or is it possible to reuse the existing freon in the new compressor?
When you are replacing a compressor. Chances are that the compressor's internal motor had a burnout when this happens the there is a chemical reaction that makes everything very acidic this in-turn contaminates the refrigerant as well. The old refrigerant would be reclaimed and sent to a a reclamati…on center where it would be incinerated under the guidelines by the Dept of EPA . (MORE)
Change the filter and clean the coil. If it smells like a dead animal clean your duct work.
All HVAC service techs have at one time or another incidentally inhaled refrigerant in the performance of their duties and there are no physical symptoms other than a temporary drying feeling of the eyes that I can recall. If the car you are speaking of is newer than 1993 or so it does not use a CFC… refrigerant, also an automobile`s total refrigerant charge is less than 1 pound whereas the aforementioned HVAC Techs are exposed to equipment containing 1000`s of pounds of refrigerant and experience no ill effects. So I would not worry. (MORE)
First of all if you are asking this you should not be playing with your ac. To answer the question yes you will significantly reduce the life of your ac... as well as cause numerous other problems.
Yes, some of the low end brands are made without a low pressure safety switch and will allow the unit to run until the compressor dies, should the charge leak out.
Although your VW uses refrigerant (one trade name is Freon) in itsA/C system it has no specific "container". It is all a closedsystem, so technically the refrigerant circuit is a container.Could you be more specific?
You can find a Freon leak in a home Ac unit by using a leakdetector. These instruments are capable of detecting trace amountsof Freon and pinpoint leaks.
Freon is odorless. If you're getting a chemical type smell, it's probably anti-freeze leaking from your fridge.
you add the refrigerant in your outside unit but still is going to circulate to your inside unit doing a complete loop
Using a set of a/c gauges put the blue hose on the low side (suction side) and the red hose on the high side (discharge side) to first check the pressures..... Add freon if needed and keep the pressures as follows.. low side readings between 30 to 40psi and the high side between 200 to 250psi d…epending on the outside temperatureâ¦â¦â¦â¦â¦. (MORE)
Since you are aware of what freon smells like , and you must know what it is used for , there is only one system in an auto that uses it.
If it's an auto, there are 2 ports on the lines. One high, one low. Just get a can of r12 & plug into the little valves. Some come with a guage.
My air conditioner sometimes smells like antifreeze and my mechanic did a pressure test to confirm that it wasn't a coolant leak The AC works okay could it be freon?
Try turning the switch to recirculated air or max cool. When you put the switch on just A/C and not max the blower pulls in some fresh air which may be coming from under the hood. The smell could be coming from a heater coil if the heat valve is not shutting off all the way. Or the car could be runn…ing a little hot when the A/C is on. But the antifreeze smell is not freon. The 2 are distinctively differant and probably not being confused. (MORE)
Freon is odorless, but it is possible to smell the refrigerant oil that could also be leaking.
Varmit like a mouse got up in the duct work and died. Wait two weeks, it should go away when the little body decomposes completely.
Any AC, house or car has a pressure switch in the system so that if there is not enough freon in it, the compressor will not come on. The fan will run, but that is all. It is just circulating the air. Nothing will be damaged in the system running it without freon.
Your a/c is recharged through the low side service port with with the blue cap.
Freon R134 is a gas used to charge A/C units. It does not have asmell or color. ...Actually the proper name is not FREONÂ® which is a DuPonttrademark brand of HCFC based refrigerants, like FREONÂ® 22. Theactual R-134a DuPont Brand name is SuvaÂ® 134a... and R-134a DOEShave an odour, it is a di…fficult to detect, "sweet , ether-like"odour. (MORE)
The proper term is actually refrigerant - Freon is a specific brand name trademarked by DuPont for a series of CFC and HFC refrigerants - thus, an AC system only has Freon if it has the product manufactured by DuPont. Answering your question, yes, an outside AC unit uses refrigerant, although it's… normally not the same type used in automotive AC systems. (MORE)
It came with an R-12 system. To determine if it has been converted to an R-134a system look at the ports. If the threads are male then its an R-12 system and if the thread are female then its been converted to an R-134a system
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. (MORE)
Freon is odorless. The oil in the refrigerant system does have a distinct aroma. Freon is odorless. The oil in the refrigerant system does have a distinct aroma.
This normally indicates a refrigerant leak. STOP USING YOUR AC IMMEDIATELY AFTER THE ACKNOWLEDGEMENT OF THIS SMELL!! The fumes from the fluid in your AC system are highly toxic. The leak needs to be sorted out before the AC can be used again.
if you have the ac on to long it starts to stink cause the filter picks up the smell and the smell spreads i suggest you get it cleaned
Google heating and air, followed by the city and state you live in. This should bring up several ac companies in your area.
Well, if the unit was originally meant to be recharged with the old freon, a kit is needed to allow recharge with the new.
It can be done. You probably don't have the qualifications to do it on your own, however. You'll need the services of an HVAC technician, for ease of the conversion, getting it done right, and also for your own safety, as handling refrigerants can be a bit on the risky side.
That's actually lower than most markups. I'm guessing you haveR410a refrigerant, rather than R22 - you'd almost certainly paymore for R22. You can look online and see the cylinders cost considerably lessper pound, but you need to be EPA certified to buy them. With thatprice you pay per pound, you pa…y for the technician's technicalknowledge and experience, and also liability, as well as yourrefrigerant. Compared to what I've been seeing HVAC techs chargefor refrigerant, you actually seem to have gotten a pretty gooddeal. (MORE)
