What to Know Before Putting a Ductless Mini Split on the Wall

There are many different ways to install a ductless heating and cooling system, including in the ceiling, on the floor, and on the wall. Wall-mounted ductless units tend to be the most popular among New England homeowners due to their affordability, superb efficiency, and excellent temperature control. If you are considering getting a ductless mini split on the wall, here are some things to know first and how to get experienced help from an HVAC contractor near you.

Ductless Mini Split

Are Your Walls Thick Enough?

Ductless cassettes are by no means heavy, but it’s still important to make sure that the structure of your walls is sturdy enough to support them. Each indoor cassette weighs roughly 8 lb. and must be secured to a stud in the wall. You will not be able to successfully install a wall mounted ductless unit on only drywall or panels. If your walls are thin or otherwise do not offer the necessary support for an indoor ductless cassette, you may still be able to enjoy the many advantages of ductless heating and cooling by opting for a different type of mount.

Will Floor or Recessed Ceiling Units Work Better For Your Home?

Although wall-mounted ductless HVAC is more popular than other types of installations, you should review all of the options available to you to make sure that wall mounts will provide maximum efficiency, comfort, and energy savings. Look at both recessed ceiling ductless and floor mounted units and compare and contrast the benefits and disadvantages of the different types of installations to determine the best fit for your home and lifestyle.

Where Do You Need the Most Heating and Cooling Power?

Consider the layout of your home and which rooms you will need the most heating and cooling in. You should also think about which rooms you use the most often or which rooms are used by the most people, as well as which rooms are open to other areas of the home.

For example, if you have a dining room that connects to both your kitchen and a den, the dining room may offer the best placement to cool all three rooms. If you were to put the wall-mounted cassette in the den, the dining room might get cool, but the air would likely not reach all the way to the kitchen.

Which Wall In Each Room Works Best For a Ductless Cassette?

You should also consider which wall you want to have the indoor cassette installed on in each room you decided to have a ductless unit put in. The wall placement of an indoor cassette can affect its air flow and efficiency, potentially using more energy than needed to reach the desired temperature. Don’t place an indoor ductless cassette by a window or door, since hot and cold drafts coming in from outdoors can compromise the efficiency and efficacy of your HVAC system.

Instead, your indoor unit should be placed on a blank wall, about two-thirds of the way up the wall from the floor and 8″ to 12” down from the ceiling. This allows plenty of air to be drawn into the cassette and for even air flow output throughout the room. It also allows technicians to access the unit to clean it or make repairs.

Do You Need a Professional to Install a Ductless Mini Split on the Wall?

Installing a ductless mini split on the wall is quite unlike installing a window AC and requires the help of a professional HVAC contractor. DIY ductless installation is dangerous and at best can be extremely costly and provide you with little to no extra energy savings. At worst, DIY installation can result in critical injuries or even death due to electrocution, chemical exposure, etc.
