When your furnace short cycles, it turns on and off frequently without reaching the desired temperature. This issue can often leave your home cold while raising your energy bills. Here are five of the most common reasons your furnace may short cycle in Newburgh, IN.

1. Clogged Air Filter

Dirty air filters impede airflow into your furnace. This stops the warm air from circulating through your home, allowing it to overheat your furnace’s internal components. Your system will then shut down to prevent any damage, which causes short cycling.

2. Air Leaks

Short cycling can also occur when you have a home with multiple air leaks. These leaks can be due to your ductwork, windows or poor insulation. The harder your furnace has to work to heat the home, the more likely it can overheat and suddenly shut down.

3. Outdated Thermostat

Short-cycling furnace issues are actually often caused by the thermostat. It may no longer be able to accurately read the temperature in the home or follow your settings. Upgrading to a programmable thermostat can lower your energy bills and boost your comfort.

4. Wrong Furnace Size

A furnace that’s too big for your home will quickly distribute heat before turning off. This can lead to uneven heating. An incorrectly sized furnace will also need more repairs over time.

5. Deteriorated Flame Sensors

Your furnace’s flame sensor ensures that the system is safely burning fuel. During the burning process, small amounts of moisture can settle on this sensor, causing rust and corrosion. Deteriorated flame sensors impact your furnace’s efficiency as well as your safety.
