What is the range between your low side and high side when working with R410A?

Question

Ex. R22 60-70psi low 200-250psi high

Answer 1

Hello Daniel:

You can roughly double your pressure readings for R22 to give you your pressure range for 410a. You will want a gauge set designed for 410a, with shutoff fittings in addition to low-loss fittings on the hoses. Be sure that you NEVER mix the oil from 22 to 410a.

Answer 2

Around 110-140 on the low side and around 250-400 on the high side.

Quite different pressures from R22 so higher pressure gauge manifold and hoses are required.

EPA certification is also required for someone to work with refrigerants.
