There was a discrepancy with the thermostat

The thermostat seems to be mistaken, plus I now have another method of what I am going to do about it, and I think that there is no way that the thermostat can actually be accurate.

I wonder what my comfortable temperature is.

I consistently think the most comfortable in my house when the thermostat is set to around 68 degrees, however my partner prefers the temperature to be around 68, plus I am fantastic with that. I consistently think a little warm, although I can live with those uneven temperatures, but however, recently, I began to notice that my house has felt a lot colder, and for instance, I walked into my house 1 afternoon, plus I had to put a jacket on because it was so cold. I decided to check the thermostat, plus it said that the temperature in the house was 73 degrees. I think for a fact that this is not accurate. For the next few days, the thermostat said the same thing, although I knew that it was colder. I have no way to verify this, although I am pretty sure that my thermostat is broken. I don’t mind that it is broken, although I hope that my central air cooler isn’t running occasionally. I might need to call an actual heating and air conditioning specialist plus see if they can verify my thoughts. If I need to buy a thermostat just so that I can get an accurate reading of my heating and air conditioning unit, I could totally do that. I have just never heard of a thermostat doing that before. Has anyone here ever experienced anything similar?
