What type of ends are on the condenser and evaporator coils? Will be using a mechanical connection instead of brazing. Are the ends swedge, straight union or flared or something else. Please describe for each 3/8 and each 3/4 inch connection. Thanks This is for Goodman model GLZS4BA3010/AMST 30BU1300

The factory-provided 3/8-inch liquid line and 3/4-inch suction line connections on both the GLZS4BA3010 condenser and AMST30BU1300 evaporator coil are straight copper stubs with plain, un-swaged ends rather than pre-flared or mechanical union fittings, requiring you to add flare adapters or swage them to use mechanical connections instead of brazing.

If you have any further questions, please call us and we will be happy to assist you.
