R22 or R410 A

mdmjcc

I need to replace my heatpump and I am trying to decide between R22 and R410.

I have the inside unit in a finished basement. The ceilings are finished. If I change to R410, do I need to change the piping? And if I don't what are the ramifications of keeping what is already there?

Will it last, what would I expect to see in wear?

If I keep R22, how long will it be available?

Simple answer...go with the R-22, by the time it is really phased out there will be another type other than R-410A. Also, the 410a is a smaller molecule and leaks easierand has to be used at higher pressure..

Sorry mate but I completely disagree.

R410a systems are much better, and for the environment as well. As long as your pipe work does not exceed 5/8 the old copper "SHOULD" be fine.


Just remember to have a pro do the job and make sure he fushes the old oil and crap out if the pipe. Don't get dodgy dave refrigeration serives to do the job.


R22 is a HCFC and is nasty to the environment. The next phase of refrigerants you'll see coming on the market will be CO2. In 6 yrs time cola-cola amital will only use merchandisers which run on CO2.

I disagree about being able to use the same piping because the pressures run almost two times as high on the r-410a I install units & I always go with a thicker wall pipe when converting to 410. The low side pressures run approximately 119 psi. on 410 compared to 69 psi on the R-22 systems. Thats a big difference.
