We've have a lot of people ask "does putting my heat pump on auto mode save energy?" In this article Oxy Air will talk through the different options for "how to save energy with your heat pump".

Your Guide to Auto Mode & Why It Isn’t the Energy Saver You Think It Is. 

The tempting ‘Auto’ mode on our air conditioning units promises to create the perfect indoor climate without any manual adjustments. It sounds convenient, right? But here’s the cold, hard truth: the ‘Auto’ mode might not be the energy-efficient saviour you think it is. In this blog post, we’re going to dive into why you should steer clear of the ‘Auto’ mode and opt for the ‘Heating or cooling’ mode instead to save energy with your heat pump. 

Understanding ‘Auto’ Mode

Does putting my heat pump on auto mode save energy? Before we get into the reasons why ‘Auto’ mode can be problematic, let’s break down how it works. In ‘Auto’ mode, your air conditioning unit employs a heat pump to maintain the temperature you’ve set. It does this by constantly toggling between heating and cooling functions as the room temperature fluctuates. On the surface, this seems like a smart way to keep your space comfortable without you lifting a finger. However, there’s a hidden cost to this convenience.

The Energy-Wasting Cycle

Each time your unit switches from heating to cooling (or vice versa), it consumes a significant amount of energy. The process of transitioning between heating and cooling modes requires the system to work overtime, and that means more electricity usage. This constant cycling not only drives up your energy bill but also places unnecessary strain on your HVAC system.

Imagine this scenario: It’s a chilly evening, and you set your thermostat to 72°F in ‘Auto’ mode. Your heat pump starts warming the room until it reaches 72°F, then promptly switches to cooling mode as the temperature inches a fraction above your desired setting. Moments later, it flips back to heating mode as the room cools down again. This back-and-forth dance continues, consuming more energy than necessary and causing wear and tear on your HVAC system.

Energy Efficiency 101

Does putting my heat pump on auto mode save energy? If you’re looking into how to save energy with your heat pump, here’s what you should do: ditch the ‘Auto’ mode and choose ‘Heating or cooling’ instead. In ‘Heating’ or ‘Cooling’ mode, your air conditioning unit operates with a single goal in mind: to either warm or cool your space until it reaches the desired temperature. Once it achieves that, it maintains the setting without unnecessary switches.

By manually selecting the ‘Heating’ or ‘Cooling’ mode, you prevent your unit from constantly cycling between modes, reducing energy waste and extending the lifespan of your HVAC system. Plus, you have better control over the temperature, allowing you to fine-tune it to your comfort level.

Benefits of Manual Control

Energy Savings: Using ‘Heating’ or ‘Cooling’ mode can significantly reduce your energy consumption, leading to lower utility bills.

Increased Comfort: You’ll experience more consistent and comfortable indoor temperatures without the abrupt temperature swings that ‘Auto’ mode can create.

Extended Equipment Life: Less wear and tear on your HVAC system means it’s likely to last longer, saving you money on costly repairs or replacements.

Environmental Impact: Reduced energy usage contributes to a smaller carbon footprint, helping the environment by conserving resources and reducing greenhouse gas emissions.

Finding the Right Temperature

To maximise energy efficiency, it’s important to set your thermostat to a temperature that suits your comfort without overburdening your HVAC system. Here are a few tips:

Winter: During colder months, set your thermostat to the lowest comfortable temperature when you’re at home and awake. Lower it when you’re asleep or away to save even more energy.

Summer: In warmer seasons, raise your thermostat to a comfortable temperature when you’re home, and increase the difference between the indoor and outdoor temperatures when you’re away to save on cooling costs.


While the ‘Auto’ mode on your air conditioning unit may seem like a convenient choice, it often leads to wasted energy and higher utility bills. By opting for the ‘Heating or cooling’ mode and manually setting your desired temperature, you can achieve better control, enhanced comfort, and significant energy savings.

So, the next time you reach for that thermostat, remember that you have the power to make your home more energy-efficient and environmentally friendly simply by choosing the right mode. Say goodbye to the ‘Auto’ mode and hello to a more comfortable, eco-conscious living space!
