Buyers’ Guide

Mini split air conditioners are commonly selected for the separate house or office rooms. They serve as the perfect additions to the available central heating systems. Including the non-ducted ones that are filled with hot water, based on wood, gas or fuel-operated space heaters. The solutions perfectly suit the premises and utility spaces. Where ductworks can’t be installed. For example, basements, garages, workshops.

How Do Mini Splits Work?

The name “split” comes from the system construction as it always includes two basic units: an indoor and an outdoor one. The basic components of an air conditioner of this kind are:

  1. a heat pump or a condensing unit;
  2. piping, connections or lines;
  3. an indoor, air handling unit with an evaporator inside;
  4. a remote control.

Ductless mini splits are more energy-efficient and affordable as. They don’t feature the expensive and difficult to install ductworks. How does the refrigerant flow in this case? It circulates through the flexible piping that is compact, discreet and custom-designed, fitting the house or the room style. Commonly, 2 lines are included: for liquid and gas freon.

An evaporator includes a copper coil, an expansion valve and a fan with metal (commonly aluminum) fins. Cold (liquid) freon comes to the outdoor unit and starts boiling. Thanks to the heat energy released from the process, hot air is fanned out throughout the room.

Vice versa, the heat pump adopts the boiling refrigerant and cools it down when cooling is required in the summertime.

Benefits and Drawbacks of Mini Splits

Ductless systems are beneficial, as no heat or air is lost while being transferred through the ductwork. They are better in terms of:

  • air quality;
  • energy-efficiency;
  • ease of installation;
  • safety;
  • house design solutions.

Mini splits are easily-hidden, requiring less space to be mounted. However, they are not sufficient for large houses and offices. Additionally, they require some maintenance that includes the filters’ cleaning and charging with the refrigerant.

Mini Split Selection Issues

A mini split system is a pretty complicated device. It’s compact in comparison with a central system, however, it’s still very sophisticated, coming with multiple features. Thus, selecting the better mini split system that meets your needs, you may consider its:

  • energy efficiency;
  • durability;
  • the room size;
  • level of control;
  • adjustability and usability;
  • the brand reputation.

All the top-quality appliances I review herewith are single-zone. Sufficient for normal and medium-sized rooms. However, as every popular brand has its unique peculiarities, I would advise you to focus on your priorities. That is, Wi-Fi control, thermostat functionality or the advanced (anti-bacterial, activated carbon or electrostatic) filters.

As to the ease of mounting. The work requires advanced professional skills and long-time experience. I would still recommend hiring a team of licensed and certified contractors. However, the availability of the components and consumables still matter. So, I would advise you to estimate the total mini-splits’ cost. Including all the necessary parts to compare and contrast them.

Daikin vs Mitsubishi vs LG vs Fujistu Systems

Wondering who makes the top mini split air conditioner, consider your needs and priorities. I guess, if you’ve selected a top-quality appliance from one of these legendary brands, anyway that’s something. These products are quiet, energy-efficient, reliable and long-lasting.

However, Daikin, LG and Fujitsu devices feature the beneficial Wi-Fi options. Mitsubishi and Daikin mini splits come with the advanced motion sensors, being energy-efficient and comfortable. Mitsubishi’s internal unit is the quietest and the most suitable for low outdoor temperatures. According to the Quora forum, Mitsubishi mini-splits are more durable than Daikin devices.

Is Energy Efficiency So Important?

Being ready and willing to save on electricity bills, consider the SEER (Seasonal Energy-Efficiency Ratio) rating. It envisions the seasonal changes during the year. Calculated as the cooling BTU output to the energy consumed (watts per hour) during the full year.

Quite naturally, minimum SEER requirements depend on the climate within the state. For example, in California and the other southern states, it makes 14, in the northern states, as the DOE has imposed, SEER is to be not less than 13, since the beginning of 2015.

HSPF (Heating Seasonal Performance) rating is similar, showing heating output efficiency.

Final Verdict

I guess the better mini split system is WYS012-17 from Pioneer. As it’s smart, friendly, packed with the parts and consumables, essential for the installation. The appliance from Senville is the most energy-efficient. The Mitsubishi MZ-FH15NA set is the most user-friendly. Quiet, durable and able to filter the air pretty good. It suits the states with cold and temperate climates.
