If your heat pump is running non-stop but your home still feels cold, you’re not alone. Many homeowners in Mountain Brook, AL, experience this issue in winter. Since heat pumps transfer heat rather than generate it, certain factors can make them work overtime without warming your space effectively. Let’s explore why this happens and what you can do to fix it.
1. Extremely Cold Weather
Heat pumps work best in moderate climates but lose efficiency when temperatures drop below 30°F. In these cases, your system may run constantly to compensate. If your heat pump struggles during cold spells, consider using supplemental heating or upgrading to a model with better cold-weather performance. Call a professional if your auxiliary heat isn’t turning on when needed.
2. Dirty Air Filters or Blocked Airflow
A clogged air filter or obstructed vents restrict airflow, making it harder for your heat pump to distribute warm air. Check and replace filters every 1-3 months, and ensure vents aren’t blocked by furniture. If airflow still feels weak after cleaning, schedule a service call to inspect for deeper airflow issues.
3. Low Refrigerant Levels
Low refrigerant prevents your heat pump from extracting and transferring heat effectively, leaving your home feeling chilly. If you hear hissing noises or notice ice buildup on your outdoor unit, contact a professional immediately—low refrigerant often indicates a leak that requires expert repair.
4. Thermostat Issues
Incorrect settings or a faulty thermostat can cause your system to run constantly without properly heating your home. Ensure your thermostat is set to “heat” mode, not “emergency heat,” and verify the temperature settings. If your home still feels cold despite adjustments, a technician can recalibrate or replace your thermostat.
5. Aging or Inefficient Heat Pump
If your heat pump is over 10 years old, it may no longer heat efficiently, causing it to run longer with poor results. Routine maintenance can help improve performance, but if your system frequently struggles, it may be time for a replacement. Contact a professional to discuss upgrading to a high-efficiency heat pump that better suits your home.
6. Improper System Size
A heat pump that’s too small for your home will constantly run without adequately heating the space. If your system has always struggled to keep up with demand, an HVAC expert can perform a load calculation and recommend the right-sized system for optimal efficiency.
