Ac is running fine freon etc all good to go.
Furnace and ac running at same time.
I looked at the thermostat and it was set to 72 the room temp was 79.
I m no expert but i m pretty sure that isn t supposed to happen.
So i checked on the a c and it was running.
Plenty of people have had the same thing happen and it is an easy fix.
You need to scroll through the menu on your thermostat and set the fan to auto.
It sounds like it is programed to either high or low.
Brand new furnace i replaced last winter.
I just turned the a c on for the first time this year and i noticed that my house was not cooling.
I felt the air coming out of the register and it was warm.
The ac kicks on and starts blowing cold air and about 2 min later the furnace ignites and the all the fresh aced air becomes hot.
Next i checked on the furnace it was also running.
Air conditioners and furnaces how do they work together.
