You need to scroll through the menu on your thermostat and set the fan to auto.
Furnace and ac running at same time.
Ac is running fine freon etc all good to go.
Ac and furnace run at the same time.
Air conditioners and furnaces how do they work together.
Next i checked on the furnace it was also running.
I felt the air coming out of the register and it was warm.
Furnace heats the air in the winter and the blower circulates air through the home ac evaporator coil removes heat and humidity in summer.
I looked at the thermostat and it was set to 72 the room temp was 79.
It sounds like it is programed to either high or low.
I m no expert but i m pretty sure that isn t supposed to happen.
Plenty of people have had the same thing happen and it is an easy fix.
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.
So i checked on the a c and it was running.
