Why does my heat feel like cold air?

When in defrost mode, a heat pump may blast cold air from its vents for 1 or 2 minutes (before the backup heat kicks in). This forces the outdoor coils to heat up, melting any frost or ice that has built up. And because the heat pump switched to cooling mode, it will blow cold air into your home for a few minutes.
