Fujitsu mini-splits are designed to fit the unique needs of your home. Fujitsu mini split systems can cater to the situation at hand because they’re focused on heating/cooling specific living spaces instead of being a one-size-fits-all solution for your whole home. They’re extremely customizable, energy-efficient, and easy to install. Whether you’re looking for a wall-mounted, ceiling-recessed, or ducted solution, Fujitsu split systems can fit your unique situation.

Fujitsu mini-split air conditioners aren’t always a perfect fit, but they do have their place in almost all applications. They’re great for hot & cold spots, renovations, new construction, replacement systems, and light commercial spaces.

Fujitsu’s split systems can come in air conditioning units or heat pumps. All the Fujitsu multi-zoned systems are heat pumps.

Fujitsu is an international leader in the ductless space within the HVAC industry. They compete head to head with other manufacturers like Mitsubishi & LG but Fujitsu is hard to beat in high efficiency & low temperature options. Fujitsu offers systems with up to 33 SEER, the highest in the industry. Fujitsu also offers plenty of low temperature options, with systems that can cover down to -15 degrees Fahrenheit. If you are a customer in a region that enjoys long, cold winters, Fujitsu's extra low temperature ductless systems are the best bang for your buck when considering cost & performance.

How To Find The Right Mitsubishi Mini Split

Fujitsu has multiple product lines that can heat or cool your home. Most likely, you'll stick to Mitsubishi's M-Series. One M-Series condensing unit (outdoor unit) can cool and heat 2400 square feet and connect up to eight indoor units. The M-Series is a full line-up of:

When using any of Mitsubishi's multi-zone outdoor units, you can use almost any combination of indoor units. If you'd like help finding the correct combination for your project, reach out to us.

Most of Mitsubishi's inverter-driven systems are certified by Energy Star. They're also up to 40% more energy efficient when you're comparing them to central HVAC systems. M-Series multi-zoned systems are ideal for supplementing a current system, new additions, or replacing a current system.

Mitsubishi's M-Series was designed for homeowners and small businesses.

How To Pick The Right Mitsubishi Condenser/Outdoor Unit

We routinely consult on ductless systems, and there are three main questions we ask when helping pick the right outdoor unit:

What's the overall size of the system?
Is it going to be the primary source of heat for your home?
What is the average winter/cold season temperature for your area?

Sizing Your System

You can find our calculator for sizing a room/home here. When you're sizing your mini-split system, make sure you add together the capacity of each indoor unit that's going to be connected to it.

Using Mitsubishi Mini-Splits As Your Primary Source Of Heat

It's important to make sure the outdoor unit is sized based on your needs. If mini splits are going to be your primary source of heat, it's prudent for you to oversize key individual units. Oversizing a unit doesn't work well for most traditional HVAC systems because they don't adjust their output based on the rooms/houses' needs. But since Mitsubishi mini splits use inverter-driven compressors, they constantly modulate their output based on the requirements of the room.

Slightly sizing up key indoor units in master bedrooms or living rooms could mean the difference between those areas not having enough heat/air conditioning on intemperate days.

Using Mitsubishi Mini-Splits In Extreme Temperature Climates

Mitsubishi innovated on the heat pump and pioneered Hyper-Heating technology (or H2i®). H2i® low-ambient heating technology is designed for cold climates that routinely dip below 20 degrees. Currently, Hyper-Heating units can produce 100% of their heating capacity down to -5°F - making them a viable heating source in low-temperature climates.
