What is considered short cycling for a furnace?
A furnace “short cycles” when it turns off before reaching the desired temperature. This means that if your thermostat is set to 72 degrees, the furnace may shut down at 65 or 68 degrees, but will never reach 72 degrees. Short cycling can also be used to describe a furnace that turns on and off too often.
Why does my furnace run every 15 minutes?

If it’s 5 to 10 degrees outside, a two-stage furnace will run in the partially-open position and only use 70% of the energy it normally would.
How long is too long for a furnace to run?
Industry research shows some expected time frames for how long a furnace runs during a particular cycle. Running 10 to 15 minutes per cycle seems acceptable. So is running as long as 20 minutes. Even running every seven or eight minutes may not be a problem, as other factors could lead to more frequent cycling.
