Top Mini Split Inverters for 2022

Ductless mini splits are a great way to heat and cool indoor spaces without the mess and complications of traditional HVAC systems. For most mini splits, installation only requires a small hole to pass the power, refrigerant, and condensation line between the indoor and outdoor unit.

However, mini splits can also cost a pretty penny in utilities, particularly multi-zone units that heat and cool multiple rooms. Thankfully, homeowners can cut down those dreaded monthly bills with mini split inverters.

What is a mini split?

A mini split AC unit has the same function as other air conditioners: cooling your home. The main difference is that mini split air conditioners do not rely on ducts, which is why they are also referred to as “ductless air conditioners.”

The cooling (or heating) process happens via two components: an indoor and an outdoor unit. The indoor unit blows the warm air over cold evaporator coils containing refrigerant, which absorbs that heat from the air, and runs it to the outside unit. Through the compressor, the refrigerant dumps the heat pulled from your home’s air.

What is a mini split inverter?

Within the mini split systems, there are two types of compressors: rotary and inverter. 

A rotary compressor runs on a fixed capacity, while a mini split inverter uses only enough power to reach and maintain your set temperature, and then idles at that setting until more power is needed. This results in more efficient operation.

Advantages of Mini Split Inverters

Reduced power consumption

• Inverters have a variable electrical consumption based on their workload.

Longer operational lifespan

• Since the compressors are more efficient and don’t have to work as hard, mini split inverters tend to have a longer lifespan than conventional rotary units.

Faster cooling

• Mini split inverters start off strong, then gradually decrease the power level as the room temperature goes down. This means faster and more consistent cooling.

Long-term savings

• Depending on the appliance, inverter-equipped units can be up to 27% more efficient than traditional appliances, which translates to lower utility bills in the long run.

Our Recommended Mini Split Inverters for 2022

Single-zone mini-split inverter:  

Daikin FTXV09AVJU9 / RXT09AVJU9 Aurora Series Single Zone Mini Split System – R32

This EnergyStar certified single-zone mini split system delivers 9000 BTUs of cooling and 10,900 BTUs of heating through its reverse-cycle heat pump – perfect for spaces up to 450 sq. ft. 

With Inverter Technology, it’s capable of reaching impressive energy efficiency ratings of 21.0 SEER2, 12.2 EER2, and 10.2 HSPF2. Additionally, it uses R32 refrigerant, which has a greatly reduced GWP (Global Warming Potential) compared to older HFC refrigerants. 

With Low Ambient technology, this unit can efficiently cool spaces down even when temperatures plummet to -4°F with an air adjustment grille (KPW937F4). Conversely, with a drain pan heater, it can continue providing heat even when outdoor temperatures hit -13°F. 

Other features include Econo and Stand-By and fan-only modes, as well as advanced deodorizing functionality to trap microscopic particles that cause odor.

Dual-zone mini-split inverter system:

Friedrich FPHMR18A3D Floating Air Pro-X Two-Zone Mini Split Air Conditioner with Heat Pump – R454B Refrigerant

This dual-zone mini split system is capable of delivering 18,000 BTUs of cooling, as well as up to 18,000 BTUs of non-ducted heating through its reverse-cycle heat pump – an ideal solution for spaces up to 900 sq. ft. 

Not only is this system Energy Star certified with impressive energy efficiency ratings depending on its configuration, with non-ducted hitting 22.0 SEER2, 13.3 EER2, and a HSPF2 of 10.0, it also meets the rigid requirements for Cold Climate EnergyStar certification. 

Features include Friedrich’s Precision Inverter technology, as well as DiamonBlue Advanced Corrosion Protection coating on the outdoor coils to deter potential rust and deterioration over time, making this system ideal for harsh regions like coastal climates. It also uses R454B refrigerant, which has the lowest GWP (Global Warming Potential) on the market. 

Its built-in WiFi enables easy control from anywhere so long as you have access to the internet with the Friedrich ComfortPro app, Amazon Alexa or Google Home.
