How Big is a Ductless Mini Split for My Rochester, NY Home?

Generally, a high-wall air handler for a ductless mini split system is a foot high, a little over two-and-a-half feet wide, and 9 inches in depth. Heat pumps are nearly two feet tall, one foot in depth, and around 32 inches wide. '

We get asked a lot about how big a mini split is, and how it will look in customers' homes. 

These are great questions. If you’re about to invest your money in a brand-new HVAC system that should last for 20 years or more (with maintenance, of course), you want to know how it will impact the look and feel of your home.

We gave you a quick estimate already, but there’s more to it than that. In this article, we’re giving you a guide to the look and feel of a ductless mini split. You’ll get a sense of how big each component is, and how it will fit in your home.

Parts of a Mini Split System

Before we get into the dimensions of a mini split, you need to know the components in the system.

Outside the home, a heat pump controls the heat transfer process. It moves heat from inside to outside during the summer. Then, it transfers that thermal energy from outside into the home in the winter.

From there, an air handler inside the house circulates the air. It also dehumidifies as part of the air conditioning process. Coming from the air handler is a line set with a few wires in it; a refrigerant line that connects the handler and the heat pump, and a power cord.

Finally, a condensate line catches moisture as water vapor turns back into a liquid during the dehumidification process. This line drains that moisture to the outside of the house. Now that we’ve got our terms straight let’s get to the measurements. For this post, we’re using specs from Mitsubishi models. They’re the standard-bearer in the ductless world and the most common ones.

As we mentioned, the average wall-mounted air handler is 12x32x9 inches. And, a heat pump is 24x32x12 inches. That’s for an average heat pump for maybe one or two air handlers.

After that, they get a little wider — up to two feet deep instead of one. Others are still narrow but stacked twice as high.

Then, you have the floor, or low-wall, air handlers. These aren’t as common as the high-wall models, but they’re still used a lot. The average model is nearly two feet high, 29 inches wide, and about 8.5 inches deep.

What Does the Mini Split Look Like In My House?

Finally, let’s see how the mini split will look once we install it in your house. Of course, there’s no one design. That’s the beauty of these systems: We can configure them in whatever way suits your home the best. With that in mind, however, we can give you some ideas about how things fit.

Placing the Heat Pump

For starters, imagine the heat pump in place of a traditional air conditioning condenser. You may have it in the back or on the side of the house, close to the building. In most cases, however, it takes up much less room.

They’re not as tall, and certainly not as wide. Also, since they’re rectangular, there are more opportunities to get it in any small recesses in the shape of the house.

Installing the Air Handlers

Next are the air handlers. These do a great job of circulating air, so we have a lot of flexibility when it comes to where we place them.

If it’s treating just one room, we usually place a wall unit up near the ceiling and in a corner. It only needs to be six inches from the ceiling and five inches from the edge. This positioning tends to keep it out of the eye line. And, in the corner, it’s even less noticeable. If you have an open floor plan, we may center it more so that one unit treats the whole area. On the other hand, a low-wall or floor unit mounts close to the floor. Usually, these go in a corner, as well.

Placing the Line Set

Finally, we connect the system with the line sets. Each air handler gets its own set, and they all need to meet and reach the heat pump outside. While there may be a lot to connect, we also have a lot of options.

Since these are all small flexible, it’s much easier than routing ductwork. In many cases, especially with new construction or renovations, we simply run the lines behind the walls and in between the rafters. From there, we run the line out to the heat pump. If we can’t run it through the walls, we’ll work on the air handler placement so that the lines take up as little room as possible. That goes for the outside of the house as well as the inside. Fortunately, the casings for the lines come in a variety of colors. And, they’re paintable. So, it’s easy to either have them blend in or act as accents to a room.
