We just got a new system installed. It is all electric. When the furnace runs you can hear the thermostat click to end the cycle. It continues to run to force all the warm air out of the ducts. Good. The problem is, using incorrect but understandable terms, there is 1 gallon of warm air in the ducts. The fan blows long enough to push 5 gallons of air out. Those last 4 gallons of air are cold air from the attic, as if the a/c was running. Is it possible, and if so how, to adjust the timer controlling fan shutoff after the heating element is shut off?
All these new units run off a circuit board. Call the installing company. It is likely a simple pin change at the circuit board. Maybe micro swithes, depending on brand, but it is adjustable at the air handler.
You do want some time delay there but it is usually adjustable at the circuit board.
