In our previous blog post, we talked about how often and for how long a furnace should cycle on and off. We also dove into some reasons that could cause your furnace to go off this schedule. A common problem that plagues older furnaces, or even improperly installed furnaces, is a process called short-cycling.
Short-cycling is when your furnace, or air conditioner, cycles on, runs for a very short period of time (think 5 minutes instead of the preferable 15), and shuts back off for a few minutes, only to cycle back on yet again. During this time, your furnace is never completing a full heating cycle.
