What Does Aux Heat Mean on My Thermostat?

Have you noticed that your thermostat says it’s using auxiliary heat, but aren’t sure what that means or whether it matters? At Rooter Hero Plumbing & Air, we help our clients find solutions to their air conditioning and heating issues. Many property owners are confused by the term auxiliary heat and have questions about whether this is okay, or if it indicates there’s a problem with their system. If you have similar concerns, keep reading for some information that can help provide clarity on this important topic.

Auxiliary Heat - What Does it Mean?

Auxiliary heat is a backup system that kicks in when your primary heating system fails or shuts off. That means it's not actually the primary source of heat in your home, but rather something that kicks in when needed. Auxiliary heat is useful because it allows you to keep your home warm during times when your main heating system can’t perform well enough on its own. This normally occurs when outdoor temperatures drop below freezing.

How to Avoid Using Auxiliary Heat

While auxiliary heat is a great way to keep your home warm and cozy during the cold winter months, it also has a cost. The energy used by auxiliary heat will increase your monthly utility bill, so it's important to avoid using this type of heating unless absolutely necessary. If you’re concerned about rising utility bills, you can avoid the use of auxiliary heat with these tips:

  • Change filters regularly
  • Ensure proper insulation throughout your home
  • Make sure your thermostat isn’t set too high or low
  • Keep your HVAC system well-maintained
  • Invest in an energy audit to determine why your heating costs have risen

By following the examples listed above, you should be able to get your energy bills lowered by making it easier for your regular heating system to maintain indoor temperatures.

When to Get Help from a Professional HVAC Company

The use of auxiliary heat is normal from time to time, especially during the colder months of the year. However, if you have noticed that your heating system is switching to auxiliary more often than it should, this could indicate a malfunction. Troubleshooting this issue can be complicated, as it could be a symptom of a variety of causes. A professional HVAC technician can inspect your heating system for signs of trouble and will be able to provide a customized solution that will get your system back under control quickly.
