I have an evap coil in a home, maybe 5 years old, and I need to convert to 410. Coil is spotless, looks like it was just installed. My goal would be to add a TXV and use same coil, but I cant find any info on that coil's rating. Just a name, model number is scratched, somewhat unreadable. International Comfort Products, Model # EPA....something. No serial number.
What is the average pressure with 410 vs 22?
