Sorry, this product has no FAQs.
When I turn on my gas furnace cool air blows out of the vents for the first couple of minutes.
Your thermostat may be configured for an electric furnace. When configured for an electric furnace the fan comes on immediately when there is a call for heat. Gas furnaces need a couple minutes of warm up time before the fan runs. Please see the "installation" section of your owner's manual for information on how to properly set your gas/electric fan option. All manuals are available on this website.
When I turn on my heating system (furnace) it takes a couple minutes for any heat to come out of the vents.
Most gas furnaces have a short warm up period before the fan will come on and circulate the warm air throughout your ductwork. This is to prevent cool air from blowing at initial startup and is not controlled by the thermostat.
