My furnace keeps the house warm but it does cycle often. It will start and then shut down and then about five seconds later it starts and runs fine. I have a small house that is insulated decent so I know it shouldn't cycle as much as it does(at least five times an hour) does this affect my gas bill? How do I make it cycle less. Oh like I said it is a very small one bed house but it only has two cold air returns one that's in my bedroom on the ground and the other is just an open vent into the basement which is unfinished and usaually cooler does this affect anything?
