Why my a/c compressor stopped coming on after I put Freon in

Hello, air conditioning repairs require proper diagnostic testing to determine the cause of actual malfunction. Honestly speaking, it is environmentally reckless to just "put a can in" -- because you are not properly inspecting the system to ensure our environment is not going to be continually contaminated by refrigerant that escapes into the atmosphere due to a continued leak. Handling refrigerants requires a legal certification through recognized by the Environmental Protection Agency. Automotive professionals engage in proper training to protect our environment from hazardous refrigerant gases. All that said: you haven't done a bit of testing on your Odyssey and you are adding refrigerant. What if the system has a blockage and will automatically spike high pressure and vent off everything you add into the atmosphere? What if the system is charged properly, but the compressor or coil is not working? What if the inside controls are the actual problem and the under hood components were good in the first place -- and now you're potentially causing damage by adding unnecessary refrigerant? I strongly recommend a professional evaluate your system legally and safely. Good luck.
