An optimally functioning heat pump should run in cycles. Short-cycling occurs when a heat pump turns on and off frequently without completing a heating or cooling cycle.
What causes a heat pump to short‑cycle (turn on and off too often)?
- The system is oversized — it heats/cools your home too fast and shuts off prematurely
- A faulty or poorly placed thermostat sends erratic signals to the pump
- Clogged air filters restrict airflow and force the system to cycle before completing a full run
Here’s why heat pumps short cycle in Norco, CA:
Oversized Heat Pump Causing Short Cycling?
HVAC professionals refer to a heat pump as oversized if its temperature regulation capabilities exceed your home’s heating or cooling load. An oversized system warms your home too fast and shuts down before a cycle is complete. This can also make the system run louder than normal.
Always use a professional service technician to calculate your home’s heating and cooling load before installing a new heat pump. This will help you to choose a heat pump that matches your home’s temperature needs.
Faulty Thermostat Triggering Frequent Heat Pump Cycling
Usually, a thermostat communicates the temperatures you want to the heat pump. The device relays this information through wires that connect it to the heat pump. Any damage to these wires may interrupt smooth communication between your heat pump and thermostat, resulting in short cycling.
Also, if you place your thermostat in an area that does not accurately represent your home’s temperature, the device may send conflicting signals to the heat pump. Avoid locating the thermostat near the kitchen or windows and doors.
Consider placing the thermostat in a centrally located room in your home where it reads the temperatures accurately. Also, you can contact one of our service technicians to inspect the thermostat and ensure proper system communication.
Clogged Filters Leading to Short Cycling Issues
An air filter protects you and your family from pollutants that lower indoor air quality by trapping them in the mesh. These contaminants include pet dander, pollen, dust and debris.
Over time, these contaminants accumulate on the filter and interfere with the proper flow of air into the heat pump. As a result, short cycling occurs. Consider checking the air filter and changing it often to promote uninterrupted airflow.
