Recently replaced a 5T 13 year old Rheem AC with a Carrier 5T 16 seer heat pump. All seems working well, but electric bills are same. I have 3 areas of concern and two questions to follow.
- Install instructions specify 1 1/8 vapor tube for a 25 foot run. I have a 35 foot run and they used the 7/8 tubing in place.
- Evaporator coil (attic, horizontal unit) was turned around and installed backwards. They told me Carrier only made a left hand unit and it is ok to reverse it. Took them two additional trips to stop leaking throught filter.
- They force fed the Carrier air handler into the old Rheem plenum which is 40% smaller (pic attached.) It's like 60% of the air hits a vertical wall, then must recirculate back to flow into plenum.
First question is how much efficiency am I losing because of the 3 concerns listed above.
Second question is the long term effect on the wear and tear of the unit.
