We have had no problems with the builder installed (2013 vintage) Carrier HVAC system, and we have never had the emergency heat come on. I am not an HVAC expert and I do not have any equipment to check the system, so I would suggest having the system checked again.
One other thought, if your temperature change is large enough this may be causing the emergency heat to come on. We keep the temp more or less the same between night and day, and just use a fan if it is too warm at night.
