When our modern gas furnace was installed the two of us were amazed at how quiet it was.
All of us were used to hearing the drone of the ancient on each time it kicked on plus now the two of us hear nothing. It is a unbelievable feature but occasionally I wonder if it is one or not. There is one funny indicator that I like telling people about. My Cat! Animals have a much more sensitive hearing ability plus he can still hear the gas furnace kick on. She instantly runs to the floor vent to wait for the rush of air to come out. She almost seems impatient as he waits. There is constantly a delay between when the gas furnace turns on plus when the air comes out. This is due to the high-limit switch. In simple terms this is section of the gas furnace plus makes sure the air is heated before sending it through the air duct. If your plan did not have this it would blow frigid air until it was able to heat it up each time. This would be like blasting the heat in the automobile while the engine is still cold. You would be miserable while I was in that time plus it would make you colder than you were plus it would take longer to heat the space or your car. If you ever notice that your gas furnace is blowing absolutely frigid air prior to moderate air you may want to have this section checked to make sure it is still working properly. Because this section gets a lot of use it can wear out over time plus should be section of your regular tune up routine too.
