If you rely on a mini split to cool your home during the warm spring and summer months, you’re likely to have a few questions. And that’s especially true if you’re new to this type of HVAC system.

At the top of your list is whether or not you can run a mini split all day long.

There’s no right or wrong answer to this question, and here’s why: you can run your mini split for as long or short as you want.

For example, when temperatures reach triple digits, you may need to run your mini split for hours on end to keep your home cool.

Conversely, if you’re willing to set your thermostat a bit higher, your mini split system will cycle on and off throughout the day.

Here are some points of consideration:

  • It won’t harm your system: Many people worry about running their mini split all day long because of the strain it puts on the system. This shouldn’t be a concern, as mini splits are designed to work in this manner.
  • Your mini split can adjust itself: For example, rather than turn itself on and off, your mini split can may have a feature that allows the fan speed to adjust automatically. This makes for a more energy efficient system, which will save you money.
  • You can use a smart thermostat: This is one of the best ways to control how often and for how long your mini split runs. Maybe you want to turn up the cool air at night while you’re trying to sleep, but turn it down during the day when you’re not at home. With a smart thermostat, you can program it to your exact specifications.

What if Your System Won’t Turn Off?

Maybe you don’t want your mini split system to run all day long. You may come to find that it’s running continuously for no reason. That’s a problem.

There are many potential culprits, including but not limited to faulty wiring and/or a refrigerant leak.

If you want your system to turn off but it won’t cooperate, it’s time to contact a professional. Letting this problem linger and simply hoping for the best will cost you time and money. Not to mention the fact that it can result in a hot and uncomfortable home.
