I have a new home that is nearly completed. The AC Company is ready for their final draw, but I am concerned that the system is not working properly.
Home Size: 6200 sqft
System - Trane XL19i Heat pump 5-ton (lower-1), 4-ton(upper-1), and 3-ton(lower-2) / c variable speed air handler.
To test the system I set all 3 to 68 degrees. The house was 85 downstairs, and 84 upstairs prior to the test beginning @ 9:30am. Outside Temp was 85.
10:35am - Outside 86, Temp 78 in house
12:22p - Outside 92, Temp 75 in house
2:15p - Outside 92, Temp 72 in house
4:11p - Outside 95, Temp 72 in house
6:30p - Outside 95, Temp 70 in house
To compare, I went to my current home @ 2:30p, went to my master bedroom, temp was 83. I changed the thermo to 68, and at 3:45, it was 68. This is a trane XL14i 2 ton unit (NOT HEATPUMP)
I believe I have a problem, but I don't know what basis to complain about other than this just isn't right. I mentioned to the tech on Friday that it wasn't coolling proper, and he checked pressure (very quickly) and said it is normal, and new systems need to break in. I feel that is BS, so I am hoping someone with a little knowledge might tell me a smart question I can ask.
