04) wire cutters
05) pliers
06) a refrigeration compressor
07) a condenser (can be fabricated)
08) capillary tube
09) 20-40' of 1/4" OD copper tube (used for evaporator and condenser if it needs to be fabricated)
10) shrader access valves (at least 2 possibly 5)
11) 1/4" copper sleeves OR 1-2" of 3/8" copper tube
12 )REFRIGERANTS R-134A, R290 are common use because they don’t require you to be licensed to get them
