Converting R22 systems to R410A

Koppertone

I read a articular that was posted about converting system from R22 to R410A .Where they talking about replacing the meting device in the air handler or the evaporator coil & if so, where did they find a device for 410A? Also how much changes has there been from R22 systems to the
R410A systems, 3 phase 208\230 volt ?

They're using a R410A condenser. the indoor metering device is what ever size piston the condenser calls for, or a R410A TXV. Voltage is what ever the building has. R410A units come in the same voltages as R22 condensers did.

Thanks for the feed back. Can I purchase a metering device & make my own conversion?

yes. Done fairly often.
