said by pandora:The heat pump doesn't circulate cold refrigerant to the air handler when defrosting. The heat pump fan also stops blowing. The coils get hot. I have seen this, as we had a glass viewer on the refrigerant line to the air handler when looking for air bubbles. No refrigerant moves out of the compressor during defrost.
This would seem to magically work differently then every other heat pump out there. The current 18 SEER unit on Goodman's website also doesn't seem to have any type of heater in it's
