Installing a mini-split system isn’t a do-it-yourself (DIY) job. There’s a lot that goes into the process, including key decisions in regards to location.

It’s your goal to install your system in a manner that allows for the best circulation. When you do this, you end up with an energy-efficient heating and cooling system that provides you with comfort year-round.

Installation Questions to Answer

Even if you plan on hiring a professional to install your mini-split, it still makes sense to answer as many questions as you can on your own.

Here are several that will point you in the right direction:

1. Can a ductless heat pump be placed on the north side?

Before we get to the answer, remember this: you don’t want to choose just any location for your outdoor unit. You want to choose the location that allows your system to work at peak efficiency at all times.

With that in mind, yes, you should place the outdoor unit on the north side of your home. This is where it’ll get the most shade.

Should the north side not be possible for any reason, search for another shady location, such as under a deck. Just make sure there’s enough clearance for proper airflow and to access the unit for regular maintenance.

2. Where is the best place to install indoor air handlers?

This varies from home to home and depends on a variety of factors, such as size, the system you choose, the number of zones, and the layout of your rooms.

As a general rule of thumb, you want to install indoor units on an exterior wall. This allows for the most convenient connection to the outdoor unit.

Note: you can install wall-mounted units on interior walls, but it’ll take more planning to figure out how to run refrigerant lines to the exterior of your home.

3. How can you improve circulation indoors?

Just the same as a conventional HVAC system with ductwork, you must give your mini-split the space necessary to circulate air throughout your home. And that means keeping indoor air handlers clear of obstacles.

For example, if you install a wall-mounted unit in your bedroom, don’t cover it (not even partially) with furniture, plants, or any other type of decor. This reduces the ability for air to reach your room.

4. Do ductless mini-splits dehumidify?

The short answer is yes. You’ll want to verify this before you purchase your system, but most mini-splits are designed to dehumidify your home during the cooling process.

Depending on the features, you may even be able to set your system to do nothing more than control humidity.

When you install your outdoor unit and indoor air handlers in the right place, with circulation in mind, you’re in line to make the most of your system.
