furnace started blowing air that is colder than it should be. On my normal setting(23.5 degrees C) it blows VERY cold air but when I crank it up to 28 degrees or so its blows my normal air. When I looked at the furnace the flame looked normal, and the pipes leading out of the unit were hot. The outside temperature right now is around -26 degrees + windchill. Any ideas why this is happening?
is it just a furnace or is it ac too, or a heat pump? you may want to call a pro before it gets too cold.
Provide some return air / supply air temps for us.
How old a furnace?
Single stage or multiple stage heating?
Oil, NG, or propane fuel?
What is its Input & output Btuh?
Got any idea what the airflow CFM of the central blower is?
Last time I checked -26'C /
