Mount Up: All About Mini Split Mounting Brackets

mini split mounting brackets

Mini splits are an efficient and flexible cooling option for any home. Since they don’t need ducts to carry the cool air, they are much more efficient than conventional ducted AC systems, and best of all, they can be placed just about anywhere!

This makes mounting brackets one of the key accessories when it comes to ducted mini splits. In this guide, we explore the different types of mini split mounting brackets, to give you different options for placing and installing your mini split.

What is a Mini Split Mounting Bracket?

As the name illustrates, a mini split mounting bracket is a brace that physically holds the ductless mini split outdoor unit. The bracket connects to the wall or other part of the house and supports the weight of the unit, holding it firmly and securely in place.

Are Mounting Brackets Required for Mini Splits?

No, but they are strongly recommended. While a mini split outdoor unit can be placed on a flat, level surface, a wall mount bracket, stand, or pad should be used. These keep the mini split secure and prevent wind and weather risks. 

What Are the Different Types of Mounting Brackets?

First, we need to distinguish between mounting indoor and outdoor units. Indoor units contain the air handler and are installed inside the house, while outdoor units house the compressor and are placed on the outside.

Indoor mounting brackets

Mounting brackets for indoor units can be divided into the different kinds of mini splits:

Wall mount brackets – designed for wall-mounted and floor-mounted mini splits, since both connect to the wall. These are almost always included with the indoor unit at the time of purchase.

Ceiling cassette mounts – these hold ceiling cassette units. They are not brackets per se, but consist of an entire housing for the recessed unit, as well as grille cover. While some third-party mounting brackets exist for these units, a customized field supplied solution is generally used. The units contain mounting points that are used with screws, threaded rod, or other supports.

Suspended ceiling mounts – these apply to ceiling suspended mini splits that are typically used in commercial spaces. They are not compatible with false ceilings.

Outdoor mounting brackets

The outdoor mounting bracket holds the compressor securely in place. Since it is exposed to the elements, it is typically more robust than indoor mounting brackets, and uses materials designed for outdoor exposure, corrosion resistance and longevity.

Outdoor mounting options can be classified into two types:

Outdoor wall mounts – these brackets allow the compressor to hang from an exterior wall.

How to Choose the Right Mini Split Mounting Bracket

1. Mounting location

The type of mini split and the installation location determine the type of mounting bracket you need, whether it’s on the wall, suspended on the ceiling, or placed on the ground.

2. Weight capacity

Mini split mounting brackets have a maximum weight capacity. Generally speaking, the higher the mini split BTU, the heavier the unit is. Make sure your chosen mounting bracket can handle the weight of the unit.

3. Materials

Not all mini mounting brackets are created equal. Some use stainless steel, while others use alloys for improved durability. For outdoor mounting brackets, make sure they are constructed from materials that can withstand the elements. 

4. Weather

It is imperative that a heat pump mini split in a snowy climate be kept clear of snow for proper functionality. That means either mounting the unit on a wall above the average snow line or using a mini split stand tall enough for the amount of snow expected. 

Wind is also a critical factor to consider. Make sure that you select a mounting solution that will keep your outdoor unit out of strong wind gusts and that the mounting solution is hurricane rated if required in your area.

4. Compatibility

Some mini splits manufacturers use proprietary mounting, so their mini split units can only be used with factory produced brackets. Refer to your owner’s manual for the mounting specifications, and whether the mini split is compatible with third-party brackets and what mounting hardware may be needed.

At Total Home Supply, we carry a range of mini split mounting brackets and mounting accessories to suit your mini split. We also offer expert advice on what mounting options best fit your unit. Feel free to reach out and get your mini split mounted in no time!
