We live in Central Texas where temperatures stay in the 90's for half the year and are mild for most of the winter. Our current 4 ton York unit is 12 years old and starting to fail (freon leaks in the coil among other things).
We have had several different estimates for a new installation from local companies that vary considerably - all for units from different manufacturers. Though Carrier seems to be the most recommended brand online, none of these companies offer Carrier.
Instead we have been offered Trane, Amana and Fridgidaire. Amana is the cheapest, Trane much more expensive. Has anyone had experience with new installation of these brands in the past few years?
Is Trane worth the extra money for a similar SEER rating?
What other questions do you feel are most important to ask the installers?
Thanks,
Murk
