What Are the Signs Your Heat Pump Needs to Be Replaced?
Heat pumps are durable, but as components wear down, performance and efficiency decline. You should consider scheduling a heat pump replacement if:
- Your system is over 15 years old: Older units lose efficiency and require increasingly frequent repairs.
- Energy bills are spiking: Failing compressors or motor components force the unit to consume significantly more electricity.
- Frequent short cycling: The heat pump constantly cycles on and off without reaching your thermostat setpoint.
- Unusual metallic noises: Loud grinding, squealing, or rattling indicates major mechanical failure.

Installation Considerations & Solutions
Challenge: Uneven heating or cooling between floors after converting to a heat pump.
Solution: Incorrect system sizing or inadequate ductwork design causes hot/cold spots. Our technicians perform precise Load Calculations (Manual J) prior to installation to ensure your new heat pump matches your exact home square footage and air volume requirements.
Challenge: Concerns about cold winter performance during Midwest freezing snaps.
Solution: We install cold-climate heat pumps engineered with variable-speed technology that deliver continuous heat even in sub-freezing weather. For added peace of mind, we can configure auxiliary electric heat strips or a dual-fuel hybrid system paired with your gas furnace.
Challenge: Older home electrical panels incapable of handling modern heat pump power demands.
Solution: Because A+ Derr is a licensed multi-trade electrical contractor, our team evaluates and upgrades your electrical sub-panel and outdoor disconnect box during the HVAC installation process—no need to hire a separate electrician.
How Do You Get the Best Results From Your New Heat Pump Installation?
A new heat pump is a smart upgrade that provides both heating and cooling from a single unit while keeping utility bills manageable. In the Evansville and Louisville regions—where weather ranges from humid summer heat to freezing winter temperatures—proper sizing and expert placement make all the difference in long-term performance.
Professional installation guarantees that your heat pump is matched to your home’s layout, airflow needs, and duct design. A properly calibrated system operates quietly, maintains consistent indoor humidity, and reduces wear on internal components, extending the overall life of the equipment.
