Thread: R-22 or Puron

  1. #1
    Looking to replace my existing 3 ton Ruud unit. Installed in 1989, it's seen better days. It was a high efficiency unit back then!

    I have a buddy in the HVAC industry and we trade work for work. He has quoted me two similar systems at his cost. The first is a Carrier 38YRA036-3 with a FK4CNF005000 variable speed air handler. This is the R-22 unit.

    According to Carrier's product data sheet, matching this AH with a 42-31 unit gets a 14 seer with a 12.10 eer and a seasonal efficiency of 8.20 but their ratings don't show the exact combination quoted. They do show a FK4NCNF003 that will get 13 seer, 11.25 and 8.0.

    The second unit is a Carrier 38YXA036-3 with a FX4BNF036000 variable speed hair handler. This is the Puron unit. According to Carrier's own product data sheet, matching this AH with this units gets a 13 seer with a 10.75 eer and a seasonal efficiency of 8.5.

    The R-22 unit is only a couple of hundred dollars less than the Puron unit and on the surface looks to be more efficient. Which is the better unit and why?

    What does your "buddy" think about it?

    Of course the decision is mine, his suggestion is to go with the R-22 solution. He believes that even with the phase out of R-22 and even with the scare tactics of the industry as to how much R-22 will cost (when compared with the same R-12 situation *the sky is falling*), that R-22 service will still be affordable and drop-ins will be available.

    On the other hand he believes that Puron is more efficient. The numbers just don't show it and spending a couple of hundred dollars more for Puron equipment when both have similar warranty's just doesn't make 'cents'.

    So I come here asking for more advice from the experts.

    The manufacturers are pushing "Puron" or it's generic equal R410A, since they have no choice in the future, and the quicker that they can run one version only in production, the cheaper and better it is for them.

    Puron (R410A) has a greater cooling capacity than R22, which can be an advantage in equipment size, but it operates at 50% to 70% higher pressures than R22. The higher pressures require systems to be "beefed up" for strength. Some feel that the higher pressures are more likely to develop leaks and other failures, but a well designed and installed system should be no different than an R22.

    The choice today is really moot. R22 will be available for a long, long time, and it's new equipment phase out should not be a factor in which to buy. If you are a hard core environmentalist and think you might develop a leak in the unit during it's lifetime, that would be a decision factor.

    I would still stick with R22 today, only because it is a well proven, mature technology.

    We have installed over 2000 Puron/R410a systems,since 1997,it's a proven product,IMHO.

    check out http://www.410a.com for more info..

    Puron is nothing more than Carrier's name for R410a. R410a is actually AZ-20, made by Honeywell (aka)Allied Signal. R410a is a much better product than R22. And even though R22 will still be available after 2010, the equipment won't. I would choose the R410a system, you'll be happy with it.

    Puron has no determining factor in size of equipment.

    If your house requires 3 tons, with a r22 system, then it'll need 3 tons with a puron system.

    We haven't installed as many as Dash, but we have no troubles with them either.

    Puron (r-410a) is good, but unfortunetly Carriers Evaporator coils arent so good, IMHO. So if you are getting a Carrier, go with R22, the indoor coil will handle the pressures better. Maybe Im just mad at Carrier right now, but I feel that way. If you want 410a with some other brand, then go for it.

    Puron. Go Puron. But don't choose Carrier/Bryant.

    Is that FX AHU part of the new "communicating" system?

    What does the guy who is installing this equipment for you install the most of? Puron, aka R410a, requires greater attention to good installation practices. The system MUST be clean, and MUST be moisture free. Now that should be he same for an R22 unit, but an R22 unit is more "forgiving" than R410a. This is where experiance comes in. If he has a lot of R410a installs under his belt, you should be safe with R410a. If he has only installed a couple, go with what he knows best, R22. Another thing to remember, unless this guy can give you a waranty, and thats not likely if this is a side job for him, you are more limited on who can work successfully on R410a than R22. Something to think about if you have to pay warranty labor.

    My question is quite simple: Why don't you trust your "buddy's" recommendation? You are trusting him to install your system that you hope to have up and running for many years to come, and I assume provide you with service as well. If that is who is going to bear that responsibility to the system and to YOU, then HIS recommendations and opinions are really the only ones that matter. Just curious as to what 'work' you trade to him for his hvac expertise. IF you trust your buddy, then our opinions are secondary to his. IF you aren't 100% sure about his recommendations, then call a qualified contractor and have them do all the is proper and necessary, i.e. calculate a load, look at your air distribution system, etc. Seem like a lot? Yeah, it may seem that way, but if, and I emphasize IF a mistake was made 14 - 15 years ago in capacity, etc., then simply replacing with same unit will only duplicate the mistake made then, and not give you the efficiency you desire.
    Everyone has a purpose in life..........even if it's to be a bad example.

    Seek first to understand, before seeking to be understood.

    FE is the Infinity air handler.


    FX isn't variable speed but the FK is,so if you go with Puron,go with a FE or at least a FV ,both are are variable speed.
