When your heat pump won’t shut off in Palatine, IL, it can leave you wondering if something is seriously wrong. While these systems are built to run longer than traditional HVAC equipment, especially during extreme temperatures, nonstop operation often indicates a deeper issue. Knowing what to look for can help you decide whether it’s time to call in a professional. Here’s what it could mean when your heat pump just keeps running.
Thermostat or Sensor Issues
Sometimes the issue lies with the thermostat, not the heat pump itself. If it’s miscalibrated or malfunctioning, it might keep signaling the system to run even after your home is comfortable. A stuck relay or a faulty sensor could also be the cause. If you’re seeing temperature swings or the thermostat isn’t responding properly, this might be the issue.
Dirty Coils or Clogged Filters
When airflow is restricted, your system has to work overtime. Clogged air filters or dirty coils can keep your heat pump from moving heat efficiently, which can cause it to run constantly in an effort to catch up. Simple maintenance like replacing the air filter or having the coils cleaned can help your system run more efficiently and cycle properly.
Refrigerant Issues
Low or leaking refrigerant prevents your heat pump from heating or cooling effectively. If the system can’t meet the temperature you’ve set, it will just keep running.
Because refrigerant handling requires EPA certification, this is an issue that should only be diagnosed and repaired by a licensed HVAC technician.
When It’s Time to Call a Pro
If you’ve tried the basics and your system still won’t shut off, it’s time to call in a professional. Warning signs such as ice on the unit, lukewarm air, loud noises, or frequent cycling can all point to something more serious. Leaving the problem unchecked can lead to higher energy bills, more wear and tear, and less comfort.
