During the winter season, we’d all rather be listening for sleigh bells in the snow instead of strange sounds coming from the furnace. While there’s no such thing as a furnace that is completely silent, a clicking sound is certainly something to pay attention to.
There are perfectly normal clicking noises that are common among heat pumps that are a part of the system as it begins a cycle or shuts itself down. This clicking, which comes from components as they engage and disengage, isn’t typically a problem but there are situations where it can be a cause for concern.
