Short cycling occurs when your HVAC unit turns on and off more frequently than usual within a short period. HVAC short cycling can lead to higher energy bills and, possibly, complete system failure. Fortunately, there are certain steps you can take to avoid HVAC short cycling in the winter.
Change Your Air Filter Frequently
Your HVAC system relies on adequate airflow to work properly. A clogged air filter restricts airflow, which could make your HVAC system work harder and possibly overheat. The HVAC unit will shut itself down as a safety precaution to prevent the overheating from getting worse. Check your air filter regularly and change it if it’s dirty to allow for sufficient airflow.
Ensure Correct Thermostat Placement
Your thermostat should be centrally located on an interior wall. A thermostat that’s poorly placed, such as near your registers or your furnace or in direct sunlight, will heat up more quickly than the rest of the house and trigger your HVAC unit to turn off more frequently.
Proper Sizing
When purchasing an HVAC unit, it’s crucial to select the right size unit for your home with the help of HVAC professionals. An oversized system will heat your home too quickly and turn off after a short period.
Seal Air Leaks
Poor insulation and inadequately sealed ductwork and windows will allow heated indoor air to escape. Consequently, your HVAC unit will work harder to regulate your indoor temperature, which could result in short cycling. Make sure your home has adequate insulation and that your ducts and window frames are properly sealed to avoid HVAC short cycling.
Schedule Regular Maintenance
Having an HVAC professional perform seasonal preventive maintenance will help prevent short cycling and other problems and ensure your system is ready for the heating season.
HVAC short cycling is a potentially harmful problem. Take the necessary steps to prevent it to avoid expensive repairs. If you need HVAC maintenance, repair, or replacement services in the Dayton area, contact the heating and cooling professionals at Detmer and Sons.
