No matter how cold it gets, your heater will not run continuously. Instead, it operates in cycles, turning on for a stretch of time until your home is warm, and then shutting off to rest while the temperature coasts slowly downward, until it gets cool enough for the heat to come on again. These cycles should last somewhere between ten and twenty minutes.
What if your heating system is cycling on and off very quickly? When your heat comes on, shuts off in a minute or two, and tries to come on again moments later, that’s called short cycling. Don’t let it continue! Here’s why.
