R22 or R410 A
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..
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.
