7 Causes and Solutions to a Furnace Short Cycling
As the colder months set in, one of the most frustrating issues homeowners may experience is a furnace that keeps turning off and on—also known as short cycling. If you’ve noticed your furnace isn’t running properly or is constantly shutting off before reaching your desired temperature, it could be an indication of underlying issues. Why is my furnace short cycling and what can be done to fix it? Here, we’ll explore the most common causes of furnace short cycling and how to resolve them.
1. Dirty Air Filters
One of the most common reasons for short cycling is a dirty or clogged air filter. When your air filter is blocked with dust, dirt, and debris, it restricts airflow, causing the furnace to overheat. As a safety measure, the furnace will shut off to prevent damage. Replacing the air filter regularly is essential for maintaining good airflow and furnace efficiency. If you’re unsure of how to do this, or need help choosing the right filter for your system, feel free to contact Lochard HVAC, Plumbing, and Service for expert guidance. If you’re facing other HVAC issues, our team also provides heating services in Piqua, Troy, and surrounding areas.
2. Faulty Thermostat
A malfunctioning thermostat can also cause your furnace to short cycle. If the thermostat is inaccurately sensing the room temperature, it may trigger the furnace to start and stop repeatedly. A faulty thermostat can be repaired or replaced, but it’s important to have an experienced technician perform the diagnosis. If you suspect your thermostat is the issue, call us today.
3. Dirty or Blocked Flame Sensor
The flame sensor in your furnace ensures the burner is operating correctly and safely. If this sensor becomes dirty or faulty, it may cause the furnace to shut off prematurely as a safety feature. Cleaning or replacing the flame sensor is a simple task for an experienced technician. If you’re experiencing this issue, Lochard HVAC, Plumbing, and Service can help with furnace repairs and more. We specialize in providing reliable heating service and repair in Sidney and Bellefontaine.
4. Overheating Furnace
If your furnace is overheating, it may short cycle as a protective measure. Overheating can be caused by a variety of issues, such as poor airflow, a malfunctioning blower motor, or problems with the furnace’s internal components. This issue should be addressed immediately to prevent further damage. To ensure your furnace operates safely, routine maintenance and inspections are key. Lochard HVAC, Plumbing, and Service offers heating system tune-ups and furnace repair services to help prevent overheating and keep your system running efficiently.
5. Undersized Furnace
An undersized furnace may struggle to heat your home efficiently, causing it to run for a shorter time before shutting off. If your furnace is too small for your home, it will likely turn on and off frequently in an attempt to keep up with the demand for heat. If you suspect your furnace is undersized, it’s essential to consult with an HVAC professional to discuss your options. Our team at Lochard HVAC, Plumbing, and Service offers HVAC system design and installation services in Wapakoneta and Troy to help you choose the right system for your home.
6. Blocked Vents or Ductwork Issues
Blocked vents or issues with the ductwork can cause air to be restricted, which can result in your furnace overheating and short cycling. It’s essential to ensure that your vents are clear of any obstructions, and if the ducts are damaged or leaking, they should be repaired promptly. Lochard HVAC, Plumbing, and Service can perform a thorough inspection of your home’s HVAC system, offering solutions to any ductwork issues and helping to ensure your furnace operates properly.

Is short cycling bad for a furnace?
Yes, short cycling can be very harmful to your furnace. When a furnace repeatedly starts and stops, it causes unnecessary strain on the system, leading to increased wear and tear on components like the blower motor, flame sensor, and heat exchanger.
