I purchased a new home in Sep. or 2005 with 3 AC units. In September of 07, it was determined that one of the evaporator coils was leaking so itw as replaced under warranty. In January of this year, a second unit had the same problem, and while outside of the mft. labor warranty, I was told that there had been a high occorence rate of this problem so they would cover both parts and labor under warranty. Now, Yesterday, I'm told that the compressor associated with the first unit to have the evaporator coil replaced is apparently burned out. All this after only 2 1/2 years. I called the mfg. and they said they would review this with management. I'm trying to pull some facts together, but from what I've read, it seems like running the unit with low refrigerant and having the compressor short cycle on/off for who knows how long before we realized the problem, this all would contribute to undue wear and tear and contributed to the burn out. Does this sound logical to any of you experts?
Thanks for any/all help.
