The defrost cycle of a heat pump system is crucial to maintaining its optimal performance and for ensuring the longevity of your heating and cooling investment.
When a heat pump is performing in its heat cycle it is typically doing so in the cooler winter months. When the ambient air temperature outside of your home is cool and the relative humidity is high, it can carry more water vapor than normal. This set ups a condition wherein frost might form on the surface of the much colder outdoor coil. If left unattended, this frost covering will interfere with the optimal operation of the heat pump, which costs you money. To correct this occurrence, the auto defrost cycle on your heat pump becomes activated to remove the frost.Details
