Hi All, I have just installed two new CM 3ton systems. One is a TE038 the other is a TES038, I also have an older 4 ton CM Tranquility 22. My question relates to the performance difference between the TE038 and the TES038. For some reason, the TE038 is doing a better job when the TES038 when I compare EAT vs LAT in both stage 1 and stage 2. For example, the TE038 is giving me a consistent 26-degree increase (69 EAT, 95 LAT) when I measure at the unit, whereas the TES038 can only manage a 20-degree increase (71 EAT, 91 LAT). All measurements are taken with the same equipment over the course of several days. All units are on the same closed loop. The only major difference is that TES038 air handler is in the attic, and the TE038 is in the basement. The EWT/LWT is 41.5/35 for the TOS038 and 40.7/33.7 for the TE038. Does anyone have any idea why the TES038 isn't doing as well as the TE038?
