"Amcor is out of business," I was told. There is no warranty.
Oct. 2010 I purchased and installed a 9000 Btu unit one year ago. The compressor had to be replaced due to a leak. Amcor sent a replacement at no expense, however this new compressor was noisy right from the start. Now, 12 months later, it has died with an apparent electrical short.
The wall mountable thermostat is useless as it does not keep accurate time.
A frustrating characteristic is its failure to maintain a constant temperature. It regularly cools colder than called for or heats too much.
I bought Amcor for the low price and good specs. If I wanted to buy another mini-split, I would look for another brand.
Oct. 1, 2011. Last year my outdoor unit (the compressor unit) developed a short. Pridiom had no interest in honoring the earlier warranty. I finally fixed the short by replacing a bridge rectifier on the power board. ($3.75) The heat pump is working fine now, I'm glad to have it back.
