Can I Use R410A and R22 Refrigerant Together? - Ask the Expert Episode 115

hi , please tell me i replaced my 1,5 t outside unit with 2 t and is frozen,why? Thx Ryan

I love how you so humorously get straight to the point. Even with your making a short story long. Lol

I have an R22 Condesor and air-handler. My condensor needs to be replaced and the HVAC company I used basically said the same as what you're saying in that the I would have to replace the air-handler also because of the pressure difference between the R22 and 410. However, I spoke with a company called choicerefrigerants (choicerefrigerants.com) and they tell me that their 410 condensor can work with our existing R22 air-handler. What I was told and what their website says with regards to their condensor working with existing R22... "has nearly identical pressures to R22, allows for flexibility to pair with existing R22 interior coil and air-handlers" ... is this bogus or seriously not recommended?

Can I mix 401 with 407c freon

A man claimed to change ac to inverter n change its gas into r410a instead of r22 .is it true sir ?

What is the operating pressure of R410A ?

Can you evacuate a r22 central air unit and refill with r134a

I am using R22 in a R410a 1.5 ton split system, and it is working somehow.Can you tell what will be most effective pressure in that case for r22? I am using it at 85 psi.

I have a carrier infinity tm 19 heat pump with puron. It resantly started low stage lock out.(4hours) the repair man cant explain why. Recomends replaceing the unit. It is 13 years old. Can you explain what causes the lock out and is it fixable.

The compressor in our 13 year old 3-ton Lennox R22 AC condenser is broken. We have 3 options on the table...what would you pick? A. Repair the compressor with a well known company for $4500, but know that R22 refrigerant is expensive ($110/lb and ours takes 6lbs) and scarce for any potential future problems. Can't get any additional repair quotes from other companies unless I pay for a service visit - that's what all companies are saying. B. Replace the entire unit (condenser and air handler) with a lesser known company for $6800 (Rheem brand, 410A) and they can do it next week C. Replace the entire unit (condenser and air handler) with a well known company for ~10k (Bosch heat pump system or Lennox AC 410A) and it could take anywhere from 2-4 weeks. Is there a 4th option? Is it possible to just replace the outdoor condenser with a 410A that's not a heat pump if the air handler is fine?

I have an old unit. It blowa good air but not cold. What could be wrong with it

We only run our old system maybe 10 times a year. It IS old though (about 30 yrs). It got hot here in CA recently and when I turned on the A/C the outside unit turned on and a few seconds later turned off again. It now does that constantly - never on for more than a few seconds and then off for a few seconds. I had someone check it out and they say the pressure is low and this means there has bee a leak of freon. Because the old freon is tough to get (and very expensive) he recommended replacing the whole system and has quoted me $17,500 for a 5 ton unit for our 3,000 sq ft home. When I went online to check pricing of complete systems Including the furnace it looks like the hardware should only be around $4,000 Any advice? The old system was working fine before this on-off thing started.

Kyle..you should try some of the stuff i try...loosen up man. everything i work on is out of warranty anyway..its fixable junk. so a recently did a true commercial freezer repair. used a r-22 scroll to replace a Hermetic 404a in the end i replaced the gas with a very limited shot of 410a into a fresh vacuumed system the results were fantastic..-20 in the freezer. the system is a cap tube system so no txv is involved the compressor never heats above lukewarm. there is no reason for 410 to mix with the oil or send the oil higher in the system. its Poe. its designed to saty in the compressor. all designed pressures on all systems is rated at 550lbs even a r-12 9the blow valves are rated at 550 on r12.......and as a second safety device thermal overloads and super heats all kick in before any ruptures. (i find people who say 410 will blow up everything hilarious). 410 runs at about 280-290 psi area. complete changeable gas with r-22-404-407 yes i am a old uaw man.....i build a lot of stuff.. and most of my stuff lasts longer than the manufactures who school the kids all wrong info... .032 wall copper can even do 550lbs.

I have a unit that used r22. It had a leak and the tech put 401 in it. That leaked out. Can I go back to r22( found some) without it messing the unit up?Will it affect the expansion valve?

I have 2 AC units, one unit (downstairs) needs replacement. They’re both old systems using R22. If the broken unit is replaced with a newer model using (R410 system) will that work (1 R22/1- R410) or do both systems need to be relaxed and why?

Sir i am Bangladeshi , but working middle east ,pls sir u tell me r22 gas air-condition , what i can refill r410 , same pressure if i will put same pressure r22 .any problem.

Question: We have an 40 yr. old furnace with similar age a/c condenser. We are replacing the furnace to include an evaporator coil. We do not plan to use the old a/c with the new coil. Can we install a new condenser to the evaporator coil at a later time if we haven't operated the old condenser? Thank you for taking my question

We have a unit that needs a charge every year or so. It was charged in January and at the time the technician offered to put a sealant in it but didn't have any. Another technician from the same company finally came 2 months later and put the sealant in. Three weeks later the unit quit cooling. He determined it needed a new coil and told me it would be very expensive due to the R22 refrigerant. However, today I noted the tag said R410. Could the compressor failure be due to putting the wrong coolant in it (if he did) or the sealant. It's a Goodman unit circa 2009. We also got a quote from the same company for a new Trane unit (we bought one from them last year) and the quote was $!600 higher than last year. :-( I am getting competitive quotes.

Can I use an R410 evaporator system to combine an r22 condenser system?

Pls i want you to put me through on this, how can I discharge the old gas in my ac compressor?

I accidentally put some R22 into my split mini and, so far, the two cats are doing just fine?

The question was not about mixing refrigerants the question was about all R22 or all 410A a compressor compressor has a condenser condenses the only difference between R22 and 410A systems is 410A has better compressors and more evaporator and condensing coil space

I have an old air conditioner. I just had it cleaned and check; according to service man it should be at 58, it’s at 56. It use R 22. Cost to refill with that is 424.99. Can I have another type; R4226 orR 407c

Hi all, here every one is sharing such knowledge, so it's fastidious to read this website, and I used to visit this website every day.

I thought the cats analogy was clever and to the point, without having to diagram complex carbon bonds.

My r22 compressor went out. It was made in 2002. My evap coil is 410 and was installed 2012. The guy wants to get a 410 condenser and reuse my r22 in the system. Will this work?

The question on this topic was can I use a 410A condensing unit with his R-22 air handler., it can be done bye recovering the 410 out of the condensing unit, and changing the high and low pressure switches to operate for an R22 pressure, and use r407c refrigerant. I have done this multiple times with no issues. Second question I seen was to use R22 back in a 410 unit, that would be no, due to the fact of the 410 unit is p o e oil, R22 uses mineral oil.

I guess I'm lost with the cat story... were the medical charges for repairing the damage to your son more than the cost of a new HVAC system?

Hello. I would like to upgrade my A/C unit from R22 to 410A. Can I just replace my Copeland CR28K6-PFV-230 to a compressor that will handle 410A. I was going to dump the oil out and upgrade that as well. Is there a compressor conversion for doing this?

My inside r22 unit went out , my outside r22 unit is good , the guy insalled a 410a unit inside an flushed it , change the pressure vale an filled it back with r22 freon , not it seats really bad an is running on my floor ,! Wats my problem ?? Thanks terry

how can you determine what pressure you need to use when refilling a room ac r410a

I have a Out unit that uses 410 a my coil is leaking in my handler. I found a coil that uses R 22 can I use this coil

I have a split geothermal system the main unit for the lower level and basement uses r22 and the attic unit uses 410a . Shouldn’t they be the same?

Is there any other refridgerant besides R22 that can be used to top off an R22 unit?

I accidentally mix r410a with r22 can I vac it down and put back r22 with no issues

Hi! I’m looking out for my father who accidentally put R-410A refrigerant in a R22 System. He only put some in until realizing what he did. The air conditioner no longer runs and we need to get the gas sucked out in the next two days. Nobody is available to take the gas out for us. Is there a way we can do it ourselves?

What can I mix with R22 freon in my home system?? I only need to add a pound or 2 to top it off!!

could you please suggest a good link that explains how to correctly recharge or top off an R600a refrigerator. thanx. john

I believe everyone to use full of crap nobody can come up with a layman’s terms you always have to put in stupid words that don’t mean anything It’s all about money

Hi I have a small question about R134a Is it possible to put in the vehicle R410a instead of R134a Thanks

company put 410 a coil in split system 22r 0ne year ago compressor not cool[ng because of lower 22r pressure what should be done

I'm trying to cut big pieces of copper I'm thinking is there any type of solution spray to place on the copper like freon to freeze it and hit it to crumble or break into pieces... Thank u

But please I have a big problem, help me. My LG air conditioner carries r20 which r22 was manufactured to replace and the r20 is not in existence and no way to be found. What should I do. My plan was to flush the condenser then fill in r22 refrigerant.

Hi Dan, What refrigerant is best for a dehumidifier & which one will prolong the appliances life span ?? R134a or R410a. I heard one runs cooler than the other & prolongs the life of the dehumidifier !! Is that true? If you had to buy a new dehumidifier which refrigerant would you choose for longevity ?? Thanks

I have a 2002 Monaco Windsor motorhome.My 15000 BTU air conditioner compressor locked up. It was working fine until that happened. Is there a compressor that I can use to replace this one with? The Complete air conditioner is over $1,500. I am certified and able to service most air conditioners. I have enough R22 to service the system after repair.

I work as a maintenance man in a homeless shelter and one of my AC units is low of freon. This one calls for R-422b and all my other units take R-401. Is R-401 compatible with R-422b?

I'm just curious you say not to blend refrigerants, but yet espouse refrigerants 407 404 410a when you get into the science of these they are manufacture blended gases. the back yard guys can do just as good as the manufacture by blending gases....the manufacture guys build stuff to fail at 5 year mark roughly 2 years after the warranty. I do agree r-410a and the new 1234 stuff are extreme pressures....they are good gases but the pressures cause compressor failure no matter who builds it. the best gas out there for the cheepo's is 134a.....it has low pressure but only 60% the cooling ability of 410a......134a will do the job. 134a takes 40% it takes longer to do the same work as 410a but the pump lasts longer because of the lower pressures. for the other gasses r-22 replacement some suggest r-290 or propane....this may not be legal in America but it sure is in Europe. 290 is really cold stuff, and the pump last longer with 290. in my opinion i haven't found much difference between Poe oil verse Pve oils mixing....as long as the evap fan cools the compressor you should not have oil failure. also what ive found is hype about 410 going into systems not designed for 410.......if your smart you can downsize the amount of 410 going into a system not designed for the gas. you just have to use the PT chart and temp of the day and fiddle with the filling ounces to stay inside your rated pressures you'll be fine. after all we all did the changeover from r-12 to 134a........we did the same thing...the suggested filling ounces was not what we used to refill a system. Just was wondering what your thought are....about backyard guys.....we cant do any worse than the manufactured crap.....their stuff fails constantly right out of the box.

IS THERE A FREON THAT WILL MIX WITH R22
