What Does Auxiliary Heat Mean on My Thermostat?

Like most people, you don't think about your thermostat often. But did you know that it can do more than regulate the temperature in your home?

An energy-efficient home heating system may require auxiliary heat, an additional source of heat that kicks in during high-demand periods.

When temperatures outside are freezing, your home heating system may be unable to keep up with demand. Many thermostats have auxiliary heat settings that allow you to use another form of heating to supplement your regular heating system. So what does auxiliary heat mean on my thermostat? And how can I use it to save money on my energy bills? We will explain.

What Is Auxiliary Heat?

Auxiliary heat is an additional heating source used by some modern HVAC systems. It is designed to supplement the regular heating system when outdoor temperatures become too cold to work efficiently. The auxiliary heat works with the central system, usually a furnace or boiler, to ensure that your home remains comfortable no matter how cold it gets outside.

Auxiliary heat kicks in when the temperature drops below a certain point and remains on until the thermostat detects your desired level of warmth. The auxiliary heating system may be powered by electricity, gas, or oil, depending on the HVAC system you have installed in your home.

How To Prevent Auxiliary Heat?

If you wish to save money on your energy bills and avoid using the auxiliary heat feature, there are several things that you can do:

1. Ensure Your HVAC System Is Maintained Correctly

The HVAC system should be cleaned and serviced regularly to ensure it runs efficiently. This will help reduce the need for auxiliary heat and keep energy costs low.

2. Change Air Filters Frequently

Air filters trap dust, debris, and other irritants from circulating through your home. If these filters become clogged up, they can reduce the airflow to the HVAC system. This means that the auxiliary heat will kick on more frequently as it has to compensate for this reduced airflow. To ensure that your auxiliary heat is running efficiently, change out the air filters at least once every three months.

3. Insulate Your Home

Insulation helps to keep the temperatures in your home consistent by providing a barrier between the inside and outside of your house. Proper insulation can also reduce the need for auxiliary heat as it keeps warm air from escaping and cool air from entering, meaning less work for your HVAC system.

4. Get an Energy Audit

An energy audit will tell you what areas of your home need the most insulation. It is also a great way to identify and address potential air leaks or other problems with your HVAC system. Once these issues are fixed, it may reduce the need for auxiliary heat in colder months. For example, if your home loses heat through your windows or doors, you can efficiently insulate these areas and reduce the need for auxiliary heat.
