Does anyone have any experience with the Trane TTL Condensing Unit? Contractor who is proposing tells me that it is made in the same plant in Tyler TX that makes the Trane vertical discharge condensing unit however it is made on a different production line and is hand made rather than on the assembly line.

Does anyone have experience with the TTL ? How is the sound level on the unit compared to a vertical discharge unit? The sound power dbA levels are similiar however i a, wondering if it will be quieter as there is an office directly one floor up in my home. It is replacing a Lennox unit that is 25 years old.

How do you think Trane condensing units and gas furnaces compare to Lennox?
