Which Mitsubishi Mini-Split Should You Get?

Outdoor Mini-Split Condenser Units

There are lots of HVAC brands that make mini-split systems, but Mitsubishi is one of the best-selling (if not the best-selling) brand in the country.

Why? We think it might have something to do with the reliability and the variety in their product line.

Mitsubishi mini-splits are actually made by Mitsubishi Electric Trane HVAC US (METUS, for short), which is a subsidiary of the Mitsubishi Electric Corporation. And yes, that means your Mitsubishi unit, regardless of which type of mini-split you have installed, is also a Trane-branded product.

That's good! We like Trane and always have. They produce industry-leading HVAC equipment that has a well-deserved reputation for quality and longevity.

If you're considering a Mitsubishi mini-split system for your addition, renovation, or supplemental HVAC project, there's really no way to go wrong.

The thing is - and we've seen this a lot when discussing mini-splits with people who haven't ever had one - there are lots of options to choose from. And they don't all look like this:

Standard Wall-Mounted Mini-Split Unit

Let's take a look at all the different Mitsubishi mini-split options you can choose from.

1. Just conditioning a single room? Put it on the wall, the ceiling, or the floor.

When it comes to single-zone mini-split systems, most people are familiar with wall units. They're the most common type of mini-split to see out in the wild. But Mitsubishi's product line doesn't limit you to wall-mounted systems.

Check out this ceiling cassette.

Mitsubishi Mini-Split Ceiling Cassette

It does the same thing the wall-mounted unit does, except that it's flush with your ceiling. This works well when:

  • Your room doesn't have the right clearance to install a wall-mounted unit, or
  • You or someone in your household doesn't like the looks of the wall-mounted system

There are actually two different varieties of ceiling cassette models. One type blows in a single direction, which makes sense for smaller spaces where the cassette is installed near where the ceiling meets the wall. Another type blows in four different directions. It's often the best choice for larger spaces and when you want the cassette positioned near the center of the room.

Since the cassette blends right in with the ceiling, most people won't even notice it. If it wasn't making you comfortable 24/7, you might even forget it was there.

There's also this floor-mounted model.

This is a good option if you lack the wall clearance for a more typical-looking unit. It's also great if you want your mini-split to be more flush with the wall or if you're particularly concerned about heating in a room with high ceilings.

After all, warm air rises in an otherwise cold room. You'll want that heat closer to where people actually are (the floor, not the ceiling).

And last but not least, there's…

Mitsubishi Wall-Mounted Mini-Split Unit

This is the "classic" mini-split indoor unit. If you weren't already aware of the floor and ceiling options, this is probably what you'd expect your system to look like. It's still the most common type of mini-split indoor unit that we install in Atlanta-area homes.

2. Need to cool and/or heat multiple rooms with your mini-split? You've got options.

Did you know that a single outdoor mini-split unit can pair with multiple indoor units?

That's right! You can heat and cool different rooms with different indoor units with just a single condenser coil outside your home. A single outdoor unit can serve up to eight indoor units in some applications!

This configuration gives you the benefits of multi-zone heating and cooling while still only having one HVAC system. Pretty neat, right? Say you need supplemental AC for hot upstairs rooms. You could install a Mitsubishi mini-split system where there were AC units in each bedroom, all of which paired with a single outdoor unit.

If you're doing this for more than just a few rooms, you might actually need two outdoor units to pair with however many indoor units you have.

Except that you might not.

Stacked Mini-Split Outdoor Condenser Unit

MItsubishi makes this "stacked" outdoor unit for those times when you require more heating or cooling capacity. It doesn't take up any more space on your property than a single one would.

But you know what? Mitsubishi offers yet another way to do multi-zone heating and cooling:

Ducted mini-split systems

Yep. Not all mini-split systems are ductless. The outdoor unit will look the same as with the ductless systems. The indoor part of the system includes an air handler that resembles what you see with standard split HVAC systems.

If you don't like big wall units or just don't want a big piece of indoor equipment (whether it's floor-mounted, ceiling-mounted, or otherwise) in your rooms, this is a good option.

The system's evaporator coil lives inside your attic, crawlspace, or basement. Ducts branch off from that unit to send (and return) air to each room that needs it.

Does that sound a lot like a standard HVAC system? Well, it is.

Mini-split systems, on the other hand, usually have a smaller physical footprint compared to most residential systems (they're "mini," after all). The duct runs on most units tend to be short, but there's even a standard-size air handler for installations that require longer duct runs.

You might get more flexibility with this kind of mini-split system. The trade-off is efficiency loss. Ducts, by their very nature, reduce efficiency because the system sheds energy as air travels through them.

Does that mean the system is inefficient? No way! It's just somewhat less efficient than a ductless system, which uses way less energy than a regular split HVAC system with ducts.

Mitsubishi really does offer mini-split options for every part of your home.

Since most homes in our area are built to accommodate standard ducted split HVAC systems, that's what most homes have. Usually, homeowners only install mini-split systems when they're making some sort of change: a renovation, addition, or conversion of a detached shed or garage.

But Mitsubishi's product line has so much variety, you could actually outfit your entire house with mini-split equipment. If you wanted to.

The point to all of this? When you're considering a mini-split system for any part of your home or your property, there's definitely a way to get what you want.
