This has some similarities with our experience for the first 2 years 
with out new Goodman HVAC unit. We heard similar rubbish about 10 degree 
variance, and I was sweating away, with a thermometer showing temp above 
80 in our house.

One symptom was that the blower blew powerfully on heat, and wimpily on 
a/c. On a/c, the compressor ran for a short period of time and cut off. 
It didn't really cut the humidity in the house.

Control sensors were wired wrong, probably at the factory. We gave up on 
the company that installed the unit, and went with another local 
company. We had a long saga with replacing control boards under 
warranty, and then discovering big cracks in heat exchanger. One 
technician listened to my husband describe the difference in air blower 
speeds, and actually tried changing the control wire hookups. He fixed 
the a/c problem. Carlos Colon is the name of this wonderful smart 
technician, and I can't remember which company he works for.

We managed to get Goodman to repay us for some of the labor we had spent 
for 2 years getting repairs to their unit, but did not succeed in 
getting an extended warranty on the heat exchanger or the compressor. 
Units built the year after ours got a recall on the heat exchangers.

My advice is to get someone to check that the sensors and control boards 
are wired correctly.
