We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

   If the frost buildup on the coils is so thick that it looks like they are encased in a block of solid ice, then the system is not turning on the defrost cycle as necessary. This will decrease the efficiency of the heat pump and possibly damage the equipment, and means the unit requires service. At the other extreme, if the system is switching to defrost mode every few minutes, it would also indicate that the system needs repair.

   But the accumulation of a thin layer of frost/ice, and the subsequent defrost cycle, is a normal for a heat pump during the winter months--especially during the several nights each year when the temperature in Gainesville dips down to around 20º F and we have a “hard freeze.”

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
