When your mini split suddenly stops working, it can naturally cause you to panic.

As efficient as mini splits are, they can only handle temperature extremes to a degree one way or the other.

Should the temps push the mini split further than it can go, then the mini split is either going to reduce operating efficiency[AE1]  and capacity or even stop working altogether.

So how cold is too cold for a mini split and how hot is too hot?

Well, that depends on the model.

As with phones, computers, and video game systems, ductless mini splits get better and better as technology evolves and newer models are introduced.

Shortly, we’ll present some of the most extraordinary mini splits that can handle high heat and low, cold temperatures.

On average though, a mini split typically works at temperatures as cold as five degrees Fahrenheit (which is -15 degrees Celsius) and up to 115 degrees Fahrenheit (which is 46 degrees Celsius).

A bad snowstorm is in the forecast, and you have to admit, you’re quite nervous. You’ve already run out and bought supplies, and you’ve since battened down all the hatches to wait out the storm.

You don’t want to go without hot air during what will surely be some of the coldest days of the winter, but you also don’t want your ductless mini split system to get overburdened and possibly stop working.

Should you turn off your mini split in a snowstorm?

Not necessarily, but there are other things you should do instead. Here’s what we recommend.

Turn On Defrost Mode

Most mini splits include a defrost mode, which may or may not be activated by default.

Defrost mode is designed to prevent the accumulation of ice on the coils and other internal components of the mini split system.

How does this work? The mini split has a thermostat that monitors the temperature. If the temps are too close to freezing and thus th

This is going to be your first winter with a ductless mini split system, and you honestly couldn’t be more excited. You know how costly it can be to run a traditional HVAC heating system like a furnace or a heater, which is part of why you made the switch.

However, you’re not sure how often you need to operate your mini split system come the wintertime. Does it need to be on all the time? Only some of the time?

You don’t want to push your mini split too far in the first year, but you don’t want to be left shivering either. So what’s appropriate?

You should not turn off your mini split in the winter, that’s for certain. Doing so will make your house a frosty ice palace in a hurry.

Rather, you should run the mini split about as often as you normally do, maybe somewhat more frequently if it’s an especially freezing cold winter.

This winter looks like it’s going to be an especially cold one. You’re confident that your ductless mini split system can get you through, but what can you do ahead of the season to help your mini split run at its best?

Here are some of our best practices for preparing a mini split for the winter.

Elevate the Compressor

We talked about this in another recent post on the blog, but when your outdoor compressor is bogged down with snow, it doesn’t work well.

The heat that the compressor generates will go towards melting the snow around it first and foremost. Whatever heat is left is then pushed into your home, which might not be enough for the house to feel toasty warm.

You need to elevate the compressor at least 24 inches above the ground. Before the first snow of the season (if you have time), you can pour more concrete to elevate the height of the current concrete slab.

You can also take old wooden milk carto

You’re all about saving money, which is why you’ve strongly considered ditching your current HVAC and upgrading to a ductless mini split system.

Before you can decide with confidence though, you must know what kinds of heating and cooling costs you’re going to incur if you get a mini split system installed.

For instance, does it cost more to heat your home with a mini split or to cool it?

Well, for starters, a mini split can cool and warm a home a lot more economically than a traditional central air conditioner or heater.

As for how much it costs to cool and heat using a mini split, it’s about the same.

For a standard ductless mini split system that runs on 1,758 watts and has an output of 6,000 British thermal units or BTUs that you’re paying on average $0.13 a kilowatt-hour or kWh to run, the cost of operating a mini split to heat or cool would be $0.23 an hour.

If you run the mini split for 10 hours a day, that’s $2.3 a day.
