Furnace is on continuously but nothing is turned on

Not sure if this is normal. My furnace is running continuously, producing small Amount of cool air (only in the boiler room). no air in vent. The fan is not on nor is the flame. The ac is turned off as well as the heat. Is this normal for the furnace to be on? The only time it turned off if I completely shut off the switch but that only last for several minutes before it would come on again.

Could it be that we have two water heaters attached to it?

I have a Coleman p*xu /g9d (up flow) 60-120 mbh input. Less than 5 years old

Welcome to the forums.

It is very hard to tell what could be running if you shut everything off.

You turn the switch off and it stops and then turns itself on again.

A picture or two posted here of what you think is running since I have no idea would be most helpful.

Sounds like thermally controlled fan switch and hot weather?

What is "running" if there's no fan, no flame and no AC? You say it's a little cool in the boiler room but the fan isn't running--do you mean then that the AC unit outside (only) is running continuously?

Edit--nevermind--just noticed the age of the initial post.
