Had a new unit installed in March 2017. Have had nothing but trouble. Company comes out, cleans drain, acts up again a short while later. Tired of spending money on this thing. Company came recently and installed new valve. Still does not work. Company came today, cleaned drain, still doesn't work. We think the unit is a lemon, but have no recourse but to call and pay until the summer is over. We are both retired Ingersoll Rand employees and were sold on the American Standard brand. Not anymore. The company that installed is Summit Services Heating and Air, 86 Beach City Road, Hilton Head SC 29926. [protected]. We are reaching out to get some sort of satisfaction. I recently thought about trashing this thing and buying something else. Things like this reflect badly on TRANE and American Standard and rest assured we will let others know about our issues. We would appreciate at least a confirmation of receipt of our complaint. Thank you.
