Heat pumps are popular in Fort Worth. They use electricity to move heat from one place to another. This makes them energy-efficient heating solutions, especially during mild temperatures. But when it gets colder, you may notice your AUX heat coming on. Let’s dig deeper into what this means for you.
Understanding Your Heat Pump
How Heat Pumps Work
We spoke in detail about how your heat pump works on an earlier blog, which you can read here. But I will go ahead and give you a quick summary.
Heat pumps operate by taking heat from the air or ground outside and moving it indoors. Even when it’s cold outside, there is still heat available in the air. The heat pump extracts this warmth and sends it into your home through the indoor unit.
When the outdoor temperature drops significantly, your heat pump might struggle to keep up. That’s where AUX heat comes in. It acts as a backup to ensure your home stays warm and cozy.
The Role of AUX Heat
AUX heat is important for several reasons. It helps:
- Maintain warmth during very cold days.
- Prevent your home from getting too cold.
- Support your main heat pump system.
When the heat pump can no longer keep up with the demand for heat, AUX heat steps in. This is especially true during extreme weather when you might need emergency heat to stay comfortable.
When Does AUX Heat Activate?
Temperature Triggers
AUX heat kicks in when:
- The outside temperature is below freezing: Heat pumps lose efficiency in extreme cold.
- You need a quick boost in temperature: If your home is too cold, AUX heat can raise the temperature quickly.
- Your heat pump is in defrost mode: Sometimes, heat pumps need to melt frost off their coils. During this defrost cycle, AUX heat helps keep your home warm.
Signs AUX Heat is On
You may notice a few signs that AUX heat is running:
- Your thermostat shows AUX heat or emergency heat.
- Your energy bills are higher than usual.
- You feel a sudden increase in warmth.
If these signs appear, understand that your heat pump is trying to keep you comfortable. The heating cycle may change, and you might rely more on heat strips during colder days.
Efficiency of Heat Pumps vs. AUX Heat
