When the temperatures dip and the winter winds blow, you want to ensure your home is warm and comfortable. In that regard, having a reliable heat pump is essential.

Understanding What Emergency Heat Is

The first step in understanding when a heat pump will switch to emergency heat is learning what it is. In short, EM heat is an auxiliary system designed to kick in when the temperature outside drops below freezing and the standard operating mode of the heat pump becomes inefficient or unable to keep up with demand. The system consists of electric resistance strips or a gas furnace providing additional heat to keep your home warm.

Identifying the Symptoms of Emergency Heat

The next step is identifying when a heat pump may switch to emergency heat. The most common symptom is an increase in energy bills due to the extra wattage used by the system.

However, depending on the unit type, you might also experience a slightly louder sound when it kicks in or see condensation forming near your unit’s vents. Additionally, if you feel cold air coming from your registers instead of warm air, this could be a sign that your heat pump has switched to emergency mode.

Knowing When to Use Emergency Heat

When should you use emergency heat? Generally speaking, you should only activate the system if the outside temperature drops below 32 degrees Fahrenheit.

However, if you live in an area that experiences extreme temperatures, consider starting EM heat at lower temperatures. Additionally, if your heat pump is over ten years old or has had multiple repairs in a short period, switching to emergency heat may be a good idea and can help prevent further breakdowns.

If you notice that your heat pump is broken and unable to keep up with demand, activating your emergency heat system can be a good option. It would help if you used it in short bursts rather than as a primary or full-time solution for your home’s heating needs. Since it consumes a ton of energy, using it too often can lead to skyrocketing electricity bills.

The Benefits of Knowing When to Switch to Emergency Heat

Finally, it’s important to emphasize the benefits of knowing when a heat pump will switch over to emergency mode. By understanding how your system works and when it’s appropriate to use emergency heat, you can avoid costly energy bills and prolong the life of your unit.

With that said, if you need help with when to activate emergency heat or have any other questions about your system, contact an experienced heating and cooling technician for help.
