Answer:

i'm assuming you're utilising organic gas, propane or heating oil. if so, examine your pilot gentle. If this is not igniting, the unit gained't come on. have you ever had your thermostat replace presently? if so, it ought to were stressed out incorrectly.
Mine does the same in fact it will blow heat and then cold air till the thermometer kicks the heat on again. I am watching for logical answers to this one thanks for asking
That's a good brand. Probably the reason is the duct work has to heat up also and it will take a few minutes for it to become as warm as the air coming through it.
Understanding your forced-air furnace During normal operation, the burner on the furnace starts up, warming the heat exchanger and the air in and around the heat exchanger. When the air is warm, a fan control starts the fan to distribute the warm air into your home. This delay is built in so the fan does not start immediately and blow cold air on your feet. When the room air near the thermostat is warmed to the set point, the thermostat turns the burner off. The fan continues to run until it has removed the heat from the heat exchanger. When the heat exchanger is cool, the fan limit control turns the fan off. Hope this helps!
