Can R22 equipment be retrofitted to use R-410A?

R-410A should never be used in a system designed for use with R-22. Equipment originally designed for use with R22 is not constructed or tested to withstand the higher operating pressures of R-410A. System components including the compressor, condenser, system piping, etc., must withstand not only the higher operating pressures of R-410A, but much higher burst test requirements as well. Many...
