To put the long story short, my 13-year old National system-3 air conditioner went up the lorry a few days ago. At the moment, my family is looking to replace it with a brand new system-3. Are there any recommended service provider to install, replace the old air conditioner and install the wooden board/plank that covers the wall that leads to the compressor? I am looking at Mitsubishi or Panasonic System-3 inverter at the moment. The current wooden cover is already disintegrating. One last thing, is CoolServe recommended?
