A furnace in your home should cycle from 2 to 3 times in an hour depending on how cold it is outside and how insulated your home is.
If your home is not insulated properly and your home leaks air and lets cold inside and hot air outside or when it's very cold outside the furnace may cycle 4 to 6 times per hour.
Getting your home insulated properly, sealing up air leaks and even installing new windows that are insulated can help keep the heat inside where it belongs and allow your furnace to work less and save you money on fuel heating bills.
