Hi. I just had some equipment installed and I'm having issues I'm hoping you all can shed some light on. The equipment is as follows: compressor GSXC180361BB (Goodman communicating 18 seer 2-speed 3 ton, Goodman 3 ton 17" evaporator coil), furnace GM9S80 (Goodman 80% 60k BTU single stage gas furnace 17 1/2 wide).
I opted to keep my Ecobee 3 thermostat bc it has sensors in each room rather than just in the hallway. The installers told me that although they were not re-wiring the ecobee to operate as 2-stage, the compressor will know when stage 2 is called for based on the temp requested. That sounds fishy to me, bc I'm not aware of Ecobee sending any information to the controller in the compressor. It is possible to set up ecobee as 2-stage and it will determine when to request stage 2 but they said that was not necessary.
Here's what is happening: on day of installation the temp in the house got up to 78. The thermostat was requesting 72, so more than 5 degrees diff. It ran for four hours and came down one degree and 1 percent humidity. No problem--needs to get things under control, but I suspected it was not running at 100% capacity.
Two days later (today, Sat 6/11) the temp in the house has leveled out. This morning the humidity was 61% and temp 74. I turned the temp to 73 and the unit started. The unit has been running ever since and the temp is now 77 and humidity 71%. (It's Atlanta 86 degrees outside at 1:38pm.)
I don't think the unit is running in stage 2 and I think there is something wrong with the evaporator. Any ideas? TYIA
