A new heat pump running constantly can signal underlying performance issues, potentially indicating incorrect installation, thermostat misconfiguration, or system design problems. Continuous operation not only increases energy consumption but may also suggest inefficiencies that require immediate professional assessment. Understanding the root causes and implementing strategic diagnostics can help restore your heat pump’s optimal functionality and prevent long-term system damage.
Why Does a New Heat Pump Run Non-Stop?
Potential Causes of Continuous Operation
Heat pumps are designed to cycle on and off to maintain consistent temperatures. When a new heat pump runs constantly, several critical factors might be responsible:
Thermostat Configuration Problems
- Incorrect temperature settings
- Miscalibrated sensor readings
- Incompatible system programming
System Sizing Challenges
| Sizing Factor | Impact on Performance |
|---|---|
| Undersized Unit | Constant Running |
| Oversized Unit | Frequent Short Cycling |
| Perfectly Sized | Optimal Performance |
Diagnostic Approach for Continuous Operation
Initial Troubleshooting Steps
- Verify thermostat settings
- Check temperature differential
- Inspect outdoor unit functionality
- Assess airflow restrictions
