Gas furnaces always run on heating cycles. Each cycle is the time from when the furnace turns on until the thermostat registers the correct temperature and signals the furnace to shut off. If you ever notice that your furnace is running for a much shorter or longer time than normal, it indicates there is some issue preventing your heating system from working correctly. With that in mind, here is a quick overview of the average length of a furnace’s heating cycle and also what it means if your furnace is cycling on and off too slowly or too quickly.

That being said, there are a few different factors that can affect either the length of each cycle or how many cycles the furnace has per hour. Outdoor temperature is obviously one of the biggest factors since this will affect both how quickly your home cools down and how much heat is needed to bring the temperature back up.
