It is definitely not OK. The temperature in the house should be within one degree or so to the thermostat setting. The first thing I would do is to verify the actual temperature with another thermometer. Then turn down the thermostat to 80 degrees and see if the AC unit comes on. Also, check the breaker to see if it is tripped and check the condensate drain line to see if it is clogged.
If the house is less than 5 years old, the HVAC system should still be under warranty. If it is a Carrier Unit, you can write down the model number and the serial number from the inside air handler unit. Then, go to the Carrier warranty website and it will tell you the exact status of the warranty.
