Types of Mini Splits: Ceiling Cassettes, Wall Mounts, & More

Types of Mini Splits | Total Home Supply

If you’re on the hunt for a new HVAC system, you may have encountered the term “mini split” several times throughout your research.

So, what is a mini split? A mini split is an efficient HVAC system that can provide both heat and air conditioning. It consists of an outdoor unit (called a compressor) and a single or multiple indoor units.

Unlike central heating and air conditioning systems, mini split systems do not require ductwork to operate. This makes them an appealing option for those who do not have existing ducts installed in the home.

Even if you already have ductwork installed, mini splits can be an attractive option for you. From their easy-to-install design to supreme energy efficiency, mini splits come with a multitude of benefits for businesses and homeowners alike.

But like most HVAC systems, there isn’t a single best type of mini split. We’ll explain the various mini split types to help you find the best mini split system for you, focusing on single vs multi zone mini splits, and the 7 different types of systems which include mini split ceiling cassettes and wall mount units.

Single vs. Multi Zone Mini Splits

Mini splits can be categorized as either single zone or multi zone mini splits.

Single Zone

Single zone mini split systems are designed to heat or cool a single room or “zone.” They consist of one outdoor compressor and one indoor unit.

Multi Zone

Unlike single zone mini splits, multi zone mini splits are designed to heat/cool multiple rooms or zones in a home. These systems consist of a single outdoor compressor and up to 8 indoor units.

Types of Mini Splits

While mini splits can be categorized as either a single zone or a multi zone, there are many other different types of mini splits available. Here, we’re giving you 7 different types and our recommendations, but our main focus will be on mini split ceiling cassette vs wall mounts.

1. Ceiling Cassette

Ceiling cassette mini splits consist of an outdoor unit and an indoor unit that mounts on the ceiling. The ceiling mounted design makes them a good alternative for those who want to keep their indoor unit out of sight, out of mind. As a bonus, the ceiling mounted design delivers a wider air flow than that of wall mounted units.

Wall mount mini split systems are the most common type of mini splits. They are installed high up on a wall and pump out air into a room or area. Wall mount mini splits are ideal for all types of rooms and are also the least expensive mini splits on the market.

There are many different styles of wall mount mini splits available. The LG Art Cool is particularly unique since its indoor unit is hidden behind a picture frame, while the Daikin Emura offers a sleek, low-profile design.

  • Hello,

    Are there any setups where the compressor goes outside and mini-split portion sits in a widow (like a regular window AC unit)?

    Thanks,

    Robert

  • Hi, im looking for a 3 ton, 3 zone mini split, with an 18000btu ceiling cassette, and 2 9000btu wall mounts. I cant find anywhere, i cant find any ceiling cassette and Wall mount combination anywhere. Do they make them?

  • can a concealed or ceiling cassette work with any type of ceiling or just dropped ceilings? We would use them in bedrooms below attic.

    • For use in a bedroom ceiling below an attic, special framing would be required as the unit is wider than a standard joist bay.

  • How far can the lines travel from the compressor to reach other rooms of the house for wall mounted units? Would they be in the wall or wrap around the house?

    • Maximum line length varies based on the specs of the system you are using. Lines can be run in the wall or on the outside of the house.
