Why does a R410A condenser work on a R22 evaporator coil?
Why Does a r410a Condenser work on a R22 evaporator coil? Both refrigerants, R22 and r410a work off of pressures. Mor specifically they work off of a balanced ratio of vapor and liquid pressures. Though these two refrigerants need different pressure they both use incrementally similar pressure ratios.
Can I use R410A instead of R22?
No, you cannot. To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures. R410A is a higher pressure system and R22 is a lower pressure system.
Does your new air conditioner use R-22 refrigerant?
The new air conditioners now use R-410A refrigerant which is much more energy efficient and doesn’t impact the ozone as much. However, many people can’t replace their air conditioner unit even though they may want to. Often they will look for another option. One option is to retrofit your R-22 refrigerant system with a R-410a refrigerant system.
Are You having Compressor burnout problems with R-410A HVACR systems?
By Robert Scaringe, P.E., Many contractors are experiencing compressor burnout problems with R-410A HVACR systems soon after they’re converted from R-22 refrigerant. A conversion should always include condenser, evaporator, and line-set change-outs, but the problem lies in the fact that linesets can’t always be changed out.
Can you use a 410A condenser with R-22 evaporator?
Can I use an R410A condenser with an R22 air handler? No, you cannot. To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures.
Can I replace a R-22 condenser with a R-410A condenser?
No. You can't do that. It probably wouldn't work. Even though you put a compressor in there that's R410A, the rest of condenser probably isn't tested and rated for operating at R410A pressures because R410A has to operate at a higher pressure.
Are evaporator coils interchangeable?
Most manufacturers specify that if you replace either the evaporator coil or condenser coil, it must be the same size (and SEER rating). Otherwise, they'll void any remaining time on the warranty. This is because manufacturers specifically design both coils to work synergistically.
What happens if you put R-22 in a 410A system?
If you use R-22 in the same system as R-410a, the compressor is going to be trying to work two different fluids through the same coils as both refrigerants respond differently to different mechanical situations. As you might imagine, this isn't going to go well for your air conditioner or heat pump.
How do I retrofit R22 to R410A?
Converting an R-22 system to R-410A is like converting a diesel engine to run on gasoline; it can't be done without making major changes to the entire system. In the case of HVAC systems, conversion requires replacing the R-22 compressor, evaporator and condenser with units designed to run with R-410A.
Are R22 evaporator coils still available?
On January 1, 2010, the Environmental Protection Agency (EPA) implemented a ban on the production and import of R22, except for continuing servicing needs of existing equipment. The EPA also banned the manufacture and installation of new R22 AC or heat pump systems.
Can you mix and match HVAC systems?
While it is recommended to buy the same brand for your HVAC systems, a furnace and an air conditioner manufactured by two different companies can usually still work together.

And if there's an older one you can blow it out with nitrogen.
Can you put a 2.5 ton condenser with a 2 ton coil?
In spite of the nay sayers here yes you can and it can work very well. You will indeed have to install an expansion valve that matches the condenser capacity. It also depends on the type of evaporator coil and furnace or Air Handler that you have.
What refrigerant is compatible with 410A?
R-32The leading replacement for R-410A refrigerant is a pure, single component refrigerant called R-32, which has one-third the global warming potential of R‑410A. Some products with this next generation refrigerant have already been introduced in the United States.
What Freon replaces 410A?
R-32Daikin has announced R-32 as the ideal choice to replace R-410A in the Americas and around the world for many of its key products. Carrier has announced its intention to use R-32 for scroll chillers and R-454B for other residential and commercial products.
Which refrigerants can be mixed?
The most commonly mixed refrigerants in the field are the replacements for R-22 — R-427A, R-438A, R-422D, and R-407C — which are often combined with the remaining R-22 in the system, said Maiorana.
What does R22 and R410A work on?
Both refrigerants, R22 and r410a work off of pressures. Mor specifically they work off of a balanced ratio of vapor and liquid pressures. Though these two refrigerants need different pressure they both use incrementally similar pressure ratios. The other factor that you may hear some HVAC technicians say is the Evaporative coil can not handle ...
How long does a R22 condenser last?
A tech could do a poor job of installing the R22 condenser and the unit would last for 10 years or more. With r410a units, the installers must have there process dialed in tight. No more sweep charging or fast flush. Each system must be vacuumed down to 350 – 700 microns. The Las Vegas dry climate makes this easy on most summer days.
Does a 410A have a warranty?
If you have a 410a condenser installed on your home and you have a home warranty it is unlikely that they will make any further repairs to your system. On the other hand, If you are looking at installing a new condenser, they may have already given you the boot. If you purchase a new condenser for your home you can rest assured that the manufactures 5 to 10 year parts warranty and Fast Affordable Air’s 1 to 3 year labor warranty has you covered.
Can you crosscontaminate a R22 to a 410A?
Based on a 9 year history of this practice and 2 dozen plus warehouse test mutts, we know conclusively that there is no more risk of cross-contamination from R22 to the new 410a with a condenser only change out than if you were changing the evap coil too.
Does a 410A condenser last longer?
There is no reason to believe that the 410a condenser only install will have more problems, be less effective at cooling or will not last as long with or with out a matched coil.
Does 410A evap coil have a larger surface area?
The 410a evap coil has about a 30% larger surface area than it’s R22 counter part. Does that make it 30% less efficient when paired with a 410a condenser? We don’t think so but we are pretty sure that you are not getting the full 14 SEER value by installing only the condenser. Customers did report that month over month and year over year that they saved $30 to $50 over there old condenser while others said it reflected no electrical use savings at all.
Can a R22 counter be replaced?
The answer is an undeniable and indisputable yes. Though you may hear several opinions to the contrary, we know from experience that it will cool equally as well as the old unit. When tuned properly, it will produce at least as cold of air as the R22 counter part being replaced.
What pressure should an R-22 coil run?
An R-410a coil, conversely, at the same conditions will run at 130 PSI. Almost double the pressure. At first glance this looks concerning. But remember, R-22 coils are typically tested to 300-400 PSI, which is a much higher pressure than R-410a will ever run on the low side. You should never use an R-22 evaporator coil with an R-410a outdoor unit ...
Can you use an R-22 coil with an R-410A?
You should never use an R-22 evaporator coil with an R-410a outdoor unit if the outdoor unit is a HEAT PUMP. You should never reuse an R-22 evaporator coil if tin and antimony were used in the brazing process. By the way, if you find a coil like this it will be ancient.
How old is an air conditioner?
30 years is very old for an air conditioner. Chances are very high that it would need to be replaced. You could potentially replace only the condenser and keep the air handler, but it might be worth your while in terms of efficiency simply to change out the whole system.
Can you replace an R-22 with a compatible refrigerant?
Most R-22 replacements are not going to be supported by the equipment warranty. If you have equipment still under warranty, using the replacement would void it. And you can't add to the R-22 with most of these. You would need to evacuate the R-22 entirely, and replace it with the compatible refrigerant.
Can you convert R22 to R410A?
If you're going to convert from R22 to R410A refrigerant, the best thing to do would be to flush the lines you have, and put in units, an air handler and condenser that is meant to use R410A. R410A and R-22 are just so different that doing stuff like you want to do won't really work.
Can a R410A compressor work?
It probably wouldn't work. Even though you put a compressor in there that's R410A, the rest of condenser probably isn't tested and rated for operating at R410A pressures because R410A has to operate at a higher pressure. So, the coil is probably not tested for that and it would probably fail.
Can refrigerant lines be flushed?
Some installers mention that lines can be flushed/cleaned while others mention that refrigerant lines have to be replaced... Check the lines themselves. If the lines are in good condition and are the correct size for the new units, they can be flushed and reused.
Can you use a R410A condenser with a R410A?
Yes, if the coils you have are rated for R 410A, they can be used with an R410A condenser. However, the metering device will have to be changed to one suitable for R410A, and it would be advisable to flush the coil to remove as much R22 refrigerant oil as possible. Richard. Posted on 3/15/2021.
What is R-22 refrigerant?
R-22 refrigerant leaves behind a mineral oil and other contaminants. The entire system must be cleaned and this will include the filter driers, the condenser, and evaporator. Essentially, all of the components the refrigerant travels through will need to be flushed and cleaned.
What refrigerant does an air conditioner use?
However, good news came from it. The new air conditioners now use R-410A refrigerant which is much more energy efficient and doesn’t impact the ozone as much.
How far should a refrigerant line be?
For the R-410A refrigerant system, the line must be between 25 to 50 feet in total distance. Additionally, the line must be flushed and cleaned out.
Does an air conditioner run on R-22?
Uncategorized No Comments. Many homeowners that learn their air conditioner runs on R-22 refrigerant fears the day their unit develops a refrigerant leak. R-22 has been phased out and new air conditioners run on the new R-410A refrigerant which is much more environmentally friendly.
What is the difference between R22 and R410A?
R22 coils are made from copper which are more likely to leak refrigerant than the R410a coil. Your particular unit is a heat pump and because of the reversed refrigeration process where high pressure is exposed to the evaporator coil (which does not happen in an air conditioner) you have a greater chance of coil failure.
Is 410 air handler rated for R-22?
Some older air handlers will say they are rated for both, some say R-22 only. 410 runs at a higher pressure than R-22 so you have an older unit that may or may not have built to take a higher pressure. Also the lines sets have to prepared correctly or replaced so there are a lot of things that could wrong. btoye (Bradley Toye, CMI) February 6, ...
Can an evap coil take 410 pressure?
The evap coil may not be rated to take the pressure of 410. Even if they made it work, its not a matched system so it will never work as designed. Its just a scab of a system, installed by a scab of a contractor. mpagozalski (Mike Pagozalski, CMI) February 7, 2018, 4:24pm #11.
Is R410A compatible with R22?
Condensing unit (R410A) and evaporator coil (R22) are labeled for different refrigerant types and may not be compatible with each other. Recommend verification with the manufacturer or qualified HVAC contractor whether these two units are compatible and replace components as necessary. Not sure who thought it was a wise decision to stick ...
Can you boil a CFC refrigerant?
It won’t boil off , even if the system is under a vacuum for days or weeks. Cleaning the lines of these contaminants requires a flushing solution. In the old days, before CFC refrigerants were banned, service technicians used R-11 to flush lines. New EPA regulations prohibit this practice.
Can you flush a jug with a vaporizer?
To ensure complete removal of the flushing compound, it too, must vaporize. Therefore, any un-pressurized liquid flushing solution from a jug is totally unacceptable, since it’s just trading the oil and other non-evaporating fluids in the system with another liquid impurity that also won’t evaporate.
Can you flush refrigerant oil down the drain?
Toxic non-biodegradable flushing agents can’t lawfully be disposed with waste refrigerant oil, can’t simply be flushed down a drain, and might require the disposal methods equal to those of hazardous materials status. Additionally, refrigerant oil recyclers may refuse refrigerant oil with hazardous materials.
Can refrigerant oil be blown through a compressor?
Flushing agents are excellent for removing oil from linesets, but at the same time they should never be blown through a compressor because it will remove oil from the compressor and it will seize up.
Can a supers05 coil be used with a 13 seer condenser?
supers05. A coil designed for use with a less than 13 seer condenser should not be used with a modern unit. Click to expand... While it'll drop efficiency, and there's no good reason to save the old coil, it will work.
Can you put an R-22 on a R-410A?
The evaporator must be rated for R-410A, and the metering device must be changed to the appropriate R-410A size/type.#N#Because he does it all the time, might mean he does the wrong thing over and over.#N#You can absolutely put an R-22 condenser on an R-4 10A coil. It’s done all the time for customers with le aking coils that don’t want to change the R-22 condenser yet. As before the right metering device must be used.#N#This information excludes heat pumps, which have to be matched correctly or they will not operate as they should. In some cases you’d have to pay a tech to come add refrigerant to use the heat and remove refrigerant to use cooling.
