My house has a Trane XL19i that actually has two separate compressors a low and high. The low compressor runs when when the room is within 1 to 2 degrees of desired temperature on the thermostat. The high compressor kicks on to get temperature down quickly or is 3 or more degrees outside of what is set on the thermostat. Problem I’m running into, when talking to Micro-Air, is they say they support 2 stage A/C units but it seems at least the guy that spoke to me at Micro-Air is that if your unit has two compressors it won’t work. I’m attaching pictures of my AC unit along with the inside to see if maybe anybody has any ideas or can point me in the right direction.
