What Is a Single-Zone Mini Split?

Mitsubishi Single-Zone Mini Split Solutions
When you need to add heating and cooling to a single room, such as a small office or an addition to a home, a single-zone ductless mini split is your best bet. These convenient appliances are capable of efficiently heating and cooling a room while minimizing the need for major construction during the installation process.
Mitsubishi mini splits are some of the best and most trusted machines on the market, making them the perfect option for your home, rental, or business space. And since these units consist of a single indoor unit and an outdoor condenser, they’re easy to add to any existing space while remaining discreet.
Benefits of Single-Zone Mini Split Systems
Mitsubishi single-zone mini splits are convenient, versatile, and efficient. These units are ductless, meaning they don’t require any major ductwork to function1. Instead, they use smaller tubing and cables to move air from the condenser to the indoor air handler. As a result, mini split installation is comparatively quick and easy, and units can be positioned just about anywhere in a room. It also helps that mini splits take up very little space, both indoors and outdoors.
Because mini splits are capable of both heating and cooling, owners don’t need to spend time sourcing two different HVAC units. Instead, you can get both in one neat package. After installing a single-zone mini split, you may also notice your energy bills start to go down. That’s because they’re more energy efficient than their bulky, duct-using counterparts.
Mini splits also provide higher indoor air quality, thanks to the lack of combustion in the heating and cooling process2. Finally, no ductwork means no need to pay for professional service to clean those ducts and replace the single, overworked filter.
Our Single-Zone Mini Split Installation Process
Installing a single-zone ductless mini split is simple and painless. Our expert Mitsubishi Electric Elite Diamond technicians will first identify the ideal location to mount the condenser unit and air handler. Then, they’ll create a pathway through the wall to connect the units together, checking for obstructions like pipes and ducts along the way.
Once the pathway is clear, they can mount both indoor and outdoor units and go about connecting all pipes, drainage, and controls, linking both systems to one another. Everything is then securely fastened and tested to ensure full functionality.
