My 2 cents worth about R22 versus R410a

I am not an expert -- so perhaps my comments make no sense at all; however, I hear many HVAC people talk about they do not mess with 410a yet -- keep R22. Well, I think I understand that R22 will be around for a long time (no problem with that).

On the other side. It is almost 2006. Beginning in just 4 years, HVAC dealers that want to put in any new units better get comfortable with R410a. Perhaps R410a is not as good as R22 that can be debated but there are going to be many, many units using R410 in the year 2010 and beyond. Heck, there are many units now using R410a. I teach computer courses at a small university -- things change all the time in my world. Many times I am not in favor of the change but you have to get up to speed with new technology or the times pass you by.

Not to flame anybody, but the future of Heat Pumps from my view (good or bad) is R410a. If a HVAC installer does not feel comfortable with it or trained or have the equipment then it seems like they better get comfortable with it in the next couple of years or they will only be able to service old equipment not install any new ones.

holy cow, and here I thought 40 degrees was 40 degrees.

It's amazing how people make this stuff up.

 

humidity removal? Never had or heard of that before. I kind of look at it like this. some guys don't like putting in R410 yet. A lot of differences in it.
R 410 cannot be evacuated to remove water it has to be filtered out.
410 is a LOT higher pressure.
R410 is same cost to put in, if it leaks though its higher priced by WOW ITS HIGHER PRICED!!!
takes different equipment and some guys don't wanna put out the expense to change over yet.
Champaine leaks in coils in southern climates with R410
etc etc. Its your choice. as far as humidity removal? I wouldn't give that a second thought.

 

OK, I looked...

Rheem RAMC36 R22 with matching TXV coil .72
Rheem RAMM36 R410a with matching TXV coil .72

A-S 2A7A4036 R22 with matching VS TXV air handler .74
A-S 4A7A4036 R410a with matching VS TXV air handler .76
oops, R410a isn't doing too well here

York H1RD036 R22 with matching TXV coil .72
York CZB036 R410a with matching TXV coil .74
OK, so the R410a falls a little behind at York

Amana RCC036 R22 with matching TXV coil .78
don't use that in a humid climate
Amana RSC036 R410a with matching piston coil .72
gee, piston does better!

Bottom line, as I said before, check the units you desire regardless of refrigerant

 

If you are concerned about it, look at the exact specs for the outdoor unit, coil & blower you are considering.

 

There's no consensus,that R22 dehmidifies better.

 

I have an Infinity system with the R410a and it does a fabulous job of removing humidity. It keeps my home around 45%-47% and because of this we have been able to raise the temp to 77 and it is still very comfortable.
