I did a google search and came up with this:
An orifice (also referred to as a piston or flowrater) is installed in an evaporator coil when the coil is a different tonnage rating than the condenser or heat pump tonnage rating. Installation takes about 5 minutes, and consists of replacing orifice already inside coil. We have an online picture step-by-step guide which shows how to do this.
If you are installing a new evaporator coil and can not find manufacturer-specific information for your outdoor air conditioner or heat pump, use this chart as a reference to ensure a properly sized orifice is installed in your system.
R-22 R-410A
Tonnage Orifice Size Orifice Size
1.5 Ton 0.053 0.047
2 Ton 0.059 0.053
2.5 Ton 0.071 0.059
3 Ton 0.076 0.071
3.5 Ton 0.080 0.076
4 Ton 0.082 0.080
5 Ton 0.090 0.090
Now, I know for a fact he told me I was getting a 5 ton coil for a 5 ton compressor. He mentioned the two diff sizes needed because my system still runs 22. above it says that there are different orifice sizes for different refrigerants.
