Components
The Fujitsu ductless air conditioner has several key components that work together to provide efficient and effective cooling. The inverter-driven compressor is a crucial component, allowing for precise temperature control and energy efficiency.
This compressor is paired with a fan coil unit, which is responsible for circulating air throughout the space. The fan coil unit is designed to be quiet and compact, making it ideal for installation in a variety of locations.
The system also features a remote controller, which allows users to easily adjust the temperature, fan speed, and other settings from a convenient location.

Indoor Units for Heat Pumps
Indoor units are designed to be quiet and compact, usually wall-mounted or floor-standing, and can be installed in a variety of locations.
They can be either air-source or ground-source, with air-source units being the most common type.
Heat pump indoor units can be categorized into two main types: air-source and ground-source.
Air-source units are the most popular type and can be further divided into ducted and ductless systems.
Ducted systems use a network of ducts to distribute heated air throughout the home, while ductless systems use a series of wall-mounted units to provide direct heating.
Ground-source units, on the other hand, use a network of underground pipes to extract heat from the ground.
The efficiency of indoor units is measured in terms of their Seasonal Performance Factor (SPF), which is a measure of their ability to provide heating and cooling over a typical heating and cooling season.
A higher SPF indicates a more efficient unit, with some units achieving SPF values of up to 20.
Heat pump indoor units can also be controlled using a range of devices, including thermostats, timers, and remote controls.
These controls allow homeowners to adjust the temperature, fan speed, and other settings to suit their needs.

Outdoor Units for Zone Control
Outdoor units are the backbone of a multi-zone heating and cooling system, and selecting the right one is crucial for efficient and effective zone control. The number of zones you need will determine the size and type of outdoor unit you require.
You can choose from a variety of outdoor unit models, including wall-mounted, floor-mounted, ceiling cassette, horizontal ducted, and air handlers. Each type has its own benefits and may be better suited to your specific needs.
For a 2-zone system, a 20,000 BTU capacity outdoor unit like the MXZ-2C20NA is a good option. This unit can handle a total connected load of up to 24,000 BTU.
For larger systems, you'll need a unit with a higher BTU capacity. For example, the MXZ-3C30NA has a 30,000 BTU capacity and can handle up to 36,000 BTU in total connected load.
Here are some key options to consider:
These are just a few examples of the many options available, and the right choice for you will depend on your specific needs and requirements. Be sure to consult with a professional to ensure you select the best outdoor unit for your multi-zone system.
Condensation
Condensation can be a problem with AC units, especially if you run them on certain settings. This can lead to condensation dripping from the unit.
Running the unit on its "dry" setting can cause condensation, as I learned from a technician.
You can avoid this issue by not running the unit on its "dry" setting if possible.
Keeping an old towel under the unit can also help save your belongings from water damage, just in case.
This is a lesson I learned firsthand when my installers had to re-do a drain pipe after installation due to condensation issues.

Choosing the Right System
Choosing the right Fujitsu ductless air conditioner system is crucial for optimal performance. You can find a calculator for sizing a room or home on the Fujitsu website.
To ensure your system is properly sized, add together the capacity of each indoor unit that will be connected to it. Slightly sizing up key indoor units in master bedrooms or living rooms could mean the difference between those areas not having enough heat or air conditioning on extreme days.
If you're planning a multi-zone system, you'll need to choose the right outdoor unit. Here's a breakdown of the available options:
Sizing Your System
Sizing your system is a crucial step in choosing the right mini-split system for your home. Make sure to add together the capacity of each indoor unit that's going to be connected to it.
A good rule of thumb is to slightly size up key indoor units in master bedrooms or living rooms, as this can make a big difference on intemperate days.
To give you a better idea, here's a rough guide to help you size your system:
Price
Central air conditioning can be a significant investment, but it's not necessarily the only option.
Installation of central air with ductwork can easily run upwards of $10k, especially in old houses.
In contrast, ductless mini splits are often a more affordable choice.
The cost of a Fujitsu ductless mini split is quite reasonable, especially when compared to traditional central air systems.
The total cost of our ductless air conditioner was $5k, including the unit, parts, labor, and installation.
This price tag is a fraction of what we would have paid for a traditional central air system, especially considering our old house's radiator heat system.

Location
Placing your mini split in a central location can save you money, as it reduces the amount of piping needed. This is especially true if you can install it near an exterior wall.
The location of your mini split can also impact how well it cools your home. You'll want to choose a spot where the air can spread throughout the house easily.
In a two-family apartment, a single ductless mini split can be sufficient, especially in a modest-sized space. However, if your apartment has many doors, you may need to use a fan to circulate the cool air to all rooms.
Installing your mini split near a gas stovetop, like the author did, can be problematic. The AC can blow gas all over the stove when it kicks on, which isn't ideal.
In some cases, you may need to turn off the AC when using the stovetop, which isn't the most convenient solution. However, this isn't necessarily a fault of the mini split unit itself.

Cons
The Fujitsu ductless mini split is still more expensive to install up front than a window unit, with costs that may deter some folks.
The up-front cost may be a significant factor, especially if you can get a window unit for $150 or less.
Choose your ductless mini split's home carefully, as it's an investment that requires consideration.
The dry settings on the Fujitsu ductless mini split are a great feature, but they're not available to everyone, as the author now lives without them.
