Home and Auto AC unit issue

**TrebMaxx** · 10-09-2022, 03:35 PM

For any of the experts with HVAC. I had our 22 year old system replaced, furnace and the outside AC unit in late August. Everything has been good since the switch out. This weekend the late night temps dropped enough to switch over from cool to heat. The furnace came on and the desired temp was reached. As I was working around the house this morning I noticed that my outside AC unit was running. My wife said she noticed it had been running constantly since switching over. This is not a heat pump unit so it should not be running when heat is on. Any suggestions on what would cause this?
