Your furnace is one of the essential pieces of equipment in your home. It keeps you warm and comfortable all winter long!
When you are choosing a new furnace , size plays a vital role. Furnaces that are too small will not keep up with the demand of your home, leading to short cycling. Short Cycling occurs when a furnace turns on and off multiple times before reaching its desired temperature.

So, when it starts cycling on and off, it can be frustrating. We will discuss the reasons why your furnace might be turning on and off and what you can do about it.
1. There Is a Problem With the Thermostat
The thermostat is crucial for regulating the temperature in your home. If it is not set correctly, or if it is malfunctioning, this can cause your furnace to cycle on and off repeatedly. Ensure the thermostat is set correctly and its batteries are working properly. If this does not solve the problem, you should call a professional for help.
An expert will check the thermostat’s wiring, the sensitivity of its internal components, and the temperature readings to ensure that it is working correctly.
2. The Air Filter Is Clogged Or Dirty
The air filter helps remove airborne particles like dust, pollen, and pet dander from the air circulating through your home. Over time, this filter gets clogged with dirt and debris, limiting the airflow that can pass through. When this happens, it causes the furnace to work harder than necessary, cycling on and off. If the air filter isn’t changed regularly, it can cause your furnace to overheat, leading to further issues and costly repairs.
3. The Furnace Ventilation System Is Blocked
Ventilation is a crucial component of the HVAC system, and if it is blocked or not working correctly, your furnace will not cycle usually. If your ventilation system is blocked, it can cause the pressure in the furnace to build up too quickly, causing the furnace to shut off before it has completed its normal heating cycle. To determine if your ventilation system is blocked, check your ducts for visible blockages, such as dirt and debris. You should also inspect the outside of your furnace to ensure there are no obstructions near the unit that could be causing an issue with airflow. If you still can’t identify the reason of the problem, it may be worth calling a professional HVAC technician to inspect your system.
4. The Blower Motor is Malfunctioning
The blower motor is responsible for circulating air throughout your home and is an essential HVAC system component. If the blower motor is malfunctioning, it won’t be able to properly circulate air through the furnace, causing it to keep cycling on and off. To determine if the blower motor is malfunctioning, experts use techniques like voltage testing and amp draws testing to diagnose the issue. When repairing a faulty blower motor, it is best to always call a professional HVAC technician for assistance.
