(1)My Trane A/C unit, installed new 8/2012 by Total Tech LLC, did not work when turned on @ the end of 5/2013. I called Total Tech LLC for a yearly service @ informed A/C down; 5/31/2013 Total Tech LLC performed the routine yearly service & found that a 20 amp circuit breaker had tripped. I paid for the service call $95.40. (2)During the week of 7/7/2013, the A/C unit went down. The technician found that the system was "freezing-up" & needed to replace the "TXV" part, did not have it & was ordered from Texas; it arrived a week later, but the technician discovered that it was an incorrect part for the unit & would have to re-order a correct TXV. I didn't want to wait another week, so Total Tech LLC was able to locate the part in Beckley, WV, had it driven to Frankford, WV, (3) & installed the correct TXV part. Late that afternoon, the 20 amp circuit breaker tripped again, & I called the owner of Total Tech LLC, @ 5:00pm to get the technician back. (4)When he arrived at 6:15pm, he could not find anything wrong with the unit but said that he would be back on Tuesday, 7/22/2013 to replace the circuit breaker. I called Total Tech LLC on 7/22/2013 & the owner said "We think you need to get someone else." This system is under a ten (10) year warranty (parts and labor). The technician never came back, and I was billed $159.00 for after-hours overtime of one hour, and the system is still not working. (5)Well I did get "someone else" today, and the first problem noticed by the new air conditioning company was that the A/C unit was pulling 22 amps from a 20 amp circuit breaker causing the breaker to trip, which should have been addressed when the new unit was installed in 2012 by Total Tech LLC. So the new company installed a new 30 amp circuit breaker supplied by me; also found that the new "TXV sensing bulb" was incorrectly mounted by Total Tech LLC. The new company re-mounted & insulated the TXV; system working properly. read more
