Hi my aircon light keeps flashing off amd on and thats all it does it was fine untill i took it down from my shop and then 2 weeks later insatlled it in my house all the wiring is installed correctly could it be that the gas leaked all out when i took the pipes off
Before you disconnected you should have pumped the system down, keeping all of the gas in to the outdoor unit. when you reinstalled you needed to vac the pipework then open the outdoor unit valves to let the refrigerant through. if you had disconnected the pipework without doing this you would have lost the gas, so yes a recharge will be required. hope this helps.

Sounds like the compressor is failing or seized (for the air con). This would put extra pressure on the system. It could be another fault with the air con system like the solenoids not opening up to allow the flow of gas in the system.
Does the sound stop after a minute or two? IF so, this is normal. When the a/c is working, there is high pressure on one side of the expansion valve, and low pressure on the other. When you turn the a/c off, the pressures equalize. That's the noise you are hearing.
There is a specification plate on the base of the unit. It will have the refrigerant type and quantity listed. The leak should be found and repaired before re-charging with refrigerant. 1993 model could be r-12,r-22 or r-134a.
It could be a part called the Idle control Valve. It regulates the Idle speed and keeps it smooth. If it is choked up with carbon gum or the little motor inside it is faulty then it will not allow enough air too pass for smooth idle. When you put your air con on the engine is under more load because it has too turn the aircon pump so it will stall. Also you have a little device on aircon cars that raise the idle a little to compensate for the extra aircon load. If this is not working it could be that.
More than likely it is the remote sensor in the indoor unit. Then again I presume that it is the correct remote control. Sometimes a remote for one aircon may not communicate with another aircon even if they are the same brand.
Di he put a tracer dye,usualy green,in when he recharged the aircon?It will usualy show a leak pretty quick,You may have a pressure safety switch thats faulty,usualy screwed into the aircon pump on the high pressure side and if it senses a low pressure problem it shuts the air con down to protect itself.It will have two wires running to it and joining the two wires will reactivate the aircon.Not advisable to leave wired up in this way as the air con charge also lubricates the pump and running it dry will require pump replacement if left running too long.Cant help with air con specialist as im in australia Good luck
You say that the air con is not cold, i think the problem would be the aircon will need regasing, if the gas has escaped from the system, the temperature in the aircon system will always be warm so the fan will continue working attempting to cool it down. It will need checking for leaks, most companies that recharge the system check the whole system for leaks first before refilling the system. If its the engine cooling fan it could be the thermo switch that is faulty,the way to check that is when the engine is cold disconnect the wires from the switch and put an ohms meter across the swith it sould not give any reading, it will only show a reading when the engine reaches operating temparature. hope that helps. regards Richard
