What You Need to Know about Furnace Short Cycling

As the days continue to cool off, more and more people are going to start to rely on their furnace systems on a day to day basis. Along with that added use comes added stress, which makes it more likely for problems to arise with a furnace. One of those problems is short cycling. Short cycling is perhaps one of the greatest threats that a furnace will ever face. Let’s take a look at what it is, what causes it, and how it can be best dealt with.

What Is Short Cycling?

Short cycling is a behavior in which your furnace keeps turning itself on and off every few minutes. Short cycling is caused by your furnace overheating, typically due to a clogged air filter. This activates the limit switch, which turns the furnace off to protect it from damage and keep the system safe. However, the limit switch doesn’t actually address the source of the overheating. When the furnace turns on again, it overheats again and the cycle continues. This actually subjects the furnace to an incredible amount of strain, making it more likely for the system to experience a full breakdown.

How to Deal with Short Cycling

If you want to prevent short cycling, the best thing to do is to have your furnace air filter cleaned or replaced every few months while the heater is in use. If the air filter is kept clean, it won’t restrict the flow of air and trap heat in the furnace. If your furnace is already short cycling, though, the best thing to do is to turn it off and call for repairs immediately.
