Ductless air conditioning systems are popular in buildings where a traditional central system isn’t practical. One big name in the HVAC world is Mitsubishi, which has a ductless system.

In this article, we’ll look at exactly what a Mitsubishi ductless system is, how it works, and why it might be a better option than a traditional HVAC unit.

What you’ll learn in this article:

  • What a Mitsubishi ductless system is
  • Types of ductless units
  • What is the best type of system for you
  • Benefits of ductless systems
  • Disadvantages of ductless systems
  • How to properly size a unit
  • Next steps for your on ductless unit

What is a Mitsubishi Ductless System?

A ductless HVAC system runs off individual air conditioning units rather than a central furnace/cooling system. As you might have guessed, a ductless system has no ductwork!

A Mitsubishi unit uses the same process as standard HVAC units to heat and cool air. The process is:

An outdoor compressor pumps liquid refrigerant through tubing into the indoor unit.

The indoor unit has a coil, which the refrigerant passes around.

As it does so, it turns into a gas and cools the surrounding air by absorbing heat.

A fan blows the cool air around the room.

The refrigerant, as a gas, passes back into the outdoor unit, where it’s converted back into a liquid.

In the process, it loses heat, which it expels using a fan.

So, a ductless system works just like a standard HVAC unit, except each unit has its own indoor and outdoor unit. Because of this, that means you don’t need ducting running throughout the property circulating air.

Types of Mitsubishi Ductless System

Ductless systems generally come in two types: single-zone and multi-zone. These are fairly obvious distinctions, but let’s take a look at them in more detail.

Single Zone Ductless System

A single-zone ductless system has one indoor and one outdoor unit per space. The systems are easy to install and have very little impact on the property. The Mitsubishi Comfort System can be single zone or multi-zone, depending on your needs.

Multi-Zone Ductless System

A multi-zone system has a single outdoor unit and multiple indoor units. Each indoor unit having individual controls gives you plenty of flexibility.

The Mitsubishi mini-split can power up to 5 indoor units, although larger models can power up to 11.

As you might imagine, they do need connections, but these aren’t as invasive as installing ductwork. Using small pipes, they are easy to install quickly and efficiently.

Which Type is Best?

The type of Mitsubishi ductless system you choose entirely depends on your household needs. For apartments, a single zone system might be enough.

Larger properties would benefit from a multi-zone system, particularly one that can power 11 indoor units. You might think a traditional HVAC system would be fine in this situation, but a ductless system still offers multiple benefits.

The Benefits of a Ductless System

There aren’t any reasons why a ducted HVAC system would be a better choice if you don’t already have the infrastructure in your home. Even so, here are the reasons why a ductless system is a good idea.

Easier to Install

A Mitsubishi unit is easier to install than a ducted HVAC unit, simply because you don’t need ductwork. Even multi-zone systems are easier to install. The connecting conduits can stretch up to 50 feet, giving you plenty of flexibility, even in larger spaces.

They Offer Individual Room Control

One major disadvantage of ducted HVAC systems is that they give out the same temperature air across the property. This situation might be fine when it’s really hot or really cold but is unnecessary the rest of the time.

Plus, it’s unnecessary cooling rooms that you don’t use.

A ductless system allows you to individually control the temperature of each space through its indoor unit. This feature helps to save both energy and money.

Flexible Placement

As a ductless system doesn’t require pipework in the walls, you have more flexibility with placement. They can be hung from ceilings or walls or stood on the floor.

More Energy Efficient

Something like a Mitsubishi mini-split is more energy-efficient compared to a traditional HVAC system.

Along with the individual temperature control mentioned above, you have the advantage of the system not losing temperature as the air travels through the duct.

For example, air traveling from the central unit through 100ft of ducting will lose its heat through the leakage. You avoid this by not having ducts, meaning the whole system is more efficient.

Maintenance is Easier

It should come as no surprise, but ductless system maintenance is much easier. The indoor and outdoor units are usually more accessible, meaning technicians can reach them more easily.

And, you don’t even have to worry about maintaining ducts. While they’re not prone to damage, regular cleaning ensures the air they circulate is clean and free from bacteria.

With a ductless system, you don’t need to worry about these issues. This assurance makes them good for people with respiratory issues and everyone.

Disadvantages of Ductless Systems

It’s necessary to mention the potential drawbacks of ductless systems. A Mitsubishi comfort system is generally a great idea, but there are some things to consider.

Price

Ductless systems are more expensive than ducted HVAC units. They can cost around 30% more on average, or even more if you choose a high-end model.

While this can be a difficult cost to absorb upfront, it does equal out in the long run.

Choosing the Right Size Unit

Also, it’s vital to choose the right size unit for your space. This problem isn’t as much of an issue with ducted HVAC units.

With a ductless system, oversized or incorrectly placed units can short-cycle, meaning they don’t circulate air or control humidity properly.

Conclusion

Overall, a Mitsubishi ductless system offers numerous advantages over ducted HVAC units. They help to save energy, are more flexible, and offer individual temperature control.

If you’re able to deal with the upfront cost, they’re worth the money. So, if installation sounds like a good idea, contact us for assistance. We can advise on the best unit to choose and proper placement, allowing you to get the most from your new unit.
