Moving Air Conditioner

If you want to relocate your air conditioner. Process changes according to season.

How to store air conditioner gas

Air Conditioning Pipe Valves
Air Conditioning Pipe Valves

In winter,

  • Run ac on heating mode 10 minutes for stabilization of gas
  • Close the valve of large copper pipe. It works as gas pressing line during heating mode. This line is hotter than thin copper pipe line.
  • In closed position, wait 75 seconds to store gas inside compressor. Voice of compressor will change, when gas is stored inside it.
  • Close thin copper pipe valve.
  • Close air conditioner.
  • Close fuse of ac system.

In summer,

  • Run ac on cooling mode 10 minutes for stabilization of gas
  • Close the valve of thin copper pipe. It works as gas pressing line during cooling mode. This line is cooler than large copper pipe line.
  • In closed position, wait 75 seconds to store gas inside compressor. Voice of compressor will change, when gas is stored inside it.
  • Close large copper pipe valve.
  • Close air conditioner.
  • Close fuse of ac system.

Tips: In winter If you touch temperature sensor with your hand, you can run ac system in cooling mode. In summer, if you touch with a cold material to temperature sensor, you can run ac system in heating mode. I achieved best gas storage in heating mode.

Air Conditioner Disassembly

  • Take photos of electric cables to record connection.
  • Record Phase , Notr, and Ground cables of fuse to reinstall it in new place.
  • Remove all electric cables of inner and outer ac system.
  • In copper pipes, there is small amount of gas. Unscrew, copper pipes slowly. Wait 15 seconds, to allow gas discharge. If it takes more time, you couldn't achieve gas storage perfectly.
  • Unscrew pipes, and remove pipes.
  • Remove water pipe.
  • Remove legs of air conditioner from wall.

How to Fix Air Conditioner to New Place

  • For fitting of inner and outer ac systems to wall, select place that allows air flow.
  • Join copper pipes, electric cable, and water pipe. Then wrap with tape. By this way, you can easly bend your copper pipes without damage.
  • Clear faces of valves and copper pipes by hand. Also, you can use vacuum cleaner. Connect faces of copper pipes to valves. Keeping this position, tighten the nuts of copper pipes. If you don't keep pipes stable, it causes leakage of gas.
  • Connect electric cables.
  • Open valves of thin and large copper pipes slowly. You can hear gas flow inside pipes.
  • Check your pipe connections. If gas leakage exists, tighten the nuts.
  • Run your ac system.
  • After 5 minutes, again check your connections. If gas leakage exists, store your gas inside condenser.
  • Untie nuts. Check faces of your pipes. Clear them and reconnect again. Again open valves and run your ac system.

Air Conditioner Troubleshouting

  • If countersink of copper pipes is damaged, cut pipe and make a new countersink.
  • During cooling mode, If thin copper pipe is covered with snow that means ac system has insufficient/low gas.
  • During cooling mode, If large copper pipe is covered with snow that means ac system has excessive gas.
  • If ac system displayer/screen doesn't work, check fuse, earth leakage circuit breaker, and power supplier card.
  • If ac system displayer shows Error codes, look ac system instruction manual for error code. Generally, you can meet temperature sensor error. Check your temperature sensor connection cable. Check temperature sensor resistance by touching on it. You must see resistance changes.   
  • If fan or compressor of outer ac system (condenser) doesn't start, check capacitor.
  • If you can't activate heating mode, you probably have problem with four-way valve. If you decide to change your four way valve, becareful for plastic parts during soldering process.
  • To test performance of your air conditioner each year, run system 10 minutes for stabilization,  measure input and output air temperature and measure current of ac system. If your parameters lower than normal mode, you can increase performance of ac system by cleaning it and charging gas.
