What do I do if there is ice on the outdoor AC unit?

Ice on the outdoor unit is normal. A properly operating heat pump will develop frost and ice as part of its normal operation.

Note: Outdoor unit may have ice.

A heat pump will defrost periodically to melt the ice that has built up on the outdoor coil surface.

Warning: During the defrost cycle a heat pump may produce unusual noises and produce large quantities of steam. Do not be alarmed. This is part of a normal defrost cycle and will only last about 15 minutes.
