"Short Cycling" is when a furnace turns on and off too quickly before it has heated your home to the thermostat set point. Sometimes, no heat is made at all before shutting down.
Here are the top reasons why your furnace may be short cycling:
Too Big
Bigger is not better and it will not heat up your home any faster. A furnace that is too powerful for your space will consume too much energy, short cycle, and will cost you big in the long run.
Overheating
Your furnace may shut itself down to protect itself from over heating. If it overheats, it may crack the heat exchanger, leaking carbon monoxide into your home.
Dirty Air Filter
The main cause for overheating is from restricted airflow from a dirty air filter, which can block interior vents and exhaust vents to the roof.
Malfunctioning Thermostat
If your thermostat is malfunctioning, anything can happen from short cycling to a complete shut down.
If your thermostat is improperly installed too close to a heat source, the thermostat will get hotter faster than the rest of the home, causing short cycling.
