Brandnew Trane XL16i failing HELP

[jamierenae]

Ok so i just purchase a brandnew Trane Unit Xl16i with a Airhandler TAM7A00
TAM7A0C48 Hyperion™ XL Series 7 plus with the XL803 Thermostat
we spend almost $ on this unit in December 2011

i have a single family home one story approx 2280 sqft.
I had asked for a load calculation when i bought the unit but the sales rep ensured me he knew what he was doing.

Unit ran fine UNTIL about 1 month ago. It first started it would try to come on and kept clicking in the thermostat. so they came out and replaced that. Unit ran fine for a bout 1 week. Then the outdoor unit, which i was told is one of the quietest out there started to be really loud when shutting off. almost like something was stuck in the blade of fan. Then last week i came home saturday at 5 pm and mind you i have my thermostat programmed to come on every day at 5 pm to be at 77 F and when i leave i have it set to 78 F I came home to 83 F in my home!!!

Tech came back out and said needs a NEW compressor!!!! mind you again unit is ONLY 5 month old!!!
That was about 1 week ago they installed new compressor.... and dryer.

Yesterday same thing happens again... set to come on when i return to 77 come back at 5 pm its 83 F in my home. I left at 1 pm. so somewhere between and 5 pm the unit is NOT running BUT it does come back on at around 7-8 pm on both days..... MAYBE it can't handle the HOT HEAT during ***** this is one of the reasons we purchased a new unit because our old unit RAN 24/7..... and now this one wont run at all during day... so YESTERDAY tech came back out and told us a cable was lose and the tech might have hit a PLUG! ....... well again last night and all day today until i left around 1 pm again unit was running fine.... so i come back home at 5 pm again AGAIN 83 F...... i shut unit off and tried to turn it back on NOTHING.... again around 7:15 pm UNIT came back on!!!!

What is going **** OBVIOUSLY they can't figure it out. Should I ask them to give me a brandnew **** I feel so uncomfortable to start off with such a LEMON!!!!!

And mind you this is a company that gets all the sales from HOME DEPOT you would think they know what they are doing!!!!

I called their after hour service right at 5 pm and i JUST now got a return call and they said maybe they can send someone out tomorrow. What to do if they can't figure out whats going * Do you think it's an installation issue or a PRODUCT ****

Any suggestions would greatly be appreciated
