Homeowners in Shenandoah may notice that their furnace turns on and off more frequently during the cold December months—a phenomenon known as short cycling. While it may seem harmless, short cycling can reduce comfort, increase energy bills, and put extra wear on your HVAC system.
Understanding the causes and solutions can keep your home warm, efficient, and stress-free this winter.
Common Causes of Short Cycling in Winter
- Oversized HVAC System – A furnace that’s too large for your home heats quickly and shuts off before completing a full cycle.
- Thermostat Issues – Poorly placed or miscalibrated thermostats can trigger frequent on/off cycles.
- Dirty Air Filters or Blocked Vents – Restricted airflow causes the system to overheat and shut off prematurely.
- Refrigerant or Component Problems – Low refrigerant (for heat pumps) or worn components can make the system cycle improperly.
- Cold Outdoor Temperatures – Rapid temperature swings in December make heating demands inconsistent, triggering short cycles.
How to Fix or Prevent Short Cycling
- Check and Replace Air Filters – Clean airflow improves efficiency and prevents overheating.
- Ensure Proper Thermostat Placement – Avoid drafts, heat sources, or blocked areas.
- Schedule Professional HVAC Maintenance – Technicians can adjust the system, inspect components, and optimize performance.
- Consider System Sizing Review – If your furnace is oversized, a professional may recommend solutions for better efficiency.
