Why does my new furnace high efficient Payne furnace blow cold air,not constantly but at least 3 different times in a day, my thermastat is set on auto but when the weather is cold outside it will still blow cold air thru out the house how do I turn this off ,is there an option ? Or do I need to buy a new thermastat that has an off switch for the fan instead of what I have an / on/auto switch Only
I had a similar furnace. I am going to assume that this is the normal cycling, throughout the day, where the controller is giving air movement throughout the house for comfort reasons. It's controlled by a variable speed motor on the fan by your thermostat, I think.
If the air is too cold, you should talk to your installer and ask them about that. I recall that sometimes the air did feel a touch cool (in my former home) but it's been a while. I just wasn't used to the circulation and wound up setting my temperature a degree warmer than usual.
