If your furnace is running longer than expected, it could drive up your energy bills and signal the need for repairs. While there isn’t a one-size-fits-all answer to how many hours your furnace should run in a day, it depends on factors like Central KY’s fluctuating winter temperatures, your home’s insulation, and how cold it gets on any given day. However, you can often detect issues with your furnace by simply observing any significant changes in its run times.
Typical Furnace Heating Cycles
Most thermostats trigger the furnace to start when the temperature drops around 1.5 degrees below the set point and stop when it rises about half a degree above it. During Central KY’s colder months, when your furnace is working harder to keep your home warm, it may run more frequently, but under normal conditions, each cycle should last about 15 to 20 minutes. During particularly cold spells, like those experienced in December and January, your furnace may need to run longer to maintain a comfortable temperature.
Common Causes of Extended Furnace Run Times
If you notice your furnace running longer than usual, the first step is to check the air filter. In Central KY, homes can experience higher levels of dust and allergens, especially in the fall, leading to clogged filters. A dirty filter can restrict airflow, reducing the system’s efficiency and causing it to run longer. If replacing the filter doesn’t resolve the issue, it’s time to call in a professional technician.
Several problems can cause a furnace to run inefficiently, including a malfunctioning blower, leaky ductwork, or dirty burners. Only a professional assessment can identify the specific cause and ensure your furnace operates at peak efficiency.
