One of the most common troubles that homeowners run into with their heating during the winter is a furnace that keeps turning on and off rapidly, going through what’s known as “short-cycling.”
The standard heating cycle for a furnace is at least 15 minutes and often not much longer than 20. This is the amount of time necessary for the furnace’s components to work together to heat air, send it through the ventilation system, and raise the home’s temperature to the target on the thermostat.
When a furnace starts to cut short its heating cycle and then restarts a short time later, it creates a problem that affects home comfort, energy consumption, and the amount of wear and tear on the furnace. If you’ve got this problem with your furnace, you’ll want it corrected as soon as possible. We’ll look at why this may happen and what you can do about it.
