Update to 3 stars since the owner came actually pretty fast after my one star review and was very knowledgeable about all the system, not like the previous young representative. he could make the fan function running. I waited until winter tune up to see how the winter maintenance will go and I was impressed with David's work and experience. He was very friendly I didn't mind all my questions about what he was doing. Thank you David. After about I guess 9 months having the Trane systems installed we saved decent amount on air-conditioning, don't see big difference in heating. So if you know what you want to have installed make sure you check model numbers when they arrive for installation! After installation no one seems to be interested about the mistakes they have done.

I'm very disappointed with this company. When Erik came first to my house he was very professional and explained to me everything what I asked about. On May the 7th two trane systems have been installed with the new S8X1 instead of XT80 (in their estimate) furnaces and everything looked fine. Then I noticed that there is nearly no airflow when system set to circulate or fan on. David came to check on this and he was surprised that the new furnaces have only one speed option on the blower motor for the fan mode and that is the first one, which makes the fan option not useful at all. He sad that they installed about 30 of those units so far. I couldn't believe that they didn't know about this issue. This is not acceptable for me since I use the fan circulate or on when needed.
They only solution was to install relay on the new furnaces so the fan can run on a/c fan speed when in fan mode. But I need to sign a document saying they are not responsible for mold due to running the fan without the ac! I refused to sign any documents and they never got back to me since then!
So if you are looking for system that will work properly in all three settings COOL, HEAT and FAN stay away from the S8X1 furnace and this company because they don't take any responsibilities for their work and systems installed and let you hang after you pay!
Not even mentioning that they installed a bigger coil than I wanted without letting me know. I found this out next day from model numbers. They didn't pull a permit as agreed with Erik. David send techs back to install one more smoke detector and connector for exhaust pipe(needed by code). And they forgot again to install the pipe connector. Hope they really send the rebate forms to city of Austin so I can get compensate at least a little until I find out how to deal with this furnace and this company.
