There is much debate surrounding whether heat pumps and auxiliary heat should run simultaneously. Some believe that doing so is the most efficient way to heat a home, while others argue that it puts unnecessary strain on the system. Ultimately, the decision comes down to personal preference and the specific needs of the home.
If your heat pump is struggling to keep up with the demand for heat in your home, you may be wondering if it’s okay for both the heat pump and auxiliary heat to run simultaneously. The answer is yes – in fact, this is often the most efficient way to heat your home during extreme cold snaps. Here’s a closer look at how these two systems work together to keep you warm.
The Heat Pump A heat pump is responsible for extracting warmth from the air or ground outside and delivering it into your home. During milder weather, this system can usually handle all of the heating needs for your home on its own.
However, when temperatures dip below freezing, the heat pump struggles to extract enough warmth from the outside air to meet demand. That’s where auxiliary heat comes in The Auxiliary Heat System
Most homes with a heat pump also have an auxiliary or backup heating system – typically electric resistance coils or a gas furnace. This system kicks in when needed to supplement the output of the heat pump and help maintain a comfortable indoor temperature. So when temperatures drop and your heat pump can’t keep up, both systems will run together until things warm back up again.
While running both systems simultaneously does use more energy than running just the heat pump alone, it’s still more efficient than relying on your auxiliary system as your primary source of heat.
Should Heat Pump Run While on Auxiliary Heat?
If your heat pump is running while on auxiliary heat, it may be an indication that something is wrong with your system. First, check to see if the outdoor temperature is above the freezing point. If it is, then the problem may lie with your heat pump itself.
It could be low on refrigerant or there could be a problem with the compressor. If the outdoor temperature is below freezing, then the most likely culprit is a frozen evaporator coil. This can happen when there isn’t enough airflow over the coil or if the coil itself is dirty.
Either way, you’ll need to call a qualified technician to take a look at your system and make any necessary repairs.
Should the Heat Pump And Furnace Be Running at the Same Time?
If you have a heat pump, it should be running at the same time as your furnace. This is because the heat pump is responsible for moving heat from one place to another, and the furnace is responsible for generating heat. By running both at the same time, you can ensure that your home is being heated efficiently.
Does the Compressor Run When the Aux Heat is On?
The compressor is the heart of the air conditioner, and it doesn’t run when the Auxiliary heat is on. The auxiliary heat is used to supplement the heat provided by the compressor, and it usually comes on when the temperature outside is very cold. When the auxiliary heat is on, you’ll notice that your air conditioner’s fan will continue to run, but the compressor will be off.
What Temperature Should a Heat Pump Use Auxiliary Heat?
If your heat pump is using auxiliary heat, it means that the ambient temperature outside is too cold for the heat pump to work efficiently. The ideal temperature for a heat pump to operate is between 20 and 30 degrees Fahrenheit. When the temperature drops below 20 degrees, the heat pump will start to use auxiliary heat to maintain a comfortable indoor temperature.
The amount of auxiliary heat used will depend on how cold it is outside and how much heat is needed to maintain a comfortable indoor temperature.

How Long Should Aux Heat Run?
If your heat pump is running continuously in Auxiliary Heat mode, there may be a problem. Find out how long the Auxiliary Heat should run and what to do if it doesn’t shut off. auxiliary heat is designed to provide temporary heating when the outdoor temperature drops and the heat pump can no longer efficiently move heat into your home.
In general, you should only see Auxiliary Heat come on for brief periods of time – typically no more than 10-15 minutes at a time. If your system is running in Auxiliary Heat mode for extended periods of time, there may be an issue that needs to be addressed. There are several reasons why your system might stay in Auxiliary Heat mode for too long:
1. The most common reason is simply that the thermostat is set too high. Your system will continue to run in Auxiliary Heat mode until it reaches the temperature you’ve set on the thermostat, regardless of how long it takes. To avoid this, make sure you set your thermostat to a reasonable temperature – one that won’t cause your system to overwork itself trying to reach an unattainable goal.
2. Another possibility is that there’s something blocking the airflow through your system. This could be anything from dirt and dust build-up on the coils to a blockage in the ductwork itself. restricted airflow can cause all sorts of problems for your HVAC system, so it’s important to make sure everything is clear and unobstructed.
A professional HVAC technician can help you troubleshoot this issue and get things back up and running smoothly again.
Ecobee Allows Heat Pump And Aux Heat to Run Simultaneously
If you have an ecobee3 thermostat, you know that it can be tricky to keep your home comfortable while also being energy efficient. One of the features that can help with this is the ability to allow your heat pump and aux heat to run simultaneously. This can be a great way to make sure that your home is heated evenly and efficiently, without running the risk of overworking your system. Here’s how to do it:
1. Go into the Settings menu on your ecobee3.
2. Select Equipment Settings.
3. Find the option for Heat Pump Auxiliary Heat Enablement and set it to “On.”
4. Save your changes and exit the menu. Now, when your ecobee3 senses that both your heat pump and aux heat are needed, it will allow them to run at the same time.
This can help save energy and money while keeping your home nice and comfortable all winter long!
Heat Pump Auxiliary Heat Always on
If your heat pump is equipped with auxiliary, or backup, heat, you may notice that it seems to be running all the time. This is because Auxiliary Heat is designed to kick in when the outdoor temperature drops and the heat pump can no longer efficiently extract heat from the air. Auxiliary Heat is typically electric resistance heating coils or a gas furnace.
The coils work by converting electricity into heat, while a gas furnace uses burning fuel to create warmth. While these methods of creating heat are less efficient than a heat pump’s usual mode of operation, they’re still more efficient than an unassisted electric heater or baseboard heater. If you find that your Auxiliary Heat is coming on too often, there are a few things you can do to mitigate the issue.
First, make sure that your home is properly insulated and that there are no gaps or leaks where cold air can enter. You can also install weatherstripping around doors and windows to further seal in warmth. Additionally, consider using a programmable thermostat to better manage when Auxiliary Heat comes on and goes off.
By making small changes like these, you can help keep your home comfortable all winter long without breaking the bank!

How to Stop Auxiliary Heat from Coming On?
1. Understanding Auxiliary Heat: Auxiliary heat is a feature of HVAC systems that provides supplemental heating when the primary heating system is unable to maintain the desired temperature. While auxiliary heat is a useful feature in extreme weather conditions, it can also cause higher energy bills if not used efficiently.
2. Adjusting Thermostat Settings: One way to prevent auxiliary heat from coming on is to adjust the thermostat settings. The thermostat should be set to a temperature that is comfortable for you, but not too high. Setting the thermostat too high can cause the auxiliary heat to turn on, which can increase energy bills. Additionally, it is important to avoid sudden changes in temperature, as this can also trigger the auxiliary heat.
3. Improving Insulation: Insulation is essential to maintaining the desired temperature in your home. Poor insulation can cause the heat to escape and trigger the auxiliary heat. To prevent this, homeowners should ensure that their homes are properly insulated. Adding insulation to the walls, ceiling, and floors can reduce heat loss and improve the efficiency of the HVAC system.
4. Identifying and Sealing Air Leaks: Air leaks can also cause the heat to escape and trigger the auxiliary heat. Homeowners should identify and seal air leaks to prevent this from happening. Common sources of air leaks include windows, doors, and ductwork. Sealing air leaks with weather stripping and caulk can improve the efficiency of the HVAC system and reduce the need for auxiliary heat.
5. Ventilation and Airflow: Proper ventilation and airflow are essential for maintaining the desired temperature in your home. Homeowners should ensure that their HVAC system is properly ventilated and that air is flowing freely throughout the home. Blocked or closed vents can cause the heat to become trapped and trigger the auxiliary heat.
6. Optimizing HVAC System Performance: Regular maintenance and optimization of the HVAC system can reduce the need for auxiliary heat. Homeowners should schedule regular maintenance checks with a professional HVAC technician to ensure that the system is running efficiently. Additionally, upgrading to a more efficient HVAC system can also reduce energy bills and the need for auxiliary heat.
