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
If it's blowing cold air right after it fires up, it's just the cold air that's already inside the ducts, kind of like cold water in your hot water pipes.
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.
The humidifier may be telling it to blow. The thermostat may do it to sample the air or the furnace may have a 'stir' setting.
Auto is off. Auto Makes fan come on with call of heat or cool. Check to see if you have a air circulation timer mounted on your furnace.
