Hi I'm new here, base on my experiences as an aircon tech, the best brand that can last longer on the compressors is Sanyo, National, Panasonic. We all know National brand was taken over by Panasonic. I will definitely recommend a Panasonic brand for air con and fridge. As for Sanyo the compressor is the best and can last you at least more than 5yrs but the cooling fan coil design is a bit noisy. Mitsubishi uses Panasonic compressors in their unit but the electronics in my opinion can't last long. The more complicated the design, the more problem u will meet in the future. So my recommendation for aircon is 1st: Panasonic, 2nd: Sanyo, 3rd: Mitsubishi. As for fridge u won't go wrong with either Panasonic or Mitsubishi.
