The mini split AC and heat pump market continues double-digit growth every year because the equipment is efficient, cost-effective and offers versatile installation options. But what are the best mini split system brands? This guide covers the top ductless HVAC brands for single zone, multiple zone and a newer category of heat pump, the cold-climate mini split system.

If you’d like to research mini split HVAC basics, brands, prices, options and sizing a system for your home, our comprehensive Mini Split Buying Guide is packed with information.

The units on this top ductless HVAC list aren’t necessarily the most efficient. They are the mini split heat pumps that will give you durable performance you can count on for 15-20 years or more.

Best Single Zone Ductless Mini Split Units

A single-zone system is an outdoor unit (condensing unit) with one indoor unit (evaporator/air handler). The zone can be a single small bedroom or office or something as large as a spacious living room or garage or shared workspace. Units from 9,000 to 24,000 BTU are common.

In short, single zone units are used for spaces from less than 100 to more than 1,000 square feet.

This table gives the top single zone mini split units with basic features. There are additional details below.

Best Cold Climate Ductless Mini Split Heat Pumps

Heat pumps have been ruled out for use in very cold climates until recently. The cold-climate technology has improved significantly, and now many brands make units capable of heating effectively in temperatures well below freezing. They do it with traditional heat pump technology.

Among the models listed above are several capable of heating in freezing weather: Gree Crown+ (-22F), LG Multi V S (-13F).

Here are 3 more that stand out for heating effectively in the very coldest weather.

LG Ductless vs Fujitsu? Which is better?

Both are high-quality brands with advantages.

LG makes more systems, so you have better options to fit your needs. The brand also makes bigger condensing units (heat pumps) – up to 60,000 BTU/h capacity ideal for large multi-zone installations.

Fujitsu units range from 9,000 to 24,000 BTUs, so aren’t ideal for large homes. However, for space up to about 1,000 square feet depending on climate, Fujitsu is just right. Most Fujitsu ductless systems are more efficient than LG’s.

How good are Daikin ductless systems?

And can you recommend a Daikin mini split system model?

Much of today’s top ductless technology was invented at Daikin. The brand remains among the very best.

One thing to notice from the model reviews above is that Daikin offers the longest warranties in the industry – 12 years on both the compressor and parts.

We recommend the Daikin Aurora 20 Series for single zones and the Daikin MXS Series for multiple zones.

There are a few details above, but see our Daikin Mini Split Review and Guide for full details.

Gree ductless vs Mitsubishi. Which is better?

Mitsubishi is considered the best overall brand of mini split heat pump. Sales are phenomenal.

Gree has strong points though. Consumer reviews are excellent. And the Gree Sapphire has two benefits – the highest SEER rating (38) and that it functions to the lowest temperature (-22F).

You might enjoy our Review Guides to both brands:

Which is better, a single zone or two zone system?

Both have their benefits.

The single-zone system will cost less, of course, because it has one inside unit. If the space you want to heat and air condition is open, then a single-zone system will work.

The two-zone system, while costing more, gives you the advantage of two places for indoor units. This often leads to better airflow and temperature balance. If you have two+ rooms, like a one-bedroom apartment with an open living/dining area, the two-zone system is preferred.

How much does a ductless system cost?

Most homeowners pay $5,500 – $7,500 for their system. But it depends on home layout, how many indoor units you need and total heating and air conditioning capacity required.

Small single-zone systems cost less than $3,000. Large systems with many zones exceed $10,000.

Our Mini Split System Buying Guide has complete ductless system pricing plus information on choosing the right system for your needs.

This page mentions how important installation experience is. What can go wrong?

The most common mistakes are:

  • Not sizing the system properly, so you don’t get enough heat and air conditioning or too much, causing short-cycling which will damage the compressor
  • Not properly matching the outdoor condensing units to the indoor units in a multi-zone system
  • Putting in too little refrigerant.
  • Installing the indoor units in non-optimal locations.
  • Miswiring the system or thermostat.
