I have had three service calls this summer related to the Air Conditioning not working. During the first call (May) it was determined there was no refrigerant in the unit. After performing a pressure test no leak could found and the unit was filled and in working condition.
In August, there was no cold air coming from the unit. Once again there was no refrigerant and it was found there was a leak in the outside 'radiator' (I do not remember the actual name for this part). It was replaced and filled once more with refrigerant and the unit was functional. The second technician noticed a black oily patch where the refrigerant was leaking.
In September I experienced no cold air coming from the registers in the house. In fact there was no air at all being circulated by the furnace. This time the furnace controller board was replaced because the issue is intermittent.
My rating is based because a repeat service call had to be placed for the first failure (No First time fix). Both of these two service calls meant that I had a 4 hour window in which the service technician would arrive and then he would have to actually diagnose/resolve the issue. The first call essentially took the better part of a day. The second call also took a large amount of a day for the technician to arrive (4 hour windows)and to determine the cause being the radiator. Another day was required for the replacement of the radiator because the part had to be ordered and the repair had to be rescheduled.
The third service call was very similar in the controller board was not available after being determined that it was the most likely problem (this is an intermittent problem). This meant scheduling another service call on a different day for the replacement.
In summary, I had three service calls and it took 5 service calls to resolve the issues meaning 5 days of my summer was used up to fix the issues.
On another note, twice I left messages when placing a call to have someone call me back and I never received a call back. I had to follow up the next day with a second call to actually schedule a service window.
I also have issues with quality of the products (Trane) since these units were installed in 2012 and were purchased through Direct Energy now known as Enercare. The units were the best quality products sold at the time and I chose them because they were suppose to be reliable! My experience has proven otherwise....
