Having a working furnace is critical during the winter. However, like any appliance, your furnace will sometimes need repair. One common sign that your furnace needs attention is short cycling.
What is Short Cycling?
Short cycling occurs when the furnace repeatedly turns on for a short time and then switches off. If your furnace is short cycling, call a repair technician as soon as you can. If it’s not addressed, short cycling creates a number of issues for your heating system, including:
- Skyrocketing energy bills. Your furnace draws more energy when it’s starting up. If it’s constantly starting and stopping, it will consume more power and drive up your energy costs.
- Frequent breakdowns. Short cycling puts additional strain on your furnace, causing it to wear out more quickly. This leads to more frequent repairs and can shorten the lifespan of your heating system.
- Home discomfort. Short cycling creates uneven temperatures throughout your home, making it difficult to stay comfortable.
Causes of Short Cycling
Here are some of the most common reasons for your furnace to short cycle.
Clogged Air Filters
Dirty air filters will become clogged and restrict airflow. The lack of airflow prevents air from reaching the furnace’s heat exchanger. This causes your furnace to overheat and shut down. Make sure to change your air filters regularly.
Like a clogged air filter, a blocked vent will restrict your furnace’s airflow. Restricted airflow causes your furnace to short cycle. Ensure that all of your vents are open and are not obstructed. For the best airflow, keep the vents open even in unused rooms.
Furnace is Too Big For Your Home
If your furnace is too big, it will heat your home quickly, then shut down. As your home starts to cool, the furnace will switch on again, then shut off. If your furnace isn’t sized correctly, the best solution is to replace it.
