Since purchased less than three years ago, my trane XL16i air conditioner has been nothing but trouble. It hasn’t run a year without something breaking, and me stuck waiting days or weeks (in Florida, in the summer) for replacement parts to come in.
This last time it broke - the problem is far worse because the dealer that does the warranty work can’t seem to fix it after half a dozen tech visits, over a month’s time.
The AC’s running nonstop since the evaporator coil was changed, yet fails to adequately cool off the house and won't get anywhere near the thermostat setting of 74 that worked just fine with the old (leaking) coil. Since then freon was added (overcharged) or removed, and the TXV valve replaced after the service manager said he thinks that may fix what's wrong. These repairs led to a new issue of water dripping down the outside of the air handler, onto the wood base. When I changed the air filter it was soaking wet. The dealer doesn't know what's wrong. It took two weeks for the new coil to arrive, and another two weeks for two (the first was defective out of the box) TXV valves. Now what?
I opened a trouble ticket with Trane, but they brushed me off by referring me to the regional rep whom after leaving a few voicemails, hasn't returned any calls.
I read two multi-paged threads here with similar trouble, but neither got resolved.
I'm worried about mold in the ducts and other heath troubles. What can I do about that while waiting for Trane to do something with the broke AC?
