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.
