What to do with surplus AC compressors?

[lowkey]

I have 3 R12 compressors here given by a family friend. Working naman daw yung compressors and in good condition. May magkaka-interes ba bilhin mga ito? How much can I sell them? How can I check the compressor kung ok pa?

i-offer mo sa a/c repair shops pero malamang babaratin ka lang. They can have it tested too. Ipinaplug dun sa pressure gauge nila while the compressor is rotated by an electric motor. Magpoproduce dapat ito ng pressure.

singit lang po sa tanong, me difference ba ang R12 compressor sa R134a comp? i mean, can't i use the same compressor for both freon ?

Benta mo sa mga off-roaders. They can be converted into on-board air compressors. Useful for airing up tires and stuff.
