Default Furnace cycle question

For those of you who have forced Air Gas furnace. Given that the outside temperature is around 20~25 degrees plus some cold wind. How often should your furance cycle if you keep indoor temperature themostat set at 70 degrees?

Yes, I know some of you will factor the size of the furnace vs sq.ft of your house. Or say depends on how much insulation you have in your house or how bad/good your windows are. But given when a house is properly insulated and windows have a bit of a draft (can't be perfect.) and located in NorthEast (New Jersey) having a typical 2 story colonial home.

I notice my furnace would kick in every 5 minutes and runs for 20 minutes, and off for 5 minutes and again for 20 minutes. So within the hour, the furnace would cycle 25 + 25 = 50, it runs 40 minutes out of the 50.

The other night, I kept it at 65, it would run for 10 minutes and be off for 10 and repeats this way. So at 65 degrees, it cycles 3 ~ 4 times an hour. And when set at 70, it comes on more often and runs longer. Is this normal?

Yes, I change the filter every 30 days. The ducts are clean and house is insulated fairly well, even the attic.

that seems very frequent but I keep mine at 64 degrees and id say ever 20 min it will kick in. I'm also losing A LOT of hot air through the 2 stairways that are stacked up to the 3rd floor.

I also happen to have the thermostat right by the first stairway as well, so it always reads colder than it is.

THis is the first force air system I've ever had and it just seems like its on an awful lot.

There is a setting that sets the cycle rate. It will allow a greater variation of temps. before the unit cycles. But more variation means less cycling/ more run time.

i think it sounds right. we set it low and it hardly ever goes on

it also assumes you have a single stage system (older systems, 80% furnaces)

new furnaces will go on more frequently with less heat to keep it a nice constant temp.
