Why does my central unit blow cold air first then warm while set to heat?
When your central air conditioning unit is set to heat, it first blows cold air because the system is working to cool the warm air in the ductwork and unit itself. Once the system is able to cool the ductwork, the warm air from the furnace will begin to flow through the vents, providing heat to your home. The amount of time it takes for your system to begin blowing warm air will vary depending on the size of your home, the outdoor temperature, and the efficiency of your system.
