Trane Shotty Install-So MANY ISSUES-Awful Customer Service

Due to a shotty installation I have had nothing but issues with my Heat Pump Units, over 12 service calls in 4 years, the install was in 2013. I had a second certified Trane company (alternate from the installer/FORMER service provider) to fix my unit once again that is not cooling, mind you these units are not even 5 years old. The input he provided was sickening and shed a light on the matter greatly, I am infuriated with the installer, (who shall remain nameless for now) and Trane, who allowed such a person to install their product. I will list the matters as it will be easier to list than write a novel on the issues I have had over the past 4 and a half years.

1.My upstairs unit is on its THIRD Compressor, they have swapped it out twice.--To this day it still has additional delays and filters on it that are required to function-Not Normal!

2.Since the install, we have had approximately 12 service calls (WHICH WAS PAID FOR BY MYSELF AFTER YEAR 1!)

 3.The 20XL that I purchased was paired to the incorrect air handler unit and was essentially downgraded below the 20 SEER level that I purchased...SO the INSTALLER Could save money! –the installer talked me into purchasing the top of the line unit to save on my electric bill only to downgrade it, essentially defrauding my household.

4.The new company just brought to my attention that neither of my CleanEffects Air Filters were registered by the installer, nor was the serialized thermostat (which I had to beg the installer to install)(That is now Broken and in need of "Warranty" replacement).

 5.The attic Unit Leaked which I had to insulate to prevent condensation, preventing FURTHER damage to my home...rather than paying for another service call!

If I have had all of these issues (plus some) within the first 4 years, how many more issues will I have when these units are actually old?

All of the issues with my $16,000 systems are because of a poor install. I have provided all corresponding documentation to Trane's "Senior Escalations Specialist" who has, since 23MAR, not done 1 thing to rectify this situation. Furthermore, she has not responded to my last 4 e-mails. Trane has stonewalled me and will not do anything to resolve any of my ongoing issues, they have yet to offer up a single solution. Not to mention the fact that the shotty install is slowly affecting the life-span of my units, decreasing it greatly! I purchased Trane because it was supposed to be the best, to this day I have not experienced anything short of awful. This whole experience has been dreadful, if it is not resolved to my satisfaction I will have no other choice to convey my discontent with everyone I meet and encounter. Strongly suggesting that they avoid Trane like the plague, to avoid the extreme stress and strain that Trane has put on me and my pocketbook. This is NOT what I was purchasing when I bought the "Best".
