Answer:
In our experience, it’s generally a good idea to leave your Fujitsu mini-split on most of the time, especially during extreme weather seasons. These systems are designed to maintain a consistent temperature, which can actually use less energy than turning them off and on repeatedly. Many of our customers find that their mini-split runs more efficiently when left to operate steadily because it avoids the energy spikes caused by frequent starts and stops. Of course, the specific settings and use depend on your home, lifestyle, and energy goals, but as a rule of thumb, mini-splits thrive on maintaining comfort over the long term.

Leaving your Fujitsu mini-split on constantly doesn’t mean it will run at full blast. Thanks to its inverter technology, the unit can modulate its speed to maintain a set temperature, using far less energy than conventional HVAC systems. By allowing it to run continuously, the mini-split prevents large fluctuations in room temperature, which is particularly helpful for comfort and reducing wear and tear on the system.
In our line of work, we often recommend using the “auto” mode on your Fujitsu system for optimal performance. This mode allows the unit to adjust heating or cooling based on the room’s needs. However, if you’re leaving the house for an extended period, setting the system to a slightly higher or lower temperature (depending on the season) is a smart way to save on energy costs while still keeping your home comfortable upon return. Every home is unique, and the decision to leave your unit on 24/7 should also consider factors like insulation and energy rates in your area.
