When should I use my auxillary heat

When Should I Use My Auxiliary Heat? Expert Advice from California’s Leading HVAC Company – HVAC Beverly Hills As the most trusted name in home comfort across California, HVAC Beverly Hills often gets asked, “When should I use my auxiliary heat?” The term can be confusing for many homeowners, especially those using heat pumps in mild climates like Southern California.
Whether you're new to owning a heat pump or noticing your thermostat switching to “AUX” mode more often, this article explains everything you need to know about auxiliary heat, when it should be used, and how to optimize its performance for energy savings.

🔥 What Is Auxiliary Heat? Auxiliary heat (often displayed as "AUX HEAT" on your thermostat) is a secondary heating system that kicks in when your primary heat pump can’t keep up with the demand. It’s commonly used in heat pump systems, which work by transferring heat from the outside air into your home.
During very cold weather or when the heat pump goes into defrost mode, auxiliary heat turns on to help maintain your set temperature. In most cases, auxiliary heat is powered by electric resistance heating elements or a gas furnace backup.

🧠 How Auxiliary Heat Works  A heat pump is very efficient—until the temperature outside drops below 35°F to 40°F. At this point, the system can struggle to extract enough heat from the outside air. That’s when your auxiliary heat takes over to maintain indoor comfort.
It activates in two scenarios:

1. When outdoor temperatures are too low for the heat pump to work efficiently.
2. When you drastically raise your thermostat setting (more than 2–3 degrees).

Your thermostat is programmed to detect when it needs the extra help, switching to auxiliary heat automatically.

📍 When Should I Use My Auxiliary Heat in California? In Beverly Hills and other parts of Southern California, the climate is typically mild. That means auxiliary heat should only turn on occasionally, typically during:

• Cold winter nights or early mornings
• Rainy, windy, or stormy conditions
• Defrost cycles (when the outdoor unit temporarily pauses to clear frost)

If you notice auxiliary heat turning on too frequently, it might be a sign of a malfunction or an inefficient system—something that the experts at HVAC Beverly Hills can quickly diagnose and fix.

🚨 When Auxiliary Heat Becomes a Problem  While it’s great to have auxiliary heat as a backup, it’s not meant for regular use. That’s because it typically relies on electric resistance coils, which consume significantly more energy than your heat pump.
Here’s when you should be concerned:

• AUX heat stays on for hours at a time
• You see a sharp increase in your energy bill
• Your home still feels cold, even with the system running
• The heat pump is frozen or not working efficiently

In these cases, it’s time to call HVAC Beverly Hills—your local heating experts in California—for a system inspection.

✅ How to Minimize Auxiliary Heat Usage  Auxiliary heat is helpful, but since it’s costly, it’s best to limit how often it runs. Here are some tips to avoid overusing AUX heat and still stay warm:
1. Avoid Large Temperature JumpsRaise the thermostat gradually—no more than 2–3 degrees at a time. Sudden jumps trigger auxiliary heat unnecessarily.
2. Use a Programmable ThermostatSmart thermostats can optimize your heat pump and reduce reliance on auxiliary heating by adjusting settings based on usage patterns.
3. Schedule Preventative MaintenanceA dirty or failing heat pump will rely more on auxiliary heat. Let HVAC Beverly Hills perform seasonal maintenance to keep everything running efficiently.
4. Check Insulation and DuctsPoor insulation or leaky ductwork forces your system to work harder, which can lead to frequent AUX heat activation.
5. Monitor the Outdoor UnitIf your outdoor heat pump coil is iced over, it may rely on auxiliary heat until the system defrosts or is repaired.

🧊 Auxiliary Heat vs. Emergency Heat: What’s the Difference?  Homeowners sometimes confuse auxiliary heat with emergency heat—but they are not the same.

• Auxiliary Heat: Turns on automatically when the heat pump can’t keep up.
• Emergency Heat: Must be turned on manually by the user when the heat pump fails completely.

You should only switch to emergency heat if your heat pump is broken, and you’ve called HVAC Beverly Hills for repair. Emergency heat uses the same resistance heating elements, but it bypasses the heat pump altogether, making it very expensive to operate.

🌿 Is Auxiliary Heat Energy Efficient?  In short: no, not compared to a heat pump operating on its own.
While auxiliary heat provides essential backup in extreme conditions, it uses 3 to 5 times more electricity. This is why minimizing its use is crucial in energy-conscious households—especially in California, where utility rates are among the highest in the nation.
With smart operation and expert maintenance from HVAC Beverly Hills, you can ensure that auxiliary heat is only used when truly necessary—saving energy and money.
