First off i live in Fla and i have a 3200 sf home about 14 years old that has 2 zones. I had a Trane rep come to my home and advised me that i need to have my old American Standard replaced with a Trane XLI 19I 5 ton condenser and a 2tee3c65a 5 ton v/s communicating air handler. He told me this unit would be better and cheaper than going with 2 units because of the 2 compressor system in the XLI 19I.
When the installers arrived they informed me that the current zone system was not compatible with the new system. The owner brought a Honeywell EMM-3U universal minizone panel and 4 dampers at no charge since they should of noticed that it was not compatible during the quote process.
Here comes the bad part. I was quoted a price for the condenser,air handler,2 XL900 thermostats,and new refrigerant piping. After they installed the thermostats i had noticed they were XL800 not the communicating XL900. When i told him that they were the wrong ones he told me that they could not use the XL900 thermostats because they were not compatible with the Honeywell zone system. Is this true? I can not see the the reason to have a condenser and a air handler that are supposed to communicate with each other if you can not have the thermostat that is to communicate also.
They did not replace my lines and to top it off they installed a 2tee3f65a non communicating air handler. Can anyone help me with the thermostat issue or if it will harm the unit by not having the lines replaced?
Thanks in advance.
